No one has ever believed that "mother of God" means that Mary existed before the eternal Word, the Second Person of the Trinity. Thus, your constant, obsessive railing against that stupid belief, that NO ONE has ever believed, is absurd.
Your proposition that Mary is the mother of the BODY of Jesus only, and not the mother of the Second Person of the Trinity, is a heresy for which Luther, Calvin, Melancthon, Cromwell, and every other Protestant founder would have burned you at the stake.
You really, REALLY need to learn classical Christological dogma, which is believed in common by ALL true Catholics and ALL true Protestants.
Did you stamp your widdle foot when you posted that? LOL
And you can prove that assertion just how?
Or are we to take your say so?
