Something will usually have to be said about the historicity of the Gospels. You who are trained theologians will be able
do this in ways which I could not. My own line was to
say that I was a professional literary critic and I thought I did know the difference between legend and historical writing:
that the Gospels were certainly not legends (in one sense they're not good enough) : and that if they are not history then they are realistic prose fiction of a kind which actually never existed before the eighteenth century. Little episodes such as Jesus writing in the dust when they brought Him the woman taken in adultery [John 8:3-8] (which have no doctrinal significance at all) are the mark.
