Luther’s 95 Theses: On Halloween of 1517, Martin Luther changed the course of human history when he nailed his 95 Theses to the church door at Wittenberg, Germany accusing the Roman Catholic church of heresy upon heresy. Many people cite this act as the primary starting point of the Protestant Reformation… though to be sure, John Wycliffe, John Hus, Thomas Linacre, John Colet, and others had already put the life’s work and even their lives on the line for same cause of truth, constructing the foundation of Reform upon which Luther now built. Luther's action was in great part a response to the selling of indulgences by Johann Tetzel, a Dominican priest. Luther's charges also directly challenged the position of the clergy in regard to individual salvation. Before long, Luther’s 95 Theses of Contention had been copied and published all over Europe. Luther's Protestant views were condemned as heretical by Pope Leo X in the bull Exsurge Domine in 1520. Consequently Luther was summoned to either renounce or reaffirm them at the Diet of Worms on 17 April 1521. When he appeared before the assembly, Johann von Eck, by then assistant to the Archbishop of Trier, acted as spokesman for Emperor Charles the Fifth. He presented Luther with a table filled with copies of his writings. Eck asked Luther if he still believed what these works taught. He requested time to think about his answer. Granted an extension, Luther prayed, consulted with friends and mediators and presented himself before the Diet the next day. When the counsellor put the same question to Luther the next day, the reformer apologised for the harsh tone of many of his writings, but said that he could not reject the majority of them or the teachings in them. Luther respectfully but boldly stated, "Unless I am convinced by proofs from Scriptures or by plain and clear reasons and arguments, I can and will not retract, for it is neither safe nor wise to do anything against conscience. Here I stand. I can do no other. God help me. Amen." On May 25, the Emperor issued his Edict of Worms, declaring Martin Luther an outlaw.
