In his illuminating study in church/state relationships, Leonard Verduin has set forth the evolution of the First Amendment of the Constitution - "Congress shall make no laws touching the establishment of religion, nor prohibiting the free exercise thereof" - as the direct outgrowth and development from the Christian freedom-of-conscience rationale - that for that for which the Apostolic Church and the succeeding Corpus Christi martyr Anabaptist churches - strove, suffered and died! This development is well traced by Verduin, and his volume has become an additional sourcebook for students of Anabaptism.
