Thus, therefore, we confess that the nature of the Godhead is wholly and perfectly in each of its subsistences, wholly in the Father, wholly in the Son, and wholly in the Holy Spirit. Wherefore also the Father is perfect God, the Son is perfect God, and the Holy Spirit is perfect God. In like manner, too, in the Incarnation of the Trinity of the One God the Word of the Holy Trinity, we hold that in one of its subsistences the nature of the Godhead is wholly and perfectly united with the whole nature of humanity, and not part united to part Against Arius, Apollinaris, and the Severians.. The divine Apostle in truth says that in Him dwelleth all the fulness of the Godhead bodily Col. ii. 9., that is to say in His flesh. And His divinely-inspired disciple, Dionysius, who had so deep a knowledge of things divine, said that the Godhead as a whole had fellowship with us in one of its own subsistences Dion., De div. nom., ch. 2.. But we shall not be driven to hold that all the subsistences of the Holy Godhead, to wit the three, are made one in subsistence with all the subsistences of humanity. For in no other respect did the Father and the Holy Spirit take part in the incarnation of God the Word than according to good will and pleasure. But we hold that to the whole of human nature the whole essence of the Godhead was united. For God the Word omitted none of the things which He implanted in our nature when He formed us in the beginning, but took them all upon Himself, body and soul both intelligent and rational, and all their properties. For the creature that is devoid of one of these is not man. But He in His fulness took upon Himself me in my fulness, and was united whole to whole that He might in His grace bestow salvation on the whole man. For what has not been taken cannot be healed Athan., De salut. adv. Christ: Greg. Naz., Epist. 1 ad Cled. et Orat. 1: Cyril, in John viii..
