According to Bullock, Hitler considered the Protestant clergy to be "insignificant" and "submissive" and lacking in a religion to be taken seriously. Hitler attempted to create a unified Protestant Reich Church from 28 separate regional churches through "Gleichschaltung". His bid to create a unified Reich Church ultimately failed, and Hitler became disinterested in supporting the so-called "German Christians" Nazi aligned movement. Hitler initially lent support to Ludwig Muller, a Nazi and former naval chaplain, to serve as Reich Bishop, but his heretical views against Paul the Apostle and the Semitic origins of Christ and the Bible (see Positive Christianity) quickly alienated sections of the Protestant church. Lutheran Pastor Martin Neimoller created the Confessing Church movement to oppose the Nazification of Protestant churches. Neimoller was arrested by the Gestapo in 1937, and sent to the concentration camps. The Confessing Church seminary was prohibited that same year.
