Abstract

The Catholic Church’s claims concerning revelation, doctrinal authority, and divine guidance coexist with a historical record containing significant instances of institutional self-correction and acknowledgment of past wrongs. This tension raises an important but insufficiently examined epistemological question: What should the Church learn about the limits of ecclesial knowing from occasions on which it acknowledges that earlier judgments were seriously mistaken? This article examines two particularly instructive cases: the Galileo controversy, reconsidered by Pope John Paul II in 1992, and the Catholic Church’s historical entanglement with slavery, explicitly acknowledged by Pope Leo XIV in Magnifica Humanitas (2026). Rather than treating papal apologies primarily as exercises in institutional reconciliation, the article interprets them as acts of retrospective epistemic judgment. Drawing upon scholarship on doctrinal development, magisterial authority, moral change, ecclesial reform, and the history of science, the study employs Critical Synthetic Realist Methodology (CSRM) to integrate historical, theological, ethical, and epistemological analysis. Critical Synthetic Realism (CSR) supplies the central conceptual distinction between the objectivity of truth and the fallibility of historically situated human apprehension of truth. Its concept of epistemic fracture illuminates how communities genuinely committed to truth may nevertheless normalize distorted judgments through cultural inheritance, institutional interests, disciplinary overreach, and moral blindness. The article argues that Galileo and slavery do not constitute straightforward refutations of Catholic doctrines of indefectibility or papal infallibility. They reveal instead the theological necessity of distinguishing ecclesial indefectibility from ecclesial epistemic impeccability. Papal apologies should therefore be understood as evidence that fidelity to truth requires institutional correctability. The article concludes by proposing ecclesial epistemic humility as a theological and intellectual virtue with implications for doctrinal development, moral teaching, interdisciplinary dialogue, and the exercise of magisterial authority.

1. Introduction: The Epistemological Meaning of Ecclesial Repentance

What does it mean, epistemologically, when the Church says that it was wrong?

The question is deceptively difficult. Christian theology has long possessed conceptual resources for acknowledging sin within the Church. The New Testament itself presents the earliest Christian community neither as morally flawless nor as institutionally immune from conflict, misunderstanding, and correction. Peter can misunderstand the implications of the Gospel and be confronted by Paul (Gal. 2:11–14); communities founded by the apostles can fall into serious moral and doctrinal confusion; and the Church’s holiness can be confessed without requiring the personal holiness of every Christian. Catholic ecclesiology has therefore never depended upon the proposition that Christians, bishops, theologians, or popes are morally impeccable.

Epistemic failure presents a somewhat different problem. The Catholic Church does not understand itself merely as a voluntary association of religious seekers. It makes substantive claims concerning revelation and teaching authority. It holds that the deposit of faith has been entrusted to the Church, that the Holy Spirit assists the Church in preserving and interpreting that deposit, and that under carefully defined conditions the magisterium can teach definitively on matters of faith and morals (First Vatican Council, 1870/1990; Second Vatican Council, 1964, 1965). The possibility of serious historical error therefore raises questions extending beyond the moral failures of individual Christians. It touches the relationship among truth, authority, interpretation, history, and the conditions under which ecclesial judgments are formed.

The question has acquired renewed importance following Pope Leo XIV’s Magnifica Humanitas (2026). Although principally concerned with safeguarding human dignity in the age of artificial intelligence, the encyclical contains an extraordinary historical acknowledgment. In paragraph 176, Leo addresses the involvement of the Holy See and Catholic institutions in slavery and explicitly asks forgiveness for the ways ecclesiastical authority contributed to the legitimization of human enslavement (Leo XIV, 2026). The significance of such an acknowledgment extends beyond the moral repudiation of slavery. It necessarily compares two ecclesial moments: an earlier one in which practices or judgments were tolerated, defended, regulated, or institutionally embodied, and a later one from which those practices are judged morally unacceptable.

The structure of an apology therefore contains an implicit epistemology. To apologize meaningfully for an inherited institutional wrong is to affirm that the past ought to have been otherwise. It is to maintain that earlier actors failed, whether culpably or nonculpably, to perceive or act upon something that should have constrained their conduct. Ecclesial repentance consequently involves more than memory. It involves retrospective judgment.

Pope John Paul II’s reconsideration of the Galileo affair offers an earlier and particularly instructive parallel. In his 1992 address to the Pontifical Academy of Sciences, delivered after the conclusion of the work of the commission established in 1981 to study the Ptolemaic-Copernican controversy, John Paul II acknowledged errors in the handling of Galileo’s case (John Paul II, 1992). He drew attention especially to the failure of theologians to distinguish Scripture from historically conditioned interpretations of Scripture and to the problems that arise when theology pronounces upon matters beyond its proper competence. Importantly, the pope did not regard Galileo simply as an embarrassment belonging to a scientifically primitive past. He described the affair as containing a lesson with continuing relevance.

Galileo and slavery represent different kinds of cases and should not be collapsed into a single narrative of ecclesiastical error. The Galileo controversy concerned the interaction of biblical interpretation, natural philosophy, emerging scientific evidence, institutional authority, and disciplinary competence. Slavery concerns moral anthropology, human dignity, social structures, economic interests, biblical interpretation, colonialism, and the development of Christian moral consciousness. The differences are substantial.

Yet the cases converge upon a fundamental epistemological problem: How can a community sincerely committed to truth—and, in Catholic understanding, providentially entrusted with revelation—nevertheless fail to recognize important dimensions or implications of truth?

One response is to delimit narrowly the scope of Catholic infallibility. This response is theologically necessary but epistemologically insufficient. Neither Galileo’s condemnation nor the Church’s historical accommodation of slavery constituted an ex cathedra definition satisfying the conditions subsequently articulated at Vatican I. Catholic theology therefore need not choose between admitting these historical failures and abandoning the doctrine of papal infallibility.

But this observation does not dispose of the larger problem. The epistemologically significant fact is not simply that noninfallible statements can be wrong. That is almost tautological. The deeper problem concerns the degree of confidence with which religious communities can hold historically conditioned judgments, the institutional processes through which those judgments acquire authority, the capacity of cultural assumptions to masquerade as theological necessity, and the conditions under which correction becomes possible.

This distinction is central to the argument developed here. The historical failures considered in this article do not demonstrate that objective religious truth is impossible. Nor do they establish that all doctrine is provisional, that revelation is merely culturally constructed, or that ecclesial authority is inherently illegitimate. Such conclusions would move too quickly from the fallibility of knowers to the instability of truth itself.

Critical Synthetic Realism (CSR) offers an alternative. It maintains a realist distinction between reality and its apprehension while recognizing that human knowledge is mediated, situated, corrigible, and vulnerable to distortion (Asongu, 2026a). Truth does not become relative because human beings apprehend it imperfectly. On the contrary, correction is meaningful precisely because reality exceeds particular acts of knowing. A judgment can be corrected because the object of knowledge is not exhausted by the judgment made about it.

This epistemological position becomes especially important when applied to ecclesial history. The Church can possess authentic theological principles without having exhaustively perceived their implications. It can confess the imago Dei while failing to recognize fully what that confession demands in relation to slavery. It can affirm the authority of Scripture while confusing Scripture with a particular cosmological interpretation. It can defend objective truth while making historically conditioned judgments about what that truth requires.

The CSR concept of epistemic fracture names the conditions under which knowing becomes distorted without requiring the abandonment of realism (Asongu, 2026a). Epistemic fracture may arise from cognitive limitation, cultural inheritance, institutional interest, ideological commitment, disciplinary isolation, relations of power, psychological investment, or moral failure. These factors do not necessarily make knowledge impossible. They make humility and correction necessary.

Applied to ecclesiology, this yields the principal thesis of the present article: papal apologies and ecclesial acknowledgments of historical error should be understood not only as acts of repentance but also as evidence for the theological necessity of ecclesial epistemic humility. They reveal that a Church committed to objective truth must simultaneously cultivate institutional mechanisms and intellectual virtues capable of recognizing that its historically situated members may mistake partial apprehensions, inherited assumptions, or culturally conditioned judgments for the fullness of truth.

This article therefore proposes a distinction between ecclesial indefectibility and ecclesial epistemic impeccability. The former affirms that the Church does not cease to be the Church through historical failure and that God does not abandon the Church in its salvific vocation. The latter would imply something much stronger: that ecclesiastical institutions, authoritative traditions, or dominant theological judgments are effectively protected from serious epistemic distortion. Catholic theology requires the former; it need not—and historically cannot plausibly—require the latter.

The distinction permits a constructive rather than adversarial interpretation of papal apology. When the Church acknowledges past wrongs, it does not necessarily undermine its authority. It may instead demonstrate a deeper fidelity to truth by allowing reality to correct inherited judgments. Repentance, on this account, possesses an epistemic dimension. It is not merely sorrow for what was done; it is recognition that something was inadequately perceived, interpreted, or judged.

The argument has consequences extending well beyond Galileo and slavery. It bears upon doctrinal development, moral theology, biblical interpretation, relations between theology and the sciences, the authority of tradition, and the prudence required before contingent theological conclusions are elevated into irreversible formulations. The historical capacity to say “we were wrong” should influence the epistemic posture with which the Church says “we are certain.”

The challenge, then, is neither to dissolve Catholic confidence into skepticism nor to protect ecclesial authority through historical denial. It is to develop an account of religious knowing capable of sustaining realism without triumphalism, authority without epistemic absolutism, continuity without historical amnesia, and doctrinal conviction without the presumption that finite human apprehension is identical with divine knowledge.

2. Literature Review: Truth, Development, Fallibility, and Ecclesial Self-Correction

2.1 Doctrinal Development and the Problem of Historical Change

The problem addressed in this article belongs to a much older theological conversation concerning continuity and change in Christian doctrine. John Henry Newman’s An Essay on the Development of Christian Doctrine remains foundational because Newman rejected the assumption that historical change necessarily entails corruption. Christian doctrine, he argued, develops organically as implications contained within the life and faith of the Church become progressively articulated (Newman, 1845/1989). Development is therefore not simply the accumulation of additional propositions. It reflects the historical maturation of Christian understanding.

