We do not say that Mary is the mother of diety, but that she is the mother of God, who is Jesus, God, made man

Mary gave birth to her creator, Jesus was , as St Thomas said in the bible,"My Lord and My God!" Elizabeth said, "How is it that the mother of my Lord should come to me?" It is a statement of faith. Jesus is God. Just because you cannot understand how the trinity is possible with your human intellect, dont make it untrue, there is no person who can fully understand God, if we could he wouldnt be God. We make the intellectual ent of faith by claiming that Mary was themother of God. This is biblical. Mary giving birth to a nature is not truth. mothers give birth to persons, this mother gave birth to God, who was called Jesus, or Emmanuel meaning God is with us.
