During the 16th century’s tumultuous years of religious reformation and revolution, Pilgram Marpeck consistently but discreetly stood up to the ruling powers, calling for freedom of religion and separation of church and state. Walter Klaassen and William Klassen, editors of The Writings of Pilgram Marpeck, have deeply mined Marpeck’s writing and dialogue with other Reformation leaders. They place his life, work, and theology in the context of his violent, changing times. This thorough biography shows how Marpeck, perhaps more than any other early Anabaptist figure, helped lay the theoretical and practical foundations of the believers church.