Newman’s importance for the present argument lies partly in his refusal to identify fidelity with mere repetition. A living tradition develops. Yet development also creates a criterion problem: how can authentic development be distinguished from corruption? Newman’s famous “notes” of genuine development were intended to address precisely this difficulty. His analysis acknowledged that historical continuity cannot be established merely by demonstrating verbal sameness across centuries. Ideas develop through encounter with new circumstances, questions, objections, and experiences.

The Second Vatican Council deepened this historical consciousness. Dei Verbum teaches that the apostolic tradition develops in the Church with the assistance of the Holy Spirit and speaks of growth in the understanding of the realities and words handed down (Second Vatican Council, 1965). Such language is incompatible with a purely static model of ecclesial knowledge. Revelation may be complete in Christ without implying that every implication of revelation has been exhaustively apprehended at every historical moment.

This distinction becomes particularly important in moral theology. Historical development sometimes concerns not merely the clarification of previously implicit propositions but substantial transformations in the Church’s moral judgment regarding social institutions. Noonan’s (2005) A Church That Can and Cannot Change is especially important here. Through detailed studies of slavery, usury, religious liberty, and marriage, Noonan argues that Catholic moral teaching has undergone genuine development while remaining anchored in its foundational commitment to the Gospel. His treatment of slavery is especially challenging because the historical record cannot easily be reduced to a narrative in which the Church consistently condemned slavery while secular society simply failed to listen. Christian theologians and institutions themselves participated in the moral assumptions that made slavery appear permissible.

Noonan’s argument has generated important criticism. Dulles (2005), for example, cautions against treating developments in social teaching as equivalent to reversals in dogmatic teaching. He distinguishes revealed doctrine from contingent social judgments, arguing that the application of enduring principles to changing social circumstances necessarily permits a degree of historical variability. This distinction is important. Social teaching cannot simply be treated as dogma under another name, and not every alteration in prudential judgment constitutes doctrinal contradiction.

Nevertheless, the distinction may actually sharpen the epistemological question rather than eliminate it. If the Church possesses enduring principles but can seriously misjudge their application, then theological epistemology must explain how such failures occur. The problem of slavery is especially difficult because the modern rejection of enslavement cannot adequately be explained simply by saying that social circumstances changed. The moral status of owning another human being is not merely a technical adaptation to altered economic conditions. Noonan’s historical argument suggests that Christian moral perception itself underwent development. Later Christians came to perceive dimensions of human dignity and domination that earlier Christians, despite possessing many of the same scriptural and theological resources, did not perceive adequately (Noonan, 2005).

This is precisely where doctrinal development intersects with epistemic humility. Development is possible because understanding is not exhaustive. But if understanding is not exhaustive, present theological judgments must themselves remain conscious of the historical conditions under which they are formed.

2.2 Ecclesial Authority and the Boundaries of Infallibility

Any argument concerning ecclesial fallibility must carefully distinguish different levels of Catholic teaching authority. Failure to do so produces an easy but misleading argument: the Church was wrong about Galileo or slavery; therefore, papal infallibility is false. This conclusion does not follow.

The First Vatican Council defined papal infallibility under specific conditions: when the Roman pontiff speaks ex cathedra, exercising his office as shepherd and teacher of all Christians, and definitively defines a doctrine concerning faith or morals to be held by the whole Church (First Vatican Council, 1870/1990). Vatican II situated this charism within the broader teaching office of the episcopal college and the Church’s reception of revelation (Second Vatican Council, 1964). Catholic theology has consequently distinguished infallible definitions from nondefinitive magisterial teaching, prudential judgments, disciplinary decisions, theological opinions, and the conduct of ecclesiastical institutions.

Francis Sullivan (1996) has shown how important these distinctions are for understanding the magisterium. Not everything taught authoritatively is taught infallibly, and not every ecclesiastical judgment possesses the same theological weight. The faithful response appropriate to teaching therefore cannot be determined simply by noting that a pope or ecclesiastical authority has spoken.

Yet precisely because the Catholic tradition recognizes gradations of authority, it also recognizes a realm of authoritative but corrigible ecclesial judgment. The existence of this realm raises an epistemological rather than merely canonical question: How should a Church conscious of its history exercise authority in matters in which error remains possible?

The question becomes more urgent when institutional authority reinforces a mistaken judgment. Galileo was not simply contradicted by individual theologians. His case involved ecclesiastical structures capable of imposing consequences upon dissent. Likewise, slavery was not merely the private vice of isolated Christians. It became embedded in social and ecclesiastical institutions. The epistemic problem therefore concerns not simply individual fallibility but institutionalized fallibility—the possibility that authority can amplify rather than correct an epistemic distortion.

This possibility has profound implications for the theology of authority. Authority can serve truth, but authority cannot substitute for truth. A proposition does not become true merely because an institution possesses the power to enforce it. Conversely, recognizing this distinction need not entail an anti-institutional ecclesiology. Institutions are indispensable vehicles of memory, interpretation, deliberation, and transmission. The issue is whether institutional authority understands itself as accountable to a truth that transcends its own formulations.

This realist constraint upon authority provides the bridge to the epistemological framework developed later in this article. If truth transcends the institution, then ecclesial fidelity occasionally requires institutional self-correction. Under such circumstances, correction is not necessarily a failure of tradition. It may constitute tradition’s recovery from its own historical distortions.

2.3 Galileo and the Epistemology of Disciplinary Boundaries

The Galileo affair has generated an enormous literature, and modern scholarship has complicated the simplistic image of an inevitable conflict between “science” and “religion.” Galileo’s dispute unfolded within a complex intellectual world in which scientific evidence, Aristotelian natural philosophy, biblical hermeneutics, ecclesiastical politics, personality, patronage, and the aftermath of the Reformation interacted (Brooke, 1991; Finocchiaro, 1989, 2005; Heilbron, 2010; McMullin, 2005).

The complexity matters because historical caricature would weaken rather than strengthen the argument of this article. Galileo did not possess all the evidence later available for heliocentrism; churchmen were not uniformly hostile to scientific inquiry; and several scientific objections to Galileo’s claims were reasonable within the knowledge available at the time. The episode should therefore not be reconstructed as a morality play populated by enlightened scientists and irrational clerics.

Nevertheless, the theological problem remains. Ecclesiastical judgment entered a domain in which empirical investigation would eventually demonstrate the inadequacy of the cosmological assumptions being defended. The significance of John Paul II’s (1992) reconsideration lies partly in his recognition that the controversy involved a failure to distinguish properly between Scripture and its interpretation. The Galileo affair thus becomes a case not merely of factual error but of epistemic jurisdiction: who is competent to make which kinds of claims, by what methods, and with what degree of certainty?

This issue remains contemporary. Theology necessarily makes claims that intersect with other disciplines because its subject matter includes human beings, creation, history, morality, and ultimate reality. Yet interdisciplinary engagement differs from disciplinary colonization. A theological framework may contribute to questions of meaning without thereby possessing technical competence in astrophysics, genetics, psychology, economics, or neuroscience. Conversely, scientific competence does not automatically confer expertise in metaphysics or theology.

The epistemic lesson of Galileo is therefore not that theology must retreat whenever science speaks. It is that intellectual authority requires an accurate understanding of the evidential and methodological limits appropriate to particular forms of inquiry.

That principle will prove central to the Critical Synthetic Realist analysis developed below. Epistemic fracture occurs not only when evidence is ignored but also when one domain of knowledge absolutizes its own competence and suppresses the corrective resources available from another.

3. Literature Review Continued: Slavery, Moral Development, and the Problem of the “Unknown Sin”

Noonan’s (2005) description of slavery as an “unknown sin” captures the epistemological problem with unusual force. The expression does not mean that slavery was literally unknown to Christians. Slavery was ubiquitous in the ancient Mediterranean world, embedded within economic and legal systems, explicitly mentioned in Scripture, discussed by theologians, and practiced within Christian societies. What remained inadequately known was its moral character.

That distinction is crucial. One may possess abundant factual knowledge of an institution while remaining morally blind to what that institution actually means for the persons subjected to it.

The biblical record itself presents interpretive difficulties. Neither the Hebrew Scriptures nor the New Testament offers the straightforward abolitionist condemnation modern readers might expect. Paul’s Letter to Philemon radically reframes Onesimus as a brother, yet it does not present a systematic repudiation of slavery as an institution. Patristic and medieval Christian traditions likewise contain resources for affirming universal human dignity alongside accommodation to existing structures of servitude. Noonan’s historical study demonstrates how long Christian moral reasoning could coexist with slaveholding before the institution came to be regarded as fundamentally incompatible with Christian anthropology (Noonan, 2005).

The point should not be deployed anachronistically. Historical moral judgment requires attention to the conceptual worlds within which persons acted. Yet historical contextualization cannot mean that moral evaluation becomes impossible. Indeed, Pope Leo XIV’s apology presupposes precisely the opposite. Magnifica Humanitas does not merely observe that earlier centuries possessed different social conventions. It evaluates the past morally from the standpoint of human dignity and acknowledges ecclesial participation in structures now recognized as contrary to that dignity (Leo XIV, 2026).

This creates the central problem around which the remainder of the article turns. If the Church can now recognize as morally wrong something that Christians once tolerated, practiced, or justified, what changed? The truth? Human dignity? Revelation? Or the Church’s apprehension of what truth and revelation required?

A realist account cannot plausibly answer that human dignity itself came into existence only when modern consciousness recognized it. If enslaved persons possessed dignity in the fifteenth, sixteenth, or seventeenth centuries, then the moral reality preceded its adequate ecclesial recognition. The development occurred primarily on the side of the knower.

Here the problem of slavery becomes an especially important test case for theological epistemology. It suggests that a community may possess true theological premises while failing for generations to draw their morally necessary implications.

The imago Dei was not discovered in the nineteenth century. The command to love one’s neighbor was not added to Christianity by modern abolitionists. The universality of redemption was not unknown to medieval theology. What changed was, among other things, the depth with which those principles were brought into judgment upon inherited structures of domination.

The question, therefore, is no longer merely whether Catholic teaching develops.

It is why the Church sometimes needs history to teach it what its own deepest theological commitments require.

