As Tetzel continued his traffic and his impious pretensions, Luther determined upon a more effectual protest against these crying abuses. An occasion soon offered. The castle church of Wittenberg possessed many relics, which on certain holy days were exhibited to the people, and full remission of sins was granted to all who then visited the church and made confession. Accordingly on these days the people in great numbers resorted thither. One of the most important of these occasions, the festival of “All Saints,” was approaching. On the preceding day, Luther, joining the crowds that were already making their way to the church, posted on its door a paper containing ninety-five propositions against the doctrine of indulgences. He declared his willingness to defend these theses next day at the university, against all who should see fit to attack them. His propositions attracted universal attention. They were read and re-read, and repeated in every direction. Great excitement was created in the university and in the whole city. By these theses it was shown that the power to grant the pardon of sin, and to remit its penalty, had never been committed to the pope or to any other man. The whole scheme was a farce,—an artifice to extort money by playing upon the superstitions of the people,—a device of Satan to destroy the souls of all who should trust to its lying pretensions. It was also clearly shown that the gospel of Christ is the most valuable treasure of the church, and that the grace of God, therein revealed, is freely bestowed upon all who seek it by repentance and faith. Luther’s theses challenged discussion; but no one dared accept the challenge. The questions which he proposed had in a few days spread through all Germany, and in a few weeks they had sounded throughout Christendom. Many devoted Romanists, who had seen and lamented the terrible iniquity prevailing in the church, but had not known how to arrest its progress, read the propositions with great joy, recognizing in them the voice of God. They felt that the Lord had graciously set His hand to arrest the rapidly swelling tide of corruption that was issuing from the see of Rome. Princes and magistrates secretly rejoiced that a check was to be put upon the arrogant power which denied the right of appeal from its decisions.
