Question 2: Whether the Doctrine of Original Sin Contradicts the Confucian View of Human Perfectibility?

Objection 1. It seems that the Catholic doctrine of original sin contradicts the Confucian affirmation of human perfectibility. Catholicism teaches that man, though created good, has fallen into a state of original sin, rendering him incapable of attaining perfection without supernatural grace (Catechism of the Catholic Church, §§404–405). Meanwhile, Mencius asserts: “All men have a mind which cannot bear to see the suffering of others” (Mencius 2A:6), which suggests that moral sensitivity is natural and universal. Hence, the Catholic doctrine seems pessimistic compared to Confucian optimism.

Objection 2. Korean Neo-Confucian thinkers like Yi I (Yulgok) developed a sophisticated understanding of the moral emotions (qi, 氣) as dynamically shaped by moral principle (li, 理). If moral disorder arises from the imbalance of qi, not from a metaphysical rupture, then the Catholic notion of a hereditary moral wound is incompatible with the Confucian system. As Yulgok says: “The heart is fundamentally good, but becomes disordered due to the turbulence of vital forces” (Seonghak Jipyo, vol. 1, p. 56).

Objection 3. Confucian thinkers never posited a universal and inherited guilt. Even Jeong Yakyong (Dasan), while highly critical of corruption and immorality, insisted that “man possesses the inner capacity for virtue from birth” (Collected Works of Dasan, vol. 4, p. 118). The Catholic idea of baptismal regeneration presupposes a fallen nature requiring healing by sacrament, whereas Confucian education relies on moral awakening and self-discipline. Thus, their anthropologies are fundamentally opposed.

On the Contrary, Aquinas holds that grace is not a contradiction of nature, but its healing and elevation: “Grace perfects nature” (ST I, Q.1, Art.8 ad 2). Similarly, Mencius insists that goodness is not simply natural impulse but a seed requiring cultivation. Hence, both traditions identify an order to be recovered—whether by grace or by ethical effort.

I Answer That, the apparent contradiction between original sin and Confucian perfectibility results from different diagnoses of moral disorder, not incompatible visions of moral destiny. Catholicism and Confucianism both affirm that the human being is called to perfection—teleios (τέλειος) in the Christian tradition (cf. Matthew 5:48) and cheng (誠, sincerity or authenticity) in the Confucian tradition—but differ on the origin and mechanism of failure.

In the Catholic view, as systematized by Augustine and Aquinas, human nature was wounded by a historical and hereditary rupture: original sin. It is not merely a lack of virtue or balance, but the absence of original justice and the presence of concupiscence (ST I-II, Q.82, Art.3). All human beings inherit this condition, and are incapable of restoring moral wholeness without grace. As Pieris notes, “Christian salvation history is a response to an ontological catastrophe: a rebellion that left no part of man unscathed” (An Asian Theology of Liberation, p. 37).

The Four–Seven Debate (사단칠정논변) between Yi Hwang (Toegye) and Yi I (Yulgok) provides one of the most refined articulations of Korean Neo-Confucian anthropology and its implicit soteriological structure. This debate, centered on the nature and origin of moral emotions (jeong, 情), reveals a profound internal dialectic on the relationship between human nature and ethical failure—precisely the terrain where Confucian and Catholic thought may fruitfully dialogue.

Toegye contended that the Four Beginnings (sa-dan, 四端)—compassion, shame, deference, and the sense of right and wrong—are immediate and pure manifestations of li (理), the metaphysical principle of order. Because li is universally embedded in human nature (seong, 性), these moral sentiments arise from a deep ontological alignment with Heaven (Cheon, 天). In this view, moral failure is accidental: it stems not from a flaw in li, but from the interference of disordered qi (vital force). This corresponds to the Catholic notion of natural law (lex naturalis) as the participation of human reason in the eternal law of God (ST I-II, Q.91, Art.2).

Yulgok, by contrast, argued that even the Four Beginnings cannot be isolated from qi. He proposed a more integrated vision in which all moral responses arise through qi, and therefore possess an affective, unstable, and embodied character. While still affirming the goodness of human nature, Yulgok emphasized the necessity of ongoing formation and correction through education, ritual, and disciplined attentiveness (gyeong, 敬). This nuanced view aligns with Thomistic anthropology, where the passions (passiones animae) are not evil in themselves but are morally ambiguous and in need of regulation by the rational soul, elevated by grace (ST I-II, Q.24, Art.3).

Thus, while Toegye’s position resonates with Augustinian-Platonic idealism, where moral perception reflects innate metaphysical clarity, Yulgok’s framework is more Aristotelian-Thomistic, recognizing that moral growth occurs through the embodied soul in a world of disorder. Importantly, Yulgok’s insistence on the qi-mediated nature of emotion anticipates the Catholic understanding of concupiscence—the tendency of the appetites to resist reason, even in the baptized.

