I simply taught, preached, wrote God’s Word; otherwise I did nothing. And then, while I slept, or drank Wittenberg beer with my Philip and my Amsdorf, the Word so greatly weakened the papacy that never a prince or emperor did such damage to it. I did nothing. The Word did it all.
Quoted in Timothy George, Theology of the Reformers, 53, as quoted in Shawn Wright, “Luther’s Battle for Sola Scriptura,” Southern Seminary Magazine.
