Reply Obj. 4: According to Augustine (Gen. ad lit. xi, 30), "the woman had not believed the serpent's statement that they were debarred by God from a good and useful thing, were her mind not already filled with the love of her own power, and a certain proud self-presumption." This does not mean that pride preceded the promptings of the serpent, but that as soon as the serpent had spoken his words of persuasion, her mind was puffed up, the result being that she believed the demon to have spoken truly. _______________________
SECOND ARTICLE [II-II, Q. 163, Art. 2]
Whether the First Man's Pride Consisted in His Coveting God's Likeness?
Objection 1: It would seem that the first man's pride did not consist in his coveting the Divine likeness. For no one sins by coveting that which is competent to him according to his nature. Now God's likeness is competent to man according to his nature: for it is written (Gen. 1:26): "Let us make man to our image and likeness." Therefore he did not sin by coveting God's likeness.
Obj. 2: Further, it would seem that man coveted God's likeness in order that he might obtain knowledge of good and evil: for this was the serpent's suggestion: "You shall be as Gods knowing good and evil." Now the desire of knowledge is natural to man, according to the saying of the Philosopher at the beginning of his Metaphysics i, 1: "All men naturally desire knowledge." Therefore he did not sin by coveting God's likeness.
Obj. 3: Further, no wise man chooses the impossible. Now the first man was endowed with wisdom, according to Ecclus. 17:5, "He filled them with the knowledge of understanding." Since then every sin consists in a deliberate act of the appetite, namely choice, it would seem that the first man did not sin by coveting something impossible. But it is impossible for man to be like God, according to the saying of Ex. 15:11, "Who is like to Thee among the strong, O Lord?" Therefore the first man did not sin by coveting God's likeness.
On the contrary, Augustine commenting on Ps. 68:5 [*Enarr. in Ps. 68], "Then did I restore [Douay: 'pay'] that which I took not away," says: "Adam and Eve wished to rob the Godhead and they lost happiness."
I answer that, likeness is twofold. One is a likeness of absolute equality [*Cf. I, Q. 93, A. 1]: and such a likeness to God our first parents did not covet, since such a likeness to God is not conceivable to the mind, especially of a wise man.
The other is a likeness of imitation, such as is possible for a creature in reference to God, in so far as the creature participates somewhat of God's likeness according to its measure. For Dionysius says (Div. Nom. ix): "The same things are like and unlike to God; like, according as they imitate Him, as far as He can be imitated; unlike, according as an effect falls short of its cause." Now every good existing in a creature is a participated likeness of the first good.
Wherefore from the very fact that man coveted a spiritual good above his measure, as stated in the foregoing Article, it follows that he coveted God's likeness inordinately.
