We can write a life of Julius Caesar or of Cicero, because we have in the first line letters, commentaries, and other authentic documents written by them and their friends; in the second, lives written by Plutarch and others who had in their hands monuments of them, now lost; and in the third, masses of contemporary coins and inscriptions. Contrast with this wealth of sources the scanty material which remains, after the examination of the preceding chapters, for a portrait of Jesus of Nazareth. So slender is it, indeed, that it seems not absurd to some critics to-day to deny that he ever lived.

... what is poetry to us—akin to the folk-lore of water-sprites, naiads, kelpies, river-gods and water-worship in general—was to Tertullian and to the generations of believers who fashioned the baptismal rites, ablutions and beliefs of the church, nothing less than grim reality and unquestionable fact.

... Paul's Christ is an a priori construction of his own, owing to the historical man of Nazareth and to those who knew that man and cherished his memory little except the bare name of Jesus. Paul's Jesus is an ideal superhuman Saviour, destined, from the beginning of the world, to play an ecumenic rôle.
