"Loewen's work must be considered dated, but that is to be expected. Despite that, this work retains several strong points in its favour. Loewen, in his own way, had already begun to tackle the task of revisionism. 'Luther and the Radicals' remains a successful attempt to bridge centuries of misunderstandings between the Lutheran and the Radical Reformations. Loewen organized his work using such categories as Wittenberg Radicals, Evangelical and Revolutionary Anabaptists, Spiritualists, Antinomians and Antitrinitarians. Such labels are not popular at present, but they continue to make sense from a pedagogical and systematic (if not necessarily historical) perspective" (p. 66-67). "I consider 'Luther and the Radicals' a very useful introductory text for students of the Radical Reformation" (p. 67).
