Reply Obj. 2: Boasting is reckoned a species of lying, as regards the outward act whereby a man falsely ascribes to himself what he has not: but as regards the inward arrogance of the heart it is reckoned by Gregory to be a species of pride.
Reply Obj. 3: The ungrateful man ascribes to himself what he has from another: wherefore the first two species of pride pertain to ingratitude. To excuse oneself of a sin one has committed, belongs to the third species, since by so doing a man ascribes to himself the good of innocence which he has not. To aim presumptuously at what is above one, would seem to belong chiefly to the fourth species, which consists in wishing to be preferred to others.
Reply Obj. 4: The three mentioned by Anselm correspond to the progress of any particular sin: for it begins by being conceived in thought, then is uttered in word, and thirdly is accomplished in deed.
The twelve degrees mentioned by Bernard are reckoned by way of opposition to the twelve degrees of humility, of which we have spoken above (Q. 161, A. 6). For the first degree of humility is to "be humble in heart, and to show it in one's very person, one's eyes fixed on the ground": and to this is opposed "curiosity," which consists in looking around in all directions curiously and inordinately. The second degree of humility is "to speak few and sensible words, and not to be loud of voice": to this is opposed "frivolity of mind," by which a man is proud of speech. The third degree of humility is "not to be easily moved and disposed to laughter," to which is opposed "senseless mirth." The fourth degree of humility is "to maintain silence until one is asked," to which is opposed "boasting". The fifth degree of humility is "to do nothing but to what one is exhorted by the common rule of the monastery," to which is opposed "singularity," whereby a man wishes to seem more holy than others. The sixth degree of humility is "to believe and acknowledge oneself viler than all," to which is opposed "arrogance," whereby a man sets himself above others. The seventh degree of humility is "to think oneself worthless and unprofitable for all purposes," to which is opposed "presumption," whereby a man thinks himself capable of things that are above him. The eighth degree of humility is "to confess one's sins," to which is opposed "defense of one's sins." The ninth degree is "to embrace patience by obeying under difficult and contrary circumstances," to which is opposed "deceitful confession," whereby a man being unwilling to be punished for his sins confesses them deceitfully. The tenth degree of humility is "obedience," to which is opposed "rebelliousness." The eleventh degree of humility is "not to delight in fulfilling one's own desires"; to this is opposed "license," whereby a man delights in doing freely whatever he will. The last degree of humility is "fear of God": to this is opposed "the habit of sinning," which implies contempt of God.
In these twelve degrees not only are the species of pride indicated, but also certain things that precede and follow them, as we have stated above with regard to humility (Q. 161, A. 6). _______________________
FIFTH ARTICLE [II-II, Q. 162, Art. 5]
Whether Pride Is a Mortal Sin?
Objection 1: It would seem that pride is not a mortal sin. For a gloss on Ps. 7:4, "O Lord my God, if I have done this thing," says: "Namely, the universal sin which is pride." Therefore if pride were a mortal sin, so would every sin be.
Obj. 2: Further, every mortal sin is contrary to charity. But pride is apparently not contrary to charity, neither as to the love of God, nor as to the love of one's neighbor, because the excellence which, by pride, one desires inordinately, is not always opposed to God's honor, or our neighbor's good. Therefore pride is not a mortal sin.
Obj. 3: Further, every mortal sin is opposed to virtue. But pride is not opposed to virtue; on the contrary, it arises therefrom, for as Gregory says (Moral. xxxiv, 23), "sometimes a man is elated by sublime and heavenly virtues." Therefore pride is not a mortal sin.
