"just like Mary. The salient term is "like""
The salient word is caritovw "full of grace". The believer and Mary have both been made "caritovw".
"After her encounter with Jesus, Mary was incapable of spiritual death. "
So you believe in the preservation of the saints? :)
"We go furthermore, of course, to say that from before all time she was destined to choose life over death."
I though predestination was anathama?
"Full of grace" proves nothing.
Even you have to admit her encounter was something special. Talk about a "personal relationship with Jesus."
Who said that predestination is anathema? Double predestination, maybe.
