The importance of Luther to the Christian faith cannot be overstated. For many today, he is probably a figure who looks larger as a symbol of defiance or a heroic rebel against a corrupt church and decadent theology. There is much truth in such images. His stand at the Diet of Worms was a remarkable act of courageous defiance. And his theology represented nothing less than a self-conscious attempt to overthrow the medieval thought which he had been taught and replace it with a comprehensive understanding of God and the gospel as refracted the incarnate and crucified Christ.
