Book excerpt: The European Reformation of the sixteenth century was one of the most formative periods in the history of Christian thought and remains one of the most fascinating events in Western history. The Cambridge Companion to Reformation Theology provides a comprehensive guide to the theology and theologians of the Reformation period. Each of the eighteen chapters is written by a leading authority in the field and provides an up-to-date account and analysis of the thought associated with a particular figure or movement. There are chapters focusing on lesser reformers such as Martin Bucer, and on the Catholic and Radical Reformations, as well as the major Protestant reformers. A detailed bibliography and comprehensive index allows comparison of the treatment of specific themes by different figures. This authoritative and accessible guide will appeal to students of history and literature as well as specialist theologians.
