Would you agree that Mary is the Mother of God?
Mary is the Mother of Jesus Christ. Jesus is God. But Mary was not before Jesus. Mary was part of God's incarnation in that her womb bore the Son of God. But, God is eternally preexistant - therefore, to say Mary is the Mother of God throws unnecessary confusion into the matter. Mary is not Divine. She did not contribute to the Son's divinity. She contributed to His humanity in that He became a man and passed through her womb and birth canal in the normal human way.
Mary was a mother. But our Lord Jesus existed far before Mary came on the scene. So was she technically the "Mother" of God. No. Not in the sense you mean it.
