Rudolf Bultmann's courageous thought has been right at the centre of living Christian theology ever since the 194os. There is no doubt that his challenge will be equally crucial for the 196os. What we have so far lacked is an account of `Bultmannism' clearly stating its message for preachers and lay people. Now Dr Bultmann has himself supplied this lack, and has taken the opportunity of making his position sharply clear in response to criticism that he is abandoning the essence of Christianity. For all who ask how Christianity can be restated without the 'myths' of the first century, the appearance of this short book is a help and an encouragement.
