So you're asserting that Judaism was basically pure and Holy, before the Talmud, with it's genocide, rape, baby killing, slavery & constant war? Basically, if we only could go back to the Law, as it was written in Leviticus, the world would be perfect?
The Pentateuch, including Leviticus, was written as The Law post-Babylonian exile.
Think ofJudaiam as being like Software
Judaism 1.0 = Hasidic
Judaism 2.0 = Messianic
Judaism 3.0 = Ashkenazi
Judaism 4.0 = Catholic
Judaism 5.0 = Muslim
Judaism 6.0 = Protestant
Judaism 7.0 = Mormon
You can subdivide the sects into minor updates like Shia Islam as Judaism 5.1
It's just a story, not historical. What we do know is when the Jews were exiled and when they wrote the stories. Moses didn't "write" anything, nor did "Mark".
