“Defining all this we likewise declare that in him are two natural wills and two natural operations indivisibly, inconvertibly, inseparably, inconfusedly, according to the teaching of the holy Fathers. And these two natural wills are not contrary the one to the other (God forbid!) as the impious heretics assert, but his human will follows and that not as resisting and reluctant, but rather as subject to his divine and omnipotent will. For it was right that the flesh should be moved but subject to the divine will, according to the most wise Athanasius. For as his flesh is called and is the flesh of God the Word, so also the natural will of his flesh is called and is the proper will of God the Word, as he himself says: “I came down from heaven, not that I might do mine own will but the will of the Father which sent me!” where he calls his own will the will of his flesh, inasmuch as his flesh was also his own. For as his most holy and immaculate animated flesh was not destroyed because it was deified but continued in its own state and nature, so also his human will, although deified, was not suppressed, but was rather preserved according to the saying of Gregory Theologus: “His will [that is, the Savior’s] is not contrary to God but altogether deified.”
We glorify two natural operations indivisibly, immutably, inconfusedly, inseparably in the same our Lord Jesus Christ our true God; that is to say a divine operation and a human operation, according to the divine preacher Leo, who most distinctly asserts as follows: “For each form does in communion with the other what pertains properly to it, the Word, namely, doing that which pertains to the Word, and the flesh that which pertains to the flesh.”
For we will not admit one natural operation in God and in the creature, as we will not exalt into the divine essence what is created, nor will we bring down the glory of the divine nature to the place suited to the creature.
We recognize the miracles and the sufferings as of one and the same [Person], but of one or of the other nature of which he is and in which he exists, as Cyril admirably says. Preserving therefore the inconfusedness and indivisibility, we make briefly this whole confession, believing our Lord Jesus Christ to be one of the Trinity and after the incarnation our true God, we say that his two natures shone forth in his one subsistence in which he both performed the miracles and endured the sufferings through the whole of his economic conversation, and that not in appearance only but in very deed, and this by reason of the difference of nature which must be recognized in the same Person, for although joined together yet each nature wills and does the things proper to it and that indivisibly and inconfusedly. Wherefore we confess two wills and two operations, concurring most fitly in him for the salvation of the human race.
These things, therefore, with all diligence and care having been formulated by us, we define that it be permitted to no one to bring forward, or to write, or to compose, or to think, or to teach a different faith. Whosoever shall presume to compose a different faith, or to propose, or teach, or hand to those wishing to be converted to the knowledge of the truth, from the Gentiles or Jews, or from any heresy, any different Creed; or to introduce a new voice or invention of speech to subvert these things which now have been determined by us, all these, if they be Bishops or clerics let them be deposed, the Bishops from the Episcopate, the clerics from the clergy; but if they be monks or laymen: let them be anathematized.”
