It’s Reformation Day! On October 31, 1517 Martin Luther defiantly nailed a copy of his 95 Theses to the door of the Wittenberg Castle church. These 95 theses were a list of questions and propositions that Luther wished to debate. The first two of the theses contained Luther’s central idea, that God intended believers to seek repentance and that faith alone, and not deeds, would lead to salvation. The other 93 theses, a number of them directly criticizing the practice of indulgences, supported these first two. These 95 Theses would later become the foundation of the Protestant Reformation.