That question demands a methodology capable of holding history, theology, moral experience, institutional power, and epistemology together. It is to that methodological task that the next section turns.

4. Methodology: Critical Synthetic Realist Methodology and Ecclesial Self-Correction

The questions raised by Galileo and slavery cannot adequately be addressed within a single disciplinary framework. They are simultaneously historical, theological, philosophical, ethical, hermeneutical, and institutional. A purely historical inquiry may reconstruct what ecclesiastical authorities believed without determining whether those beliefs were epistemically warranted. A theological approach may explain the formal boundaries of magisterial authority without sufficiently examining the historical processes through which particular judgments acquired ecclesiastical legitimacy. Moral philosophy can evaluate slavery as an institution but may overlook the theological categories through which Christians historically interpreted it. Conversely, an exclusively doctrinal approach risks insulating ecclesial claims from precisely the historical evidence requiring explanation.

This study therefore employs Critical Synthetic Realist Methodology (CSRM), a methodological extension of Critical Synthetic Realism (CSR). CSRM proceeds from the premise that complex realities are rarely exhausted by a single explanatory layer. It consequently seeks an interdisciplinary synthesis in which different forms of evidence are critically assessed according to their appropriate epistemic competence and subsequently integrated into a more comprehensive judgment (Asongu, 2026a).

The word synthetic is important but should not be misunderstood. Synthesis does not mean indiscriminately combining incompatible claims or constructing artificial compromises among competing perspectives. Nor does methodological pluralism imply that all interpretations possess equivalent epistemic value. CSRM remains realist: reality places constraints upon interpretation. Some explanations correspond more adequately to the evidence than others. Synthesis therefore follows criticism rather than replacing it.

Four methodological commitments are especially relevant to the present study.

First, ontological realism maintains that reality exceeds human interpretation. Galileo's astronomical claims were ultimately answerable to a physical universe whose structure did not depend upon ecclesiastical judgment. Similarly, the dignity of enslaved persons did not originate when Christian institutions eventually recognized slavery as morally unacceptable. The reality to which moral and scientific judgments refer possesses a degree of independence from the communities making those judgments.

Second, epistemic fallibilism recognizes that access to reality is mediated and corrigible. Human beings know through historically situated conceptual frameworks, languages, traditions, institutions, disciplinary methods, social relationships, and prior assumptions. This mediation does not make truth inaccessible, but it does make intellectual humility necessary.

Third, critical interdisciplinarity requires that claims be evaluated according to the evidentiary competence of the disciplines involved. Historical propositions require historical evidence. Empirical scientific questions require methods appropriate to scientific inquiry. Theological claims must be assessed through theological reasoning, Scripture, tradition, and the relevant doctrinal framework. Ethical judgments require attention to moral principles, human experience, consequences, relationships, and the nature of the persons affected. No discipline is permitted simply to absorb all others into its own explanatory vocabulary.

Fourth, synthetic judgment seeks an account capable of incorporating insights surviving critical examination across these domains. The goal is neither reduction nor fragmentation but an increasingly adequate approximation of reality.

This methodology is particularly suited to ecclesial self-correction because such correction necessarily occurs across time and across epistemic domains. The Church's reconsideration of Galileo required developments in scientific knowledge, historical scholarship, biblical hermeneutics, and theological reflection. Its developing judgment concerning slavery involved encounters among Scripture, anthropology, moral experience, abolitionist testimony, changing social structures, theological reasoning, and deepening reflection upon human dignity.

CSRM therefore asks not simply whether earlier ecclesial judgments were wrong but how particular configurations of knowledge made those judgments appear reasonable, authoritative, or morally permissible at the time, and what subsequently enabled their correction.

4.1 Epistemic Fracture as an Analytical Category

The principal CSR concept employed in this analysis is epistemic fracture. Epistemic fracture describes a condition in which the relationship between reality and its apprehension becomes distorted, fragmented, or insufficiently integrated (Asongu, 2026a). It does not necessarily imply deliberate deception or culpable ignorance. A person or institution may sincerely pursue truth while operating within conceptual structures that obscure important dimensions of the reality under consideration.

This distinction is essential for historical analysis. It would be intellectually simplistic to assume that everyone who opposed Galileo was knowingly hostile to truth or that every Christian who failed to advocate abolition consciously rejected human dignity. Such judgments would substitute moral caricature for explanation.

Epistemic fracture permits a more nuanced account. Individuals may reason conscientiously within defective frameworks. Institutions may preserve genuine truths while simultaneously perpetuating serious distortions. A theological tradition may contain conceptual resources capable of correcting a moral wrong without immediately recognizing their implications.

For analytical purposes, the cases examined here suggest at least four forms of ecclesial epistemic fracture.

Disciplinary epistemic fracture occurs when a field exceeds the warranted boundaries of its competence. Galileo provides the paradigmatic example considered here: theological and ecclesiastical authority became entangled with claims concerning the physical structure of the cosmos that required empirical adjudication.

Hermeneutical epistemic fracture occurs when an interpretation is insufficiently distinguished from the reality or authoritative text being interpreted. When a historically conditioned reading of Scripture becomes identified with Scripture itself, challenges to the interpretation may consequently be perceived as challenges to revelation.

Moral epistemic fracture occurs when persons or communities possess relevant moral principles yet fail adequately to perceive their implications for particular persons, practices, or institutions. The history of slavery provides a particularly disturbing example.

Finally, institutional epistemic fracture occurs when structures of authority, interest, prestige, economic dependence, or social conformity reinforce distorted judgments and make correction more difficult. Institutions can preserve knowledge across generations, but they can also stabilize error.

These categories overlap. Galileo involved hermeneutical as well as disciplinary and institutional factors. Slavery involved moral, hermeneutical, economic, political, and institutional factors. CSRM therefore resists monocausal explanations.

4.2 Papal Apology as Retrospective Epistemic Evidence

The present study treats papal apologies as a distinctive form of evidence. They are not assumed to provide exhaustive or historiographically neutral accounts of the past. Popes addressing historical wrongs are engaged in theological and pastoral interpretation rather than detached historical description. Their statements must therefore be read critically alongside historical scholarship.

Nevertheless, papal acknowledgments possess particular significance for the argument developed here because they represent internal ecclesial judgments upon earlier ecclesial conduct. The criticism is not imposed exclusively from outside the Catholic tradition. The Church, through its highest pastoral office, participates in the retrospective judgment.

This matters epistemologically. An apology implicitly establishes a temporal comparison:

what was believed or done then → what is judged now → what ought to have been recognized.

The third element is indispensable. Without it, an apology would amount merely to saying that contemporary preferences differ from historical ones. Genuine repentance presupposes normative continuity beneath historical change. Something about the earlier conduct was deficient, not merely unfashionable.

This structure makes papal apology particularly compatible with critical realism. Truth and moral reality remain sufficiently stable for one historical moment to judge another, while human apprehension remains sufficiently fallible for correction to occur.

The methodology therefore avoids two opposite errors. It rejects presentism, which assumes that contemporary judgments are correct merely because they are contemporary. It also rejects historical relativism, which makes moral criticism impossible by treating every judgment as wholly captive to its historical context.

The question throughout is comparative and realist: Which interpretation better accounts for the relevant reality, evidence, theological principles, and human consequences?

5. Galileo: Disciplinary and Hermeneutical Epistemic Fracture

Few episodes in Christian history have acquired as much symbolic significance as the Galileo affair. In popular imagination, Galileo often represents scientific reason persecuted by religious dogmatism. Historians have demonstrated that this picture is substantially too simple (Brooke, 1991; Finocchiaro, 1989, 2005; Heilbron, 2010; McMullin, 2005). Nevertheless, correcting the caricature must not become a means of avoiding the epistemological significance of the episode.

Galileo Galilei's support for Copernican heliocentrism developed during a period when the empirical evidence was still contested. Scientific objections to heliocentrism were not necessarily irrational by the standards of early seventeenth-century astronomy. The absence of observable stellar parallax, questions concerning terrestrial motion, and the continuing explanatory power of modified geocentric systems meant that the scientific debate was considerably more complex than later accounts sometimes suggest (Finocchiaro, 2005; Heilbron, 2010).

Nor was the Catholic Church uniformly opposed to astronomy. Jesuit scientists made significant contributions to astronomical observation, and ecclesiastical institutions participated substantially in early modern scientific culture (Heilbron, 1999). Galileo himself understood his scientific work as compatible with Christian faith.

The epistemic problem emerged when astronomical controversy became entangled with biblical interpretation and ecclesiastical authority.

5.1 Scripture and the Confusion of Interpretation with Revelation

Galileo recognized that heliocentrism raised hermeneutical questions because biblical passages appeared, when interpreted literally within the prevailing cosmology, to describe a stationary Earth and a moving sun. Joshua's command that the sun stand still (Josh. 10:12–13) became an obvious point of controversy.

Galileo's response was not to reject Scripture but to distinguish the salvific purpose of Scripture from the technical investigation of nature. In his famous letter to the Grand Duchess Christina, he argued that Scripture and nature ultimately derive from the same God and therefore cannot genuinely contradict one another, even though biblical language may accommodate itself to ordinary human understanding (Galilei, 1615/1957).

The position has profound hermeneutical significance. If Scripture is true but human interpretations of Scripture remain fallible, then apparent conflict between empirical evidence and biblical language may require reinterpretation rather than rejection of either revelation or science.

John Paul II (1992) would later identify precisely this problem. Reflecting upon the Galileo affair, he noted that theologians of the period failed adequately to distinguish the Bible itself from particular interpretations of the Bible. That failure transformed a question about interpretation into a perceived challenge to revelation.

Here the concept of hermeneutical epistemic fracture becomes useful. The fracture does not occur because interpretation is avoidable; all textual understanding requires interpretation. It occurs when interpreters cease to recognize the interpretive character of their own judgments.

At that point, disagreement becomes dangerous. If my interpretation is functionally identified with revelation itself, questioning my interpretation appears equivalent to questioning God.

The Galileo affair thus exposes a recurring danger in religious epistemology: the sacralization of interpretation.

