Prefatory Note: In July, 1976, Rudolf Bultmann, the last of the great Protestant theologians of this century, died in Marburg, Germany, a few weeks before his 92d birthday. An almost life-long friendship, beginning with my being his student in the 1920s, bound me to this man of towering scholarship, clarity of mind, purity of character, and deep — if troubled — piety. In November, 1976, the Theological Faculty of Marburg University held a memorial for its longtime professor of New Testament studies, which was attended by many persons from all over Germany and neighboring countries this side of the iron curtain. Of the two academic lectures delivered before that audience, one was by a New Testament theologian and erstwhile student of Bultmann, Professor Erich Dinkler from Heidelberg, the other by me, not a theologian but a philosopher, not a Christian but a Jew. The complete proceedings of the memorial meeting have been published under the title Gedenken an Rudolf Bultmann by J. C. B. Mohr in Tübingen, 1977. Only part of what I had prepared in writing was orally presented at the occasion, but the whole was printed. I here submit my own English version of the unabridged German essay, which in the spirit of Bultmann's own openmindedness pushes some of his theoretical concerns beyond the point which he himself had reached.
