" And when Paul discusses the restoration of the image, it is clear that we should infer from his words that man is made to conform to God, not by an inflowing of substance, but by the grace and power of the Spirit. For he says that by “beholding Christ’s glory, we are being transformed into his very image… as through the Spirit of the Lord” [II Cor. 3:18], who surely works in us without rendering us consubstantial with God.
