The thought made Luther a reformer at once. He started to purge his order of Pharisaism, and the university of the dross of Aristotle. Soon he was called upon to protest against one of the most obtrusive of the "good works" recommended by the church, the purchase of indulgences. Albert of Hohenzollern was elected, through political influence and at an early age, to the archiepiscopal sees of Magdeburg and Mayence, this last carrying with it an electorate and the primacy of Germany. For confirmation from the pope in the uncanonical occupation of these offices, Albert paid a huge sum, the equivalent of several hundred thousand dollars today. Mayence was already in debt and the young archbishop knew not where to turn for money. To help him, and to raise money for Rome, Leo X declared an indulgence. In order to get a large a profit as possible Albert employed as his chief agent an unscrupulous Dominican named John Tetzel. [Sidenote: Tetzel] This man went around the country proclaiming that as soon as the money clinked in the chest the soul of some dead relative flew from purgatory, and that by buying a papal pardon the purchaser secured plenary remission of sins and the grace of God. The indulgence-sellers were forbidden to enter Saxony, but they came very near it, and many of the people of Wittenberg went out to buy heaven at a bargain. Luther was sickened by seeing what he believed to be the deception of the poor people in being taught to rely on these wretched papers instead of on real, lively faith. He accordingly called their value in question, {67} in Ninety-five Theses, or heads for a scholastic debate, which he nailed to the door of the Castle Church on October 31, 1517. [Sidenote: The Ninety-five Theses, 1517] He pointed out that the doctrine of the church was very uncertain, especially in regard to the freeing of souls from purgatory; that contrition was the only gate to God's pardon; that works of charity were better than buying of indulgences, and that the practices of the indulgence-sellers were extremely scandalous and likely to foment heresy among the simple. In all this he did not directly deny the whole value of indulgences, but he pared it down to a minimum.
