Part II – The Nature of Sin


3. Philosophical and Theological Nature

3.1 Sin as Rebellion, Corruption and Privation

The essence of sin lies in the rejection of divine authority. Scripture defines it as lawlessness (anomia)—a deliberate refusal to submit to God’s rule (1 John 3:4). Sin is therefore not an external defect but an inward revolt of the will. Augustine (354–430 AD) described this rebellion as curvatus in se—the human being “curved in upon himself,” turning from the Creator to the creature (Augustine, 1998).

Philosophically, sin is not a substantive entity but a privation of good (privatio boni), the distortion of God’s perfect order. Evil possesses no independent existence; it is the lack of what ought to be (Aquinas, 1265–1274). Theologically, sin corrupts both intention and structure, producing disintegration within the self and within creation. Thus, “all have sinned and fall short of the glory of God” (Romans 3:23 NRSV): humanity’s failure is not partial but total in scope.

3.2 Sin as Condition and Act

Sin operates simultaneously as a condition of being and an act of doing. The condition denotes humanity’s fallen nature—an inherited tendency toward disobedience (Romans 5:12). The act denotes individual choices that actualise that condition (James 1:14–15). Barth (1932) differentiates between “sin in the singular,” describing the universal human state, and “sins in the plural,” the specific manifestations of that state.

This distinction clarifies the tension between responsibility and inevitability: though the sinner is enslaved by the power of sin, he remains morally accountable. Paul’s lament, “I do not do the good I want, but the evil I do not want is what I do” (Romans 7:19), reveals the paradox of bondage and guilt—the will divided against itself. Hence sin is both ontological (a fallen state) and ethical (personal transgression).

3.3 The Power and Dominion of Sin

Beyond individual acts, Scripture depicts sin as an enslaving power ruling over humanity. Paul personifies sin as a tyrant demanding obedience: “Let not sin therefore reign in your mortal body” (Romans 6:12). This language of domination suggests that sin exerts systemic and psychological control. The human being is not merely a wrongdoer but a captive requiring deliverance (John 8:34).

Reinhold Niebuhr (1941) describes sin’s dominion as “the universal self-contradiction of humanity”: the capacity for freedom misused to create bondage. The doctrine of total depravity in Reformation theology (Calvin, 1559) likewise stresses that every faculty—mind, emotion, and will—is affected. Thus, even noble deeds are tainted by self-interest apart from grace (Isaiah 64:6).

Sin’s dominion extends beyond the individual to social and cosmic dimensions: “The whole world lies under the power of the evil one” (1 John 5:19). It creates alienation—between God and humanity, among people, and between humanity and the created order. Only divine intervention through the Mediator can break this power (Romans 8:1–2).


4. The Origin of Sin

4.1 The Fall of Lucifer and the Birth of Corruption

The first appearance of sin occurs not in human history but in angelic rebellion. Isaiah 14:12–15 and Ezekiel 28:12–17 symbolically portray the pride of a celestial being who sought equality with God. This primordial act of self-exaltation introduced corruption into the spiritual realm (2 Peter 2:4). Pride, therefore, is the root of all sin—a will set against the Creator (Lewis, 1942).

4.2 The Fall of Humanity

Genesis 3 presents humanity’s fall as a moral and relational rupture. Tempted by the serpent, Adam and Eve distrusted God’s word, choosing autonomy over dependence. The consequence was immediate alienation: spiritual death, shame, and expulsion from Eden. Paul interprets this event as the entry of sin and death into human existence (Romans 5:12). In Adam all die; in Christ all may live (1 Corinthians 15:22).

The narrative reveals that sin is not ignorance but distrust—believing the lie that good can be attained apart from God. This disobedience fractured not only the human heart but also creation itself, producing toil, decay, and mortality (Genesis 3:17–19).

4.3 Transmission and Original Sin

The doctrine of original sin explains the continuity of sin’s condition throughout humanity. Augustine argued that Adam’s guilt and corruption are transmitted to all his descendants through natural generation (Confessions VII.21). Although later theologians debated its mechanism, Scripture affirms its universality: “There is no one righteous, not even one” (Romans 3:10).

Original sin does not abolish human freedom but renders it disordered: the will is free to choose, yet inclined toward evil (Aquinas, 1265–1274). Modern theology describes this as existential estrangement—a state into which every person is born and from which only divine grace can deliver (Tillich, 1957). Thus, the doctrine of sin begins not with human acts but with the inherited misalignment of the human condition itself.
