The Dogmatician: The Son of God vs. Sons of God

This, in turn, applies also to man. Like the Son, so also man as such is altogether the image of God. He does not just bear but is the image of God. There is this difference, of course, that what the Son is in an absolute sense, man is in only a relative sense. The former is the eternal only begotten Son; the latter is the created son of God. The former is the image of God within the divine being, the latter outside of it. The one is the image of God in a divine manner, the other is that in a creaturely manner. —Herman Bavinck, Reformed Dogmatics
