Brown, Italy and the Reformation to 1550 (1933); Ludwig von Pastor, The History of the Popes, from the Close of the Middle Ages, 3rd ed., vol. 7–8 (1950); and Herbert M.

The posting of the theses

Luther was long believed to have posted the theses on the door of the Castle Church in Wittenberg, but the historicity of this event has been questioned. The issue is discussed at length in Erwin Iserloh’s Luther zwischen Reform und Reformation (1966; published in English [1968] as The Theses Were Not Posted). Iserloh indicated that the first known reference to the story was made by Philipp Melanchthon in 1546 and that Luther never mentioned the posting of his theses on the church door. He suggested that Luther wrote to the bishops on October 31, 1517, did not receive an answer, and then circulated the theses among friends and learned acquaintances.

Some later research, however, lent support to the traditional belief. In his contribution to Luthers thesenanschlag: faktum oder fiktion (2008; “Luther’s Posting of the Theses: Fact or Fiction”), for example, Martin Treu discussed a note written by Georg Rörer, a close collaborator of Luther’s, in a copy of the New Testament that he and Luther used for revisions of the Bible. The note read:

In the year of our Lord 1517, on the eve of All Saints’…[theses] about indulgences…were posted on the doors of the churches in Wittenberg by Dr. Martin Luther.

But Rörer, like Melanchthon, was not a witness to the event and could have merely assumed that the posting had taken place in keeping with the statutes of the university at Wittenberg requiring that theses for public debate be posted on the doors of all Wittenberg churches. Scholars remain divided on the question.
