I am pressed for time. There is wikipedia, I suppose. What this book purport to do? Who is the author?
The Israelites had to have nonBiblical sources from the Canaanite culture which they emerged. I saw all those fertility goddess, depicted as Jehovah's wives on PBS. One picture is worth a thousand words. Polytheism is always breaking out in the Bible. It is reported so frequently that I wonder if polytheism wasn't the norm and then a Jehovah cult emerged much later than Bible chronology would dictate.
If this is just a Mormon book.............They make the Witnesses look so respectable. Yet if you don't know the teachings, live on the East Coast, they seem as solid as any Protestant sect. I should not talk since my knowledge is from Big Love.
