With Bibles and baptism, a movement was born. From renegade gatherings of Christian believers in the 1500s to a global communion of more than 2.1 million members, the Anabaptist-Mennonite movement has been marked by faithfulness and failure, continuity and conflict, radicalism and reformation. In this engaging history, Radicals and Reformers traces the origins and development of the Anabaptist and Mennonite movements from their beginnings in Europe through their spread across the globe. In this new authoritative introduction to Anabaptist history, historian Troy Osborne reflects on the ways that Anabaptists have defined their identity in new settings and in response to new theological, intellectual, geographic, and political contexts. Drawing from current scholarship and a range of written and visual sources, this book provides an overview of how Mennonites from Zurich to Zimbabwe have adapted to or resisted the world around them.
