Lutheran theologian. He joined M. Luther in 1517 and accompanied him to the Disputation of Leipzig (1519) and the Diet of Worms (1521). In 1524 he went to Magdeburg to lead the Protestant opposition to the Catholic clergy and to reform the services on Lutheran lines. He objected to the Leipzig Interim (1548) and became one of the leaders of the Gnesio-Lutheran party opposed to the Adiaphorists. Against G.Major and others, he maintained that good works were not only useless but actually harmful.
