Terminology — the word field
Sin is not one concept but a semantic cluster. Mapping the vocabulary is what prevents the doctrine from flattening into "moral failure."
Hebrew
| Term | Root idea |
|---|---|
| chatta't / chata' | Missing the mark; failing an objective |
| pesha' | Rebellion; breach of covenant against a suzerain |
| 'awon | Crookedness, iniquity — carries both guilt and its consequence |
| ra' | Evil, badness, harm |
| rasha' | Wickedness; guilt in the forensic sense |
| shagag | Inadvertent error, straying |
| ma'al | Treachery, unfaithfulness — especially against holy things |
Greek
| Term | Root idea |
|---|---|
| hamartia | Missing the mark; in Paul often a personified power, not merely an act |
| parabasis | Overstepping a known boundary — requires a law to transgress |
| paraptoma | Trespass, false step, lapse |
| anomia | Lawlessness (1 Jn 3:4) |
| asebeia | Ungodliness — sin Godward before it is manward |
| adikia | Unrighteousness, injustice — sin manward |
| opheilema | Debt (Matt 6:12) |
| epithymia | Desire, — disputed whether sin itself or only its tinder |
Hamartia in Romans 5–7 functions as a reigning power with agency: it enters, reigns, deceives, kills. Any hamartiology that treats sin only as discrete acts cannot account for Paul's grammar — and will produce a soteriology of forgiveness without deliverance.
Origin of sin
Three tiers, in order:
- Angelic / pre-human fall. Isa 14:12–15 and Ezek 28:12–17 (both contested as to referent), Jn 8:44, 1 Tim 3:6, 2 Pet 2:4, Jude 6, Rev 12:9.
- Human fall. Gen 3 — Adam's transgression as covenantal breach, not a dietary infraction.
- Ongoing propagation. Every subsequent human person.
The unanswerable question: how does a sinless will in a sinless environment produce a sinful choice? Augustine's answer is : the will turns from a greater good to a lesser, and the cause is a defect, not a positive efficient cause.
Sin is finally irrational — it has no sufficient reason. That is a feature, not a gap. Give sin a rational cause and you make it necessary; make it necessary and you have made God its author.
The essence of sin
These are not mutually exclusive. But each tradition ranks them differently, and the ranking drives everything downstream.
| Definition | Core claim | Associated with |
|---|---|---|
| Lawlessness | Want of conformity to, or violation of, God's law (WSC 14) | Reformed, confessional Protestant |
| Privation of good | — sin has no substance; it is corrupted good | Augustine, Aquinas |
| Unbelief | The root sin is failure to trust God's word and character | Luther |
| Pride | Self-exaltation; the creature's refusal of creaturehood | Augustine, R. Niebuhr |
| Idolatry | Disordered worship; exchanging Creator for creature (Rom 1:23,25) | Biblical-theological |
| Disordered love | — right loves ranked wrongly | Augustine, Luther |
| Concupiscence | Disordered desire, prior to any act of will | Trent (as tinder) / Reformed (as sin) |
| Relational rupture | Broken covenant and personal betrayal, not rule-breaking | Relational, covenantal |
| Structural evil | Sin embedded in institutions, powers, arrangements | Liberation theologies, Wink |
Press any definition with one question: does it explain sin Godward first? Ps 51:4 ("against You, You only") and asebeia preceding adikia in Rom 1:18 both push the vertical to primacy. Definitions that begin horizontally end in ethics without theology.
Original sin — the core battleground
Two distinguishable things travel under one name. Positions differ on whether one, both, or neither transmits.
- Original guilt () — legal liability for Adam's sin.
- Original corruption () — the inherited moral condition.
| Position | Guilt imputed? | Nature corrupted? | Mechanism | Result |
|---|---|---|---|---|
| Pelagian | No | No | Adam as bad example | Sin by imitation; grace unnecessary in principle |
| Semi-Pelagian | No | Weakened only | Wounded will | Man initiates, grace assists |
| Arminian | No | Yes — total depravity | Inherited corruption + prevenient grace | Depravity real, universally counteracted |
| Wesleyan | Cancelled universally by the atonement | Yes | Corruption + prevenient grace | Ability restored to all |
| Roman Catholic | Yes — loss of original justice | Yes, but concupiscence not formally sin | Loss of the | Baptism removes guilt; concupiscence remains as tinder |
| Eastern Orthodox | Generally no | Yes — mortality and corruption | — we inherit death, and sin from fear of it | Sin as disease more than debt |
| Reformed (federal) | Yes | Yes | Immediate imputation via covenant headship | Guilt and corruption both, immediately |
| Reformed (realist) | Yes | Yes | Seminal identity — we were in Adam (cf. Heb 7:9–10) | Guilt because we actually sinned in him |
| Placean (mediate) | Derivatively | Yes | Corruption inherited first; guilt imputed because corrupt | Guilt follows corruption |
Traducianism vs. creationism (origin of the soul) intersects here. Traducianism explains transmission easily; creationism explains it with difficulty but avoids dividing the soul.
eph' ho pantes hemarton. Render it "because all sinned" (personal acts) and you tend Arminian or Orthodox. Render it "in whom all sinned" (Vulgate in quo) and you tend realist. Read it as "death spread because all sinned — in Adam, representatively" and you get federalism.
