In lecture 6, Dr. Trueman discusses the Leipzig Debate, which he views as a watershed moment in Luther’s life. Luther arrives in Leipzig surrounded by armed students. Before the debate, he preaches from Matthew 16 on the keys of the Kingdom, raising the ire of John Eck, who declares him to be Bohemian (referring to John Hus). It starts to become clear that the issue for Luther is authority, although at the time he probably doesn’t recognize this himself.
The lecture covers John Eck, Andreas Rudolph Bodenstein von Karlstadt, John Hus, the Council of Constance, Luther’s three treatises, and Luther’s view on the imminent return of Christ.
