How so, FK? The term was "coined" to address a Christological heresy and as such really wrote "finis" to that heresy.
I think Xzins nailed exactly where I was coming from in his 5654. Perhaps WAY back in the day, the context would have better understood by the average layman. I'm just saying that today, I don't think it is. To a person who didn't know what was behind it, "mother of God" "sounds" bad for the reasons already discussed. However, with a full explanation, then it's OK. In the same way, "mother of Christ" "sounds" bad to you because it has a defined meaning under Nesotrianism. However, Nestorianism aside, it "sounds" perfectly good to me, and if I said I thought it was OK, and then gave you a full explanation of what I meant by it, you would probably say "fine" to the idea I was conveying, just in that context.
Do we really have to redefine our terms because some people don't know enough to figure such things out correctly? Political correctness run amok!
It is not Forest Keeper who is redefining words.
The "Mother of God" says exactly what its words mean.
The "Mother of the Incarnate 2d Person of the Trinity" means exactly what it says.
The 2d is an effort to communicate precisely. The first is an effort to speak in code, to intentionally be confusing, or to be misunderstanding of the Trinity. Mary was not the mother of the Father. The Father is just as likely to be called God in our Trinitarian system as is the Son.
Do you think Mary is the Mother of the Father?
This is easy to remedy. When in need of instriction in the faith ask the Catholics or the Orthodox, and it will be better understood.
