But the real occasion of the revolt of the northern nations of Europe against the jurisdiction of Rome was the controversy regarding indulgences. "These in the Catholic church, are remissions, to penitents of punishment due for sin, upon the performances of some work of mercy or piety, or the payment of a sum of money." When Leo X. was elected to the Papal dignity (1513), he found the church in great need of money for the building of Saint Peter's and other undertakings, and he had recourse to a grant of indulgences to fill the coffers of the church. The power of dispensing these indulgences in Saxony in Germany was given to a Dominican friar named Tetzel. This fanatic enthusiast entertained the most exaggerated opinion of the efficacy of indulgences. In his harrangues he uttered such expressions as the following: "Indulgences are the most precious and the most noble of God's gifts." "There is no sin so great that an indulgence can not remit; ... only let him pay well, and all will be forgiven him." "Come, and I will give you letters, all properly sealed, by which even the sins that you intend to commit may be pardoned." "I would not change my privileges for those of St. Peter in heaven; for I have saved more souls by my indulgences than the apostle by his sermons." "The Lord Omnipotent hath ceased to reign; he has resigned all power to the Pope." See D'Aubigne's History of the Reformation, Book III, Chap. 1. Martin Luther was an Augustine monk and a teacher of theology in the University of Wittemberg. Before Tetzel appeared in Germany, Luther possessed a wide reputation for learning and piety, and he had also entertained doubts respecting many of the doctrines of the church. During an official visit to Rome in 1510 he was almost overwhelmed with sorrow because of the moral corruption there; but while penitentially ascending on his knees the sacred stairs of the Lateran, he seemed to hear a voice thundering in his soul, "The just shall live by faith!" This marked an important epoch in his career.
