Karlstadt's answer was published in 1524 in Wittenberg, and is still extant. This showed that Karlstadt continued to reject the violence that led to the German Peasants' War. Another defamation was Luther's accusation that Karlstadt was not authorized to preach at the city church in Wittenberg during Luther’s stay at Wartburg. The conversation ended when Luther gave Karlstadt a guilder and told him to write against him. In September 1524 Karlstadt was exiled from Saxony by Frederick the Wise and George, Duke of Saxony. Luther also wrote against Karlstadt in his 1526 "The Sacrament of the Body and Blood of Christ—Against the Fanatics".
