[St_Thomas_Aquinas]

And you can prove that assertion just how? Or are we to take your say so?

The dogmatic teachings of Church Councils? The early Christians? The Church Fathers?

The Greek term Theo-tokos means "God-bearer" or Mother of God. It is still the most popular title given to Our Lady in the Eastern Christian Churches. It was affirmed in early Church Councils precisely because it confirmed the Christian claim about who Jesus Christ is and protected the meaning and implications of His Incarnation. The Catechism of the Catholic Church puts it simply," What the Catholic faith believes about Mary is based on what it believes about Christ, and what it teaches about Mary illumines in turn its faith in Christ"

The Greek term Theo-tokos means "God-bearer"...

Why, yes.

"... or Mother of God."

Not really, not so neatly

-- or else they would have come up with a term (of their own invention, such as the word theotokus was invention amid Greek language) that would translate more precisely 'Mother of God' -- provided had that been the intent. Yet obviously, it was not?

They held back from going quite that far with the phrase (on purpose) yet without that slim margin of restraint equating to denying the divinity of Christ be inseparable from His humanity -- at least while the one known as Jesus Christ walked the earth (incarnate) in form of a man.

The same can be said for an alternative "phrase", or word ---Christotokus, which by itself denotes no inaccuracy.

Christ came to this earth in the flesh, in the form of a man, born of the virgin, Mary.

Jesus's very being in this earthly, physical realm was no spectre, not even the body (body of Jesus Christ) which resurrected from the grave, but instead was nothing but the real thing, baby, nothing but the real thing...

There are red herrings, in this world

and there are red cola cans.

Decide.
