Publishes ‘To the Christian Nobility of the German Nation’

In this tract, Luther expounded his views concerning the ‘priesthood of all believers’ and the ‘two kingdoms’. Luther attacked the ‘three walls’ Roman Catholicism had erected to defend itself: (1) that secular authority has no jurisdiction over the Church; (2) that only the pope is able to explain Scripture; (3) that nobody but the pope himself can call a general church council.