This danger is not confined to premodern biblical exegesis. Religious communities in every period can become insufficiently conscious of the historical, linguistic, philosophical, and cultural assumptions through which authoritative texts are interpreted. Epistemic humility begins when the interpreter recognizes the difference between the authority of revelation and the authority claimed for a particular interpretation of revelation.

5.2 Disciplinary Overreach

The second epistemic fracture concerns disciplinary competence.

Theology possesses legitimate interests in creation, human nature, providence, and the intelligibility of the cosmos. It does not follow that theological authority possesses methodological competence to determine the orbital relations among celestial bodies.

This distinction seems obvious after the development of modern science. It was considerably less obvious in the seventeenth century, when disciplinary boundaries differed substantially from their contemporary forms. Nevertheless, that historical qualification does not remove the epistemic lesson.

A discipline exceeds its legitimate authority when it attempts to settle questions for which its methods cannot provide adequate evidence.

Galileo therefore represents more than an episode in the relationship between Christianity and astronomy. It exemplifies a general epistemic principle: authority must remain proportionate to competence.

This principle applies in both directions. Science cannot establish theological conclusions simply through empirical measurement, just as theology cannot determine scientific conclusions through ecclesiastical authority. Interdisciplinary synthesis requires dialogue precisely because reality exceeds the methodological competence of any single discipline.

From a CSRM perspective, Galileo illustrates the consequences of failed synthesis. Scientific evidence, biblical interpretation, philosophy of nature, and theology were not adequately differentiated before being integrated. Instead, a particular synthesis—Aristotelian-Ptolemaic cosmology combined with particular biblical interpretations—had acquired sufficient cultural and theological authority that challenges to one component destabilized the entire structure.

This is an important characteristic of epistemic fracture: a partial framework becomes mistaken for reality as a whole.

5.3 Authority and the Amplification of Error

The Galileo affair also illustrates the institutional dimension of epistemic fracture. Individual error is epistemologically ordinary. Institutional error becomes more consequential because institutions possess mechanisms capable of enforcing judgments, marginalizing dissent, and reproducing assumptions across generations.

When an institution possesses religious authority, the danger is intensified because disagreement may be framed not simply as intellectual dissent but as disobedience or unfaithfulness.

This does not mean authority is intrinsically opposed to inquiry. Scientific communities themselves possess authorities, paradigms, disciplinary gatekeepers, and mechanisms of exclusion. Universities, governments, professional organizations, and journals can all stabilize mistaken consensus. The problem is therefore not uniquely ecclesiastical.

Religious authority, however, introduces an additional dimension: claims may acquire sacred weight.

The theological significance of John Paul II's reconsideration of Galileo therefore lies not simply in acknowledging that some churchmen held an incorrect astronomical position. It lies in recognizing that ecclesiastical structures became implicated in the enforcement of a judgment that exceeded the epistemic warrant available to them.

John Paul II (1992) drew precisely the appropriate conclusion by refusing to treat Galileo as a closed historical episode. The affair contained, he argued, a lesson relevant to analogous situations that might emerge in the future.

That acknowledgment is itself an act of ecclesial epistemic humility.

It says, in effect, that the Church must learn not merely what was wrong but how the conditions for error arose.

6. Slavery: Moral and Institutional Epistemic Fracture

If Galileo demonstrates the danger of disciplinary overreach, slavery raises an even more troubling question. The problem is not principally that Christians lacked information. They knew slavery existed. Many lived within societies structured by it. Some owned enslaved persons. Others regulated slavery, benefited economically from it, or developed theological arguments capable of accommodating it.

The epistemological problem is therefore not ignorance of slavery's existence.

It is failure adequately to recognize slavery's moral meaning.

6.1 Theological Resources and Moral Blindness

Christianity possessed, from its beginnings, theological principles with potentially radical implications for slavery. Genesis presents human beings as created in the image of God (Gen. 1:26–27). The New Testament proclaims a salvation transcending ethnic and social divisions. Paul famously declares that in Christ there is neither Jew nor Greek, slave nor free (Gal. 3:28). The commandment of neighbor love occupies a central place within Christian ethics, while the incarnation and redemption establish a theological anthropology in which every person possesses profound significance before God.

Yet possession of these principles did not produce immediate abolitionism.

This fact is epistemologically significant.

It demonstrates that possessing a true principle is not equivalent to perceiving all of its implications.

Moral reasoning occurs through interpretation. Principles must be brought into relation with concrete institutions, relationships, practices, and experiences. That process can fail.

Christian interpreters could affirm that enslaved persons possessed souls while simultaneously accepting their legal ownership. They could proclaim spiritual equality while maintaining social hierarchy. They could interpret Paul's exhortations to slaves and masters as legitimating an institution rather than as pastoral counsel addressed to persons living within an inherited social order.

Such reasoning demonstrates what may be described as moral compartmentalization. Truths affirmed at one level fail to penetrate structures operating at another.

CSR's concept of epistemic fracture helps explain this phenomenon. Knowledge becomes fragmented. Theological anthropology, economic practice, political structures, biblical interpretation, and the lived experience of enslaved persons fail to confront one another adequately. The synthesis necessary for moral recognition does not occur.

6.2 The Epistemology of Privilege

Slavery also reveals something Galileo does not expose as clearly: social location affects moral perception.

Those who benefit from an institution do not encounter it epistemically in the same way as those who suffer under it.

This does not mean that truth is reducible to social location. Such a conclusion would contradict the realism defended here. An enslaved person is not automatically correct about every moral question, nor is a slaveholder automatically incapable of truth. Rather, social location affects the evidence, experiences, interests, and assumptions available to the knower.

Moral epistemology must therefore take testimony seriously.

The history of abolition illustrates the importance of allowing the experiences of those subjected to domination to enter moral deliberation. Narratives of enslavement did not create the dignity of enslaved persons. They made dimensions of an existing moral reality more difficult for dominant communities to ignore.

This distinction is essential for avoiding relativism. Experience does not manufacture truth; it can disclose truth.

Theologically, this insight resonates with the biblical tradition's recurring attention to voices from the margins—the widow, orphan, stranger, poor, oppressed, and socially excluded. Such attention is not merely charitable. It can be epistemically corrective.

A Church that listens only to those occupying positions of institutional security risks systematically filtering reality through the experiences of those least exposed to the consequences of its judgments.

6.3 Institutional Interest and the Stabilization of Moral Error

The problem becomes deeper when moral blindness intersects with institutional interest.

Slavery was not simply an abstract philosophical proposition. It was an economic system. Wealth, land, political power, colonial expansion, commercial networks, and social status became entangled with human bondage. Ecclesiastical institutions existed within these structures rather than outside them.

This matters because interests can influence cognition without necessarily producing conscious dishonesty.

Human beings are exceptionally capable of developing moral rationalizations for arrangements from which they benefit. Institutions are capable of doing the same collectively.

The epistemic fracture produced by slavery therefore cannot be understood solely as incorrect biblical interpretation. It emerged from a synthesis already distorted by economic, political, racial, cultural, and institutional forces.

Leo XIV's Magnifica Humanitas is significant precisely because it refuses to externalize this history. The Church's present condemnation of slavery is accompanied by acknowledgment of ecclesial participation in its historical legitimization (Leo XIV, 2026). The apology thereby disrupts a comforting narrative in which Christianity consistently possessed the correct moral judgment while the surrounding world simply refused to obey it.

The reality was more complicated.

There were prophetic Christian voices opposing forms of enslavement. There were papal interventions condemning particular abuses. There were theological resources capable of supporting abolition. Yet there were also accommodations, ambiguities, participation, and failures.

Epistemic humility requires remembering both.

6.4 From Moral Development to Epistemic Correction

Noonan's (2005) analysis of change in Catholic moral teaching is especially important at this point. His historical work demonstrates that development cannot always be described merely as applying an unchanged teaching to new circumstances. In some cases, the moral judgment itself becomes more adequate.

From a realist perspective, however, development cannot mean that slavery became intrinsically wrong only when Christians recognized it as such.

The more coherent explanation is epistemic.

The moral reality was more stable than its historical apprehension.

Enslaved persons possessed human dignity before ecclesiastical institutions adequately defended it. Their suffering was morally relevant before dominant theological frameworks fully incorporated it. Christian anthropology contained resources for a more adequate judgment before those resources were synthesized into an unequivocal rejection of slavery.

Moral development can therefore be understood, at least partly, as epistemic correction.

This formulation avoids two extremes. Against relativism, it affirms that there was something objectively wrong to recognize. Against ahistorical triumphalism, it acknowledges that recognition was incomplete and painfully slow.

6.5 Leo XIV and the Epistemological Meaning of Apology

The importance of Leo XIV's acknowledgment is therefore not exhausted by the words of contrition themselves.

The apology represents a contemporary ecclesial judgment upon earlier ecclesial participation in a moral wrong. It establishes continuity and discontinuity simultaneously.

Continuity exists because the contemporary judgment appeals to theological principles deeply rooted in Christianity: human dignity, creation, redemption, freedom, and the rejection of treating persons as objects.

Discontinuity exists because those principles are now applied in ways that expose the inadequacy of earlier ecclesial practice.

This is doctrinal and moral development understood through a realist epistemology.

The Church does not need to say that truth changed.

It needs to acknowledge that its apprehension and application of truth changed.

And once that admission is made, a further question becomes unavoidable.

If Christians of earlier centuries could confidently inhabit social and theological frameworks that obscured a moral reality now judged incompatible with human dignity, what warrants the assumption that contemporary Christians are entirely free from analogous forms of blindness?

That question is not an argument for skepticism.

It is the beginning of epistemic humility.

7. From Papal Apology to Ecclesial Epistemic Humility

The comparison between Galileo and slavery reveals an important pattern. In neither case was the fundamental problem simply absence of truth.

The natural world existed independently of the cosmology ecclesiastical authorities preferred. Human dignity existed independently of Christian society's willingness fully to recognize it.

The failures occurred principally within the relationship between the knower and the known.

Galileo reveals what happens when inherited interpretation, disciplinary authority, and institutional power become insufficiently open to correction from empirical reality.

Slavery reveals what happens when theological principles, moral experience, institutional interests, social hierarchy, and the testimony of suffering persons remain insufficiently integrated.

