Topic IX

Indulgences

The practice that lit the Reformation's fuse.

On October 31, 1517, Martin Luther posted ninety-five theses questioning the sale of indulgences in Saxony. The Reformation began, in a sense, with this protest. Everything that followed — sola scriptura, sola fide, the rupture of Western Christendom — flowed downstream from a specific pastoral practice that Luther believed had gone badly wrong. The theology of indulgences is still probably the least understood doctrine in the Catholic tradition, because it is still consistently judged by the worst version of itself from five centuries ago.

The scandalous version — the one Luther attacked — was real. The theology behind it was more complex, and the Catholic Church itself has significantly reformed both the theology and the practice. Understanding where the dispute actually sits today requires distinguishing the abuse Luther condemned from the doctrine Rome still teaches.

Protestants have often been taught that indulgences are the sale of forgiveness, that Catholics believe they can buy their way out of hell, that the practice continues today in essentially the same corrupt form, and that the Catholic Church still runs a spiritual commerce in salvation.

Catholics have often been taught that Protestants reject any structure of penance and repair, that they cannot distinguish between forgiveness of sin and its ongoing consequences, and that their critique of indulgences is really a rejection of the Church's authority to bind and loose at all.

Neither holds up. Contemporary Catholic teaching is emphatic that indulgences cannot be bought, are not remission of sin's guilt (which comes only through Christ), cannot benefit someone in mortal sin, and function within — never apart from — the grace of Christ's atonement. Protestants do not reject penitential discipline in principle; they reject the specific theological machinery of indulgences as lacking scriptural warrant and historically prone to abuse.

What Catholics actually teach

Remission of Temporal Punishment

Catholic teaching defines an indulgence as the remission, before God, of the temporal punishment due to sins whose guilt has already been forgiven. It is not remission of sin itself. It is not sold. It is not a license to sin. It is an application to the individual believer of the Church's power, rooted in the treasury of Christ's merits and the merits of the saints, to remit the ongoing consequences of sin for which the penitent would otherwise need to make satisfaction.

The conditions for obtaining an indulgence are strictly spiritual: sacramental confession, eucharistic communion, prayer for the pope's intentions, and detachment from sin. No money is required. No money can be required.

What Protestants actually teach

No Warrant, No Machinery

Protestant traditions reject the entire structure of indulgences. The distinction between the guilt of sin (removed by Christ) and the temporal punishment of sin (requiring human satisfaction, remitted by the Church) is not recognized. The treasury of merits accumulated by Christ and the saints, drawn upon by papal authority, is not recognized. The Church's binding and loosing power, while real, does not extend to trading in the consequences of sin.

Luther's Ninety-Five Theses attacked the abuses directly; the Reformation confessions rejected the whole theology.

The Catechism gives the current official definition:

An indulgence is a remission before God of the temporal punishment due to sins whose guilt has already been forgiven, which the faithful Christian who is duly disposed gains under certain prescribed conditions through the action of the Church which, as the minister of redemption, dispenses and applies with authority the treasury of the satisfactions of Christ and the saints. Catechism of the Catholic Church § 1471, citing Paul VI, Indulgentiarum Doctrina

The theology rests on three claims Catholic teaching holds as distinct doctrines, each scriptural in principle. First, that sin produces not only guilt (fully remitted by Christ through the sacraments) but also temporal consequences that may require satisfaction or purification. Second, that Christ and the saints' merits constitute a "treasury" upon which the Church can draw in applying satisfaction. Third, that the Church, through the binding and loosing authority given to Peter and the apostles, has the power to dispense from this treasury on behalf of particular penitents.

Paul VI's 1967 apostolic constitution Indulgentiarum Doctrina substantially simplified and reformed the system. The mechanical counting of "days" (which had come to suggest time off purgatory in a literal sense) was abolished. Indulgences are now classified simply as partial or plenary. The conditions are thoroughly spiritual: a specified act of devotion, sacramental confession, communion, prayer for the pope's intentions, and freedom from attachment to sin. The money-payment system that sparked Luther's protest was condemned by Trent itself in 1562–63 and has been absolutely forbidden ever since.

Key scripture the Catholic tradition cites includes Matthew 16:19 and 18:18 (binding and loosing given to Peter and the Church), 2 Corinthians 2:10 (Paul writing that what he has forgiven is forgiven in the person of Christ), and the broader logic of ecclesial mediation throughout the New Testament.

Luther's Ninety-Five Theses (1517) are not a Protestant confession — they were written while Luther still considered himself a faithful Catholic seeking reform of a specific abuse. But they articulated objections that became foundational to the Reformation.

