 In the second part of the letter to the Christian nobility of the German nation, Luther debates the point that it is the Pope's sole authority to interpret, or confirm interpretation of, scriptures, the large problem being that there is no proof announcing this authority is the Pope's alone and thus assuming this authority for themselves.Through this criticism, Luther allows the laity to have a standard to base their faith on and not an official's interpretation, thus detracting more from the Church's control over the sphere.This criticism, unlike in the first wall, supported a strong base of the reformation, the break away from the rules and traditions of the Catholic Church.