The structural stake: if Adam's sin is not imputed, the parallel logic of Christ's imputed righteousness weakens with it. Rom 5:12–21 is one argument, not two. This is the single verse on which the most doctrine hangs.
Depravity and its effects
Total depravity is extensive, not intensive. Sin affects every faculty; it does not make every person maximally evil, nor destroy the imago Dei.
By faculty
- Noetic — the mind's suppression of truth (Rom 1:18,21; 1 Cor 2:14; 2 Cor 4:4; Eph 4:17–18). This is where hamartiology feeds apologetics: presuppositionalism is an epistemology built on the noetic effects of sin.
- Volitional — bondage of the will. Not loss of voluntariness but loss of liberty: the sinner freely wills according to a nature that will not choose God. Cf. Edwards on .
- Affectional — disordered loves; enmity toward God (Rom 8:7).
- Relational and social — violence, exploitation, alienation.
- Cosmic — creation subjected to futility (Rom 8:20–22).
Total inability is inability to do anything savingly pleasing to God apart from grace. Distinguish it from the capacity for civic good, which common grace preserves (Gen 20:6; Rom 2:14–15).
Collapse total inability into "unbelievers can do no good at all" and your doctrine cannot account for the observable decency of unbelievers — at which point the hearer discards the whole doctrine rather than the overstatement. Precision here is not pedantry; it is what keeps the doctrine survivable in public.
Imago Dei after the fall — defaced (majority Protestant), lost as to likeness but retained as to image (patristic/Catholic), or effectively destroyed (some Lutheran). Gen 9:6 and Jas 3:9 constrain how far "destroyed" can be pushed.
Taxonomy of actual sin
- Commission / omission — Jas 4:17
- Presumptuous / inadvertent — Num 15:22–31; Ps 19:12–13
- Secret / open
- Sin against knowledge — degrees of culpability: Lk 12:47–48; Jn 9:41; 15:22
- Mortal / venial — Catholic (grave matter + full knowledge + deliberate consent). Reformed rejects the ontological category but affirms degrees of heinousness (WLC 150–151)
- Sin unto death — 1 Jn 5:16–17, referent disputed
- Blasphemy against the Spirit — Mk 3:28–30: settled attribution of the Spirit's work to Satan, not a repeatable isolated act
- Apostasy — Heb 6:4–6; 10:26–31, the warning-passage debate
Corporate and structural sin
Solidarity in guilt: Achan (Josh 7), Daniel's confession (Dan 9), the "sin of the world" (Jn 1:29), the archai and stoicheia of Eph 6:12 and Col 2:15.
Is "structural sin" a genuine theological category, or a metaphor for aggregated personal sin? Both overclaiming and dismissing distort — overclaim and culpability evaporates into systems; dismiss and Scripture's corporate confessions become unintelligible.
Sin and the law
Four Pauline functions:
- Reveals sin — knowledge of sin comes through the law (Rom 3:20; 7:7)
- Provokes sin — the law occasions rebellion (Rom 7:8–11)
- Reckons sin — sin exists without law but is not counted the same way (Rom 5:13)
- Condemns, and drives to Christ (Gal 3:19–24)
Sin precedes law — death reigned from Adam to Moses. Law is therefore not the ground of sin's existence, only of its formal reckoning. This is precisely why a purely legal definition of sin cannot stand alone.
Consequences of sin
| Category | Content |
|---|---|
| Guilt (reatus) | Objective liability to punishment — forensic, not felt |
| Pollution (macula) | Moral defilement of nature |
| Death | Physical, spiritual (Eph 2:1), eternal (Rev 20:14) |
| Wrath | Settled, holy opposition — judicial disposition, not passion (Rom 1:18) |
| Alienation | From God, self, neighbour, creation — the four ruptures of Gen 3 |
| Bondage | To sin (Jn 8:34), Satan (Eph 2:2), death (Heb 2:14–15) |
| Judicial hardening | God gives over — Rom 1:24,26,28; Ex 9:12; Rom 9:18 |
| Cosmic curse | Ground cursed, creation groaning — Gen 3:17–19; Rom 8:20–22 |
Distinguish guilt from guilt feelings, and shame from guilt. Most contemporary pastoral confusion comes from collapsing these. Honour–shame and guilt cultures read the same texts asymmetrically, and both registers are in Scripture (Gen 2:25; 3:7,10).
