Or do you think that word 'God' is properly used only to refer to the conjunction of all three divine Persons, not to any one of the three Persons?

I don't believe you can separate the three members of the Trinity from being one God. I affirm the line from the Athanasian Creed. But my point is that you have to be very very careful about throwing the term "God" around and I don't believe you should go beyond what Scripture itself expresses. I believe the church was wrong to give Mary the title. It brings confusion. Their explanation is fair enough - though her exaltation beyond Scripture's guidance is not.
