Explanations of the Ninety-Five Theses

The Explanations of the Ninety-Five Theses (Resolutiones disputationum de indulgentiarum virtute) is Luther's own commentary on the theses he had circulated at the end of October 1517. The theses had been composed as propositions for an academic disputation, but they spread through Germany within weeks, were read as settled assertions, and drew attacks from Johann Tetzel, Johann Eck, and Sylvester Prierias. Luther wrote the Explanations in early 1518 to say what each thesis actually meant, to distinguish what he was proposing for debate from what he was prepared to defend, and to show that his objections rested on Scripture, the fathers, and canon law. He sent the work to Rome with a letter to Pope Leo X and a dedicatory letter to his superior Johann von Staupitz, and it was printed in Wittenberg in August 1518.

The work opens with a protestation: Luther declares that he asserts nothing contrary to Scripture, the church fathers, the canons, or papal decrees, but that he will not be bound by any authority outside these. He then takes the theses in order. On the first, he argues from the Greek metanoia that Christ's call to repentance means the whole life of the believer, an inward turning rather than a sacramental act to be completed and paid off. On the power of the keys, he distinguishes penalties the church imposes, which the pope may remit, from penalties God imposes, which he cannot, and he concludes that indulgences have no bearing on souls in purgatory except by way of intercession. On absolution he argues that what makes the priest's word effective is the penitent's faith in Christ's promise, not the priest's power or the penitent's contrition. On the treasury of the church he insists the true treasure is the gospel of the glory and grace of God, and in this section he sets a theology of the cross against a theology of glory, a contrast he developed the same spring at the Heidelberg Disputation. Throughout, he professes obedience to the pope while subordinating papal authority to the Word of God.

The Explanations matter because they show the reformer's theology taking shape under pressure, before the break with Rome was decided. The themes that would define his later work, repentance as a life, faith as the means of receiving forgiveness, the cross as the test of all theology, Scripture as the final norm, are here as arguments rather than slogans, still framed in the idiom of a loyal churchman. Anyone who wants to know what Luther meant in 1517 should read him here rather than infer it from the theses alone.

Who should read this: readers of church history and Reformation theology who want to see Luther's first full account of his own position, and pastors or students working through the relationship between repentance, faith, and absolution. It is not a devotional work; readers looking for Luther's warmth and pastoral directness will find it in his sermons and The Freedom of a Christian, not in this closely argued defense.
