ABSTRACT
W H I L E Luther was in retirement at the beautiful old castle near Eisenach, the movement started by him was carried on with accelerated velocity at Wittenberg. Carlstadt's attack on sacerdotal celibacy was only the first step in a revolution. In this movement two distinct factors combined, the one of constructive reform, the other of popular tumult; the best elements of the first were due to Luther, who, while absent, kept up a constant correspondence with Wittenberg; for the second element other leaders were responsible, Carlstadt, Z willing, and the Zwickau prophets.
