The Anathemas of the Second Council of Constantinople, Number 3.

If anyone says that God the Word who performed miracles is one and Christ who suffered is another, or says that God the Word was together with Christ who came from woman, or that the Word was in him as one person is in another, but is not one and the same, our Lord Jesus Christ, the Word of God, incarnate and become human, and that the wonders and the suffering which he voluntarily endured in flesh were not of the same person, let him be anathema.

We get a clue here to the kind of teaching that the council came together to deal with. Comment? Questions?
