This treatise is very important because it was the first after the council of Worms and after Luther was convinced that a break with the Pope was, right, inevitable, and necessary. In it he enunciated the three objections he had to the Roman authorities. These he called the three walls of Romanism. This treatise came to be called "cry from the heart of the people." Walls: 1) Romanists are beyond secular authority. 2) Scripture is incomprehensible except to the Pope who alone can explain it. 3) The Pope alone can call a church council of disputation.
