Council of Ephesus, Cyril of Alexandria: Anathema XI

Whosoever shall not confess that the flesh of the Lord giveth life and that it pertains to the Word of God the Father as his very own, but shall pretend that it belongs to another person who is united to him [i.e., the Word] only according to honour, and who has served as a dwelling for the divinity; and shall not rather confess, as we say, that that flesh giveth life because it is that of the Word who giveth life to all:  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.
