When Martin Luther appeared before the assembly (Diet of Worms, April 17, 1521) for examination of his heretical teachings, Johann von Eck (assistant to the Archbishop of Trier), spoke for Emperor Charles V. Eck showed Luther a table filled with copies of his writings and asked if he still agreed with what was written. Luther asked for time to think about his answer. His extension granted, Luther prayed, consulted others and came before before the Diet the next day.
When asked the same question the next day, Luther apologized for the harsh tone of some writings, but could not reject the majority of them or the teachings therein. Respectfully, but forthrightly, Luther 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."
--Martin Luther. On May 25, 1521, Emperor Charles V issued his Edict of Worms that declared Martin Luther an outlaw.
