Penance & Confession (the forgiveness of post-baptismal sin)

What does the church do with a Christian who sins after baptism? The first answer was uncertain — some taught there was no second repentance at all. From that starting point the tradition developed in stages: a single, once-only "second repentance" (the Shepherd of Hermas); a public, graded, once-in-a-lifetime discipline of exomologesis and the orders of penitents (Tertullian, Cyprian, Nicaea, Basil), with a rigorist revolt denying the gravest sinners any return at all (the Montanist Tertullian, Novatian); then the quiet revolution of the Irish penitentials, which made confession private, tariffed, and — decisively — repeatable; its universalization as mandatory annual confession (Fourth Lateran Council, 1215); its scholastic systematization, with matter, form ("I absolve thee"), parts, and minister all fixed (Thomas Aquinas); and its dogmatic definition as a sacrament, with contrition, confession, and satisfaction and a judicial absolution, at the Council of Trent (1551), against a Reformation that kept confession but denied it was a sacrament of satisfaction.

Timeline

The Shepherd of Hermas (c. 150)

The Shepherd of Hermas reports the rigorist teaching that baptism is the only repentance there is, and confirms it as "sound doctrine" — then softens it: for those already baptized the Lord has appointed one further repentance, but "he has opportunity to repent but once," for "there is but one repentance to the servants of God."¹

Tertullian (c. 203 and c. 217)

Tertullian, as a churchman, gives the classic account of this "second repentance" — the "plank" for the shipwrecked sinner — and of its outward rite, exomologesis: confession, sackcloth and ashes, fasting, and prostration before the presbyters and the congregation.² Later, as a Montanist, he reversed course: attacking a bishop's edict that forgave adultery and fornication, he divided sins into the remissible and the irremissible, denying the church any power over the graver kind.³

Callistus of Rome (c. 217)

Callistus, bishop of Rome, is the earliest bishop we can name exercising the power Tertullian denies: the edict Tertullian mocks — "the bishop of bishops… I remit… the sins both of adultery and of fornication" — is most often assigned to him, and his rival Hippolytus independently attacks the same laxity, complaining that Callistus reconciled the sexually sinful ("all had their sins forgiven by himself") and defended a mixed church — wheat and tares, the ark of clean and unclean — that holds sinners within it rather than expelling them.⁴

Cyprian of Carthage (c. 251)

After the Decian persecution left the church full of the lapsed, Cyprian set the mediating course: even those who only bought certificates (the libellatici) have sinned and must repent, and peace is not to be seized on the strength of martyrs' letters but granted by the bishop — yet the penitent, even the adulterer, is truly offered reconciliation, for to deny repentance its "fruit" only drives the fallen to despair.⁵ He records that Novatian himself had once endorsed peace for the dying lapsed.⁶

Novatian (c. 251)

Novatian, the rigorist pole, led a schism holding that the church cannot reconcile the lapsed — "as if there was no longer for them a hope of salvation, not even if they should do all things pertaining to a genuine and pure conversion"; his followers called themselves the Cathari, "the pure," and a Roman synod of sixty bishops condemned the position and reaffirmed healing the fallen "with the medicines of repentance."⁷

The Council of Nicaea (325)

The Council of Nicaea hardened the mediating discipline into church-wide law: the lapsed pass through graded orders of penitents — hearers, then prostrators, then those who stand with the faithful "but without oblation" — for fixed terms of years before full communion; and, against Novatian, no one at the point of death "must be deprived of the last and most indispensable Viaticum."⁸

Basil of Caesarea (c. 375)

Basil's canonical letters turned the graded system into a detailed penitential code, assigning each sin a fixed term distributed across the four orders — weepers, hearers, kneelers, and standers — the intentional murderer, for instance, drawing a full twenty years (four weeping, four hearing, seven kneeling, four standing) before the sacrament is restored.⁹

Pacian of Barcelona (c. 380)

