For 22 years, approximately 200 Fellows of the Westar Institute, the Jesus Seminar, have attempted to parse Jesus' alleged utterances into categories of possibly said, unlikely to have said, and impossible to have said. Needless to say, this kind of investigation can get very, very weighty.
Instead, Freke and Gandy have given us a delightful book, which I find quite funny in lots of places, that enables the reader to understand the difference between the literal, historical Jesus and the Gnostic Jesus, even if the reader has no formal background or training. And understanding that difference can make a difference between a Chrisitan experience that is guilt-ridden and one that is enlightening. Maybe other reviewers consider this a trivial pursuit, but I bought a dozen copies for my dearest friends.
