Apples and oranges. I am not asking you to accept our beliefs but only what we mean when we, Catholic CHRISTIANS, say "Mother of God." We do not mean the mother of the Trinity or the mother of Jesus' divinity, only the mother of the one divine person, Jesus Christ. To imply that we do otherwise is to bear false witness to our beliefs. Or are you only interested in winning cheep debating points?
Your certainly entitled to believe what you want.
However, words mean things.
When you call Mary, the Mother of God, the implication is she is the mother of the Father and the Holy Spirit. It also gives the meaning God had a beginning. Neither of which are supported by Scripture.
I do not consider these "cheap debating points".
To correct a false doctrine is not a cheap debate point. Nor is calling out how Islam and Mormonism redefine terms to suit their needs, much as the catholic does with this issue, an apples and oranges comparison.
It either lines up with the Word or it doesn't.
The title, "Mother of God", is not supported by Scripture as much as the catholic wants it to be.