Sin in the believer
The most pastorally consequential section. Does the believer still have a sin nature?
| Model | Claim | Reading of Rom 6–7 | Weakness |
|---|---|---|---|
| Two natures | The old nature remains intact alongside a new nature; the believer is a battleground between two entities | Rom 7 = normal Christian experience of two natures | Ontological dualism inside one person; obscures who "I" am; can excuse sin as "not really me" |
| One renewed person | One person, definitively renewed, with remaining corruption — not a second self | Rom 6 = definitive break; Rom 7 = the renewed man's conflict with indwelling sin | Must avoid implying sin is peripheral or easily conquered |
Related disputes
- Rom 7:14–25 — regenerate or unregenerate "I"? (Later Augustine and the Reformed: regenerate. Much patristic and modern scholarship: pre-Christian or rhetorical ego.)
- Definitive vs. progressive sanctification — "already dead to sin" (Rom 6) against "put to death" (Col 3:5).
- Perfectionism — Wesleyan entire sanctification, Keswick "victorious life," and the Reformed rejection of both. Test each against 1 Jn 1:8–10.
Trent: the inclination remains in the baptized but "is not truly and properly sin." Reformed and Lutheran: disordered desire is sin even unconsented — which is why Rom 7:7 makes coveting the test case.
This single disagreement generates most of the Catholic–Protestant divergence on assurance, confession, and perfection. It is a smaller-looking question than imputation and nearly as load-bearing.
God's relation to sin
The hardest section. Handle with precision or not at all.
- God is not the author of sin — WCF 3.1; Jas 1:13; 1 Jn 1:5. Non-negotiable boundary.
- Yet sin is not outside His decree — Acts 2:23; 4:27–28; Gen 50:20.
Mechanisms proposed
Permissive decree · primary and secondary causation (God ordains the act as event, the creature supplies the moral quality) · · Molinist middle knowledge · Arminian simple foreknowledge · open theism's denial of exhaustive foreknowledge.
Theodicies
Free-will defence (Plantinga) · soul-making (Hick, Irenaean) · greater-good and felix culpa · skeptical theism · cruciform theodicy.
Related: supralapsarian vs. infralapsarian ordering of the decrees — where the fall sits relative to election.
The confessional language is deliberately apophatic: "yet so as thereby neither is God the author of sin." It asserts two truths and refuses to resolve the mechanism.
Systems that fully resolve the tension almost always do so by quietly sacrificing either divine sovereignty or divine holiness. Naming a mystery is not a failure of rigour. Pretending to have dissolved it is.
Christ and sin
- Sinlessness — 2 Cor 5:21; Heb 4:15; 1 Pet 2:22. Universally affirmed.
- Impeccability vs. peccability — non posse peccare (unable to sin, given the hypostatic union) against posse non peccare (able not to sin, preserving genuine temptation).
The three registers of the atonement
A useful completeness test for any atonement theory:
- Guilt → penal substitution, satisfaction, justification
- Power → Christus Victor, union with Christ, regeneration
- Pollution and presence → sacrificial cleansing, sanctification, glorification
Does impeccability empty Heb 4:15 of force? If Christ could not have sinned, in what sense was he tempted as we are?
And: a theory that answers only one of the three registers leaves the doctrine of sin unanswered. Most popular atonement preaching answers guilt only — which is exactly why so many believers are forgiven and still enslaved.
Contemporary pressure points
- Historical Adam and evolutionary biology — monogenism vs. polygenism; whether original sin survives without a historical fall (Schneider, Enns vs. Madueme, Reeves, Collins). The most consequential live front: positions taken here silently rewrite the whole of §04.
- Therapeutic reduction — sin recategorised as brokenness, trauma, or dysfunction. Contains real insight — sin does enslave, and the Orthodox disease model has ancient warrant — but collapses if culpability disappears. Test: can your account still say guilty?
- Liberation and structural readings — sin as systemic injustice. Test: can your account still say personal?
- Psychology, compulsion and addiction — diminished responsibility. Degrees of culpability were always in the tradition (Num 15; Lk 12:47–48), so this is not a novel problem, only a sharpened one.
- Creation care — sin against creation as a category.
Each of these pressures is applied by people who have noticed something true. The weak response is to treat the insight as an attack. The strong response is to absorb the insight and refuse the reduction — which requires knowing exactly which load-bearing claim you cannot give up.
Locate your framework
Four decisions determine nearly everything else. Answer them and the rest follows almost mechanically — most people absorb a hamartiology by tradition without ever locating themselves on these axes, then discover their soteriology contradicts their anthropology.
Is Adam's guilt imputed, or only his corruption inherited?
Is fallen inability moral or natural — and is it universally relieved?
Is disordered desire itself sin, or only its consent?
Is a historical fall necessary to the doctrine?
Answer the four decisions above. The readout names where your answers converge, what they commit you to, and — more usefully — where they strain against each other.
