If you mean that Mary is the mother of Jesus, then just SAY it.
There's no need to change her title, making her into something she isn't.
GOD has no mother, no beginning. Jesus did. Jesus was born. God wasn't.
If you insist that Mary is the mother of God because she's the mother of Jesus, then you are denying Jesus' humanity and falling into the error of modalism.
Explain why saying that Mary is the mother of God denies the humanity of Jesus.
Jesus has two nature, divine and human. But he is one divine Person. So it is IMPOSSIBLE for Mary to be the mother of Jesus without being the mother of God.
Why do you constantly raise this objection when it has NOTHING TO DO with the title "Mother of God." Once again, the title "Mother of God" has NEVER meant that Mary is the origin of the eternal, Triune God. It has always meant that, because Mary is the mother of Jesus, and Jesus is one divine Person, not two persons, Mary is the mother of God.
You seem to be a user of the English language, yet when it comes to this issue, you seem to lapse into a kind of psychosis, in which language makes no impression on you. When you look at the words I write, do you see words, or just random letters? Or is it all a blur?
Catholics understand the dual nature of Jesus as human and divine. It was stated that the Word became Flesh. The two natures are combined and not separate.
So through the grace and actions of God, Mary became the Mother of God, Jesus, both his human and divine natures.
So do you not believe that God can do all things? Do you not believe that Jesus is both God and human? So do you split Jesus in half and deny that He is both? Your logic and reason escapes me.
Did you listen to whole interview of Tim Staples where he explains the importance of Mary and the need to accept her as the Mother of God?
