My biggest reason for walking away from the faith I was raised in, practiced to the point of even becoming a Minister of said faith, and then questioning the faith after delving into research which took years to procure- is something very basic and simple.
I studied the Torah. To make a long post a bit short- various names, their meanings and their lack of vowels point to a really bad misinterpretation of texts when applying outside sources to the Hebrew Torah.
The very first name for god in the first text is Elohim, which literally translates to 'gods'. There was the cult of Yahweh which was practiced in both Israel and Judah during the 9th to 6th Cent. bce as thuse we receive the holy Tetragrammaton, the YHVH.
From this point, we also have the consort of Yahweh, who was recognized not only in text but also in the Canaanite pantheon which lived among the Hebrews, Asherah- The Queen of Heaven. The infamous Jezebel of the Chronicles was a follower of Asherah, and when Elijah lit the fires in his test to prove Ba'al Hammon was a dead god, the Israelites killed Ba'al Hammon's priests, but not those of Asherah. They were mentioned, but not accounted for being slain. Why? Because Asherah was El's consort, as El was associated as Yahweh, after taking on the name of El.
The Hebrews practiced Monolatrism
, not Monotheism. After a time, Monotheism became the practice as all the Canaanite gods slowly became synonymous with Yahweh. Asherah was finally evicted out of the Second Temple, considering it took a long time to finally deny her as a consort. YHVH no longer needed a consort apparently.
