In these lectures, C. Arnold Snyder offers an important historical study on the subject of religious toleration in the period of the Reformation, breaking new ground based on his own careful reading of Lutheran and Swiss Anabaptist sources. Snyder sheds new light on the nature of Swiss Anabaptism in the latter half of the sixteenth century, demonstrating that by the end of the century, the Anabaptists of Switzerland were no longer running from "the world" but actively engaging those in power and courageously lobbying for religious toleration. This historical inquiry also provides an occasion for contemporary reflection on faith and toleration today, in the context of rising social, political and religious tensions.
