Original Sin

Overview

Original sin is the Christian doctrine that locates humanity’s fundamental fallen condition in Adam’s transgression. It describes human beings as alienated from God, subject to death, inclined toward disordered desire, and unable to heal themselves apart from divine grace. While its biblical roots lie in Genesis, Psalm 51, and especially Paul’s Adam–Christ typology, the doctrine has been shaped by diverse theological traditions that focus differently on inherited guilt, corruption of the will, mortality, and the need for prevenient or regenerating grace. Across these traditions Christ—“the last Adam”—is presented as the decisive remedy through incarnation, cross, resurrection, and the gift of the Spirit.

Biblical shape

The biblical shape of the doctrine moves from a good creation to a decisive rupture, a spreading bondage to sin, and finally to liberation in Christ.

• Creation: Humanity is made in God’s image and placed in embodied, relational life (Genesis 1–2). Evil is not intrinsic to creation.
• Transgression: Genesis 3 narrates disobedience, shame, and alienation; readers later interpret this event as the root of the fallen condition.
• Judgment and mortality: Genesis 3:16–24 links sin with exile, toil, pain, and death; Paul reads human death and sin in relation to Adam (Romans 5; 1 Corinthians 15).
• Universal spread: The Old Testament and New Testament portray sin as pervasive in society and the human heart (Genesis 4; Psalm 14; Romans 3).
• Torah and conscience: The law reveals and restrains sin but does not abolish its power (Exodus 20; Romans 7–8).
• Christ as remedy: New Testament typology casts Christ as the corrective headship to Adam’s, bringing righteousness, life, and new creation (Romans 5; 1 Corinthians 15; Philippians 2).
• New creation: Resurrection, the Spirit, and the promises of Revelation inaugurate liberation from corruption and death (Romans 6–8; 1 Corinthians 15; Revelation 21).

This pattern yields language of sin (ḥaṭṭāʾt, hamartia), transgression (paraptōma), disobedience (parakoē), corruption (phthora), and death (thanatos) that the New Testament develops into theological claims about human solidarity with Adam and with Christ.

• Ephesians 2:1–3 — the depiction of humanity as “dead in trespasses and sins” and under the sway of passions.
• Romans 7:14–25 — the experience of the law revealing and intensifying human struggle with sin.
• Romans 8:20–23 — creation’s subjection to corruption and the hope for liberation in the new creation.

Theological significance

Original sin functions as an interpretive key for the Bible’s story of creation, fall, and new creation. It explains why mortality, social brokenness, and moral weakness affect all human beings and why divine intervention, not mere moral exhortation, is presented as necessary. The doctrine has been handled differently within Christian traditions:

• Western (Augustinian) trajectories often emphasize inherited guilt and a pervasive corruption of the will, arguing that prevenient and justifying grace are necessary for moral restoration.
• Eastern (Orthodox) discourse frequently prefers the term ancestral sin, highlighting mortality and the corruption that is passed down without the same juridical language of transmitted guilt.
• Roman Catholic theology historically frames original sin
