This small volume, the latest addition to the growing library of translations of the noted German theologian and martyr, consists of lectures delivered by Bonhoeffer at the University of Berlin in 1933, and reconstructed here from notes by his friend and literary executor, Eberhard Bethge. The volume is offered to indicate what might have been the ""positive"" side of Bonhoeffer's theology, to which he himself often referred but was prevented from completing by his execution by the Nazis. Although delivered before his thought was tried and matured by the events of the final years of his life, the theological position defined in these lectures is felt to be, by those responsible for the volume, substantially in accord with what Bonhoeffer would have said had he lived to complete his theological writings. Three parts were planned for the lectures: the first deals with Christ as ever present; the second with the Historical Christ, with a critical appraisal of the ""negative"" theologies of Christ; and the third--never delivered--was to have dealt with the Eternal Christ. The book will be of immediate appeal to the large number of students and readers who have been drawn to Bonhoeffer's thought on grounds ranging from theological speculation to personal faith.
