Despite his “holy” life as a monk, Luther constantly doubted his salvation. Relief came in his study of Paul’s letter to the Romans, which revealed to him the pure Gospel. But this also sparked concerns about the church’s practice of selling indulgences, which contradict the Gospel. Feeling a need to protect his flock and start a scholarly debate, Luther posted his 95 Theses in Wittenberg. His writings were distributed throughout the land, sparking the events that began the Reformation.
