This historically significant volume collects Karl Barth's lectures on John Calvin, delivered at the University of Gottingen in 1922. The book opens with an illuminating sketch of medieval theology, an appreciation of Luther's breakthrough, and a comparative study of the roles of Zwingli and Calvin. The main body of the work consists of an increasingly sympathetic, and at times amusing, account of Calvin's life up to his recall to Geneva. In the process, Barth examines and evaluates the early theological writings of Calvin, especially the first edition of the Institutes."
