Is the belief on the Theotokos prior to the schism?
Yes, but it is not really about Mary of Nazareth. It is about Jesus of Nazareth.
Jesus of Nazareth is fully human and fully Divine. Everyone realizes this is a paradox, it is not logical. As Christians we have to live with paradox.
Some Christians wanted to separate Jesus’ humanity from His divinity. There were a lot of reasons why, some of it has to do with “high Christology”, in other words emphasizing Our Lord’s divinity over His humanity.
Some other people (adoptionists) actually thought that Jesus became Son of God long after His birth, by adoption, when He was baptized in the Jordan. (Thus Mary would not be ‘God-bearer’.) Many likewise speculated that the divinity left Him before He died on the Cross (the “impassibility” of God) because God does not suffer death.
Some others (Arians) were convinced that Jesus was not divine at all, but completely human.
There was a concern that some people using the term '
Theo’-tokos might forget that Jesus was fully human too.
The church affirmed that Christ was begotten of the Father before all ages, outside of time. It also affirmed that He was born of Mary the virgin
in time. We have an incarnational theology. We believe God did become man in Jesus, conceived of the Holy Ghost.
Thus, Mary of Nazareth did bear God. She is a hero figure…she said yes to the challenge. So we honor her for her decision and her role in the life of Jesus.
But the theology is all about Jesus. It was not a conciliar decision to elevate Mary of Nazareth to a new place, it was to affirm that Jesus is the Son of God, and there is no separation at any part of Jesus’ life from being divine.
The followers of Nestorios were more comfortable with calling her Christotokos, the bearer of Christ. It is not really a bad term, it’s actually true, but it leaves wiggle room for some people who may have personal reservations about just exactly what the precise relationship of Christ is with God.
So the Council of Ephesus decreed that the term Theotokos is appropriate for her, and we should praise her in that way. The council also deposed Nestorios, apparently for persecuting Christians who used the term.
A secondary problem is that the term, whatever it is, can be observed by some people more as a title of honor for her than a description of what she did for God. It wasn’t like she was being given a new place in salvation history, or a new job.
We praise her for what she did for God, and we ask for her prayers on our behalf, in the hope that her prayers on our behalf will be more efficacious than our own.
It is a hope.
Or did both East and West come to this knowledge independently?
No.
It is dogma that she bore God in her womb.