Rather than viewing the Four–Seven Debate as a divergence from Catholic teaching, we may see it as a mirror of Catholic distinctions between nature and grace, intellect and will, reason and passion. Korean Neo-Confucianism, in this debate, offers a layered moral psychology that invites Catholic theology to deepen its own account of human complexity—without abandoning the dogma of original sin or the necessity of grace.

Reply to Objection 1.Mencius affirms moral seeds, but Catholicism critiques not the existence of moral inclinations but their efficacy in a wounded state. The lex naturalis remains post-Fall, but it cannot be fully obeyed without healing by grace (ST I-II, Q.109, Art.2).

Reply to Objection 2. Yulgok’s emphasis on turbulent qi closely mirrors the Catholic concept of disordered passions post-lapsum. Both traditions affirm that moral training must be embodied and attentive to disorder.

Reply to Objection 3. While Confucian education trusts in the teachability of virtue, Catholic theology maintains that no pedagogy alone can overcome the rupture of original sin. Dei Verbum (§10) insists on the necessity of divine revelation and sacramental mediation in addition to ethical instruction.

Conclusion: Although the two traditions diverge in their accounts of disorder, both affirm the dignity of moral transformation and the goal of ethical perfection. The doctrine of original sin names the ontological rupture Catholicism sees as requiring divine healing, while Confucianism presents a model of self-cultivation rooted in ontological continuity but shaped by psychological and cosmological discipline.

Observations : The Four–Seven Debate offers Catholic moral theology not merely an anthropological analogy, but a practical mirror for reflection. Through the tension between Toegye and Yulgok, we are invited to move beyond simple dichotomies—between grace and nature, intellect and passion, virtue and ritual—toward a non-dualistic model of the moral self. Toegye’s emphasis on the metaphysical purity of the Four Beginnings (sa-dan) echoes the Augustinian doctrine of natural illumination, where the moral law is inscribed directly in the intellect as a trace of the divine. In contrast, Yulgok’s assertion that moral emotions are always mediated through qi reveals a realistic psychology of the fallen human condition, closer to the Thomistic doctrine of concupiscence and the moral complexity of the passions.

What is especially fruitful for Catholic moral theology is the Confucian insistence—articulated most clearly by Yulgok and later echoed by modern Korean philosophers such as Kim Young-Ho—that moral growth cannot occur apart from embodied, ritualized attentiveness. In his analysis of Yulgok’s ethical philosophy, Kim argues that “qi is not simply a source of distortion, but the very medium through which ethical life takes place,” and thus requires continuous rectification rather than suppression (Human Nature and Moral Mind, Seoul National University Press, 2006).¹ This positions ritual and form not as secondary aids, but as necessary structures for moral transformation—a claim deeply consonant with Catholic liturgical theology.

From the Catholic side, Anselm Min has repeatedly emphasized that the integration of Confucian moral formation into Korean Catholicism has helped produce a form of Christianity that is neither voluntaristic nor antinomian. As he writes, “Korean Catholicism shows how the Confucian ideal of self-cultivation and the Catholic doctrine of grace can be mutually reinforcing when situated in a concrete historical tradition” (Korean Catholicism and Confucianism, p. 121).² Confucianism thus protects Catholic spirituality from devolving into either moral quietism or legalism by proposing a dynamic, disciplined vision of human moral agency.

Park Soon Kyung, a major voice in Korean Catholic thought, also warns against the over-psychologization of grace in post-conciliar Western Catholicism. In dialogue with Confucian ritual theory, she emphasizes that “salvation is not merely interior but enacted: the cultivation of virtue is itself part of divine pedagogy” (Ritual, Redemption, and the Korean Spirit, Catholic University of Korea, 1998).³ The Confucian stress on seong (誠, sincerity) as moral authenticity attained through social and bodily discipline resonates deeply with the Catholic doctrine of cooperation with grace, where human agency is not erased but elevated.

Finally, Byung-Chul Han’s philosophical diagnosis of the “ritual vacuum” of late modernity reinforces the urgent relevance of this Confucian insight. In The Disappearance of Rituals, Han writes: “Without forms, human life becomes flat and directionless. Ritual is the medium through which time is stabilized, and the self is morally shaped” (Polity Press, 2020, p. 42).⁴ The liturgical crisis in contemporary Catholicism—the desacralization of the Mass, the neglect of ascetical disciplines—mirrors Han’s critique. Recovering ritual as a formative, not merely expressive, act is a convergence point between the Confucian and Catholic traditions.

In this way, Korean Neo-Confucianism—through both its classical formulation and its modern interpreters—offers Catholic theology a renewed grammar of moral formation: one that integrates ritual, affect, effort, and metaphysical order. It proposes that to speak of salvation without formation, or grace without discipline, is to speak incompletely of the human vocation.
