In 1517, the monk Martin Luther published a pamphlet with 95 Theses that he posted in the town square of Wittenberg and handed copies to feudal lords. Whether he nailed them to a church door at Wittenberg remains unclear. The list detailed 95 assertions, he argued, represented corrupt practice of the Christian faith and misconduct within the Catholic Church. Although perhaps not Luther's chief concern, he received popular support for his condemnation of the sale of indulgences and clerical offices, the pope's and higher clergy's abuse of power and his doubts of the very idea of the institution of the Church and the papacy.
