President Obama's mother must be "greater" than the President, and he must have gotten his presidency from her, since she's accepted as the President's mother (and not merely "Barack Obama's mother").
Be careful - many of Barry Hussein Soetoro's acolytes and devotees probably think he is a divine being, at least by looking at their faces, and I'll bet that many of them could be convinced of Ann Dunham special exalted status with your logic.
The problem with your analogy is that Jesus Christ, is 'monogenes'; single, unique, the only one of his kind. He is God incarnate, the God man. Unlike Deity, Presidents and firemen are all created beings who did not preexist so there is generally no ontological confusion or category error when ascribing titles to their mothers.
As far as I can tell there has been only one post on this entire thread by one poster who objects to the basic Christian doctrine that Jesus was God when he was in Mary's womb, and it is because that poster DENIES the Deity of Christ, (and by "Deity" I mean "the state of being God"). None of the other objectors to the ascription, "Mother of God" deny the Deity of Christ, and certainly not the one to whom you replied, so your reference to "... people objecting to the basic Christian doctrine that Jesus was God" is an unresponsive straw man.
And just about this whole thread illustrates daniel1212's point about the general lack of qualifiers in the ascription:
Now if Catholics typically added such a qualifier, that Mary is the mother of God as concerning the flesh (as she provided none of His Divine nature, but which provided her), who is over all, God blessed for ever," then it would be more tolerableRomulus is to be credited (at least on this point if not on other points:^) for providing the necessary qualifiers (at #359, 360 & 362), but generally it's like pulling teeth to get some RC's to even acknowledge the necessary ontological distinctions.
That there are difficulties inherent with the "Mother of God" descriptor is also evident from daniel1212 sourced list of instances of "hyper-exaltation" of Mary, which are factual instances and not merely hypothetical consequences of the practice, and to this documentation you made no response.
Cordially,
In the face of patient explanation you continue to insist that “Mother of God” is an unwarranted exaltation of Mary. Do you not understand that with the same logic you must say that “Jesus is the Son of Man” is an exaltation of all of us?
Oh, wait.
The Redeemer is Emanuel. One either believe God is “with” us, or one does not. Being perfect, God does not do things halfway, so if Jesus is Emanuel, God is wholly “with-us”, as much as Adam. Is our human nature glorified in being joined in Jesus to the divine nature? You bet it is. The Resurrection and Ascension are occasions for joy because the victory has been won by God-with-us who is one-of-us.
If you believe Jesus is Emanuel, you cannot escape the truth that Mary is the Mother of God.
