It has NOTHING to do with Sabellianism. Only Nestorians claim it does.
You, Sir, are a closet-Nestorian.
So, I take it this means you think that Mary carried the Father and the Spirit in her womb, as well?
I guess I can start referring to Catholics as "Patritokosianists" then.
Nevertheless, your point is ridiculous. Mary did not carry "God" within her, she carried "God the Son" within her, which is why people who want to be correct in their theology observe that Mary is Christotokos, rather than Theotokos - and this is true, regardless of whatever the Nestorians might have said.
To say "Christ" IS to say "God the Son," because the Messiah, even from what we see in the Old Testament, is God the Second Person of the Trinity incarnated in human flesh.
The problem is that you Catholics are sloppy in your use of terminology because by saying "God" without further specification of the Person to which you are referring, you are basically affirming that all three Persons were in Mary's womb - which is obviously incorrect. That is, in fact, Sabellianism because while you affirm that there are three Persons, you confuse them with respect to their functions and their roles, and by saying Mary is "Theotokos," in fact, you de facto reject the separateness of the Persons within the unity of the substance of the Godhead.
The Nestorians were quite right to use the term "Christotokos," they were merely wrong in what they meant by it.
So you’re a Nestorian.
To say that Mary carried God does mean she carried Father and Son. Only a Sabellian would say that.
But then Nestorians accuse everyone else of Sabellianism.
I notice you did not address the schizoid issue.
Be a Nestorian, Chistotokian, whatever.
I’ll stick with Orthodoxy.
“that you Catholics are sloppy in your use of terminology because by saying “God” without further specification of the Person to which you are referring, you are basically affirming that all three Persons were in Mary’s womb “
Actually I did specify the Son.
I just said that if she carried the Son she carried God because the Second Person is fully God. That’s Nicea.
Or are you an Arian rather than a Nestorian? At least Nestorius accepted Nicea. He just thought that the only way Christ could be fully human was to be both a human person and divine person.
We “Catholics” (you left out the Eastern Orthodox) believe He was a single divine Person with a full human nature united to himself. The “self” was divine, second Person, Son. The Father is a different Person but equally God. The Spirit is a different Person but equally God. The Second Person carried by Mary doesn’t have to have the Father and Son incarnated with him in order to be God.
God the Son was incarnated in Mary. Not schizoided. She was God’s mother. Not the Father’s mother nor the Spirit’s mother but the Second Person Incarnate’s mother. God’s mother.
Period.
