How could a woman conceive a divine Person in her womb, and give birth to him?
Heck if I know! But it’s a dogma of the Christian Faith that she did so.
The Second Person of the Trinity has existed from eternity. Mary became his mother WHEN SHE CONCEIVED HIM IN HER WOMB as a man. It was at that instant that he BECAME MAN.
The title “mother of God” has NEVER meant that Mary was in some way the the ETERNAL origin of the ETERNAL WORD. God the Father is the eternal begetter of the Eternal Word, God the Son.
So, railing against the notion that Mary existed eternally is to rail against an idiotic idea that no Christian has ever held.
They know that. They cannot bring themselves to admit that the Catholic teaching on this is exactly what they believe, so they keep trying to change Catholic doctrine so they can disagree with it. Contrarians all.
