I never said that it did. Calling Mary God's mother, however implies such.
God is 3 in 1. Mary would have to be the mother of the Father, Son, and Holy Spirit if she were the mother of God.
Mothers give their children beginnings. She would have had to give God a beginning and therefore he wouldnt' be God. UNLESS - there is another agency working here.
By not differentiating amongst the persons of the trinity, a whole lot of confusion is thrown into the mix. If people would just call her mother of Jesus like the Bible does, the confusion disappears.
Jesus IS God. Mary is His Mother. But she is not the mother of the Father or of the Holy Spirit. And God is not 3 independent parts, but one. So, calling her Mary mother of Jesus is the most proper way to refer to her.
This notion treats each of the Divine Persons of the Trinity as *parts* of God. But the *Persons* of the Divine Trinity are not parts of God. Each of the three Persons is God, not a part of God. That is why the line in the Athanasian Creed reads, "So the Father is God, the Son is God, and the Holy Ghost is God. And yet they are not Three Gods, but One God."
No wonder you are having a hard time with "mother of God". First get your understanding of the Trinity straightened out, and "mother of God" will be no problem.
