Unknown Johann Eck Johann Eck Johann Eck was a man who defended the [Roman Catholic] church. He wrote booklets against Luther, saying that he was a heretic just like John Huss. Eck and Luther had debates, discussing the differences between their beliefs. At one debate in Leipzig in the summer of 1519, Eck got Luther to say that the pope was in error. Luther stated that Scripture is the Word of God and there are no mistakes in God’s Word. If there is a disagreement between the pope and the Bible, we must agree with God’s Word rather than the pope’s. Eck thought he had won the debate when he got Luther to say that he believed the pope was not the supreme truth, but many people believed Luther was the real winner because he boldly stated the truth.