Both are therefore cases of epistemic fracture, although the fractures differ in form.

More importantly, both eventually generated forms of ecclesial correction.

This suggests that papal apology should be interpreted as more than retrospective moral regret. It represents what may be called an ecclesial epistemic event: an institutional recognition that an earlier configuration of judgment failed adequately to correspond to reality.

The theological significance of such an event is considerable.

The Church is effectively acknowledging:

We know now that something was not adequately known then.

That proposition raises questions concerning the relationship among revelation, tradition, authority, historical development, and human fallibility. Yet it need not destabilize Catholic theology.

It may instead provide the foundation for a more credible theology of ecclesial authority—one in which the Church's commitment to truth is demonstrated not by claiming never to require correction, but by developing the capacity to recognize when correction is required.

The critical distinction, therefore, is not between a Church that changes and a Church that does not.

It is between change as capitulation to historical fashion and correction as deeper conformity to truth.

Critical realism makes that distinction possible.

And it leads directly to the central constructive proposal of this study: the distinction between ecclesial indefectibility and ecclesial epistemic impeccability, and the corresponding recovery of epistemic humility as an ecclesial virtue.

8. Ecclesial Indefectibility and the Myth of Epistemic Impeccability

The historical evidence considered above creates a problem only if ecclesial fidelity is confused with epistemic perfection. Catholic theology need not make that confusion. Indeed, a more careful account of ecclesial authority suggests that the Church’s continuity through history is better understood in terms of indefectibility than in terms of any generalized immunity from error.

Indefectibility concerns the Church’s persistence in its fundamental identity and salvific mission. It does not require that every ecclesiastical judgment, interpretation, disciplinary decision, social practice, or theological consensus be correct. The distinction is essential because the historical record would otherwise place Catholic ecclesiology under unnecessary pressure. If every serious ecclesial error threatened the Church’s very identity, then every act of institutional repentance would become a theological crisis.

A stronger distinction is therefore required between ecclesial indefectibility and ecclesial epistemic impeccability.

The first can be affirmed within classical Catholic theology. The second should be rejected.

By ecclesial epistemic impeccability is meant the assumption—sometimes explicit, more often implicit—that ecclesiastical institutions, authoritative theological traditions, or dominant magisterial judgments are effectively insulated from serious epistemic distortion. Such an assumption may never be formally defined, yet it can function practically whenever deference to authority becomes so extensive that the possibility of correction is treated as disloyalty.

This distinction parallels the more familiar distinction between holiness and sin within the Church. Catholic theology can call the Church holy while acknowledging grave sins committed by its members and institutions. Holiness is not equivalent to historical moral impeccability. Likewise, fidelity to truth need not imply epistemic impeccability.

The analogy should not be pressed too far, but it is illuminating.

A Church can be genuinely ordered toward truth while still misunderstanding particular aspects of reality. It can preserve revelation while interpreting certain dimensions of it inadequately. It can possess an authentic tradition while also carrying within that tradition historically conditioned judgments that require purification.

This possibility is particularly important when ecclesial authority interacts with inherited cultures. Tradition is never transmitted in a cultural vacuum. Christian teaching takes historical form through philosophical categories, legal institutions, linguistic conventions, political structures, educational systems, and social assumptions. Some of these become fruitful vehicles of theological articulation; others become obstacles.

Congar’s reflections on reform remain important here because he refused to identify reform with rejection of tradition. Authentic reform, in his account, often involves returning more deeply to the sources of the Christian tradition while correcting historical accretions that have obscured them (Congar, 2011). This is a profoundly anti-relativist account of change: correction occurs for the sake of fidelity.

A similar insight appears in Newman’s account of doctrinal development. Development is not betrayal merely because later formulations differ from earlier ones. The relevant question is whether development preserves and more adequately unfolds the underlying reality of faith (Newman, 1845/1989).

This provides an important safeguard for the argument developed here. Ecclesial epistemic humility does not require the Church to place every belief perpetually under suspicion. Nor does it deny that some teachings may be held definitively. Rather, humility concerns the posture adopted in moving from revelation to interpretation, from principle to application, from theological reasoning to authoritative formulation.

The stronger the claim of irreversibility, the stronger the epistemic responsibility.

That proposition becomes especially important in light of historical self-correction.

8.1 Authority Is Not Omniscience

Religious authority easily acquires epistemic meanings beyond those formally claimed for it. A bishop may issue a pastoral judgment, yet the faithful may hear it as theological certainty. A curial decision may arise from contingent historical circumstances but later be remembered as if it reflected immutable doctrine. A widespread theological opinion may acquire such institutional prestige that its historical contingency becomes invisible.

These dynamics illustrate a broader problem in institutional epistemology. Authority often affects not simply what people are required to do but what they come to perceive as thinkable.

Where authority is strong, dissent becomes costly. Costly dissent may reduce the diversity of viewpoints available to a community. Reduced diversity can weaken error-correction. Once that occurs, institutional confidence may increase precisely as epistemic vulnerability grows.

This mechanism is not unique to the Church. It appears in governments, universities, scientific organizations, corporations, and ideological movements. Every institution develops mechanisms for maintaining coherence, and every mechanism of coherence can become a mechanism of exclusion.

The theological question is how a Church that claims divine assistance can remain institutionally open to correction without undermining legitimate authority.

The answer requires distinguishing authority from omniscience.

Authority concerns the legitimate right and responsibility to teach, govern, interpret, and preserve communal identity. Omniscience concerns exhaustive and error-free knowledge. The two should never be conflated.

Indeed, the exercise of authority may become more credible when it publicly acknowledges its epistemic conditions and limits. A teacher who distinguishes certainty from probability does not thereby cease to teach. A court that allows appeals does not thereby deny the legitimacy of judgment. A scientific community that revises a theory does not thereby abandon science.

Likewise, an ecclesial community capable of self-correction does not thereby cease to possess authority.

It may demonstrate that its authority remains accountable to truth.

8.2 The Epistemology of Reception

Catholic tradition has also recognized, although unevenly, that doctrine is not simply transmitted mechanically from hierarchy to passive recipients. Reception matters.

Theological scholarship on reception emphasizes that conciliar and magisterial teachings become historically effective through processes of interpretation, appropriation, liturgical embodiment, theological reflection, and lived practice (Congar, 1985; Rush, 2004).

This does not mean that truth is created by majority opinion. Reception cannot simply be reduced to sociological popularity. Yet it does reveal that teaching occurs within a living ecclesial body rather than through unilateral transmission alone.

The history of doctrinal development suggests that theological insight may arise from multiple locations: bishops, theologians, religious communities, lay movements, scientific inquiry, moral experience, and the testimony of those affected by particular practices.

The abolition of slavery illustrates this pluriform process. Moral insight did not descend through a single institutional channel. It emerged through contested interactions among Christian conscience, social movements, political struggles, testimony from enslaved persons, theological argument, and changing understandings of rights and dignity.

Such history suggests that ecclesial epistemology should take seriously the possibility that truth can become visible through voices not initially occupying positions of authority.

The principle is not democratization for its own sake. It is epistemic breadth.

A community seeking truth should attend to the widest relevant range of evidence.

That is fundamentally compatible with CSRM, which rejects explanatory monopolies and seeks critical synthesis across domains of knowledge.

9. Papal Apology as Institutional Metanoia

Christian theology traditionally understands metanoia as conversion—a turning of mind and life toward God. Repentance is not merely emotional regret. It requires altered perception, judgment, and action.

This concept can illuminate papal apology.

When ecclesial authorities apologize for historical wrongs, they do more than express sorrow. They reinterpret the past from a transformed moral horizon. The apology therefore contains a cognitive dimension: something previously normalized is now recognized as incompatible with values the community understands as integral to its own identity.

This may be described as institutional metanoia.

The term must be used cautiously because institutions do not possess consciousness in exactly the same way as persons. Yet institutions do preserve memories, practices, norms, policies, and authoritative interpretations. They can therefore undergo processes functionally analogous to conversion: acknowledgment, reinterpretation, repudiation, reform, and changed practice.

Papal apologies offer particularly visible examples because the symbolic representative of ecclesial continuity simultaneously acknowledges discontinuity with aspects of the ecclesial past.

The structure is paradoxical but theologically productive.

The pope speaks as heir to the tradition while acknowledging that elements within that tradition’s historical embodiment require repentance.

This is not self-annihilating.

It is possible only because identity is deeper than error.

9.1 Apology Requires a Realist Moral Grammar

The possibility of meaningful apology also reinforces the realist argument developed throughout this article.

If all moral judgments were merely products of historical communities, there would be little basis for saying that earlier Christians ought to have acted differently. One could say only that contemporary Christians prefer different values.

But this is not how papal apologies function.

When the Church asks forgiveness for historical wrongdoing, it implicitly affirms that moral reality transcends both past and present communities. The past can be judged because human dignity was real even when inadequately recognized.

Repentance therefore depends upon a realist moral grammar.

The wrong was wrong before the apology.

The apology acknowledges rather than creates the moral truth.

This insight is especially important for CSR because it demonstrates how realism and historical development can coexist. Moral truth can remain objective while moral knowledge develops. The epistemic shift occurs in the human community rather than in moral reality itself.

This model also avoids the temptation to idealize the present. Contemporary judgments remain historically situated. Present moral insight may be more adequate in some respects and deficient in others.

A realist account therefore permits criticism in both directions.

The past can correct the present, and the present can correct the past.

Tradition becomes dialogical rather than merely cumulative.

9.2 Repentance as Epistemic Correction

The theological significance of apology becomes still clearer when repentance is understood as epistemic correction.

Sin frequently involves distorted perception. Persons rationalize self-interest, misrecognize others, minimize harm, absolutize partial goods, and reinterpret evidence in ways that protect preferred identities. Moral conversion therefore often requires seeing differently before acting differently.

This relationship between perception and morality has deep roots in Christian spirituality. Augustine understood disordered love as affecting judgment; Aquinas treated moral virtue as relevant to practical reasoning; contemporary virtue epistemology has likewise emphasized the relationship between intellectual character and reliable knowing (Aquinas, 1265–1274/1981; Zagzebski, 1996).

