You and I are going to have to disagree here.
God is a Trinity.
While it is true that there is an inasciable nature to the origin of the three persons in the Trinity. It is not true that this precludes the reality, that an earthly brith of Jesus (who is God the second person) means God was created by Mary.
That is false, the title of Mary as “Mother of God” is there besides the reality of the origin of the persons of the trinity.
You are getting hung up on the idea that to be a Mother is to bring about the creation of a thing. That is not motherhood.
Only God creates a soul for example. To be a mother does not actually mean to be the sole-origin of a person.
One can be a “mother” of an adopted Child. One can also be a surrogate mother. The humanity of Christ had to come from Mary. Since his humanity is fully and not partially united to his divinity (by necessity for salvation of all humanity), Mary bore the Son of God.
Further, to be “God bearer” (theotokos, which you would understand the meaning of if you’ve studied this) does not imply begetting of the essence of God. It implies the necessary communication between the two natures God and Man in one person Jesus Christ.
Thus when Jesus acts to die on the cross both his Human and divine natures are through the action of one person. His humanity dies and this act is done in unity with his divinity.
Otherwise, his atonement is merely the act of a man and not God.
Why would God die on the cross? Why would God be born of a woman? To accept one and deny the other is incomprehensible. God came into the world and God died in it, or else God did neither of those things and our faith is in vain.
Saying that Mary is the mother of God is saying a different thing than saying that Mary is the mother of Jesus.
Your disagreement is with the Holy Spirit then as HE is the one who calls Mary *mother of Jesus* in the Scripture that He inspired and breathed out, never referring to her as *mother of God*.
The Catholic church is wrong and guilty of the sin of presumption that they like to accuse others of so much, in presuming to correct what the Holy Spirit inspired as not being adequate or accurate.
The Holy Spirit did not need them to come along and correct something He revealed as if He didn’t do a good enough job of revealing it in the first place.
God was born unto Mary to become Man....humble birth, suffering, humility...humility, humility....Jesus had great love and respect regarding his mother and urged us to do the same...this even if He were not God would fulfill duty to God under the Commandments given to Moses. I see nothing in Jesus word that relegate his mother as only a vessel for birth...I see many references, even to his death that praise her and ask others to embrace her. A loving God would do this for this extraordinary woman, a woman who served Him without question. You would have us believe she was of no significance in Our Lord’s eyes than you or me? Experience is everything in my small life... My spiritual experience with the holy Mother of Jesus Christ in prayer, along with generations of my family has been phenomenally rewarding.
