FIRST ARTICLE [I, Q. 93, Art. 1]
Whether the Image of God Is in Man?
Objection 1: It would seem that the image of God is not in man. For it is written (Isa. 40:18): "To whom have you likened God? or what image will you make for Him?"
Obj. 2: Further, to be the image of God is the property of the
First-Begotten, of Whom the Apostle says (Col. 1:15): "Who is the
image of the invisible God, the First-Born of every creature."
Therefore the image of God is not to be found in man.
Obj. 3: Further, Hilary says (De Synod [*Super i can]. Synod. Ancyr.) that "an image is of the same species as that which it represents"; and he also says that "an image is the undivided and united likeness of one thing adequately representing another." But there is no species common to both God and man; nor can there be a comparison of equality between God and man. Therefore there can be no image of God in man.
On the contrary, It is written (Gen. 1:26): "Let Us make man to Our own image and likeness."
I answer that, As Augustine says (QQ. 83, qu. 74): "Where an image exists, there forthwith is likeness; but where there is likeness, there is not necessarily an image." Hence it is clear that likeness is essential to an image; and that an image adds something to likeness—namely, that it is copied from something else. For an "image" is so called because it is produced as an imitation of something else; wherefore, for instance, an egg, however much like and equal to another egg, is not called an image of the other egg, because it is not copied from it.
