This is a really amazing book. Since I haven't done a lot of studying on this subject on my own, I can't tell how sound their scholarship is, but so much of what the authors put forth makes a heck of a lot of sense. Basically, it states that Literalist Christians (Christians of today) have missed the whole point - that the Christ story is not meant to be taken as a historical truth but as an allegorical study. Christians of today are missing the Inner Mysteries and only have the surface Outer Mysteries. Of course, there's so much more and so much explanation; you really have to read this book for yourself. Definitely a highly recommended book on my list.
