Thanks for taking as much time as you have with my arguments.
However, since you have advanced the theory that (I summarize) "The Fall and Redemption, etc., were necessary in order for Men to become Spiritual Grown-Ups", I must repeat my question regarding the Elect Angels -- who never underwent a Fall, and will never undergo Redemption:
Is it, then, your contention that the Archangels Saint Michael and Saint Gabriel are, well -- "not Spiritual Grown-Ups"?
John the Baptist and other saints of the Old Covenant come to mind. The few, the select, tasked with God's specific purpose, but not fully aware. Just a quick thought, anyway. Angels and humans are not one and the same.
