The Council of Ephesus (431)
The Second Anathema: One Christ with His Own Flesh
If anyone does not confess that the Word of God the Father is united hypostatically to flesh, and that with that flesh of his own he is one single Christ, both God and man at the same time: let him be anathema.
Nestorius’s second counter-anathema: If anyone asserts that, at the union of the Word with the flesh, the divine essence moved from one place to another; or says that the flesh is capable of receiving the divine nature, and that the divine nature has been partly united with the flesh; or ascribes to the flesh, because it received God, an extension to the infinite and boundless; and says that God and man are one and the same in nature: let him be anathema.
