What? Using Scripture to correct erroneous teaching is heresy? It’s better to change Scripture and create more error instead?
Weird world Catholics live in.
You need to read about Arianism which you are espousing.
God is fully God while also being fully Man.
As a part of mankind he was developed in His Mothers womb for nine months and she then gave birth and nursed her Son.
Mary was Jesus human Mother therefore she can be properly called “The Mother of God”.
To not be able to call her that would be to deny His humanity thus you would be guilty of the Arian heresy.
