The Changing Faces of Jesus by Geza Vermes
Rather than attempting to retrieve the historical Jesus by eliminating later theological accretions, this book starts by setting out four fully developed portraits, beginning with the most evolved and retreating towards the more primitive. Starting with the fourth gospel (John) with its wholly idealized and deified images of Jesus, Geza Vermes then looks at Paul, who's first depiction of a redeemer figure is directed essentially at non-Jews. Another "face" will be seen through the acts of the Apostles, that of the final prophet of the end of time, a new Moses. Finally, the synoptic gospels each paint their own portrait of a Galilean preacher, healer and exorcist.
