No...... It is simply stating where his humanity came from. Mary could not give birth to God.
God existed before Mary was born. Did his humanity? Yet, you are saying she gave birth to God. As if God can be created. Then God, is not God, but a creation.
When Jesus body laid in the tomb dead? Was that dead body God?
Jesus is the full manifestation of Deity in bodily form. Just as the burning bush was a bush with Deity being manifested. Moses saw, and spoke to that bush as if it were God himself. Now, if someone planted the seed for that bush? Would he be called the farmer of God?
The problem is you resort to name calling and accusation without understanding what was said. Its a failure to see the essence and nature of God. God can not be born. To say he can be reveals that you do not even know what God is. It is like saying God can die.
It appears you are simply following a certain teaching's buzz words without the ability to question it, and using a form letter accusation when you get stuck in running out of any ability to form a sound argument based upon the words of the Bible to take a stand.
Please? Use chapter and verse to make your stand? For your stand must be based upon the Scripture and remian consistent with what it teaches. If Mary gave birth to God, then God can die. Mary's ovum could only produce a human body. The Deity of Christ remained untouched as the humanity of Christ died. If that is nestorianism, then Nestorius was correct and that council was living in the dark. Just like the council was in the dark when it condemned Martin Luther who was light years ahead of those who condemned him.
Those were primitive days for the Church in many ways. Yet, some look to them as being more advanced than those walking in the Spirit today. They must have been more advanced back then? Why? After all, they would burn you at the stake if they saw you as walking in error. Quite a spiritual way to be. No?

Think! What does the Word say! Not, what did certain men say.
