###Input: The enforcement of the ban on the 95 Theses fell to the secular authorities. On 18 April 1521, Luther appeared as ordered before the Diet of Worms. This was a general assembly of the estates of the Holy Roman Empire that took place in Worms, a town on the Rhine. It was conducted from 28 January to 25 May 1521, with Emperor Charles V presiding. Prince Frederick III, Elector of Saxony, obtained a safe conduct for Luther to and from the meeting.

Johann Eck, speaking on behalf of the Empire as assistant of the Archbishop of Trier, presented Luther with copies of his writings laid out on a table and asked him if the books were his, and whether he stood by their contents. Luther confirmed he was their author, but requested time to think about the answer to the second question. He prayed, consulted friends, and gave his response the next day:

At the end of this speech, Luther raised his arm "in the traditional salute of a knight winning a bout." Michael Mullett considers this speech as a "world classic of epoch-making oratory."

Luther refused to recant his writings. He is sometimes also quoted as saying: "Here I stand. I can do no other". Recent scholars consider the evidence for these words to be unreliable, since they were inserted before "May God help me" only in later versions of the speech and not recorded in witness accounts of the proceedings. However, Mullett suggests that given his nature, "we are free to believe that Luther would tend to select the more dramatic form of words."

Over the next five days, private conferences were held to determine Luther's fate. The Emperor presented the final draft of the Edict of Worms on 25 May 1521, declaring Luther an outlaw, banning his literature, and requiring his arrest: "We want him to be apprehended and punished as a notorious heretic." It also made it a crime for anyone in Germany to give Luther food or shelter. It permitted anyone to kill Luther without legal consequence.
