Two of the most brilliant German thinkers of the twentieth century were Karl Jaspers and Rudolf Bultmann. Jaspers, the philosopher, and Bultmann, the theologian, were both influenced by the philosophy of Martin Heidegger and the rise of the existentialist movement. Late in their careers they interacted on the subject of Bultmann's attempt to divest Christianity of its mythical components and make sense of it in more modern terms.<BR>This running debate is a compilation of articles originally published in various scholarly journals by Jaspers and Bultmann. The first half of the book is Jaspers's lengthy and critical analysis of Bultmann's interpretation of Christianity. Finally, in response, Jaspers accepts some of Bultmann's clarifications but takes him to task on the subject of "justification by faith," which he feels Bultmann defines too narrowly and too exclusively.