Institutions can display analogous patterns. Where institutional identity becomes tied to the correctness of past judgments, evidence threatening those judgments may be resisted. The more costly admission becomes, the stronger the incentives for rationalization.

Public apology interrupts this dynamic.

It permits the institution to say: continuity does not require pretending that every inherited judgment was correct.

This is why apology can strengthen rather than weaken authority.

Authority becomes less dependent upon retrospective infallibilism and more visibly committed to truth.

9.3 From Institutional Defense to Institutional Learning

The shift from defensiveness to learning is crucial.

Institutions commonly respond to criticism by distinguishing themselves from their worst historical expressions. Such distinctions may be legitimate. The Church is not reducible to every action performed by Christians, and doctrinal teaching should not be confused with every historical ecclesiastical practice.

Yet these distinctions become evasive if their primary function is to protect institutional reputation rather than understand the mechanisms of failure.

The more productive question is not simply:

Was this technically an infallible teaching?

It is also:

Why did ecclesiastical authorities become sufficiently confident in this judgment that dissent, correction, or alternative interpretation became difficult?

The first question protects doctrinal precision.

The second generates institutional learning.

Both are necessary.

Galileo and slavery therefore should not be studied merely to determine whether they fall outside the formal definition of infallibility. Such analysis, while important, leaves untouched the mechanisms through which epistemic fracture became institutionally durable.

An institution serious about learning asks how future analogues might be recognized before centuries of hindsight make them obvious.

10. Dogmatic Definition and the Danger of Epistemic Closure

The preceding argument has implications for doctrinal development, though care is required.

Historical cases of ecclesial error cannot simply be projected onto dogmatic definitions. The Catholic doctrine of infallibility is explicitly designed to distinguish definitive teaching from the larger field of ecclesial judgment. Therefore, Galileo and slavery cannot function as direct counterexamples to formally defined infallible teaching.

Yet historical self-correction does raise a prior question concerning epistemic prudence before definitive closure.

The issue is not whether a dogma, once genuinely defined under conditions recognized by Catholic theology, should be treated as provisional. The more important question concerns the process through which the Church determines that a matter warrants irreversible definition in the first place.

Here epistemic humility becomes especially relevant.

10.1 The Asymmetry of Irreversible Claims

Not all theological claims carry equal consequences.

A provisional theological hypothesis may be reconsidered with relatively little institutional difficulty. A pastoral judgment can be revised. Disciplinary practices can change. Nondefinitive teachings can undergo development or clarification.

An irreversible dogmatic definition is different.

By definition, it seeks to remove a proposition from future doctrinal reversal.

This creates what may be called an epistemic asymmetry: the cost of premature closure is substantially greater than the cost of continued inquiry.

Where a matter has not yet been definitively settled, theological reflection can continue. Where a conclusion has been dogmatically closed, subsequent generations inherit not simply an argument but an authoritative boundary around permissible belief.

Such asymmetry generates a principle of doctrinal prudence:

The greater the irreversibility claimed for a theological judgment, the greater the evidentiary, historical, theological, and ecclesial warrant required before closure.

This is not skepticism.

It is proportionality.

The same principle operates elsewhere in rational decision-making. Decisions carrying irreversible consequences properly demand stronger justification than easily reversible ones.

Applied ecclesially, this principle suggests that dogmatic definition should ordinarily represent the culmination of profound convergence rather than the resolution of continuing ambiguity by institutional force.

10.2 Epistemic Closure and the Loss of Corrective Capacity

The concept of epistemic closure describes a condition in which a claim or interpretive framework becomes insulated from meaningful correction.

Closure is not always irrational. Some questions can reasonably be regarded as settled. Intellectual life would be impossible if every conclusion had to be reopened perpetually.

The problem arises when closure exceeds warrant.

Once a proposition becomes protected not merely by evidence but by institutional identity, corrective information may become increasingly difficult to integrate.

The Galileo affair demonstrates the danger in a non-dogmatic context. A cosmological interpretation became sufficiently entangled with biblical and ecclesiastical authority that empirical correction acquired theological consequences.

The lesson is not that doctrine should follow scientific fashion. It is that ecclesial authority should remain alert to occasions when contingent intellectual assumptions become embedded within theological certainty.

The slavery case reveals a similar pattern in moral life. Social arrangements can become so normalized that their theological justification appears self-evident. Once embedded in culture and institution, the inherited judgment may cease to be experienced as an interpretation at all.

Both cases therefore illustrate a fundamental danger:

historically contingent synthesis can masquerade as timeless necessity.

Epistemic humility exists partly to prevent that confusion.

10.3 Doctrinal Development Without Relativism

The strongest objection to this argument is predictable. If present teaching remains open to the possibility of future correction, does doctrinal confidence collapse into relativism?

It does not.

The objection assumes that only two epistemic positions exist: absolute certainty or relativistic uncertainty. CSR rejects this binary.

Human beings routinely possess rationally warranted beliefs without possessing exhaustive knowledge. Degrees of certainty can correspond to degrees of evidence. Some propositions may be exceptionally well grounded; others remain more contestable. Fallibilism concerns the condition of finite knowers, not the unreality of truth.

Lonergan’s cognitional theory is relevant here. Human knowing develops through attentiveness, intelligence, reasonable judgment, and responsible decision. Objectivity is achieved not by escaping subjectivity but by disciplined self-transcendence (Lonergan, 1972). The possibility of correction therefore belongs intrinsically to responsible knowing.

A similar insight can be applied to ecclesial development.

The Church need not choose between immobility and relativism.

It can recognize that fidelity sometimes requires deeper appropriation of truths already present within the tradition.

The history of slavery illustrates exactly this possibility. Christian anthropology did not need to abandon the imago Dei in order to condemn slavery. It needed to allow that principle to exercise a more radical judgment upon social practice.

Development, in such a case, represents increased coherence.

10.4 Tradition as Memory of Both Truth and Failure

Ecclesial tradition is often understood as the transmission of truth. It should also include the disciplined memory of failure.

A tradition that remembers only victories becomes epistemically dangerous.

Galileo should therefore remain in Catholic memory not principally as ammunition for anti-religious polemic but as a case study in the consequences of disciplinary overreach and hermeneutical rigidity.

Slavery should remain not merely as evidence of human sinfulness in general but as evidence that Christian communities can possess profound theological truths while failing to perceive their concrete moral demands.

Institutional memory of failure performs a protective function.

It weakens triumphalism.

It reminds present authorities that sincerity is not sufficient for correctness.

It demonstrates that majorities can be wrong.

It reveals that inherited consensus may contain blind spots.

And it teaches that critics who appear disruptive in one generation may sometimes become sources of correction in another.

Such memory does not require institutional self-contempt. Healthy humility differs from self-denigration. The purpose of remembering failure is not to cultivate permanent shame but to strengthen the conditions for future fidelity.

11. Ecclesial Epistemic Humility as a Theological Virtue

The preceding analysis permits a more precise definition of ecclesial epistemic humility.

Epistemic humility is not uncertainty about everything. Nor is it habitual self-doubt. It is the disciplined recognition that one’s access to truth is finite and that commitment to truth therefore requires openness to correction.

At the ecclesial level, epistemic humility can be defined as:

the institutional and theological disposition by which the Church affirms objective truth while recognizing the historical, interpretive, disciplinary, and moral limitations affecting its human apprehension and application of that truth.

This definition contains both confidence and restraint.

Confidence arises from realism: truth exists and may genuinely be known.

Restraint arises from fallibilism: finite knowers should not identify their every formulation with the fullness of reality.

Ecclesial epistemic humility therefore rejects two opposing pathologies.

The first is epistemic triumphalism: the assumption that ecclesial possession of revelation effectively eliminates the need for correction.

The second is epistemic relativism: the conclusion that historical development renders all claims merely contextual and therefore incapable of truth.

Humility occupies the disciplined space between them.

11.1 Humility Is Not Weakness

Institutions sometimes fear that acknowledging uncertainty will weaken authority.

The opposite may often be true.

Authority becomes fragile when it depends upon the appearance of perfect knowledge. Every discovered mistake then threatens legitimacy.

Authority grounded in accountable reasoning is more resilient. It can distinguish foundational commitments from contingent judgments and therefore revise the latter without destabilizing the former.

Papal apology illustrates this resilience.

John Paul II’s reconsideration of Galileo did not require abandoning Christianity. Leo XIV’s acknowledgment of the Church’s entanglement with slavery does not require repudiating Christian moral theology.

Both can instead be interpreted as acts of deeper conformity to principles the Church already regards as central.

Humility therefore does not oppose conviction.

It disciplines conviction.

11.2 The Christological Ground of Epistemic Humility

The case for ecclesial epistemic humility need not rest solely upon historical embarrassment. It possesses theological foundations.

Christian faith centers upon a God revealed in humility rather than domination. The Pauline hymn of Philippians 2 portrays Christ as refusing self-exaltation and assuming the condition of a servant. The epistemic implications should not be overstated, yet Christian authority modeled upon kenosis should be suspicious of institutional forms in which certainty functions primarily as an instrument of domination.

Jesus also repeatedly confronts religious confidence disconnected from moral perception. The Gospels portray religious authorities capable of knowing texts while failing to perceive persons standing before them. The problem is not absence of doctrine but misdirected interpretation.

This suggests that humility belongs not simply to philosophical fallibilism but to Christian discipleship.

The Church confesses truth as received, not manufactured.

What is received should not be treated as institutional possession in the proprietary sense.

Revelation judges the Church before the Church judges the world.

11.3 Humility and the Holy Spirit

A theology of epistemic humility must also address the doctrine of divine guidance.

Some may object that emphasizing ecclesial fallibility understates the role of the Holy Spirit.

But divine assistance need not be conceptualized as continuous suppression of human finitude.

Christian theology ordinarily does not understand grace as abolishing nature. Divine guidance may operate through historical processes of discernment, confrontation, repentance, scholarship, dialogue, testimony, and reform.

Indeed, the capacity for self-correction may itself be interpreted pneumatologically.

The Spirit’s guidance need not mean that error never occurs.

It may also mean that the Church is never permitted to make peace permanently with error.

