Pietism is the religious-theological movement which formed a bridge between the Reformations of the sixteenth century and the Enlightenment. This introduction to the Pietist theologians demonstrates the influence that this movement had on the religious, cultural and social life of the seventeenth and eighteenth centuries, and examines its lasting effects on modern culture and modern theology. Written by an international group of leading scholars, the book explores the transconfessional and transnational aspects of Pietism, considering the contribution of both Protestant and Catholic theologians in Puritan England, Pietist Europe and Colonial America. Each chapter focuses on a particular theologian, from Arndt to Wesley, and incorporates up-to-date research and commentary. Comprehensive yet accessible, this is the ideal introduction to the study of this core theological movement.
