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.
It must, however, be observed that the proper object of the appetite is a thing not possessed. Now spiritual good, in so far as the rational creature participates in the Divine likeness, may be considered in reference to three things. First, as to natural being: and this likeness was imprinted from the very outset of their creation, both on man---of whom it is written ( Gn. 1:26 ) that God made man "to His image and likeness"---and on the angel, of whom it is written ( Ezech. 28:12 ): "Thou wast the seal of resemblance." Secondly, as to knowledge: and this likeness was bestowed on the angel at his creation, wherefore immediately after the words just quoted, "Thou wast the seal of resemblance," we read: "Full of wisdom." But the first man, at his creation, had not yet received this likeness actually but only in potentiality. Thirdly, as to the power of operation: and neither angel nor man received this likeness actually at the very outset of his creation, because to each there remained something to be done whereby to obtain happiness.
Accordingly, while both (namely the devil and the first man) coveted God's likeness inordinately, neither of them sinned by coveting a likeness of nature. But the first man sinned chiefly by coveting God's likeness as regards "knowledge of good and evil," according to the serpent's instigation, namely that by his own natural power he might decide what was good, and what was evil for him to do; or again that he should of himself foreknow what good and what evil would befall him. Secondarily he sinned by coveting God's likeness as regards his own power of operation, namely that by his own natural power he might act so as to obtain happiness. Hence Augustine says (Gen. ad lit. xi, 30) that "the woman's mind was filled with love of her own power." On the other hand, the devil sinned by coveting God's likeness, as regards power. Wherefore Augustine says (De Vera Relig. 13) that "he wished to enjoy his own power rather than God's." Nevertheless both coveted somewhat to be equal to God, in so far as each wished to rely on himself in contempt of the order of the Divine rule.
Reply to Objection 1: This argument considers the likeness of nature: and man did not sin by coveting this, as stated.
Reply to Objection 2: It is not a sin to covet God's likeness as to knowledge, absolutely; but to covet this likeness inordinately, that is, above one's measure, this is a sin. Hence Augustine commenting on Ps. 70:18, "O God, who is like Thee?" says: "He who desires to be of himself, even as God is of no one, wishes wickedly to be like God. Thus did the devil, who was unwilling to be subject to Him, and man who refused to be, as a servant, bound by His command."
Reply to Objection 3: This argument considers the likeness of equality.
Whether the sin of our first parents was more grievous than other sins?
Objection 1: It would seem that the sin of our first parents was more grievous than other sins. For Augustine says (De Civ. Dei xiv, 15): "Great was the wickedness in sinning, when it was so easy to avoid sin." Now it was very easy for our first parents to avoid sin, because they had nothing within them urging them to sin. Therefore the sin of our first parents was more grievous than other sins.
Objection 2: Further, punishment is proportionate to guilt. Now the sin of our first parents was most severely punished, since by it "death entered into this world," as the Apostle says ( Rom. 5:12 ). Therefore that sin was more grievous than other sins.
Objection 3: Further, the first in every genus is seemingly the greatest (Metaph. ii, 4 [*Ed. Diel. i, 1]). Now the sin of our first parents was the first among sins of men. Therefore it was the greatest.
On the contrary, Origen says [*Peri Archon i, 3]: "I think that a man who stands on the highest step of perfection cannot fail or fall suddenly: this can happen only by degrees and little by little." Now our first parents were established on the highest and perfect grade. Therefore their first sin was not the greatest of all sins.
I answer that, There is a twofold gravity to be observed in sin. one results from the very species of the sin: thus we say that adultery is a graver sin than simple fornication. The other gravity of sin results from some circumstance of place, person, or time. The former gravity is more essential to sin and is of greater moment: hence a sin is said to be grave in respect of this gravity rather than of the other. Accordingly we must say that the first man's sin was not graver than all other sins of men, as regards the species of the sin. For though pride, of its genus, has a certain pre-eminence over other sins, yet the pride whereby one denies or blasphemes God is greater than the pride whereby one covets God's likeness inordinately, such as the pride of our first parents, as stated (A[2]).
But if we consider the circumstances of the persons who sinned, that sin was most grave on account of the perfection of their state. We must accordingly conclude that this sin was most grievous relatively but not simply.
Reply to Objection 1: This argument considers the gravity of sin as resulting from the person of the sinner.
Reply to Objection 2: The severity of the punishment awarded to that first sin corresponds to the magnitude of the sin, not as regards its species but as regards its being the first sin: because it destroyed the innocence of our original state, and by robbing it of innocence brought disorder upon the whole human nature.
Reply to Objection 3: Where things are directly subordinate, the first must needs be the greatest. Such is not the order among sins, for one follows from another accidentally. And thus it does not follow that the first sin is the greatest.
Whether Adam's sin was more grievous than Eve's?
Objection 1: It would seem that Adam's sin was more grievous than Eve's. For it is written ( 1 Tim. 2:14 ): "Adam was not seduced, but the woman being seduced was in the transgression": and so it would seem that the woman sinned through ignorance, but the man through assured knowledge. Now the latter is the graver sin, according to Luke 12:47 , 48 "That servant who knew the will of his lord . . . and did not according to his will, shall be beaten with many stripes: but he that knew not, and did things worthy of stripes, shall be beaten with few stripes." Therefore Adam's sin was more grievous than Eve's.
Objection 2: Further, Augustine says (De Decem Chordis 3 [*Serm. ix; xcvi de Temp.]): "If the man is the head, he should live better, and give an example of good deeds to his wife, that she may imitate him." Now he who ought to do better, sins more grievously, if he commit a sin. Therefore Adam sinned more grievously than Eve.
Objection 3: Further, the sin against the Holy Ghost would seem to be the most grievous. Now Adam, apparently, sinned against the Holy Ghost, because while sinning he relied on God's mercy [*Cf. Q[21], A[2], OBJ[3]. St. Thomas is evidently alluding to the words of Peter Lombard quoted there], and this pertains to the sin of presumption. Therefore it seems that Adam sinned more grievously than Eve.
On the contrary, Punishment corresponds to guilt. Now the woman was more grievously punished than the man, as appears from Gn. 3 . Therefore she sinned more grievously than the man.
I answer that, As stated (A[3]), the gravity of a sin depends on the species rather than on a circumstance of that sin. Accordingly we must assert that, if we consider the condition attaching to these persons, the man's sin is the more grievous, because he was more perfect than the woman.
As regards the genus itself of the sin, the sin of each is considered to be equal, for each sinned by pride. Hence Augustine says (Gen. ad lit. xi, 35): "Eve in excusing herself betrays disparity of sex, though parity of pride."
But as regards the species of pride, the woman sinned more grievously, for three reasons. First, because she was more puffed up than the man. For the woman believed in the serpent's persuasive words, namely that God had forbidden them to eat of the tree, lest they should become like to Him; so that in wishing to attain to God's likeness by eating of the forbidden fruit, her pride rose to the height of desiring to obtain something against God's will. On the other hand, the man did not believe this to be true; wherefore he did not wish to attain to God's likeness against God's will: but his pride consisted in wishing to attain thereto by his own power. Secondly, the woman not only herself sinned, but suggested sin to the man; wherefore she sinned against both God and her neighbor. Thirdly, the man's sin was diminished by the fact that, as Augustine says (Gen. ad lit. xi, 42), "he consented to the sin out of a certain friendly good-will, on account of which a man sometimes will offend God rather than make an enemy of his friend. That he ought not to have done so is shown by the just issue of the Divine sentence."
It is therefore evident that the woman's sin was more grievous than the man's.
