Council of Constantinople III, 680-681

of God, so also the natural will of His flesh is called and is the proper will of the Word of God as He Himself says: "Because I came down from heaven, not to do my own will but the will of my Father who sent me" [cf. John 6:38], calling the will of the flesh His own. For the body became His own. For as His most holy and immaculate animated flesh deified has not been destroyed but in its own status and plan remained, so also His human will deified has not been destroyed, but on the contrary it has been saved according to the theologian Gregory who says:¹ "For to wish of that one an entire deification, which is understood in the Savior, is not contrary to God."

292. But we glorify two natural operations indivisibly, inconvertibly, unfusedly, inseparably in our Lord Jesus Christ Himself, our true God, that is, the divine operation and the human operation, according to Leo the divine preacher who very clearly asserts: "For each form does what is proper to itself with the mutual participation of the other, that is, the Word doing what is of the Word and the flesh accomplishing what is of the flesh" [see n. 144]. For at no time shall we grant one natural operation to God and to the creature, so that neither what was created, we raise into divine essence, nor what is especially of divine nature, we cast down to a place begetting creatures. For of one and the same we recognize the miracles and the sufferings according to the one and the other of these natures from which He is and in which He has to be as the admirable Cyril says. Therefore we, maintaining completely an unconfused and undivided (opinion), in a brief statement set forth all: that we, believing that He is one of the Holy Trinity, our Lord Jesus Christ our true God, and after the incarnation assert that His two natures radiate in His one substance, in which His miracles and His sufferings through all His ordained life, not through phantasy but truly He has shown, on account of the natural difference which is recognized in the same single substance, while with the mutual participation of the other, each nature indivisibly and without confusion willed and performed its own works; according to this plan we confess two natural wills and operations concurring mutually in Him for the salvation of the human race.

293. These things, therefore, having been determined by us with all caution and diligence, we declare that no one is permitted to introduce, or to describe, or to compare, or to study, or otherwise to teach another faith. But whoever presumes to compare or to introduce or to teach or to pass on another creed to those wishing to turn from the belief of the Gentiles or of the Jews or from any heresy whatsoever to the acknowledgement of truth, or who (presumes) to introduce a novel doctrine or an invention of discourse to the subversion of those things which now have been determined by us, (we declare) these, whether they are bishops or clerics,
