Throughout his magnum opus, Church Dogmatics, Karl Barth converses with the great theologians of post-reformation orthodoxy, quoting from works in his private collection. When Barth became Honorary Professor of Reformed Theology at the University of GÃ¶ttingen in 1921, his knowledge of the Reformed tradition was practically non-existent; he quickly amassed his collection of ancient copies in order to acquire a thorough knowledge of orthodoxy. In Karl Barth and Post-Reformation Orthodoxy, Rinse H. Reeling Brouwer identifies and discusses the sources of Barth's conversations and analyses Barth's use and (mis)understandings of them. Each chapter focuses on one of the topics in Christian Dogmatics, with the last chapter exploring the way in which Barth's role as a reader of the 19th-century writer of a textbook on Reformed Dogmatics Heinrich Heppe influenced the ultimate shaping of Church Dogmatics. Reeling Brouwer offers a major contribution to Barth scholarship and an important resource for theologians as well as historians focusing on the post-reformation protestant theology.
