(c) indirect or direct, according as the means employed to drive away a temptation are flight or attack. Examples: One who is disturbed by thoughts of hatred, resists them indirectly if he goes to the opera in order to be calmed by music, while he resists them directly, if he reads prayerfully I Cor. xiii, in order to become more charitable;
(d) virtual or actual, according as the act of dissent made, and not retracted, is adverted to or not. Examples: If a man rejects a temptation of envy as soon as he notices it, and repeats this act of rejection until the temptation has disappeared, his resistance is actual; if he rejects the temptation once for all as soon as it appears, but is not able to think of this purpose at each instant, his resistance was actual at the beginning, but virtual afterwards.
256. General rules regarding resistance to temptation: (a) it is a grave sin not to resist temptation, when the sin suggested is grave, the danger of consent serious, and the negligence considerable; otherwise the sin is venial; (b) negligence is considerable when the resistance used is not at all in proportion to the temptation. Example: If a man were suddenly to advert to the fact that a shrewd plan he had decided on was gravely unjust, he would be seriously negligent if he put off recalling the decision till he had dwelt more fully on its appealing features.
257. The kind of resistance to be opposed to temptation depends on the character and urgency of the temptation and the disposition of the person tempted. (a) Generally speaking, the more serious the temptation, the stronger should be the resistance. Example: One who knows from experience that temptations to hatred overcome him, if he uses only internal resistance, should make use of external resistance also. (b) In those cases in which the violence of the temptation increases in proportion to the strength of the resistance, it is better that the resistance be internal, indirect, etc. Examples: Temptations against faith are often overcome more readily by turning the mind away from the doubts suggested to other matters. Temptations that last a long time may be conquered more easily by despising them than by worrying about them and renewing protest after protest. The same is true as regards temptations against purity.
258. Danger of sin is the likelihood that it will be committed in certain circumstances. It is of two kinds, proximate and remote. (a) Danger of sin is proximate, when there is moral certainty that in given circumstances sin will be committed, either because the generality of mankind falls in such cases (absolute danger), or because in them a particular individual has always fallen (relative danger). Examples: Associating with depraved persons is a proximate danger of sin for anyone, since it is a matter of universal experience that evil associations corrupt good morals. Taking strong drink is a proximate danger for one who has never imbibed moderately in the past. (b) Danger of sin is remote, when the likelihood that sin will be committed is not morally certain, and does not exclude a serious and well-founded probability or expectation to the contrary. Example: There is remote danger in an occasional drink, if a person who had several times relapsed into intemperance, has practised abstemiousness for years.
259. Possibility of sin is the conceivability but unlikelihood that it will result from a certain set of circumstances. Example: Attention to business sometimes makes a man avaricious, practices of piety may degenerate into hypocrisy, etc., but there is no natural connection between industry and devotion, on the one hand, and greed and insincerity, on the other hand. Sin follows naturally from its danger, but only accidentally from its possibility.
260. It is not lawful imprudently to expose oneself to the danger of sin, since it is manifestly against reason to risk spiritual loss without cause. The character of the sin of him who does this differs according to circumstances. (a) He who rashly exposes himself to the proximate danger of grave sin, or to what he foresees will become proximate danger, is guilty of grave sin and of the species of sin to which he exposes himself—and this even though the sin does not actually follow. For to love what is so closely related to the sin is to love the sin itself. (b) He who rashly exposes himself to the remote danger of grave sin or to the proximate danger of venial sin is venially guilty. For, while such action is unreasonable, it does not imply affection for grave sin.
261. It is lawful to expose oneself to the danger of sin, if this can be done according to the laws of prudence, for otherwise absurdities would follow (e.g., that urgent duties should not be performed, if one feared they contained the danger of sin). The requirements of prudence referred to are: (a) that the one who exposes himself to the danger of sin be sure that his motive is good (viz., that he firmly intends to avoid the sin to which he may be tempted and to accomplish only the good he desires); (b) that the action he performs and which involves the danger is necessary, and bears a correspondence in importance to the gravity of the sin and the proximity of the risk; (c) that means be employed (e.g., prayer, pious thoughts, spiritual reading, and the use of the Sacraments), which will so reduce the danger that one has confident assurance that the danger will be encountered safely.
262. It is lawful to expose oneself to the possibility of sin, for, since almost every action may be perverted, one who wished to avoid the possibility of sin would have to leave this world and become confirmed in grace.
263. The Occasions of Sin are external circumstances—persons, places or things—which tempt one to sin. Examples: Persons who invite others to defraud and show how it can be accomplished, theatres where irreligious plays are staged, books that aim to depreciate virtue, etc.