This formulation provides a more historically credible account of providential guidance. The Spirit may work not only through ecclesiastical pronouncements but through the voices that challenge them, through scientific discovery, through victims of injustice, through theological criticism, through councils, through reform movements, and through the painful recognition that inherited judgments require revision.

Such an account does not democratize truth into preference.

It expands the possible instruments through which truth becomes ecclesially visible.

12. Toward a Corrective Ecclesiology

The combined lessons of Galileo, slavery, doctrinal development, and papal apology suggest the need for what may be called a corrective ecclesiology.

Corrective ecclesiology does not define the Church primarily through its errors. Rather, it understands the capacity for correction as one manifestation of ecclesial fidelity.

This approach asks a question too rarely foregrounded in discussions of authority:

What structures help a truth-oriented institution discover when it is wrong?

That question should matter enormously to a Church aware of its own history.

12.1 Institutional Correctability

Correctability must be more than an abstract possibility. It requires institutional practices.

These include rigorous historical scholarship, genuine interdisciplinary consultation, protection for responsible theological inquiry, mechanisms for hearing marginalized communities, clear differentiation among levels of magisterial authority, and willingness to revisit nondefinitive judgments when evidence warrants reconsideration.

None of these practices abolishes hierarchy.

They make hierarchy more epistemically responsible.

An institution that hears only confirmation of its existing judgments is structurally vulnerable to epistemic fracture.

12.2 The Role of Dissent

The question of dissent is especially sensitive.

Not all dissent is insightful. Dissent may arise from ideology, self-interest, intellectual fashion, or simple error. A Church need not romanticize disagreement.

Yet neither should disagreement automatically be interpreted as disloyalty.

History demonstrates that critical voices can sometimes identify truths institutions resist.

The proper response is therefore neither automatic suppression nor automatic celebration but disciplined discernment.

A mature ecclesial epistemology should be able to distinguish dissent that rejects the community’s foundational commitments from criticism that seeks their more faithful application.

This distinction is especially important in moral development.

Abolitionist Christians did not necessarily oppose Christianity by opposing Christian slaveholding. They could argue that Christian society had failed to live according to its own deepest principles.

Similarly, contemporary criticism may sometimes function internally rather than externally.

12.3 Victims as Epistemic Witnesses

The slavery case also requires renewed attention to the epistemic importance of victims.

Those who suffer under institutions often know dimensions of those institutions unavailable to those who govern them.

This does not confer automatic moral infallibility upon victims. It does create a reason for epistemic priority in listening.

A Church deliberating about moral questions affecting vulnerable populations should therefore regard their testimony not merely as pastoral information but as potentially relevant evidence.

The point is especially important where social distance is large.

Authority without exposure to consequences is vulnerable to abstraction.

Victim testimony reconnects moral reasoning with lived reality.

12.4 Science, Theology, and Reciprocal Humility

The Galileo case, meanwhile, suggests a model of reciprocal disciplinary humility.

Theology should avoid making empirical claims unsupported by appropriate evidence.

Science should avoid converting methodological naturalism into metaphysical naturalism without philosophical argument.

Psychology should not assume that measurable behavior exhausts personhood.

Economics should not reduce human flourishing to utility.

Political theory should not treat power as the sole explanatory category.

No discipline deserves epistemic imperialism.

CSRM therefore interprets interdisciplinarity not as optional academic decoration but as a safeguard against fracture. Reality is multidimensional, and responsible inquiry must remain open to correction across epistemic domains.

This is especially important for theology because its claims concern the whole of reality while its methods do not independently generate all forms of relevant knowledge.

Theology therefore requires conversation without surrender.

That is the intellectual posture Galileo should continue to teach.

13. Discussion: What Papal Apologies Reveal About Ecclesial Knowing

The analysis thus far suggests that papal apologies have greater theological significance than is sometimes acknowledged. They are commonly interpreted pastorally, as gestures of reconciliation, or morally, as acknowledgments of institutional wrongdoing. Both interpretations are legitimate. Yet they remain incomplete if the cognitive structure of repentance is ignored.

To apologize for a past ecclesial judgment or practice is implicitly to acknowledge that the earlier community did not apprehend some aspect of reality adequately. In this respect, apology is inseparable from epistemology. The Church does not merely say that contemporary sensibilities differ from those of previous centuries. It judges that an earlier judgment, practice, accommodation, or failure did not correspond sufficiently to what ought to have been recognized.

Leo XIV’s treatment of slavery makes this point unusually clear. Rather than resolving historical difficulty by insisting upon perfect continuity at the level of explicit moral judgment, Magnifica Humanitas acknowledges development in the Church’s understanding. Leo XIV (2026) recognizes both the perennial Christian affirmation of human dignity and the historical delay in perceiving slavery’s incompatibility with that dignity. This formulation is theologically important because it locates development neither in the creation of a new moral truth nor simply in changing social circumstances, but in the Church’s understanding of truths it already safeguarded.

The epistemological implications are substantial.

If the dignity of enslaved persons was real before Christians adequately understood its consequences, then reality exceeded ecclesial apprehension. If revelation contained anthropological principles whose implications emerged only gradually, then possession of revelation did not entail exhaustive understanding of revelation. And if an ecclesial community could sincerely preserve true principles while failing adequately to integrate them into moral judgment, then fidelity to revelation requires an ongoing process of intellectual and moral conversion.

The same structure is visible in the Galileo affair. The physical universe did not change when heliocentrism became ecclesiastically acceptable. What changed was the adequacy with which available knowledge, biblical interpretation, and theological authority were integrated. John Paul II’s (1992) reconsideration therefore acknowledged not a change in physical reality but a failure of interpretation and disciplinary judgment.

The two cases differ significantly, yet they converge upon one fundamental proposition:

The Church can be in possession of truth while remaining historically capable of misunderstanding dimensions, implications, or applications of that truth.

This proposition should be regarded not as an attack upon Catholic theology but as a necessary implication of Christian anthropology.

The Church is composed of finite human beings. Grace does not abolish finitude. Revelation does not automatically confer scientific expertise, perfect historical understanding, freedom from cultural prejudice, or exhaustive moral perception. Divine assistance cannot coherently be interpreted as eliminating every condition of human knowing when ecclesial history itself demonstrates otherwise.

13.1 From Epistemic Fracture to Epistemic Humility

The concept of epistemic fracture helps explain why such failures can coexist with sincere commitment to truth. Human beings do not ordinarily err because they consciously choose falsehood over reality. More often, error arises because partial truths are absolutized, relevant evidence is excluded, interpretations become invisible as interpretations, institutional interests distort judgment, disciplinary boundaries collapse, or socially marginalized experience remains outside the dominant field of perception.

Galileo and slavery illustrate different configurations of this phenomenon.

In Galileo, inherited cosmology, biblical interpretation, disciplinary boundaries, and ecclesiastical authority became intertwined. The failure occurred partly because the provisional character of one component of that synthesis was inadequately recognized.

In slavery, theological anthropology, biblical texts, social hierarchy, economic interest, colonial structures, racial categorization, and the experiences of enslaved persons were inadequately synthesized. Christianity could affirm universal dignity abstractly while tolerating practices contradicting that dignity concretely.

Epistemic fracture is therefore not simply ignorance. It is often failure of integration.

This insight clarifies the relationship between Critical Synthetic Realism and ecclesial epistemology. CSR does not ask the Church to weaken its commitment to objective truth. It asks the Church to distinguish more carefully between truth and historically situated acts of knowing. The more seriously objective truth is taken, the more necessary this distinction becomes. If reality exceeds interpretation, no institution may simply identify its present understanding with reality in its fullness (Asongu, 2026a).

Epistemic humility follows.

Humility here is not timidity about truth. It is disciplined resistance to the temptation to confuse confidence with omniscience. It permits the believer to say simultaneously: This is true and my understanding of this truth may not exhaust everything that truth entails.

For ecclesiastical institutions, the second proposition may be as important as the first.

13.2 The Question Future Generations May Ask

The most uncomfortable implication of papal apologies concerns the present.

Historical repentance is comparatively easy once consensus has shifted. Few contemporary Catholics feel personally threatened by acknowledging serious mistakes in the Galileo affair. Likewise, repudiating slavery no longer requires substantial moral courage within contemporary Catholic discourse.

The real test of epistemic humility is whether lessons drawn from past error alter present practices of knowing.

It is tempting to treat previous generations as uniquely blinded by their historical circumstances while imagining that contemporary Christians have achieved superior moral clarity. Such confidence merely reproduces the epistemic structure under criticism.

Every generation inhabits intellectual and moral environments that make some truths easier to perceive and others more difficult. Contemporary societies possess forms of knowledge unavailable to earlier generations, but they also possess their own economic interests, ideological formations, technological structures, political polarizations, anthropological assumptions, and cultural blind spots.

The appropriate question is therefore unsettling but necessary:

What are Christians presently defending, tolerating, ignoring, or failing to perceive for which future generations may wonder how a Church committed to human dignity could have been so slow to understand?

No responsible epistemology can answer this question with certainty in advance. If the blind spot were already completely visible, it would no longer function as a blind spot. What can be changed, however, are the institutional and intellectual conditions under which error is detected.

That is why ecclesial epistemic humility must move beyond personal virtue and become institutional practice.

14. Recommendations: Toward an Ecclesial Culture of Epistemic Humility

The historical cases examined here suggest several principles for ecclesial discernment. These should not be understood as procedural guarantees against error. No institutional arrangement can eliminate human fallibility. They are better understood as practices that increase ecclesial correctability.

14.1 Distinguish More Carefully Between Revelation and Interpretation

The Galileo affair remains paradigmatic because an interpretation of Scripture became entangled with the authority attributed to Scripture itself. The distinction between revelation and interpretation must therefore remain explicit.

This does not imply that revelation can be accessed without interpretation. Rather, it means that the authority of the object interpreted should not automatically be transferred to every interpretation of it.

Dei Verbum itself recognizes both the divine character of Scripture and the necessity of attending carefully to literary forms, historical circumstances, authorial intention, and the living tradition of the Church (Second Vatican Council, 1965). The interpretive task therefore belongs within fidelity rather than outside it. The Council’s theology of revelation provides substantial resources for precisely the kind of historically conscious hermeneutics required by epistemic humility.

