Interesting, and not something I’ve been exposed to before. However, both Adam and Eve were created without original sin - were they not fully human? And the BVM, although preserved from the sin of Adam, made the affirmative choice to refrain from sin throughout her life, succeeding where Eve (also without original sin) failed. Hmm, something to ponder, anyway...
“And the BVM, although preserved from the sin of Adam, made the affirmative choice to refrain from sin throughout her life...”
Contradicts Scripture. If true, then Jesus had no need to die. “I do not nullify the grace of God, for if righteousness were through the law, then Christ died for no purpose.”
