Frères de la vie commune
Anabaptists are considered to have begun with the Radical Reformation in the 16th century, but historians classify certain people and groups as their forerunners because of a similar approach to the interpretation and application of the Bible. For instance, Petr Chelčický, a 15th-century Bohemian reformer, taught most of the beliefs considered integral to Anabaptist theology. Medieval antecedents may include the Brethren of the Common Life, the Hussites, Dutch Sacramentists, and some forms of monasticism. The Waldensians also represent a faith similar to the Anabaptists.
