If anyone will not confess that the Father, Son and holy Spirit have one nature or substance, that they have one power and authority, that there is a consubstantial Trinity, one Deity to be adored in three subsistences or persons: let him be anathema. There is only one God and Father, from whom all things come, and one Lord, Jesus Christ, through whom all things are, and one holy Spirit, in whom all things are.

If anyone will not confess that the Word of God has two nativities, that which is before all ages from the Father, outside time and without a body, and secondly that nativity of these latter days when the Word of God came down from the heavens and was made flesh of holy and glorious Mary, mother of God and ever-virgin, and was born from her: let him be anathema.

If anyone declares that the [Word] of God who works miracles is not identical with the Christ who suffered, or alleges that God the Word was with the Christ who was born of woman, or was in him in the way that one might be in another, but that our lord Jesus Christ was not one and the same, the Word of God incarnate and made man, and that the miracles and the sufferings which he voluntarily underwent in the flesh were not of the same person: let him be anathema.

If anyone declares that it was only in respect of grace, or of principle of action, or of dignity or in respect of equality of honour, or in respect of authority, or of some relation, or of some affection or power that there was a unity made between the Word of God and the man, or if anyone alleges that it is in respect of good will, as if God the Word was pleased with the man, because he was well and properly disposed to God, as Theodore claims in his madness; or if anyone says that this union is only a sort of synonymity, as the Nestorians allege, who call the Word of God Jesus and Christ, and even designate the human separately by the names "Christ" and "Son", discussing quite obviously two different persons, and only pretending to speak of one person and one Christ when the reference is to his title, honour, dignity or adoration; finally if anyone does not accept the teaching of the holy fathers that the union occurred of the Word of God with human flesh which is possessed by a rational and intellectual soul, and that this union is by synthesis or by person, and that therefore there is only one person, namely the lord Jesus Christ, one member of the holy Trinity: let him be anathema. The notion of "union" can be understood in many different ways. The supporters of the wickedness of Apollinarius and Eutyches have asserted that the union is produced by a confusing of the uniting elements, as they advocate the disappearance of the elements that unite. Those who follow Theodore and Nestorius, rejoicing in the division, have brought in a union which is only by affection. The holy church of God, rejecting the wickedness of both sorts of heresy, states her belief in a union between the Word of God and human flesh which is by synthesis, that is by a union of subsistence. In the mystery of Christ the union of synthesis not only conserves without confusing the elements that come together but also allows no division.

If anyone understands by the single subsistence of our lord Jesus Christ that it covers the meaning of many subsistences, and by this argument tries to introduce into the mystery of Christ two subsistences or two persons, and having brought in two persons then talks of one person only in respect of dignity, honour or adoration, as both Theodore and Nestorius have written in their madness; if anyone falsely represents the holy synod of Chalcedon, making out that it accepted this heretical view by its terminology of "one subsistence", and if he does not acknowledge that the Word of God is united with human flesh by subsistence, and that on account of this there is only one subsistence or one person, and that the holy synod of Chalcedon thus made a formal statement of belief in the single subsistence of our lord Jesus Christ: let him be anathema. There has been no addition of person or subsistence to the holy Trinity even after one of its members, God the Word, becoming human flesh.

If anyone declares that it can be only inexactly and not truly said that the holy and glorious ever-virgin Mary is the mother of God, or says that she is so only in some relative way, considering that she bore a mere man and that God the Word was not made into human flesh in her, holding rather that the nativity of a man from her was referred, as they say, to God the Word as he was with the man who came into being; if anyone misrepresents the holy synod of Chalcedon, alleging that it claimed that the virgin was the mother of God only according to that heretical understanding which the blasphemous Theodore put forward; or if anyone says that she is the mother of a man or the Christ-bearer, that is the mother of Christ, suggesting that Christ is not God; and does not formally confess that she is properly and truly the mother of God, because he who before all ages was born of the Father, God the Word, has been made into human flesh in these latter days and has been born to her, and it was in this religious understanding that the holy synod of Chalcedon formally stated its belief that she was the mother of God: let him be anathema.

If anyone, when speaking about the two natures, does not confess a belief in our one lord Jesus Christ, understood in both his divinity and his humanity, so as by this to signify a difference of natures of which an ineffable union has been made without confusion, in which neither the nature of the Word was changed into the nature of human flesh, nor was the nature of human flesh changed into that of the Word (each remained what it was by nature, even after the union, as this had been made in respect of subsistence); and if anyone understands the two natures in the mystery of Christ in the sense of a division into parts, or if he expresses his belief in the plural natures in the same lord Jesus Christ, God the Word made flesh, but does not consider the difference of those natures, of which he is composed, to be only in the onlooker's mind, a difference which is not compromised by the union (for he is one from both and the two exist through the one) but uses the plurality to suggest that each nature is possessed separately and has a subsistence of its own: let him be anathema.

