Canons of The Council at Ephesus
1 If anyone says that the Emmanuel is true God, and not rather God with us, that is, that he has united himself to a like nature with ours, which he assumed from the Virgin Mary, and dwelt in it; and if anyone calls Mary the mother of God the Word, and not rather mother of him who is Emmanuel; and if he maintains that God the Word has changed himself into the flesh, which he only assumed in order to make his Godhead visible, and to be found in form as a man, let him be anathema.
1 If any one asserts that, at the union of the Logos 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 it has been partially united with the flesh; or ascribes to the flesh, by reason of its reception of 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.
1 If anyone shall after the [hypostatic] union divide the hypostasis in the one Christ, joining them by that connection alone, which happens according to worthiness, or even authority and power, and not rather by a coming together, which is made by natural union, let him be anathema.
1 If any one assigns the expressions of the Gospels and Apostolic letters, which refer to the two natures of Christ, to one only of those natures, and even ascribes suffering to the divine Word, both in the flesh and in the Godhead; let him be anathema.
1 If any one ventures to say that, even after the assumption of human nature, there is only one Son of God, namely, he who is so in nature (naturaliter filius=Logos), while he (Since the assumption of the flesh) is certainly Emmanuel; let him be anathema.
1 If anyone, after the Incarnation calls another than Christ the Word, and ventures to say that the form of a servant is equally with the Word of God, without beginning and uncreated, and not rather that it is made by him as its natural Lord and Creator and God, and that he has promised to raise it again in the words: "Destroy this temple, and in three days I will build it up again"; let him be anathema.
1 If any one says that the man who was formed of the Virgin is the Only-begotten, who was born from the bosom of the Father, before the morning star was, and does not rather confess that he has obtained the designation of Only-begotten on account of his connection with him who in nature is the Only-begotten of the Father; and besides, if any one calls another than the Emmanuel Christ let him be anathema.
1 If anyone shall dare to say that the assumed man ought to be worshipped together with God the Word, and glorified together with him, and recognized 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.
1 If anyone says that the form of a servant is of like nature with the Holy Spirit, and not rather that it owes its union with the Word which has existed since the conception, to his mediation, by which it works miraculous healings among men, and possesses the power of expelling demons; let him be anathema.
