Council of Ephesus, Cyril of Alexandria: Anathema VIII

If anyone shall dare to say that the assumed man (ἀναληφθέντα ) ought to be worshipped together with God the Word, and glorified together with him, and recognised together with him as God, and yet as two different things, the one with the other (for this “Together with” is added [i.e., by the Nestorians] to convey this meaning); and shall not rather with one adoration worship the Emmanuel and pay to him one glorification, as [it is written] “The Word was made flesh”:  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.