Pacian, bishop of Barcelona, answered a Novatianist named Sympronian in three Letters and a treatise, the Paraenesis ad Paenitentiam — the Latin West’s sustained reply to the rigorists then flourishing in Spain. The Novatian case, he reports, “amounts to this… That there is no room for repentance after Baptism; that the Church cannot remit mortal sin; that by the receiving of sinners she herself perishes” — and he answers that the power to bind and loose was not the Apostles’ alone but passed to their successors the bishops, so that “whether we baptize, whether we constrain to penance, or grant pardon to the penitent, we do this by the authority of Christ,” a power from which Christ, in the terms of the grant, “excepted nothing whatever… great or small.”¹⁰

Ambrose of Milan (c. 384)

Ambrose, writing his two books Concerning Repentance directly against the rigorist heirs of Novatian, is the Latin voice for the church’s power to reconcile even the gravest sinner: appealing to the keys and to Christ’s word “whosesoever sins ye forgive they are forgiven” (John 20:22–23), he holds that “when the Lord forgave all sins, He made an exception of none” and “granted to His priests the power of loosing without any exception” — the graver the sin, the heavier the penance, but the door is never shut — and reads the prodigal son, restored by his father to robe, ring, and feast, as the very pattern of the reconciled penitent.¹¹

The Irish Penitentials (c. 525–650)

The Irish and Welsh monastic handbooks — Finnian, Columbanus, and Cummean — quietly reversed the ancient discipline: confession became private ("sins are to be absolved in secret"), each sin drew a fixed "tariff" of bread-and-water fasting graded to deed and rank, and, unlike the once-only public penance, it could be repeated — "there is no impediment to the iteration of penance."¹² Carried to the Continent and to England by the Celtic and Anglo-Saxon missions, this form displaced the public discipline it could not otherwise be replaced.¹³

The Fourth Lateran Council (1215)

The Fourth Lateran Council made the now-universal private confession universal law: Canon 21, Omnis utriusque sexus, requires every Christian of "both sexes" past the age of discretion to "confess all their sins at least once a year to their own (parish) priest" and communicate at Easter, on pain of excommunication and denial of Christian burial — and in the same canon binds the priest to the seal of confession, never to "make known the sinner."¹⁴

Thomas Aquinas (c. 1274)

With private, repeatable confession now the universal law of the Latin church, Thomas Aquinas supplied its scholastic architecture — the framework the Council of Trent would later define almost point for point. Penance is a true sacrament, in which "the priest, by his deed and word … signifies the work of God Who forgives his sins"; its matter is the acts of the penitent (with sin the "remote matter… for detestation, and destruction"); its parts are contrition, confession, and satisfaction; its minister is a priest alone, wielding the "key of ministry"; and confessing every mortal sin to that priest is "necessary for the salvation of a man who has fallen into a mortal actual sin." Decisively, he defends the indicative form — the sacrament "consists… in the removal of a certain matter, viz. sin… expressed by the priest saying: 'I absolve thee'" — the judicial Latin absolution the Greek East never adopted and the Reformers would reject.¹⁵

The Council of Trent (1551)

Against the Reformers — who retained confession but denied it was a sacrament of satisfaction and read priestly absolution as a mere announcement of the gospel — the Council of Trent (Session 14) defined penance as a true sacrament instituted by Christ for sins after baptism (the "second plank after shipwreck"), whose parts are contrition, confession, and satisfaction, and whose absolution "is not a bare ministry only… but is after the manner of a judicial act, whereby sentence is pronounced by the priest as by a judge."¹⁶

Arguments

Related arguments — the power of the keys

The words on which the whole sacrament is built — “whose soever sins ye remit, they are remitted … whose soever sins ye retain, they are retained” (John 20:23), “whatsoever thou shalt bind … loose” (Matthew 16:19; 18:18) — confer some authority over sins. But what kind? Two readings, each independently advocated with its own proof-texts, divide the confessions and are best read together: does the minister’s absolution effect the forgiveness (God ratifying his sentence over a particular penitent), or only declare a forgiveness God gives directly to faith through the gospel? Weighed adversarially on their own pages.

