The Old Testament, basically is formed by copying other faiths and Myths from the Mesopotamia region. Specially the Hebrew God and the way he acted shows that is more like a egoistic, Narcissistic, with human behavior instead of Divine.
For instance we have in the early Jewish faith, that Jaweh had a Goddess wife, Ashira. So that's gone now...Basically it was the Old Testament, and all the violence, hate, and rules by a misogynist God that turned me to become agnostic. What kind of God is this when he demands from the supposedly chosen nation to go kill everyone and keep the virgins for themselves(Numbers chapter 31)no difference from what Isis is doing, following the Bible rules!
Or what kind of God demands for woman to be stoned to death because she didn't scream while being raped, or if she screams then she can married the person that raped her, as long as he pays compensation to her father!!! Or when a woman defends her self from a rapist and grabs the testicles of the offender the penalty is to chop her hand off....really give me a f..,.ing break. This is not God.
During the centuries the Catholic/Orthodox Church, they have vanished many other books connected to the Hebrew Bible and mostly the Hellenic Scriptures, since it didn't fit their agenda like the Gospel of Thomas, Gospel of Maria Magdalene, Gospel of Judas, Gospel of Nicodemus, Faith and Wisdom.
