Namaste Zenda,
yes, i've read the book. it is my opinion that Pagels does a very good job in her research and her selections of texts to present. i'm fully aware of the difficulties invovled in working with the papyri from the Nag Hamadi find.. her and the other researchers have my gratitude.
as for the conclusions that she has drawn..well... they seem fine to me

of course, i was always a bit left of center when i was a Christian in any regards.. thus, it's probably not all that important if it makes sense to me or not.
one of the things that i found particularly fascinating was the political climate that existed at the first and second councils of Nicea where the Bible that we have today was codified. these are, of course, very much the same as the three Buddhist councils where the Tipitaka was first written down and fixed as the Canon.
