Menno Simon was what most would term a radical reformer - he did not align with nor have tolerance for the state-church system of the magisterial reformers. He was what Leonard Verduin called a step-child of the Reformers. Simon and other so-called Anabaptists were marginalized and persecuted by state-church people on both sides of the English Channel.
Those called Anabaptist included groups that eventually gave birth to such as Mennonites and Unitarians. Far from being a homogeneous group of people, the folk called Anabaptist were varied in their theology, ecclesiology, and doctrine. Simon was part of the Anabaptist movement that held to the sufficiency of Scripture, local autonomy of the assembly of saints, believer's baptism, and a regenerate membership in the local congregation.
