Once again: Bultmann’s incarnation problem
Bultmann wrote: 'The only way of presenting revelation is as the annihilation of everything human, the refusal of all human questions, the rejection of all human answers – in short, as the putting of man into question' (cited in John Ashton's brilliant work: Understanding the Fourth Gospel, p.58)
'There is no getting round the Incarnation, and Bultmann set his face resolutely against any attempt to water it down: 'The Revealer appears not as man-in-general, i.e. not simply as a bearer of human nature, but as a definite human being in history: Jesus of Nazareth. His humanity is genuine humanity: "the word became flesh".' But for all his vaunted anti-docetism, Bultmann presents a Christ in whom all salient individual characteristics have been flattened out: the splendid 'I am' sayings in which so much of his revelation is contained have but a single message: 'All that I say is I.' The incarnate Christ is no more than a voice, his particular and contingent human qualities all drawn off, volatilized, until there is nothing left but a smear on a slide--the ultimate essence of a Word' (Understanding the Fourth Gospel, p.65, italics mine)
Ashton's book, by the way, is one of those special volumes that is simultaneously academically heavyweight at the same time as being a delight to read, difficult to put down.
But less you think Ashton's criticisms imply disrespect for Bultmann (or mine in citing them), he still speaks of him as 'unmatched in learning, breadth, and understanding [... towering] like a colossus' (45).
