The question, What did Paul know about Jesus of Nazareth?, has long been debated by students of the New Testament. The debate has not issued in any consensus. Indeed, critical appraisals of Paul's relation to the Jesus of history and to traditions about him have been unusually disparate. Thus, on the one side, W. D. Davies has argued that ‘Paul is steeped in the mind and words of his Lord.’ On the other side, R. Bultmann could claim that ‘the teaching of the historical Jesus plays no role, or practically none, in Paul’. The contrast between these two assertions is puzzling, and all the more so as neither can be regarded as idiosyncratic: Davies is not alone in avowing that sayings of and traditions about Jesus were of momentous significance for Paul, and it is not difficult to find critics at one with Bultmann. Moreover, as our two quotations do not simply represent two circles of opinion but also mark poles between which appears a variety of viewpoints, matters are even further complicated.
