Christ is God. Christ is born to Mary. The icon I just posted shows the Father as well as the Holy Ghost apart from the Son. Clearly no one in 15th century Novgorod would think that the Father was born, and I assure you no one would think that Christ is not God. Now, I understand that Protestant exegesis is lacking here, but again, it is not my problem.
I don't care what some man's painting says. I care what Scripture SAYS. God is one. Calling Mary the mother of GOD makes her the mother of the Father and the mother of the Spirit. Mother of Christ is fine, though Scripture calls her mother of Jesus and mother of my Lord. You can not use imprecise language with a term like this. Mother of God is imprecise. Mother of the God-man Jesus Christ might work - but Scripture, as usual, will suffice.
