I love to listen to John Shelby Spong's talks... we are fortunate now to have access to lots of them through YouTube. Also, I think that the author's writing skills are equally exquisite, and have no problem confessing I have all his books. I gave the book a maximum rating... and please note that my evaluation is probably skewed by the fact that I just find the author and his mind really fascinating and getting better with each work.
In this context, my criticism is directed specifically against what seems to be a redundant use of Christian or Biblical vocabulary. I think John Shelby Spong has as much in common with traditional mainstream Christianity as Christian Science or Course in Miracles.
Author's brilliant imagination combined with delightful reframing skills generate truly fascinating story which does not need to be linked to any tradition - I think it deserves attention and recognition on its own rights.
Although I did not find this time that much of the fresh and new patterns as advertised, those less familiar with more advanced aspects of Vedanta or even Buddhism, would find here some refreshing rehashing of the elements of those traditions presented here in a more western way.
So, while I have not found too much new things under the Sun in this book (in fact, I do not agree there is any really new vision presented there), I still believe it is another brilliant example of John Shelby Spong mind operating at full speed, which makes it a read worthy book again!!
