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.
