We were made as human beings in order to know and live full union with God: deification through uncreated grace. Our redemption through Christ can never be conceived separately from the ultimate goal of the totality of our deification, for “God became Himself man, that man might become God” (Irenaeus of Lyon, Adversus haereses V, preface; P.G. 7, col. 1120).
As Lossky (1974) said, “The Son has become like us by the incarnation; we become like Him by deification, by partaking of the divinity in the Holy Spirit, who communicates the divinity to each human person in a particular way. The redeeming work of the Son is related to our nature. The deifying work of the Holy Spirit concerns our persons” (In the image and likeness of God, p. 109).
