On October 31, 1517, Martin Luther nailed his 95 theses to the church door in Wittenberg. What would follow even he didn't fully realize. In celebration of this anniversary, I present the following clip, taken from the 1953 film version of Luther's story. It features the climactic speech at the Diet of Worms.
Sola Scriptura. Sola Fide. Sola Gratia. Solus Christus. Soli Deo Gloria. Amen.
