Why are they different things to you? I don’t understand this.
Clearly you don't. Nor do a list of other RC's hereon. Shocking.
I don't have the time and energy etc. to give even a short course in psycho-linguistics nor socio-linguistics. However, for some lurkers who still have the capacity to reason and some at least minimally functioning ears to hear and eyes to see . . .
GOD BEARER =
Bearing God; Carrying God; Transporting God; serving God as a cup bearer serves a king . . .
MOTHER OF GOD
brazenly IMPLIES, HINTS AT, ASSERTS PSYCHO-LINGUISTICALLY AND SOCIOLINGUISTICALLY THAT
Mary was BEFORE AND/OR ABOVE GOD ALMIGHTY and continues in some sort of PARENTAL ROLE over HIM.
THAT IS BLATANTLY FALSE, WRONG, INACCURATE, A DECEPTION, A LIE.
That the Vatican Alice In Wonderland School of Theology and Reality Mangling edifice is so brazenly stubborn about CONTINUING TO PROPAGATE THAT DECEPTION, THAT LIE, THAT IMPLICATION
IS VERY TELLING in terms of the idolatries involved.
Now, of course, the weasel worded rationalizations and denials will begin.