If anyone confesses a belief that a union has been made out of the two natures divinity and humanity, or speaks about the one nature of God the Word made flesh, but does not understand these things according to what the fathers have taught, namely that from the divine and human natures a union was made according to subsistence, and that one Christ was formed, and from these expressions tries to introduce one nature or substance made of the deity and human flesh of Christ: let him be anathema. In saying that it was in respect of subsistence that the only-begotten God the Word was united, we are not alleging that there was a confusion made of each of the natures into one another, but rather that each of the two remained what it was, and in this way we understand that the Word was united to human flesh.

If anyone says that Christ is to be worshipped in his two natures, and by that wishes to introduce two adorations, a separate one for God the Word and another for the man; or if anyone, so as to remove the human flesh or to mix up the divinity and the humanity, monstrously invents one nature or substance brought together from the two, and so worships Christ, but not by a single adoration God the Word in human flesh along with his human flesh, as has been the tradition of the church from the beginning: let him be anathema.

If anyone does not confess his belief that our lord Jesus Christ, who was crucified in his human flesh, is truly God and the Lord of glory and one of the members of the holy Trinity: let him be anathema.

If anyone does not anathematize Arius, Eunomius, Macedonius, Apollinarius Nestorius, Eutyches and Origen, as well as their heretical books, and also all other heretics who have already been condemned and anathematized by the holy, catholic and apostolic church and by the four holy synods which have already been mentioned, and also all those who have thought or now think in the same way as the aforesaid heretics and who persist in their error even to death: let him be anathema.

If anyone defends the heretical Theodore of Mopsuestia, who said that God the Word is one, while quite another is Christ, who was troubled by the passions of the soul and the desires of human flesh, was gradually separated from that which is inferior, and became better by his progress in good works, and could not be faulted in his way of life, and as a mere man was baptized in the name of the Father and the Son and the holy Spirit, and through this baptism received the grace of the holy Spirit and came to deserve sonship and to be adored, in the way that one adores a statue of the emperor, as if he were God the Word, and that he became after his resurrection immutable in his thoughts and entirely without sin. Furthermore this heretical Theodore claimed that the union of God the Word to Christ is rather like that which, according to the teaching of the Apostle, is between a man and his wife: The two shall become one. Among innumerable other blasphemies he dared to allege that, when after his resurrection the Lord breathed on his disciples and said, Receive the holy Spirit, he was not truly giving them the holy Spirit, but he breathed on them only as a sign. Similarly he claimed that Thomas's profession of faith made when, after his resurrection, he touched the hands and side of the Lord, namely My Lord and my God, was not said about Christ, but that Thomas was in this way extolling God for raising up Christ and expressing his astonishment at the miracle of the resurrection.

This Theodore makes a comparison which is even worse than this when, writing about the acts of the Apostles, he says that Christ was like Plato, Manichaeus, Epicurus and Marcion, alleging that just as each of these men arrived at his own teaching and then had his disciples called after him Platonists, Manichaeans, Epicureans and Marcionites, so Christ found his teaching and then had disciples who were called Christians. If anyone offers a defence for this more heretical Theodore, and his heretical books in which he throws up the aforesaid blasphemies and many other additional blasphemies against our great God and saviour Jesus Christ, and if anyone fails to anathematize him and his heretical books as well as all those who offer acceptance or defence to him, or who allege that his interpretation is correct, or who write on his behalf or on that of his heretical teachings, or who are or have been of the same way of thinking and persist until death in this error: let him be anathema.

If anyone defends the heretical writings of Theodoret which were composed against the true faith, against the first holy synod of Ephesus and against holy Cyril and his Twelve Chapters, and also defends what Theodoret wrote to support the heretical Theodore and Nestorius and others who think in the same way as the aforesaid Theodore and Nestorius and accept them or their heresy and if anyone, because of them, shall accuse of being heretical the doctors of the church who have stated their belief in the union according to subsistence of God the Word; and if anyone does not anathematize these heretical books and those who have thought or now think in this way, and all those who have written against the true faith or against holy Cyril and his twelve chapters, and who persist in such heresy until they die: let him be anathema.

If anyone defends the letter which Ibas is said to have written to Mari the Persian, which denies that God the Word, who became incarnate of Mary the holy mother of God and ever virgin, became man, but alleges that he was only a man born to her, whom it describes as a temple, as if God the Word was one and the man someone quite different; which condemns holy Cyril as if he were a heretic, when he gives the true teaching of Christians, and accuses holy Cyril of writing opinions like those of the heretical Apollinarius ;which rebukes the first holy synod of Ephesus, alleging that it condemned Nestorius without going into the matter by a formal examination; which claims that the twelve chapters of holy Cyril are heretical and opposed to the true faith; and which defends Theodore and Nestorius and their heretical teachings and books. If anyone defends the said letter and does not anathematize it and all those who offer a defence for it and allege that it or a part of it is correct, or if anyone defends those who have written or shall write in support of it or the heresies contained in it, or supports those who are bold enough to defend it or its heresies in the name of the holy fathers of the holy synod of Chalcedon, and persists in these errors until his death: let him be anathema.

Such then are the assertions we confess. We have received them

• from holy Scripture,
• from the teaching of the holy fathers,
• and from the definitions about the one and the same faith made by the aforesaid four holy synods.
