Mary is the mother of Christ. God has no mother.
Calling Mary the mother of GOD is clearly implying that God has a mother, therefore is a created being, putting Mary above God and making God subservient to Mary.
Saying that she is the mother of God is disingenuous, stating as fact something that is not actually true.
Catholics convoluted logic cannot change the meanings of words and the message they convey. If Catholics have to go though such semantic gymnastics to explain that what is said isn’t really what it means, they have failed, in very many ways.
And Christ is…
putting Mary above God and making God subservient to Mary.
That would be an error, but not a necessary one. We have the Magnificant, young Jesus at the Temple, and the wedding at Cana as examples of how this relationship was.
Saying that she is the mother of God is disingenuous…
It would be unless Christ is God and Mary is His mother. Then it is a clear statement of the Incarnation, the Word become flesh, born of a woman, dwelling among us.
