For me, the issue goes to the importance of a name and most especially, a Name of God.
And it is why the Jewish mystics refer to God the Creator as Ayn Sof which literally means "no thing." The point is that any time we sincerely use a word to describe God, we reduce Him in our own minds to the limits of our language. Or to put it another way, no mortal words can define God and when we use them that way then we are mentally creating a reduced false image of a 'god' who is not God, an idol.
Another example, though not in the language of words but of art is the beautiful albeit woefully misleading Michaelangelo painting "The Creation of Adam" showing Adam and God touching fingers. It presents God as an old gray-haired man on a cloud. That is not God but a reduction of Him.
Which brings me back to the titles given to creatures in an attempt to reveal Who God IS by description of the creature.
The title "Mother of the Incarnate Word" does not require a footnote in the mind of the hearer because God the Creator's Name is Word and the phrase "mother of the incarnate" further defines Mary, a creature.
And God said unto Moses, I AM THAT I AM: and he said, Thus shalt thou say unto the children of Israel, I AM hath sent me unto you. Exodus 3:14
Remember the former things of old: for I [am] God, and [there is] none else; [I am] God, and [there is] none like me, - Isaiah 46:9
Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am. John 8:58
So just like admiring the beautiful Michaelangelo painting with a younger requires us to then explain that God is not an old gray-haired man on a cloud, using the title "Mother of God" with a younger requires us to explain that there was no thing and no one and no time before God. Otherwise the younger may walk away with a reduced image of God, a false 'god' of his own imagining.
God's Name is I AM.