14.2 Make Degrees of Ecclesial Certainty More Transparent

Catholic theology already distinguishes among dogmatic definitions, definitive teachings, authoritative but nondefinitive judgments, disciplinary decisions, theological opinions, and prudential applications (Sullivan, 2002). In practice, however, these distinctions may become blurred.

Greater transparency regarding the epistemic status of ecclesial statements would benefit both authority and reception.

The Church need not speak with the same degree of certainty about every question.

Where evidence remains developing, theological language should reflect that reality. Where conclusions are prudential, they should not acquire the rhetorical appearance of dogma. Where teaching is regarded as definitive, the grounds for such definitiveness should be correspondingly substantial.

This is not dilution of authority.

It is precision in authority.

14.3 Apply a Principle of Proportionality Before Irreversible Definition

The argument of this article supports a further principle:

The stronger and more irreversible the ecclesial claim, the greater the epistemic warrant that should precede its definition.

Historical experience counsels against premature closure. This is particularly important where biblical evidence is disputed, historical attestation is ambiguous, theological traditions remain plural, or the proposed definition extends significantly beyond what revelation clearly warrants.

The relevance of this principle extends beyond any single disputed dogma. It concerns the epistemic culture of doctrinal definition itself.

The doctrine of papal infallibility, properly understood, is narrow. Pastor Aeternus specifies conditions under which a pontifical definition possesses infallibility rather than treating papal speech generally as incapable of error (First Vatican Council, 1870). Precisely because definitive teaching claims exceptional authority, its use should reflect exceptional prudence.

Epistemic humility therefore does not require repudiating dogma. It requires caution about converting theological conclusions into irreversible dogmatic boundaries before the relevant warrant has reached proportional strength.

14.4 Institutionalize Interdisciplinary Correctives

Galileo demonstrates the dangers arising when theology attempts to settle empirical matters without adequate disciplinary competence.

The contemporary Church encounters questions involving neuroscience, artificial intelligence, genetics, climate science, economics, psychology, sociology, sexuality, medicine, and emerging technologies. Theological anthropology legitimately bears upon such questions, but theology cannot substitute for the technical knowledge required to understand them.

An ecclesial culture of epistemic humility should therefore normalize genuine interdisciplinary consultation before major judgments are made.

Consultation must also be genuinely critical. Experts should not be assembled merely to confirm conclusions already reached. CSRM requires reciprocal correction among disciplines rather than decorative interdisciplinarity.

14.5 Give Epistemic Weight to the Experience of Those Most Affected

The history of slavery demonstrates that those benefiting from an institution may perceive it differently from those suffering under it.

Consequently, moral discernment should include the testimony of persons most directly affected by the practices under consideration.

This recommendation should not be confused with the proposition that experience automatically determines moral truth. Experience must itself be interpreted critically. Nevertheless, excluding relevant experience impoverishes the evidentiary basis of moral reasoning.

Listening therefore has epistemic as well as pastoral significance.

The preferential attention Christianity gives to the marginalized may consequently possess a dimension insufficiently emphasized in theological epistemology: people at the margins can reveal features of social reality obscured from the center.

14.6 Protect Responsible Theological Inquiry

Correctability requires space in which alternative interpretations can be examined before institutional error becomes entrenched.

This does not imply unrestricted doctrinal individualism. Theologians remain accountable to evidence, argument, Scripture, tradition, ecclesial communion, and intellectual integrity. Yet excessive suspicion toward theological questioning can create conditions hostile to correction.

Newman’s theory of development itself emerged from recognition that theological understanding grows historically rather than remaining verbally static (Newman, 1845/1989). Congar’s theology of reform similarly demonstrates that critical reflection may arise from profound fidelity to the Church rather than opposition to it (Congar, 2011).

A mature ecclesial culture should therefore distinguish dissent aimed at dismantling the tradition from criticism seeking its greater coherence.

14.7 Make Institutional Memory of Failure Part of Formation

Galileo and slavery should not appear in Catholic education merely as apologetic problems requiring institutional defense.

They should be studied as cases in ecclesial epistemology.

Seminary formation, theological education, episcopal preparation, and Catholic universities could use historical failures to examine the mechanisms through which sincere communities become epistemically distorted.

An institution incapable of studying its failures honestly becomes vulnerable to repeating their structure even when the content changes.

Institutional memory therefore serves fidelity.

14.8 Understand Apology as the Beginning Rather Than the End of Correction

Finally, apology should not be treated as the terminus of institutional repentance.

An apology that does not alter epistemic practices risks becoming ceremonial.

The important question after saying “we were wrong” is:

What have we learned about how we became wrong?

Galileo teaches something about disciplinary authority, interpretive rigidity, and institutional enforcement.

Slavery teaches something about moral blindness, privilege, cultural normalization, economic interest, selective biblical interpretation, and failure to listen adequately to those experiencing domination.

Unless these mechanisms are identified, repentance remains incomplete.

15. Limitations and Directions for Further Research

Several limitations of the present study should be acknowledged.

First, Galileo and slavery are unusually prominent historical cases and cannot represent the full complexity of ecclesial development. Each contains extensive internal debates that exceed the scope of this article. Future studies should examine additional examples in which ecclesial teaching or practice has developed significantly, including religious liberty, usury, relations with Judaism, coercion in matters of conscience, capital punishment, and particular developments in biblical interpretation.

Second, papal apologies do not constitute a uniform theological genre. Different popes have employed different formulations of repentance, memory, purification, and institutional responsibility. A fuller theology of papal apology would require systematic comparison among texts across several pontificates.

Third, the relationship among indefectibility, infallibility, doctrinal development, and corrigibility requires more sustained dogmatic analysis than can be provided here. The present argument intentionally stops short of claiming that historical ecclesial error directly falsifies the Catholic doctrine of infallibility. A separate study could examine whether an epistemology of humility requires reconceptualization of the theological relationship among definitive and nondefinitive teachings.

Fourth, the concept of epistemic fracture requires further empirical and comparative development. The present study applies the concept primarily at the philosophical and theological levels. Future research could examine how institutional epistemic fracture operates sociologically through group conformity, organizational incentives, authority structures, information filtering, and mechanisms of exclusion.

Finally, the study has concentrated on Catholic Christianity. The underlying problem is considerably wider. Protestant, Orthodox, Jewish, Muslim, and other religious traditions possess their own histories of reinterpretation, institutional judgment, moral development, and retrospective correction. Comparative analysis may reveal that epistemic humility constitutes a broader virtue of religious knowing rather than a problem peculiar to Catholic ecclesiology.

16. Conclusion: A Church Humble Before the Truth

The question motivating this article was deceptively simple: What does it mean when the Church says, “We were wrong”?

The answer reaches beyond apology.

It means that ecclesial history contains moments in which later generations recognize that earlier judgments did not adequately apprehend reality. Galileo demonstrates how theological interpretation and ecclesiastical authority can overreach their epistemic competence. Slavery demonstrates how a religious community may possess profound truths concerning human dignity while failing, sometimes for centuries, to recognize fully what those truths demand.

Neither case proves that revelation is unreliable. Neither establishes relativism. Neither, taken by itself, disproves the Catholic doctrines of indefectibility or narrowly defined papal infallibility.

They establish something both more modest and more consequential:

religious possession of truth does not abolish the finitude of the religious knower.

Critical Synthetic Realism provides a framework for holding together two propositions frequently separated in contemporary thought. Reality is objectively real and truth genuinely matters; yet human apprehension of reality remains historically situated, partial, and vulnerable to epistemic fracture (Asongu, 2026a). Fallibilism need not result in relativism because correction presupposes a reality against which competing judgments may be evaluated.

Applied ecclesiologically, this distinction permits the Church to affirm truth without confusing itself with the fullness of truth.

The article has therefore proposed a distinction between ecclesial indefectibility and ecclesial epistemic impeccability. Catholic theology may affirm the first without pretending to possess the second. A Church sustained in its fundamental mission by divine grace remains a Church composed of finite interpreters capable of cultural blindness, disciplinary overreach, moral compartmentalization, institutional self-interest, and erroneous judgment.

Recognizing this reality need not weaken ecclesial authority.

It can purify it.

An authority that cannot admit error becomes dependent upon institutional self-defense. An authority capable of correction demonstrates that its ultimate allegiance lies beyond itself.

This is why papal apology can be understood as an act of institutional metanoia. The Church turns again toward a truth that exceeds its previous understanding. Repentance becomes epistemological as well as moral: not merely “we acted wrongly,” but also “we failed to see adequately.”

Leo XIV’s reflection on slavery makes this dynamic especially visible. The Church’s perennial affirmation of human dignity eventually generated a more complete recognition that slavery contradicted what Christianity already claimed about the person (Leo XIV, 2026). Development therefore need not mean that truth changed. It may mean that the Church became more answerable to the truth it already confessed.

The implication for contemporary ecclesial life is unavoidable.

A Church that remembers Galileo should be cautious when theological authority enters domains requiring other forms of expertise.

A Church that remembers slavery should be cautious when inherited social arrangements are treated as though their familiarity guaranteed their morality.

A Church that has apologized for past failures should recognize that future repentance remains possible.

And a Church capable of future repentance should cultivate humility before making present judgments irreversible.

This is not an invitation to perpetual hesitation. Faith requires conviction. Moral life requires judgment. Ecclesial authority sometimes requires decisions.

But conviction is not omniscience.

The deepest form of ecclesial confidence may therefore consist not in believing that the Church can never be corrected, but in trusting that fidelity to truth includes the courage to undergo correction.

Papal apologies reveal that ecclesial repentance and ecclesial authority need not be enemies. The capacity to say “we were wrong” may itself become evidence of a community still being called beyond itself toward the truth.

Critical Synthetic Realism thus proposes neither skepticism nor theological surrender. It proposes a Church realist about truth, fallibilist about human apprehension, synthetic in its pursuit of knowledge, courageous in judgment, and humble enough to remain corrigible.

For a Church that confesses that Truth ultimately transcends every human formulation, epistemic humility should not be experienced as a concession to modernity.

It should be recognized as fidelity.
