But equality does not belong to the essence of an image; for as Augustine says (QQ. 83, qu. 74): "Where there is an image there is not necessarily equality," as we see in a person's image reflected in a glass. Yet this is of the essence of a perfect image; for in a perfect image nothing is wanting that is to be found in that of which it is a copy. Now it is manifest that in man there is some likeness to God, copied from God as from an exemplar; yet this likeness is not one of equality, for such an exemplar infinitely excels its copy. Therefore there is in man a likeness to God; not, indeed, a perfect likeness, but imperfect. And Scripture implies the same when it says that man was made "to" God's likeness; for the preposition "to" signifies a certain approach, as of something at a distance.
Reply Obj. 1: The Prophet speaks of bodily images made by man.
Therefore he says pointedly: "What image will you make for Him?" But
God made a spiritual image to Himself in man.
Reply Obj. 2: The First-Born of creatures is the perfect Image of God, reflecting perfectly that of which He is the Image, and so He is said to be the "Image," and never "to the image." But man is said to be both "image" by reason of the likeness; and "to the image" by reason of the imperfect likeness. And since the perfect likeness to God cannot be except in an identical nature, the Image of God exists in His first-born Son; as the image of the king is in his son, who is of the same nature as himself: whereas it exists in man as in an alien nature, as the image of the king is in a silver coin, as Augustine says explains in De decem Chordis (Serm. ix, al, xcvi, De Tempore).
Reply Obj. 3: As unity means absence of division, a species is said to be the same as far as it is one. Now a thing is said to be one not only numerically, specifically, or generically, but also according to a certain analogy or proportion. In this sense a creature is one with God, or like to Him; but when Hilary says "of a thing which adequately represents another," this is to be understood of a perfect image. _______________________
SECOND ARTICLE [I, Q. 93, Art. 2]
Whether the Image of God Is to Be Found in Irrational Creatures?
Objection 1: It would seem that the image of God is to be found in irrational creatures. For Dionysius says (Div. Nom. ii): "Effects are contingent images of their causes." But God is the cause not only of rational, but also of irrational creatures. Therefore the image of God is to be found in irrational creatures.
Obj. 2: Further, the more distinct a likeness is, the nearer it approaches to the nature of an image. But Dionysius says (Div. Nom. iv) that "the solar ray has a very great similitude to the Divine goodness." Therefore it is made to the image of God.
Obj. 3: Further, the more perfect anything is in goodness, the more it is like God. But the whole universe is more perfect in goodness than man; for though each individual thing is good, all things together are called "very good" (Gen. 1:31). Therefore the whole universe is to the image of God, and not only man.
Obj. 4: Further, Boethius (De Consol. iii) says of God: "Holding the world in His mind, and forming it into His image." Therefore the whole world is to the image of God, and not only the rational creature.
