unserviceable to the community. Examples are given in the previous paragraph.
(b) The law becomes harmful or useless with reference to the lawgiver's purpose privately or temporarily, if the harm or uselessness affects only individuals, or is not lasting. In this case the law continues to be an instrument of public welfare, or is only momentarily deprived of its beneficial character. Hence it endures; but for temporary inconvenience to the public a remedy is had in suspension of the law, for inconvenience to individuals in dispensation. Example: If the use of fats or grease were forbidden on days of abstinence, and if for a time only it were impossible to obtain the substitutes for the preparation of the food, the law would not cease, but would be suspended until such time as substitutes could be obtained.
503. The inconvenience caused to individuals from the fact that a law does not serve its purpose in a case before them, does not always justify the use of epieikeia.
(a) If the observance of the law would be detrimental to the purpose intended by the lawgiver, epieikeia might be used; for the lawgiver does not intend that his law should be an obstacle to what he has in view as its end. Example: Caius needs to read a book placed on the Index in order to defend the Faith against attacks, but he is unable to request the general faculty to read forbidden works. Obedience to the law in this case would defeat the purpose of the law, which is the protection of faith, and hence Caius may use epieikeia.
(b) If the observance of the law would be unnecessary, but not detrimental as regards the purpose of the lawgiver, epieikeia may not be used; else the law would lose its force through the judgments of individuals in their own favor, and the common welfare would suffer. Examples: Titus has an opportunity to read a book placed on the Index, but has not the time to apply for permission. The work was condemned as dangerous to faith; but Titus is strong in faith, and wishes only to study the literary qualities of the writer. Sempronius, a parish priest, is requested to officiate at a marriage immediately, without proclaiming the banns or seeking a dispensation from proclamation. The purpose of the law of banns is that impediments may be detected and invalid marriages avoided, and Sempronius is absolutely certain that there is no impediment in the case before him. Titus and Sempronius must observe the law, and the same must be said as regards every actual case in which there is the possibility of self-deception and peril to the common good. The theoretical case, in which neither of these inconveniences would be present, need not be considered.
504. The purpose of the law ceases to exist as follows:
(a) adequately, when all the reasons on account of which it was made are no longer in existence; in such a case the law itself ceases, for the lawgiver is not considered as intending to oblige when the reason for obligation has ceased. Example: If the bishop orders prayers to be said for rain, the prayers cease to be obligatory when rain has come;
(b) inadequately, when the reason for the law has ceased partially, but not entirely. In such a case the law does not cease, for it still remains useful. Example: If the bishop orders prayers for peace and rain, the prayers are obligatory until both requests have been obtained.
505. A law ceases, therefore, in greater or less degree, according to circumstances. (a) It ceases entirely or partially, according as it is revoked or as it becomes useless as to all its provisions, or only as to one or more of them; (b) it ceases permanently or temporarily, according as the revocation or cessation is only for a time, or for good.
506. Custom.—In Canon Law custom can interpret, abrogate or introduce law, provided: (a) it has the qualities of legitimate custom, and (b) its existence is proved juridically, or is notorious.
507. According to their extension, customs are of various kinds. (a) Universal customs are those that prevail in the entire Church; (b) particular customs are those that are confined to a territorial portion of the Church (e.g., a province of the Church or of an Order); (c) special customs are those that are followed in societies that are smaller, but capable of having their own laws (e.g., independent monasteries); (d) most special customs are those observed by individuals, or by communities not capable of having their own legislation (e.g., parishes). At the most, customs of this last class have only the force of privilege (Canon 26).
508. Custom is formed as follows. (a) As to origin, it arises from the practice of the people, when this practice is followed with the purpose of making or unmaking a law. Hence, the habitual way of acting of an individual, even if he be the superior, does not give rise to a custom. By "people" here is meant a community capable of having its own law (Canon 26). (b) As to legal force, custom arises solely from the consent of the Pope or other prelate, when this consent is expressed by the law or lawgiver, or tacitly admitted by him. Hence, a custom not approved by the superior has no legal force (Canon 25).
509. A custom can introduce or abrogate any kind of ecclesiastical law or other custom—penal, prohibitive, irritant—if it is reasonable and has lasted the prescribed time (Canons 27, 28). Examples: A law that forbids contrary customs can be abrogated, according to the Code, by such customs when they are immemorial, or a century old (Canon 27, § 1). The impediment of disparity of worship became diriment through custom; it was custom that introduced the obligation of the Divine Office, and that mitigated the early law of fast.
510. A custom expressly disapproved of in law is not reasonable or legitimate, and cannot derogate from an existing law, nor establish a new law (Canons 27, 28).
511. The time prescribed by the Code of Canon Law for the acquisition of legal force by customs that have not the personal consent of the lawgiver is as follows: (a) forty continuous and complete years are required to unmake an ordinary law; one hundred years to unmake a law that forbids future contrary custom (Canon 27, § 1); (b) forty continuous and complete years are likewise required to make a new law (Canon 28).
512. The effect of the Code on customs previously existing was considered above under 421.
513. Like the written law, custom ceases: (a) from within, when its purpose has ceased entirely; (b) from without, when it is abrogated by desuetude, or by a contrary law or custom (Canon 30).
514. Laws in a Wide Sense.—In addition to laws strictly so-called, there are laws in a wide sense, commands or provisions made by ecclesiastical superiors that have not all the conditions given above (see 285) for law. Such are: (a) precepts, which differ from law, because they are given not to the community or permanently, but to individuals or temporarily; (b) rescripts, which are given with regard to particular cases and without the solemnity of law; (c) privileges, which are not obligatory; (d) dispensations, which are relaxations of law granted to individuals.
515. A precept is a command given to individuals, or for an individual case, by a competent superior.
(a) It is a command obliging in conscience, and so differs from counsel, desire, exhortation.
(b) It is given to individuals, and thus differs from law, which has the character of universality and stability. A precept may be imposed on a community, but even then it is particular, as being given only for an individual case or for a certain length of time—for a month or a year, or during the lifetime of the superior.
(c) It is given by a competent superior. Even here precept differs from law, since laws can be made only by one who has jurisdictional or public authority (see above, 285), while precepts may be given also by those who have only dominative or private authority (as parents, heads of families, husbands, employers, abbesses). In canonical matters precepts may be given by religious superiors, parish priests, rectors of seminaries, and for the court of conscience by the confessor.
516. Precept is similar to law: (a) as to its object, which must be just, good, and possible of observance; (b) as to its binding force, since it can be imposed even on those who are unwilling.
517. Precepts are personal (i.e., they affect the person to whom they are given wherever he may be), unless they are given as territorial (Canon 24). Hence: (a) a precept given by one who has no territorial authority (e.g., a religious superior) is personal; (b) a precept given by the Pope, whose authority includes every territory, is also personal; (c) a precept given by the bishop is personal, if given to an individual; it is personal or territorial if given to a community, according to the nature of the case or the wording
