Ninety-Five Theses

Martin Luther wrote the “Ninety-Five Theses: A Disputation to Clarify the Power of Indulgences” in 1517. These statements were called “theses” because they were meant to provide a basis for later arguments, much like the statements that students base academic papers on today. This guide refers to The Ninety-Five Theses and Other Writings, translated by William R. Russell, published in 2017 by Penguin Books.

Martin Luther sent a copy of the theses along with a letter to Archbishop Albrecht von Brandenburg on October 31, 1517. Luther may have placed a copy of the theses on the door of All Saints’ Church in the northern German town of Wittenberg. Although the image of Luther posting his theses to the church door has become famous in art, historians debate whether he actually did so. It was customary to use church doors to show announcements and writings to the community. If Luther did post the theses, it was a routine act of presenting one’s writings to the public, not an act of defiance.

Nonetheless, Luther’s theses made a splash. October 31, the day he chose to send his theses to Archbishop Albrecht, was All Saints’ Day, an important holy day on the Catholic Church’s calendar.
