Luther wrote out 95 reasons why the Catholic Church was corrupt and needed reformed. He nailed the 95 Theses to the door of the Whittenburg Church. This was the common way of debating other scholars.
Luther brought up three important “Walls of the Romanists”. First, “if pressed by the temporal power, they have affirmed and maintained that the temporal power has no jurisdiction over them…that the spiritual power is above the temporal.” Luther believed the Church did not have divine right to excuse itself from judgment of impiety by members of the church who are not ordained.
Second, “if it were proposed to admonish them with the Scriptures, they objected that no one may interpret the Scripture but the Pope.” Luther believed a person is enlightened to the truth of Scripture by the work of the Holy Spirit applying everything it contains. Luther did not see a problem with the general public having a Bible in their own vulgar languages.
Third, “if they are threatened with a council, they pretend that no one may call a council but the Pope”. Luther did not agree with the Pope in that he should have sole power to call a council. A council was usually called to deal with doctrinal questions. The Pope believed people should just agree with all his positions without debate because he is somehow the special mediator between God and man.
Seems Luther and this writer disagree with the Pope. Jesus is the only Mediator between God and man.
