INTRODUCTION
"A Disputation on the Power and Efficacy of Indulgences"[1] is the full title of the document commonly called "The Ninety-five Theses." The form of the document was determined by the academic practice of the Middle Ages. In all the Mediæval Universities the "disputation" was a well-established institution. It was a debate, conducted according to accepted rules, on any subject which the chief disputant might elect, and no student's education was thought to be complete until he had shown his ability to defend himself in discussions of this kind. It was customary to set forth the subject which was to be discussed, in a series of "theses," which were statements of opinion tentatively advanced as the basis of argument. The author, or some other person whom he might designate, announced himself ready to defend these statements against all comers, and invited all who might wish to debate with him to a part in the discussion. Such an academic document, one out of many hundreds, exhaling the atmosphere of the Mediæval University, is the Disputation, which by its historical importance has earned the name "The XCV Theses."
The Theses were published on the Eve of All Saints (Oct. 31), 1517. They were not intended for any other public than that of the University,[2] and Luther did not even have them printed at first, though copies were forwarded to the Archbishop of Mainz, and to Luther's own diocesan, the Bishop of Brandenburg. The manner of their publication too was academic. They were simply posted on the door of the Church of All Saints—called the "Castle-church," to distinguish it from its neighbor, the "Town-church"—not because more people would see them there than elsewhere, but because that church-door was the customary place for posting such announcements, the predecessor of the "black-board" in the modern German University. It was not night, but mid-day[3] when the Theses were nailed up, and the Eve of All Saints was chosen, not that the crowds who would frequent the next day's festival might read them, for they were written in Latin, but because it was the customary day for the posting of theses. Moreover, the Feast of All Saints was the time when the precious relics, which earned
