And soon to come out Richard Bauckham's Jesus and the Eyewitnesses: The Gospels as Eyewitness Testimony published by Eerdmans in September 2006 and Simon Gathercole's The Pre-existent Son: Recovering the Christologies of Matthew, Mark and Luke - published by Eerdman's apparently in Feb 2006 but only available here in proof form! Amazon says it is due out in October!
Interesting thesis from an outstanding young scholar.
Both of these books seem to be stepping out against the whole paradigm that the Gospels are historical reconstuctions with invention at their core. It will be worthwhile studying them when they come out!
