Mary is mother of the Second person of the Trinity Jesus Christ. She is not a mother only of His human nature but of His whole eternal person. Likewise she is not directly the mother of any other person of the Holy Trinity, the Father or the Holy Ghost. Christ's whole person is God, just like the Father is God and the Holy Ghost is God. God is one (*). Mary is the mother of God.

Now, various modern sects don't understand that, since obviously the Eternal Son as well as the entire Holy Trinity pre-existed Mary. For guidance they should read the fathers of the Church and pray. St. John the Damascene is a good start, AN EXACT EXPOSITION OF THE ORTHODOX FAITH, BOOK I.

The views contrary to the Ephesian Canons are anathema not because I in my arrogance declare them such, but because, for over a millenium and a half, which is virtually since as soon as they were formulated, they have been. It is a historical fact. The Christian way to deal with anathemized views, should you have them, is to drop them, and then struggle for explanations, and the explanation will come, God willing.

(*) Interestingly, if Mary is construed to be the mother of the Second person but not mother of God, then that would put her in a singular relation with the Second Person compared to the other Persons. Then she would be a fourth person of God, which is probably far from the neo-nestorians' intention.

And one last post before I go, simply because this is too good to pass up:

She is not a mother only of His human nature but of His whole eternal person.

So are you saying

1) that Mary is as eternal as God, making her a Goddess in her own right or
2) that God is not really eternal, but began to exist at Jesus' conception?

Either way puts you in a state of complete heresy. Only if make some level of distinction between Yeshua's God-nature and Man-nature--while, of course, acknowledging that Yeshua was fully both--do you avoid this trap.
