1 Wherefore, as we confess Him to have two natures, that is Godhead and Manhood, neither confounded, nor divided, nor interchanged; so the rule of piety teaches us that He, one and the same, our Lord Jesus Christ, had also two natural wills and two natural operations, as being perfect God and perfect man.' Epistola Agathonis et Romanæ Synodi ad Concil. CEcum. VI.
2 And that in Him were two natural wills or volitions, and two natural operations without division, or change, or separation, or confusion, .... and two natural wills not contrary, God forbid, as impious heretics have said, but His human will subjected to His Divine and Almighty Will without resistance or reluctance. For the will of the flesh must needs be moved and subjected to His Divine will, according to the doctrine of Athanasius, who was most wise: for as His flesh is called and is the flesh of God, so also the natural will of His flesh is called and is the will of God, according to His own declaration, came down from heaven, not that I should do My own will, but the will of Him that sent Me," that is, the Father. He called the will of the flesh His own Will, as also His flesh became His own; for as the most holy and spotless and living flesh being deified was not destroyed, but remained in its own state and kind, so also His human will being deified was not destroyed, but was rather preserved, according to the saying of Gregory Theologus: "For His will, which is understood, in the Saviour is not contrary to God, but is wholly deified. We adore also two natural operations without division, without change, without separation,* without confusion in Him our Lord Jesus Christ, our true God, that is, the divine operation and the human operation; as the divine teacher Leo most clearly asserted, for each nature wrought that which was proper to itself in union with the other; the Word, that is, operating that which is of the Word, and the body accomplishing that which is of the body."