Does priestly absolution effect forgiveness? (the judicial / instrumental reading) — contested

The reading the Council of Trent defines — absolution “is not a bare ministry only … but is after the manner of a judicial act, whereby sentence is pronounced by the priest as by a judge” — and, in a broader form, the near-universal pre-Reformation consensus (East and West): the keys confer a real, heaven-ratified power to remit and retain, so the minister is an instrument of forgiveness, not a herald. Strong on the natural sense of a two-way discretionary grant and the weight of patristic witness (Chrysostom’s “God ratifies above,” Ambrose, Cyril); but Trent’s sharp juridical-sentence form is a Latin scholastic development the Greek East never took (its absolution stays deprecative), a discernment-reading strand in the fathers (Jerome on Matthew 16:19; Gregory) does not require it, and the Greek of John 20:23 does not force effect over declaration. Disputed between the confessions, no clear winner (contested).

Is priestly absolution a declaration of the gospel? (the declarative reading) — plausible

The Reformers’ reading (Luther, Calvin): the minister does not himself confer forgiveness but, as an ambassador bound to the word, declares and applies the pardon God gives directly to faith. Coherent and genuinely grounded — the perfect-passive verbs of John 20:23 make God the agent, “God alone forgives” (Mark 2:7), and a real patristic minority (Jerome’s leprosy analogy on Matthew 16:19; Gregory; Origen) reads the keys as discernment. But it is short of probable: the grammar its proponents lean on does not decide the question (Mantey’s future-perfect overstates it; Cadbury’s caution is the corrective), the retain clause fits a conferred discretion better than a general proclamation, and the patristic majority runs toward a heaven-ratified power that is more than announcement. Coherent, not ruled out, short of majority (plausible).

Related arguments — attrition and contrition

Trent’s sacrament requires the penitent’s contrition, but how much sorrow is enough? A scholastic dispute the timeline never settles divides on it: does perfect contrition — sorrow out of love of God — have to be present for the sacrament to forgive, or does attrition — imperfect sorrow, from fear of hell or the shamefulness of sin — suffice when joined to sacramental absolution? Trent Session 14, ch. 4 blesses attrition as a genuine, dispositive sorrow without fully closing the question, and in 1667 Alexander VII forbade either school to censure the other — two independently advocated readings, best read together, weighed adversarially on their own pages.

Does attrition (fear-born sorrow) suffice with the sacrament? (the attritionist reading) — contested

The Scotist/nominalist line, and the closest thing to Trent’s own lean: attrition joined to sacramental absolution truly reconciles — the sacrament confers grace ex opere operato on a penitent who places no obstacle, so no distinct act of love is required. Strong by the letter of Session 14 (attrition “disposes him to obtain the grace of God in the sacrament”), by Canon 5’s defence of attrition as “a true and profitable sorrow,” and as the more common scholastic view; but Trent pointedly declined to define that no beginning of love is needed, and the contritionist objection that pure servile fear is not real conversion was left standing by Rome in 1667. Genuinely disputed, no clear winner (contested).

Is heartfelt contrition (love of God) required for the sacrament to forgive? (the contritionist reading) — plausible

The Thomist line (in its measured form) and the Jansenist line (in its strong form): some act of love of God is required, so that the merely attrite penitent must, in the sacrament, become contrite (ex attrito fit contritus); fear-born sorrow alone does not justify. Coherent and grounded — justification is by charity (Trent, Session 6), and Aquinas locates forgiveness at the term, when attrition is “quickened by grace,” not at its fear-born origin — and permitted by Rome. But short of probable: the attritionist reading was the more common view and sits closer to Session 14’s letter, and the hard Jansenist form collides with Canon 5. Coherent, not ruled out, short of majority (plausible).

Was there an original rigorism, later relaxed?

One sub-claim runs across the whole early half of the timeline rather than sitting at any point on it: not "who was strict and who was lenient," but the historical question of whether the pre-Nicene church ever held it had the power to reconcile the gravest sins — apostasy, murder, adultery/fornication — or whether an original rigorist discipline that permanently excluded such sinners was only later loosened. It is weighed adversarially on its own page, with an assessment of the reading it serves.

• Did the early church deny it could reconcile the gravest sins? (an original rigorism, later relaxed) — contested (the tightening-then-loosening curve is sound and near-consensus; the strong claim that the church uniformly denied the power, only inventing it later, is weak against Hermas and Dionysius of Corinth).
