Council of Ephesus, Cyril of Alexandria: Anathema II

If anyone shall 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 only Christ both God and man at the same time:  let him be anathema.

Edition and transmission

Cyril of Alexandria authored this text. The source editor discusses uncertainty about its formal approval at Ephesus and its subsequent conciliar reception. It is preserved as received doctrinal material, not as an undisputed text newly authored by the council.
