Origin Patristic; formulated by the Greek fathers from the fourth century and restated for a modern readership in twentieth century Orthodox theology.

Eastern Orthodox theology describes sin in medical rather than forensic terms, and the difference is structural rather than a softening of the same account. A juridical model asks what penalty a sin incurs and how the debt is discharged. A therapeutic model asks what damage the sin has done and how the damage is repaired. Christ is the physician, the Church is a hospital, and salvation is a healing that ends in theosis, the participation of the human being in the divine life. The difference begins with what is inherited. The Greek fathers held that what passes from Adam is mortality and corruption, together with a will weakened and disordered, rather than guilt. The Latin tradition after Augustine read Paul's letter to the Romans as saying that all sinned in Adam, a reading the Greek text does not obviously carry, and built inherited guilt upon it. Orthodoxy speaks instead of ancestral sin, and the consequence is that an infant is baptised into the healing of a damaged nature rather than acquitted of an inherited charge. The disease itself is the passions, the pathe: settled dispositions in which desire, anger and thought have gone out of their proper order. The ascetic literature gathered in the Philokalia is clinical writing about them, offering diagnosis, prognosis and treatment, with watchfulness, prayer, fasting and obedience as the therapy and the spiritual father as the physician who applies it. Confession within this frame is not primarily the discharge of a penalty. The penitent stands before an icon of Christ, and the priest is a witness and a physician rather than a judge whose sentence settles the matter. Where a penance is given it is understood as medicine proportioned to the illness rather than as a punishment proportioned to the offence.

Meaning in the Attesting Source

Ancestral sin (propatorikon hamartema) names what is inherited as mortality and corruption together with a weakened will, and not as inherited guilt. 2

John Meyendorff's Byzantine Theology: Historical Trends and Doctrinal Themes (Fordham University Press, 1979) sets out two readings of the same patristic evidence on ancestral sin, propatorikon hamartema, which names what is inherited as mortality and corruption together with a weakened will, and not as inherited guilt. Meyendorff's own reading, built from close study of the Greek fathers' commentary on Romans 5:12, holds they read the verse as because all sinned and never taught inherited guilt, and that the Latin rendering in whom all sinned is what made inherited guilt possible in the West. The opposing reading, examining the same Greek patristic corpus, holds the contrast is drawn too sharply, that Greek writers also speak of inherited culpability in places, and that the divergence is more a modern polemical construction than a patristic fact.

Position Profile

Opposing Position

This framing is commonly contrasted with Western juridical models of sin and atonement, including penal substitution, which Orthodox writers often criticise as importing a courtroom logic foreign to the Greek patristic tradition. 2

The Claim

Orthodox theology often frames sin less as a legal transgression incurring guilt and more as a sickness or wound of human nature, so that salvation is understood therapeutically, as healing, rather than primarily as acquittal from a verdict. 1

Open Questions

Point in Dispute

Twentieth century Orthodox theology drew a strong contrast between Greek and Latin readings of inherited guilt, resting a great deal of it on a single clause of Romans 5:12. Other scholars hold the difference overdrawn, and that Greek writers do at times speak of an inherited culpability. Both positions are held now.

No systematic survey of the Greek patristic corpus for language of inherited culpability, conducted independently of the Romans 5:12 reading and with the Latin material read on the same terms and by the same criteria, has been carried out.

Origins

Held By

Eastern Orthodox Christianity 1

Origin Period

Patristic; formulated by the Greek fathers from the fourth century and restated for a modern readership in twentieth century Orthodox theology. 2

Origin of the Name

The vocabulary is medical: therapeia, healing; nosos, sickness; pathos, which is at once a passion and an affliction. 3

Attestation

Earliest Attestation

The account of the eight thoughts written by Evagrius Ponticus in fourth century Egypt, from which the Western list of capital sins descends by way of John Cassian and Gregory the Great. 4

Structure

Sin as sickness, the passions (pathe) as the disease, Christ as physician, the Church as hospital, and a healing that ends in theosis. 1

Structure

The ascetic literature gathered in the Philokalia treats the passions clinically, with watchfulness, prayer, fasting and obedience as the therapy and the spiritual father as the physician who applies it. 5

Physician, Hospital, Patient

Ask a juridical theology what sin is and the answer will be framed by penalty: what is owed, who pays, on what ground the debt is remitted. Ask Orthodox theology and the frame is medical. Sin is a sickness, the human being is a patient, Christ is the physician and the Church is a hospital. The two models are not gentle and harsh versions of one account; they ask different questions and get different answers, and much of what looks like Orthodox reticence about Western doctrines of atonement is simply the second frame declining the first frame's question.

The disease has a name in this literature. It is the passions, the pathe, and the word means both a passion and an affliction, something suffered as much as something done. A passion in this sense is not an emotion but a settled disposition in which desire, anger or thought has gone out of its proper order and now runs the person rather than being lived by them. The ascetic writings gathered in the Philokalia are clinical literature about exactly this: how each condition presents, what it is likely to do next, what treats it, and in what order.

The therapy is correspondingly practical. Watchfulness over the movements of one's own mind, continual prayer, fasting, obedience and the repetition of a short invocation are the standing prescriptions, and the spiritual father is the physician who applies them to a particular case rather than a judge who sentences it.

Confession sits inside this. The penitent stands before an icon of Christ, and the priest is present as witness and as physician; where a penance is given it is understood as medicine proportioned to the illness, not as punishment proportioned to the offence. And the end of the treatment is not acquittal but theosis, the participation of the human being in the life of God, which the fathers put as the claim that God became human so that the human might become divine.

Ancestral Sin and the Eight Thoughts

The divergence starts with what is inherited from Adam. The Greek fathers held that what passes down is mortality and corruption, a nature damaged and a will weakened, and Orthodoxy therefore speaks of ancestral sin rather than original sin. Guilt is not inherited on this account, because guilt attaches to acts and a newborn has committed none. Baptism is accordingly read as entry into the healing of a damaged nature rather than as acquittal on a charge already filed.

Much of the argument turns on a single clause of Paul's letter to the Romans. The Greek can be read as saying that death spread to all because all sinned. The Latin rendering made it in whom all sinned, which points the sentence at Adam and gives inherited guilt a foothold that the Greek does not obviously offer. Twentieth century Orthodox theology, Meyendorff in particular, built a good deal on that difference.

The atlas carries the point as debated rather than settled, because the second position is also held: that the contrast has been drawn far too sharply, that Greek writers do at times speak of an inherited culpability, and that a good part of the East and West divide here is a modern polemical construction rather than a patristic fact.

The same literature produced something the Western tradition made famous. Evagrius Ponticus, writing in fourth century Egypt, listed eight thoughts, the logismoi, that assault a monk: gluttony, fornication, love of money, dejection, anger, listlessness, vainglory and pride. John Cassian carried the list to the Latin West and Gregory the Great reworked it in the sixth century, and out of that reworking the familiar seven eventually settled, with vainglory absorbed into pride and envy added.

In their original setting they are not sins. They are thoughts, arriving unbidden, to be noticed and treated. Nobody confesses a thought in Evagrius; a monk learns to recognise which one has come and what answers it. That is why the East never turned the list into a schedule of offences, and the West did.
