Wouldn't this string of logic then infer that God did not exist until Mary gave birth to him?
No, not at all, not to us today; but you are experiencing the same thing that faced Christian theologians in the first century.
We have the Most Holy Trinity. The Trinity and Monotheism existing together. God the Father, God the Son, God the Holy Spirit, yet one God.
This question is what the early Christological heresies were all about. How could this be? God incarnate, coming into the finite world, yet still the infinite God?
How can this be? Yet it is. God became incarnate, the Word became flesh, born of a woman. This we know.
Now, how do we Christians deal with this - and the One True God.
We cannot deal with it by denying the reality of the Incarnation. We cannot say it didn't happen, that the Word did not become flesh born of a woman and dwelled among is. He had a mother and her name was Mary. The incarnation really happened. We cannot say it did not and remain Christian.
We must start from here.
This is to revisit the early Church and the heresies of who Christ is. We revisit this again on this thread.
I appreciate your reply and hope you do see the point here and why it is important.
Sorry, can’t by the whole Mary thing. Mary is part of the creation. God has always been. Something finite (Mary) cannot give birth to something infinite, eternal, pre-existent to the creation (God). God has always been. God always will be. Mary cannot be greater than God.
Unless you start thinking like Mormons, who say we can eventually become Gods ourselves, which would imply that somehow Mary gave birth to a being that evolved into God. But again, where did Mary come from if God had not already existed.
Scripture is clear. God the Father, Son and Holy Spirit have always been and always will be. Mary is definitely blessed, but not greater than her son. Respect and honor is due her, but she was a part of the fallen creation, who needed a Savior as much as any other sinner. I thank Mary for her part, bearing the Son, being obedient to God, her (and Joseph) being of such character and devotion to be given this per elide, and for suffering as she did at the foot of the cross. An exceptional woman for any time frame... But I will never ask her to play any sort of intercessory roll in my life. She will never hear a prayer from me. Those are for Jesus alone, as my Saviour and intercessor.
Mary was the vessel used by God to bring Jesus, God incarnate, into our finite existence, but Jesus existed from the beginning, as part of the trinity.
