2543. The Potential Parts of Temperance.—The appetites of pleasure are the most difficult to restrain, and there is need of a perfect virtue like temperance to rule over them and keep them within the bounds of reason. The analogous or potential virtues of temperance are that one which is able to check, though it does not tame, the animal appetites (continency), and those that preside and rule over the less violent appetites for vengeance, exercise of authority, superior excellence, knowledge, amusement and display (meekness, etc.). See above, 2465 c.
2544. Continence.—(a) Its Nature.—This quality, as here taken, is the state of one who has not gained mastery over the passions sufficient to keep down strong, frequent and persistent rebellions, but whose will is firmly disposed to resist their attacks. It is less than a moral virtue, then, since it does not tranquillize the lower appetites. The temperate man has already subdued his passions, and hence he is less disturbed by them, or at least he has less trouble in rejecting their onsets.
(b) Its Relation to Temperance.—Greater difficulty increases merit, if it is due to the presence of a corporal or external impediment (e.g., a man of sickly constitution or one who suffers great opposition deserves more credit for his work than a man of vigorous constitution or one who enjoys great favors and opportunities); not, however, if it is due to the absence of a spiritual excellence (e.g., a man who finds work hard because he is lazy does not deserve more credit than another who finds it easy because he is industrious). Hence, temperance is more deserving than continence, for it controls passion with greater ease simply because it has subjected not only the higher but also the lower appetite to the dictates of reason.
(c) Its Opposite.—The vice opposed to continence is incontinence, which does not follow the dictate of reason to resist the onslaughts of passion; it sees and approves the higher things, but it follows the lower. This sin is less grievous than intemperance, just as a passing indisposition is less harmful than a settled malady. For passion comes and goes, and the incontinent man quickly regrets his weakness; but a sinful habit of gluttony or impurity is permanent, and is so like a second nature that its votaries rejoice when they have satisfied their desires (Prov., ii. 14). Incontinence in pleasure is more disgraceful than incontinence in anger, for anger is less distant from reason; but on the other hand the irascible man usually sins more grievously by the greater harm he does to others. It is more difficult to contain oneself from wrath than from intemperance in the sense that wrath storms the soul by a more vehement and compelling attack; yet, it is harder to be unconquered by pleasure, because it lays persistent siege to the soul and demands a more unwearied vigilance.
2545. Meekness.—Meekness or mildness is the virtue that moderates anger.
(a) It is a virtue, since it consists in moderation according to right reason. Our Lord proclaims it blessed (Matt., v. 4). and St. Paul numbers it among the Fruits of the Spirit (Gal., v. 23). Illustrious models of mildness are Joseph (Gen., l. 20), Moses (Num., xii. 3), David (I Kings, xxiv), Christ (Luke, xv; John, i. 29, viii. 11), St. Paul (Acts, xx. 31).
(b) Its office is moderation, and hence in its manner, though not in its matter, it is like temperance. It follows the middle way between the extremes of sinful indignation and sinful indulgence.
(c) Its matter is the passion of anger, that is, the sensitive appetite that inclines one to avenge an evil by punishing its author. Like other passions (121), anger is indifferent in itself, but it is made good or evil by its reasonableness or unreasonableness. The meek man is angry at times, but only when and where and as he should be (Ps. iv. 5); his anger is not a blind impulse, but a righteous zeal that attacks a wrong only after reason has shown that this is the proper course.
2546. Anger.—Anger is sinful when it deviates from reason, as to its matter or its manner.
(a) Thus, it is unreasonable as to its matter (i.e., its vengeance) when it punishes unjustifiably (e.g., when the person punished is innocent, when the penalty is excessive, when the legal order is not followed, when the motive is not justice or correction, but hatred, etc).
