Why it matters for reading Scripture
The doctrine of sin, studied as part of humanity. The reading of Genesis 3 depends on it.
Systematic theologyWhat does it teach as a whole?
Hamartiology is the part of Christian theology that studies sin: what it is, where it came from, how it reaches every human being, what it does to people and to the world, and how it is overcome. It sits between the doctrines of humanity and salvation, and in Catholic teaching it is shared between dogmatic and moral theology.
Study v1.1, 14 October 2026
The doctrine of sin, studied as part of humanity. The reading of Genesis 3 depends on it.
Inherited guilt resolves into four questions; the first two, a damaged human condition and mortality, are affirmed almost universally.
Traditions divide on whether Adam's act is counted to his descendants: Reformed and 1689 Baptist confessions affirm it; Orthodox, Church of the East and Adventist sources deny it.
Holds that the ancestral sin was personal to Adam and Eve and that their descendants inherit its consequences, foremost death, rather than its guilt.
Orthodox writers describe the Greek patristic view as an inheritance of mortality rather than sinfulness, with sinfulness following from mortality; unbaptized infants are not held guilty, and there is no limbo. The tradition is not uniform: the Confession of Dositheus of 1672 speaks of hereditary sin flowing to Adam's posterity and of infants needing baptism for its remission, while still distinguishing that inheritance from the sins of personal choice. The Immaculate Conception is not accepted.
A family of communions whose sources differ.
The Coptic Orthodox teaching of Pope Shenouda III holds that the sentence of death came to every person from Adam because all were in Adam's loins, while Ethiopian Orthodox scholarship reads the church's classic texts as rejecting guilt inherited from Adam. The Armenian Church rejects the Immaculate Conception yet teaches that Mary was cleansed of original sin when the Holy Spirit came upon her, and a Syriac Orthodox source says the same.
Follows Theodore of Mopsuestia: through Adam humanity inherits mortality and a tendency to sin, not guilt, and children are baptized for adoption rather than remission.
It venerates Mary as "Mother of Christ our God and Saviour", a title the Catholic Church recognized as legitimate in 1994; what it does not teach is the Immaculate Conception.
Holds that all are implicated in Adam's sin, which is transmitted by propagation and is contracted, not committed: a deprivation of original holiness and justice that does not have the character of a personal fault in his descendants.
Human nature is wounded, not totally corrupted. Sins are graded as mortal and venial; for infants who die unbaptized there are grounds for hope, not certainty; and the Immaculate Conception was defined in 1854.
The Lutheran confessions teach that original sin is truly sin and condemns those not born again through baptism and the Spirit, while holding that it is an accident and not the substance of human nature.
The Augsburg Confession of 1530 teaches that all born naturally after Adam are born without fear of God and trust in him and with concupiscence, and Melanchthon's Apology endorses the ancient definition of original sin as the absence of original righteousness.
The Reformed confessions teach that the guilt of Adam's sin is imputed and his corrupted nature conveyed, so that fallen humanity has wholly lost all ability of will to any spiritual good accompanying salvation.
Federal theology treats Adam as the covenant head of humanity, grounding the immediate imputation of his guilt. Some sins are held more heinous than others, and the Canons of Dort address the salvation of believers' children who die in infancy; elect infants are held to be saved.
Article IX of the Thirty-nine Articles calls original sin the fault and corruption of the nature of every person, which deserves God's wrath.
Infant baptism is kept.
Speaks of a sinful nature but does not teach that Adam's act is imputed to infants, who are held safe until they are accountable; no list of grades of sin is given.
Earlier, the Anabaptists denied the validity of infant baptism.
Baptists are divided: the Second London Confession of 1689 affirms imputed guilt and speaks of elect infants dying in infancy, while the Traditional Statement of 2012 denies that any person is guilty before personal sin, and the Baptist Faith and Message of 2000 is written to allow both.
Many hold that all infants who die are saved.
The Wesleyan tradition distinguishes sin properly so called, a voluntary transgression of a known law, from involuntary transgressions that still need Christ's atoning blood.
The Church of the Nazarene calls original sin an inherited propensity to actual sin for which no one is accountable until its divinely provided remedy is neglected or rejected, and teaches entire sanctification as a work of God after regeneration, distinguishing a pure heart from a mature character. Wesley himself said that sinless perfection was a phrase he never used.
Teaches that humanity fell by voluntary transgression and so incurred physical and spiritual death; its statement does not define inherited guilt.
It teaches progressive sanctification.
Its statement says that Adam's descendants share his fallen nature and are born with weaknesses and tendencies to evil, without the language of inherited guilt, and it states no condemnation of infants who die.
Hold that people are born sinless and do not inherit Adam's sin, and that infants are innocent and safe.
Teach that sin and imperfection are inherited from Adam, with mortality, and that inherited sin is answered by the ransom.
Blasphemy against the spirit is held unforgivable; there is no infant baptism, and perfection lies in the future.
The Second Article of Faith holds that people will be punished for their own sins and not for Adam's transgression, while the tradition affirms that the Fall brought physical and spiritual death.
Children are alive in Christ until the age of eight.
Reuven Hammer describes human beings as born neither carrying nor tainted by the sins of their ancestors, and sin as chet, a going astray.
