:: The ultimate cooperation was God asking the Blessed Virgin to bear the Savior ::
That’s some \serious\ heterodoxy there.
I recommend you read more...MUCH more...of the church Fathers.
Focus on Chrysostom and Augustine.
God doesn’t “ask” mankind anything.
If you are saying God doesn’t “ask” mankind anything, are you saying He commands or dictates? That He ordered Noah to build the Ark, Moses to lead the people out of Egypt, Jonah to preach to Nineveh, etc.? If you’re saying that, there were a lot of these “commands” that were argued with. Moses and Jonah, especially, argued with God about His “commands.” If God commands, there is no Free Will.
