In October 1517, Luther wrote his 95 Theses. Many people think that he put them on the door of a church in Wittenberg, but this is not sure. Instead, he published a copy. He presented these to church officials at Worms Cathedral. Luther called them "The Disputation of Doctor Martin Luther on the Power and Efficacy of Indulgences". It questioned the teaching of the western Church and its ideas about penance, the authority of the Pope and the usefulness of "indulgences". At that time, the Catholic Church was selling indulgences to get out of purgatory, and go right to Heaven after death. They were selling indulgences for money for the dead so they could go to Heaven faster. If that was true, it would mean that poor people would not be able to go to Heaven as quickly, but that the priests in the church would be rich from selling these things. Luther thought that this was all wrong, and was against the Bible.
