On This Day in Church History

A real event from the story of the church on each calendar day, told with its setting and what came of it, and quoted word for word from sources published before 1931.

On this day · October 31

October 31, 1517 · Wittenberg, Germany

The setting

Martin Luther was an Augustinian monk and professor of theology at Wittenberg. He was troubled that indulgences were being sold to ordinary people as a way to escape punishment for sin, and he wanted the issue debated.

The story

Dated October 31, 1517, Luther put out ninety-five statements for academic debate on the power of indulgences. The opening line invited scholars to discuss them, out of love for the truth. They were written in Latin for scholars, but printers soon spread them across Germany.

The first thesis set the tone for everything that followed: Christ's call to repent is not a single act but describes the whole life of a believer. Later theses argued that the church's true treasure is not money or merit, but the gospel itself.

“Our Lord and Master Jesus Christ, when He said Poenitentiam agite, willed that the whole life of believers should be repentance.”

Thesis 1

“The true treasure of the Church is the Most Holy Gospel of the glory and the grace of God.”

Thesis 62

What happened next

The debate Luther hoped for became a movement. Within a few years he was excommunicated and stood before the emperor at Worms in 1521. The Reformation reshaped Western Christianity and put the Bible in ordinary people's hands in their own languages.

Why it matters: Luther's first thesis is still a good daily reminder: following Jesus means a whole life of turning back to God.