Any truly repentant Christian has a right to full remission of penalty and guilt, even without indulgence letters. Any true Christian, whether living or dead, participates in all the blessings of Christ and the Church; and this is granted him by God, even without indulgence letters. Luther, Ninety-Five Theses (Theses 36 and 37), 1517

The mature Reformation position broadened from attacking abuse to rejecting the entire theological structure. The Augsburg Confession does not treat indulgences as a distinct topic but implies their rejection in its teaching on confession and satisfaction. The Thirty-Nine Articles include indulgences in the list of Romish doctrines rejected as fond things vainly invented (Article XXII).

The Westminster Confession, treating of repentance, makes no mention of the Catholic distinction between guilt and temporal punishment. Reformed theology generally holds that when God forgives sin, he forgives it entirely, with no remaining penalty to be paid by the believer or mediated by the Church.

The deeper Protestant objection is that the theology of indulgences presupposes a bookkeeping model of sin and grace that, in Protestant reading, contradicts the sheer gratuity of the gospel. If Christ's atonement addresses sin completely, there is no remaining ledger to be balanced by human works, ecclesial mediation, or post-mortem purification.

Key scripture the Protestant tradition emphasizes includes Romans 8:1 (there is therefore now no condemnation for those who are in Christ Jesus), 1 John 1:7 (the blood of Jesus his Son cleanses us from all sin), Hebrews 10:14 (by a single offering he has perfected for all time those who are being sanctified), and the general New Testament teaching on the completeness of Christ's atoning work.

The developed doctrine of indulgences as Catholic teaching would later define it is not found in the Fathers. What the Fathers show is an early Christian discipline of penance — acts of repentance (prayer, fasting, almsgiving) undertaken as part of reconciliation after serious sin. The early church required visible public penance for grave offenses, lasting years or even decades in some cases.

By the early Middle Ages, the practice of commuting such public penances — substituting one act for another, or the Church remitting part of the obligation — became established. This developed into what would later be called indulgences. The treasury of merits as a formal theological concept was articulated most clearly in the thirteenth century, especially by Alexander of Hales and Thomas Aquinas.

The patristic witness, then, supports a general penitential framework within which the later doctrine of indulgences eventually developed. It does not explicitly teach that doctrine. Catholics hold that the development is legitimate — that the Fathers' implicit teaching was made explicit by later theology. Protestants hold that the development went beyond what the Fathers taught and beyond what Scripture warrants.

Both traditions agree that serious sin requires serious repentance. Both affirm that the Church has some genuine authority to bind and loose in matters of discipline and forgiveness. Both condemn the historical abuses — the sale of indulgences, the financial exploitation of penitents, the manipulation of grief over deceased loved ones — that Trent itself formally reformed.

Both affirm that salvation is by grace, that Christ's atonement is sufficient, and that the Church cannot add anything to it. On this point, the Catholic Church has been especially careful since Trent to articulate indulgences as drawing upon Christ's merits rather than adding to them.

The Lutheran-Catholic dialogue has produced substantial agreement on the underlying doctrine of justification (as affirmed in the 1999 Joint Declaration), and much of the bitterness around indulgences rested on theologies of merit and satisfaction that both traditions now understand more similarly. The specific practice of indulgences, however, remains in a different category.

The genuine differences remain. Catholics teach and practice indulgences within the conditions set by Indulgentiarum Doctrina. Protestants do not. The theological distinction between the guilt and the temporal punishment of sin is a Catholic doctrine Protestants do not share.

The treasury of merits is a Catholic doctrine Protestants do not share. The Church's power to apply that treasury is a Catholic doctrine Protestants do not share. These are not peripheral; they structure an entire theological ecology — including purgatory, the sacrament of reconciliation, and the communion of saints as practiced in the Catholic tradition.

Practically: Catholics today still participate in indulgences, typically in connection with jubilee years, pilgrimages, specific prayers, and acts of mercy. For an ordinary Catholic, the practice is devotional rather than central — one possible expression of a life of grace. For Protestants, the practice has no counterpart and no place.

The Catholic practice of indulgences, properly understood and reformed from its medieval abuses, preserves something: a concrete acknowledgment that sin has consequences beyond the moment of forgiveness, that repentance includes active works of mercy and devotion, and that the Church as the Body of Christ is a real medium through which grace is applied. It resists the temptation to treat forgiveness as a purely private transaction between the individual and God.

The Protestant rejection of indulgences preserves the instinct that nothing human can be added to Christ's finished work, that the gospel must be protected from the drift toward transaction, and that the Church must remain free of financial or institutional entanglements with the grace it proclaims. The Reformation's critique of specific abuses was justified, and its continuing vigilance is something the Catholic Church has, at its best, come to value.

Modern Catholic teaching on indulgences has narrowed and refined the practice significantly. Protestant teaching on sanctification has, at its best, integrated real penitential and remedial elements without calling them indulgences. The two traditions are not as far apart in substance as they are in vocabulary, but the vocabulary continues to carry the weight of five centuries of misunderstanding. Clearing it is part of this ministry's work.
