Abstract
This essay concentrates on the reception of Oswald Spengler's book, „Der Untergang des Abendlandes” by German Protestant theologians in the early 1920s, who were more susceptible to the influence of this book than were philosophers. Just after the First World War, for example, Werner Elert, Karl Heim and Ernst Troeltsch – not to mention Emanuel Hirsch, Friedrich Gogarten and others – had to cope with deeply interconnected crises in faith, church, theology and nation. Spengler's idea of cycles in history seemed to help them understand Germany's 1918 defeat not as due to military exhaustion but to a sort of divine destiny. But it also gave hope that this destiny would help to overcome the crisis. The authors drew epon certain aspects of Spengler's thinking to establish their theory of Christianity. However, the influence of Spengler vanished soon enough. As a result, the story of his reception is an example of the struggle to locate Christianity within post-war German society.
