No Mother of GOD in evidence.
Jesus is God, so this is an obvious deduction. But your comment illustrates why the early church councils felt the need to emphasize that Mary was the Mother of God (Θεοτόκος): denial of this logically leads to a denial of either Jesus' full divinity or his full humanity. To quote Cyril of Alexandria's response to the Nestorian heresy: "I am amazed that there are some who are entirely in doubt as to whether the holy Virgin should be called Theotokos or not. For if our Lord Jesus Christ is God, how is the holy Virgin who gave [Him] birth, not [Theotokos]?"
No; logic is NOT one of your strong points.
Too bad the actual WRITERS of the NT didn't feel the need!
The title *mother of Jesus* was used in Scripture BY THE HOLY SPIRIT, to identify MARY, not JESUS.
*mother of Jesus* identified which of the many Mary's the Holy Spirit was referring to. It was ever used to declare Jesus divinity.
So the Catholic church's excuse for changing that is invalid. It's not their business to try and correct what they see as errors in how the Holy Spirit inspired Scripture.