Rabbinic Judaism developed the doctrine of the two inclinations, the good and the evil yetzer, and the Jewish Encyclopedia reports that the majority of the rabbis did not hold Adam responsible for the sins of humankind and that Jewish theology admits no unpardonable sin. The Day of Atonement atones for sins against God, but wrongs against a neighbor must first be put right.
The Qur'an teaches that God accepted Adam's repentance and that no soul bears the burden of another, and children are born in fitrah.
Hammudah Abdulati describes sin as deliberate defiance of God's law, acquired, not inborn, and graded as major and minor; shirk is unforgiven if unrepented. The remedy is repentance, tawbah, and wrongs to people need their pardon.
The Book of the Watchers, 1 Enoch 6 to 16, expands Genesis 6:1 to 4: two hundred Watchers led by Shemihazah take human wives and father giants, and Asael teaches forbidden arts. It places the origin of evil in a superhuman rebellion beside the Adamic account of Genesis 3, and is usually dated to the third century before Christ or earlier.60616263
Two works written after the fall of the Temple answer the Adam question differently: Fourth Ezra laments that the fall was not Adam's alone but that of his descendants also, while Second Baruch replies that each of us has been the Adam of his own soul. Both are later than Paul's letters.6465
The Origenist teaching of a fall of minds before the world is condemned under Justinian around 543, and the Second Council of Constantinople in 553 names Origen among the heretics in its eleventh anathema. Whether the fifteen anathemas against Origen printed with its acts were the council's own work remains disputed.7273
The Fourth Lateran Council requires all the faithful who have reached the age of discretion to confess all their sins at least once a year to their own priest.74
The Council of Trent's Decree on Original Sin holds that Adam's sin passes by propagation, not imitation, and is removed by Christ's merit in baptism, and that concupiscence remains in the baptized but is not truly and properly sin. The decree states that it does not mean to include the Virgin Mary.77
John Taylor of Norwich denies inherited guilt in The Scripture Doctrine of Original Sin (1740). John Wesley answers him in The Doctrine of Original Sin (1757), and Jonathan Edwards in Original Sin (1758), arguing that the universal fact of sinful acts points to a sinful predisposition and that God constitutes humanity one with Adam.838485
Humani generis allows that the evolution of the body may be studied but holds that polygenism is not open to the faithful, because original sin proceeds from a sin committed by an individual Adam.88
Original Sin and the Fall: Five Views sets out the current systematic positions side by side: Augustinian-Reformed (Hans Madueme), moderate Reformed (Oliver Crisp), Wesleyan (Joel Green), Eastern Orthodox (Andrew Louth) and reconceived (Tatha Wiley).93
Begin with the biblical vocabulary: the Bible has no single word for sin, and its main Hebrew and Greek terms each carry their own picture; concordances group the words differently and give different counts102103.
Read the terms in their contexts rather than by etymology alone, and do not read the later rabbinic grading of chet, 'avon and pesha' back into every biblical use52.
Weigh the key texts, above all Romans 5:12, where the Greek eph' hō has been read as in whom, because, and with the result that all sinned; each reading supports a different account of how Adam's sin reaches his descendants104105106.
Read the Jewish writings of the Second Temple period and after as witnesses to how the question was argued, keeping apart those, such as 4 Ezra and 2 Baruch, that are later than Paul's letters6465.
Trace the doctrine through the Fathers, councils and confessions, settling disputed dates against the sources6610768.
Separate the four questions often joined as inherited guilt: whether a damaged condition passes, whether mortality passes, whether Adam's act is imputed, and whether his descendants are personally blameworthy for it13211.
Describe each tradition from its own confessional or official documents, and where a confession does not address a question, say so rather than infer a position for the whole tradition.
Compare Judaism and Islam in their own categories, which are not those of the Christian debate5055.

No. What is usually called inherited guilt is four separate questions: whether a damaged condition passes from Adam, whether mortality passes, whether Adam's own act is counted to his descendants, and whether they are personally blameworthy for it. Almost every Christian tradition affirms the first two. They divide on the third, which the Reformed and 1689 Baptist confessions affirm and the Orthodox, Church of the East, Adventist, Restorationist and Latter-day Saint sources deny, and almost none affirm the fourth1317211113947.
Mark 3:28 to 29 speaks of blasphemy against the Holy Spirit117. Catholic teaching describes it as the deliberate refusal of God's mercy157, Anglican and Methodist articles hold that not every deliberate sin after baptism is unpardonable158, and the Jewish Encyclopedia reports that Jewish theology admits no unpardonable sin52.
This is the liveliest current debate. Population genetics points to a population that did not fall below a few thousand rather than to a single pair: BioLogos speaks of thousands, and Dennis Venema of about 10,00098159. The positions run from a historical first pair to a purely symbolic reading9893. S. Joshua Swamidass argues that Adam and Eve could be genealogical ancestors of all people without being their only genetic ancestors160, while Humani generis (1950) held that polygenism is not open to the faithful88.
John Paul II held that sin in the proper sense is always a personal act, while allowing that sin may be called social in three analogical senses, and accepted structures of sin as always rooted in personal sin9291. Liberation theology holds that structures carry and multiply sin beyond any person's intention, and the Puebla conference of 1979 tied poverty and structural injustice to social sin101. The tension between these two positions runs through most later debate.
