Martin Luther on The Papacy in Rome

"I contend for only two things. First, I will not suffer any man to establish new articles of faith and to abuse all other Christians in the world and slander and brand them as heretics, apostates and unbelievers simply because they are not under the pope. It is enough that we let the pope be pope, and it is not necessary that for his sake God and his saints on earth should be blasphemed. Second, all that the pope decrees and does I will receive on condition that I first test it by the Holy Scriptures. He must remain under Christ and submit to being judged by the Holy Scriptures." - Martin Luther, The Papacy in Rome
