Martin Luther

By itself, widespread criticism of the church did not lead to the dramatic changes of the sixteenth century. Those resulted from the personal religious struggle of a German university professor, Martin Luther (1483–1546). Luther’s father wanted him to be a lawyer, but a sense of religious calling led him to join the Augustinian friars, an order whose members often preached to, taught, and assisted the poor. Luther was ordained a priest in 1507 and after additional study earned a doctorate of theology. From 1512 until his death in 1546 he served as professor of the Scriptures at the new University of Wittenberg.

Martin Luther was a very conscientious friar, but his scrupulous observance of the religious routine, frequent confessions, and fasting gave him only temporary relief from anxieties about sin and his ability to meet God’s demands. Through his study of Saint Paul’s letters in the New Testament, he gradually arrived at a new understanding of Christian doctrine. His understanding is often summarized as “faith alone, grace alone, scripture alone.” He believed that salvation and justification (righteousness in God’s eyes) come through faith, and that faith is a free gift of God, not the result of human effort. God’s word is revealed only in biblical scripture, not in the traditions of the church.

At the same time that Luther was engaged in scholarly reflections and professorial lecturing, Pope Leo X authorized a special Saint Peter’s indulgence to finance his building plans in Rome. An indulgence was a document, signed by the pope or another church official, that substituted for penance. The archbishop who controlled the area in which Wittenberg was located, Albert of Mainz, also promoted the sale of indulgences, in his case to pay off a debt he had incurred to be named bishop of several additional territories. Albert’s sales campaign, run by a Dominican friar who mounted an advertising blitz, promised that the purchase of indulgences would bring full forgiveness for one’s own sins or buy release from purgatory for a loved one. One of the slogans — “As soon as coin in coffer rings, the soul from purgatory springs” — brought phenomenal success.

Selling Indulgences A German single-page pamphlet shows a monk offering an indulgence, with the official seals of the pope attached, as people run to put their money in the box in exchange for his promise of heavenly bliss, symbolized by the dove above his head. Indulgences were sold widely in Germany, and they were the first Catholic practice that Luther criticized openly. This pamphlet also attacks the sale of indulgences, calling it devilish and deceitful, a point of view expressed in the woodcut by the peddler’s riding on a donkey, an animal that had long been used as a symbol of ignorance. Indulgences were often printed as fill-in-the-blank forms. This one, purchased in 1521, has space for the indulgence seller’s name at the top, the buyer’s name in the middle, and the date at the bottom.(woodcut: akg-images; indulgence: Visual Connection Archive)

Luther was severely troubled that many people believed that they had no further need for repentance once they had purchased indulgences. He wrote a letter to Archbishop Albert on the subject and enclosed in Latin his “Ninety-five Theses on the Power of Indulgences.” His argument was that indulgences undermined the seriousness of the sacrament of penance and competed with the preaching of the Gospel. After Luther’s death, biographies reported that the theses were also posted on the door of the church at Wittenberg Castle on October 31, 1517. Such an act would have been very strange — they were in Latin and written for those learned in theology, not for normal churchgoers — but it has become a standard part of Luther lore. In any case, Luther intended the theses for academic debate, but by December 1517 they had been translated into German and were being read throughout central Europe. Luther was ordered to go to Rome, but he was able to avoid this because the ruler of the territory in which he lived protected him. The pope nonetheless ordered him to recant many of his ideas, and Luther publicly burned the letter containing the papal order. In this highly charged atmosphere, the twenty-one-year-old emperor Charles V summoned Luther to appear before the Diet of Worms, an assembly of representatives from the territories of the Holy Roman Empire meeting in the city of Worms in 1521. Luther refused to give in to demands that he take back his ideas:

Unless I am convinced by the evidence of Scripture or by plain reason — for I do not accept the authority of the Pope or the councils alone, since it is established that they have often erred and contradicted themselves — I am bound by the Scriptures I have cited and my conscience is captive to the Word of God. I cannot and will not recant anything, for it is neither safe nor right to go against conscience.4
