First I would like to note that the book is well written and well-structured and is very interesting to read, hence the three stars!
However, despite being all this as well as being very illuminating in parts it doesn't offer any real substance as far as the Historical Jesus goes. The author is obviously a 'Lena' (sorry about the pun) towards the Jesus seminar stuff and thinks Crossan is a voice for the mainstream, not sure about that! Also the 'hypothesis', despite being very honest about it being a 'Hypothesis' is nothing more than a personal idea and lacks any concrete evidence. Paul and Jesus being the same person is just pie in the sky! I raise much more problems than it solves and is just unconvincing to say the least. For example, when Paul goes to Jerusalem to find out about the man he encounters in his vision there is clearly a community in place with its own take on Jesus, and Paul is clearly in one accord with the main thrust of the movement, though they do obviously have their major differences. For me, the hoo har created about circumcision and food laws is one thing, but Paul proclaiming himself in Jesus is quite something else! Also, I am not surprised in that much of Jesus is not mentioned in the pagan and Jewish text, Jesus, to them is just one of many who fell by the power of Rome, though there are strong fingerprints over the texts concerned that Jesus did exist as Lena, leans towards, (sorry I will stop it now. However, the worst part or me is the psychological intellectual bullying hinted at, i.e., if you don't agree with me then you are simply not a 'free thinker'. I find this sentiment quite childish and sill. Just because people don't agree with your views does not mean they are not 'free thinker', perhaps you simply haven't demonstrated the evidence strongly enough, if it's there, and in this case it certainly is not! Often the most acclaimed 'free thinkers' I have encountered have been the most myopic and dogmatic characters I have ever met, ironically with no 'freedom' in their own thoughts. On a childish level it's a bit like someone asking, `agree with me or if you can't it's your stupidity getting in the way'.
Nevertheless, well written, but not very well argued, but I admire her honesty about it being 'A Hypothesis', unlike some.
