While most Christians are familiar with the events and major participants of the Reformation, many still don't know very much about the Anabaptists—a sect of breakaway Christians who rejected the Roman Catholic Church and the idea of state churches altogether. Holding to principles of nonviolence, renunciation of the oath (based principally on Matthew 5:34–37 and James 5:12), and believer's baptism—the Anabaptists were persecuted for their beliefs by Catholics and Protestants. Among the various leaders of this pious group, Menno Simons became so influential, other Anabaptist leaders started referring to his Dutch followers as Mennonites.
