(d) Scandal is an occasion of a fall into sin, that is, it sets an example of sin before the attention, and thus suggests to the will that the will imitate the sin. Scandal is not, however, the cause of sin, for a person causes his own sin in yielding consent to the suggestion offered by scandal.

(e) Scandal is to another. A person may be said to scandalize himself in the sense that by his looks or acts he puts himself in an occasion of sin (Matt., v. 29, 30), or inasmuch as he maliciously makes the acts of a virtuous neighbor an occasion of sin; but scandal is more properly understood of an occasion of sin prepared for one’s neighbor.

1448. Causes of Scandal.—There are various divisions of scandal according to the kinds of external acts. (a) There is scandal in words, as profane language or calumnies spoken in a gathering of people. (b) There is scandal in acts, as when one is perceptibly drunk or fights in a city street. Scandal applies also to things, in so far as they are the result of acts or related to acts, such as disedifying books, pictures, dress. Thus, one gives scandal by having sinful objects on display, such as profane mottoes on one’s wall, obscene advertisements or announcements on one’s billboards. (c) There also may be scandal in omission, as when one is conspicuously absent from Mass on Sundays.

1449. The following kinds of sinful acts are not scandalous, for they are unknown to others, and hence cannot suggest sin: (a) internal acts, such as wicked thoughts, desires, emotions; (b) external acts concealed from others, such as inaudible profanity, intoxication not noticeable by others, omission of an obligatory penance about which others have no knowledge.

1450. There are, likewise, various divisions of scandal according to the internal purpose of the scandalizer. (a) Scandal is directly intentional, when the purpose of the scandalizer is to lead others to the guilt of sin (diabolical scandal). Example: Titus blasphemes religion before Caius in order that the latter may become irreligious, and thus be more easily persuaded to follow a life of crime. (b) Scandal is indirectly intentional when the purpose of the scandalizer is to perform some action whose nature is such that it will lead others to the guilt of sin, and he is determined to perform that action, although not directly willing the neighbor’s guilt that will result. Example: Titus does not like to see his children drunk, but he likes to get drunk himself occasionally, knowing all the while that his example encourages them to drink.

1451. In the following cases there is no intention of scandal: (a) when one does an act that has no appearance of evil, and one neither directly nor indirectly wills that it should be an occasion of sin to anyone. Example: Balbus performs his duties faithfully, although he knows to his regret that his fidelity occasions envy and hatred in Claudius; (b) when one does an act that is evil or apparently evil, but is invincibly ignorant of the scandal it may give. Example: Sempronius and Titus converse together in a foreign tongue which they confidently think Caius does not understand. The conversation is disedifying, and Caius, who does understand, is shocked by what they say.

1452. The act of the scandalizer who intends, directly or indirectly, the spiritual ruin of his neighbor, is called active scandal, while the act of the person who takes occasion from the active scandal to incur spiritual ruin, is called passive scandal. Active and passive scandal are sometimes together, sometimes apart. (a) Thus, there is both active and passive scandal, when the scandalizer wills the fall of his neighbor, and the scandalized does fall. (b) There is active but not passive scandal, when the scandalizer wills the fall of his neighbor, but the latter does not fall into the snare. (c) There is passive but not active scandal, when one makes the good action rightly performed by another an occasion of sin. Thus, some made the life and passion of our Lord a pretext for not accepting Him (Matt., xiii. 57; John, vi. 62; I Cor., i. 23), and are said to have been scandalized at Him.

1453. As to the act that occasions the spiritual ruin of another, it must be wrong either in reality or in appearance. (a) The scandalous act is wrong in reality, when it is forbidden as a sin—for example, offering sacrifice in the temple of an idol, or diverting to personal use money collected for the poor. (b) The scandalous act is wrong in appearance, when on account of circumstances it seems to be an act forbidden as a sin. Thus, to take part in a banquet held in a pagan temple might seem like participation in sacrificial rites (I Cor., viii. 10), to expend secretly the money collected for the poor might have the appearance of improper use of funds (II Cor., viii. 20, 21). Hence, St. Paul directs; “From all appearance of evil refrain yourselves” (I Thess., v. 22).

1454. The acts wrong in reality or in appearance that give scandal are innumerable, since the whole world is seated in wickedness (I John, v. 19). But today there are a number of acts that should be specially mentioned, as they occasion sin oftener or for more persons than other acts. Among these are: (a) occasions of sin against faith, such as atheistical literature, as discussed in the section on faith; (b) occasions of sin against morals, such as obscenity in dress, pictures, plays, writings, and dances. These last-mentioned will be discussed now in separate paragraphs.

1455. Obscenity.—Obscenity is a quality of words, acts or objects by which impure thoughts are conveyed, or impure desires or actions suggested. We may consider it either internally (i.e., in the intention of the person who uses the words, acts or objects) or externally (i.e., in the nature of the things themselves which are used).
