1474. Increase and decrease in gravity of scandal depends on the internal dispositions of the scandal-giver and the external influence he has on the person scandalized. (a) The internal factors on which the quantity of scandal depends are the amount of deliberation and the degree of intention. It is more serious to speak a scandalous word with premeditation than to speak it somewhat thoughtlessly; more scandalous to speak it when the hearer’s spiritual ruin is directly intended, than when that ruin is not directly intended. (b) The external factors on which the quantity of scandal depends are the amount of influence the bad example has and the character of the evil to which it leads. It is more serious to corrupt A, who would not otherwise have been corrupted, than to corrupt B, who would have been corrupted even without one’s bad example; it is more serious to cause another to commit mortal sin, than to cause him to commit venial sin.
1475. Persons Scandalized.—Is it possible to scandalize people who are firmly rooted in virtue?
(a) If the question be understood of scandal in a wide sense, even the perfect may be scandalized. They may be shocked and horrified at the evil example they witness; they may be hindered from performing the external good works they desire to accomplish (I Thess., ii. 18). But these things do not hinder them internally, or separate them from the love of God (Rom., viii. 38, 39).
(b) If the question be understood of possibility in an absolute sense, even the perfect may suffer real scandal, that is, they may be influenced to sin on account of the example witnessed. Since they are not confirmed in grace in this life, it is not repugnant that they commit sin and lose grace.
(c) If the question be understood of possibility in a relative sense—that is, if we consider what we should expect in view of the character of perfect men, and what does usually happen—the perfect cannot be scandalized, since they are so firmly united to God that the sayings or doings, no matter of whom, cannot cause them to sin (Ps. cxxiv. 1, 2), although they may at times be disturbed thereby (Ps. lxxii. 2).
1476. Is it possible that the perfect should give scandal?
(a) If the question be understood of absolute possibility, even the perfect may give scandal, since they are not immune from defect (I John, i. 8). (b) If the question be understood of relative possibility, as explained above, the perfect cannot scandalize, for their sins are mostly internal acts not entirely deliberate, while the external words or acts in which they fall short deviate so slightly from right as to offer no occasion of sinning to another. The perfect man is one who is on his guard, especially that he become not a stumbling-block to others, and it is therefore a rare exception when he causes scandal.
1477. Duty of Avoiding Scandal.—At times it is impossible to avoid giving scandal, unless one surrenders some spiritual or temporal good. Hence, on this point there are two questions to be considered: (a) When is one obliged to surrender spiritual goods for the sake of avoiding scandal? (b) When is one obliged to surrender temporal goods for the sake of avoiding scandal?
1478. The Surrender of Spiritual Goods in order to Avoid Scandal.—(a) Spiritual goods that are so necessary that one cannot give them up without committing sin may not be surrendered; for, according to the order of charity, one must be more solicitous to keep oneself from sin than to preserve others, and moreover a good end does not justify sinful means. Hence, it is not lawful to commit mortal or even venial sin to avoid giving scandal to another. Examples: One may not tone down the doctrine of right and wrong in order to keep another from blasphemy. One may not tell a slight lie to keep another from taking undeserved offense.
(b) Spiritual goods which can be put aside without sin are not to be neglected on account of malicious or Pharisaic scandal, as long as there is a good reason which calls for their use; for the person who takes malicious scandal from these spiritual things is in difficulty through his own fault and can rescue himself, and it is not reasonable that his malice should be permitted to impede the benefit of others. Thus, our Lord declared that no attention was to be given the scandal which the Pharisees took from His doctrine (Matt., xv. 14).
