She does not have to be mother of the other persons of the trinity to be the mother of God. This is essential to what it means to say one God in three distinct persons. The Son can be sent to be born to Mary (Gal 3:4).
Since Jesus is God that necessarily means that Mary is the Mother of God.
but Mary cannot bear God. She bore Jesus, the human form taken by God the Son.
Jesus humanity and divinity are unseparated and unmixed They are one reality in One distinct person of the Holy Trinity. You've got to grasp the distinctions here.Its not illogical it is entirely what actually happened.
The rest of your questions are not worth bothering an answer too since you still haven't understood Christianity at all yet. You've got questions making errors about the Holy Trinity, and errors about the person of Jesus. Why should we bother jumping into another long discussion until we have solved this most essential truth about Jesus and the Trinity and Mary the Blessed Mother of God? No. Its not worth it to get distracted.
How so? Are you denying that the other persons of the trinity are God?
Jesus humanity and divinity are unseparated and unmixed
Which is it? Unseparated, meaning mixed, and unmixed meaning separated. Jesus IS God and man; but did the eternal God die on the Cross, or was it Christ's sinless humanity? If God died, is he God?

They are essential because your Church teaches that Catholics believe in a false God. We can't begin to solve any issues until I know where YOU stand. Do you agree with Rome, and assent to CCC 841 that states Catholics and Muslims adore the same ' merciful God', thereby stating that you worship Allah, or do you dissent from Rome's teaching and deny that Catholics worship the same 'God' as Muslims, thereby admitting that the CCC is in error? Where do you stand? I AM Christian; I worship the one true, Triune, Living God.
