"All 'his' own perception"; doesn't make it true. He is stating his own opinion, not church doctrine. Mary called God her savior in the Magnificant. She is not the co-Redeemer. She is a sinner saved by grace....and by grace alone.
Yes, because He did so preemptively.
She is not the co-Redeemer.
Nor does the Catholic Church teach that.
She is a sinner saved by grace....and by grace alone.
Nope, she never sinned, though grace touched her life like none other.
