4.) ABOUT PAUL:
Paul speaks about his mystical, transcendent experience in 2 Corinthians 12 where he is caught up to the third heavens etc.
While in a transcendent, trance-like altered state of consciousness people can experience hypergraphia - a compulsion to write extensively about spiritual realities.
This is comparable to channeling or automatic writing whereby while in a transcendent, trance-like altered state of consciousness, your subconscious goes into over drive and you begin to unleash images, visions, words, thoughts, words etc. from the deep levels, inner recesses of your subconscious/unconscious mind.
I believe this is where Paul's "creative exegesis" of the Old Testament (OT) came from to produce his writings in the New Testament (NT).
According to Genesis 3:17-19 only Adam and Eve were cursed. There is no mention by God of the extension of the curse to Adam and Eve's children and later descendants.
There is also no mention of "the Fall" and/or the extension of the curse to Adam's and Eve's offspring, in the remaining chapters of Genesis or the other 38 books (Protestant Bible) of the OT.
The idea of Adam and Eve passing on sin, imperfection, sickness and death to their offspring was not expounded upon in the OT. It was Paul who later claimed this in his "creative exegesis" of the OT (Romans 5:12, 17 - 19, 1 Corinthians 15: 21, 22 etc).
