Moral theology

370. Definition.—Since human perversity often needs a check in regulations that are not expressly contained in the Natural or in the Divine Law, other laws must be made by society, drawn from those higher laws as conclusions or added to them as determinations, in order to meet special circumstances and necessities.

b) According to their mode of derivation from the Natural Law, laws belong either to the law of nations (_jus gentium_) or to civil law. To the _jus gentium_ belong those laws which are derived from the Natural Law as conclusions from premises, e.g., the right to private property without which men cannot live peacefully in society. To civil law belongs whatever is derived from Natural Law by way of positive determination by a legislator; e.g., Natural Law dictates that the evil-doer be punished; but that the punishment take a particular form, imprisonment, exile, death, is a determination depending upon the will of the legislator.

The _jus gentium_ is not international law which derives its force and sanction from the free will of the legislator. The law of nations is common to all men and derives its force from the conviction of men that such a law is demanded for the good of mankind. It is not a secondary precept of the Natural Law which is derived from the primary precepts necessarily. Rather it is based upon a contingent set of circumstances; it does not spring from man’s nature absolutely considered, but from the way in which man acts and reacts in his society.

(c) According to the difference of their objects, laws are either affirmative (i.e., preceptive) or negative (i.e., prohibitive). An affirmative law obliges always, but not for every occasion; a negative law obliges always, and for every occasion. Example: The Third and Fourth Commandments are always in force, but it is not necessary to elicit a positive act of compliance at every instant. The other Commandments, which are negative, are not only in force always, but it is necessary at every instant to omit what they forbid.

(e) According to their inclusiveness, laws are either personal or territorial. The former affect the person for whom the law is made, and oblige him even when he is outside the territory of the lawgiver. The latter affect the territory, and hence do not oblige a subject when he is outside the territory affected by the law.

373. Laws fail to be of public benefit in such cases as the following: (a) if they are made without a broad view of the public good, which has regard for different classes of people and various interests, and which provides for the future as well as for the present; (b) if, losing sight of the fact that the majority are not perfect in virtue, the lawgivers require so much that the law falls into contempt, and graver evils result than would have happened otherwise. Hence, it is advisable that human laws confine their prohibitions to graver misdeeds, especially those that are harmful to others and to society, and restrict their commands to such good acts as promote the common weal. Multiplicity of laws, excessive penalties for minor offenses, cruel and unusual sanctions, lead to lawlessness.

(a) They should not prescribe heroic virtue, unless the common safety demands it, or a subject has voluntarily obliged himself to it. Example: Soldiers in war and pastors in time of pestilence must expose themselves to danger of death; but for ordinary occasions the law should not oblige one to risk one’s life or other great good.

(b) They should not prescribe agreement with the mind of the legislator or a virtuous performance of what is prescribed, unless the thing ordered itself demands this. Examples: The law of annual Confession and of the Easter Communion requires, not only that these Sacraments be received, but that they be received worthily, for an unworthy Confession is no Sacrament, and an unworthy Communion does not satisfy the command of Christ, of which the Church command is but a determination. On the other hand, the Lenten fast observed by one who is not in the state of grace is an act good in itself and satisfies the law. He who hears Mass on a holyday, not knowing that it is a holyday, satisfies the obligation, though he had no intention of fulfilling it.

375. Obligation of Human Laws.—All human laws that are just, whether they be ecclesiastical or civil, made by believers in God or unbelievers, are obligatory in conscience, (a) From the beginning the Church has made laws and imposed them as obligatory (Acts, xv. 29; I Cor., vi. 4; I Cor., xi. 5; I Tim., v. 9-12), and has recognized as obligatory the laws of the State, without regard to the moral or religious qualifications of the rulers (I Peter, ii. 13-16; Rom., xiii. 1-7).

(b) Human laws are necessary. The Natural Law does not prescribe definite penalties, while the Positive Divine Law prescribes only such as are remote and invisible; and hence, if there were no human laws holding out the threat of determined and present punishments, the Divine laws would be contemned. Moreover, since the higher laws are sometimes unknown, or prescribe no time, place or manner of accomplishment, or do not command things that would be useful for their observance, it is necessary that there be laws made by man to secure the better knowledge and fulfillment of the laws given by God Himself.

(a) if opposed to the rights of God. Examples: The command of Pharaoh that the Hebrew male children be murdered (Exod., i. 17), the command of Antiochus that his subjects sacrifice to idols (I Mach., ii. 16-20), the command of the Sanhedrin that the Apostles should cease to preach (Acts, v. 29);

(b) if opposed to the rights of man. This happens in three ways: First, when the purpose of the law is not the common good, as when the lawgiver seeks only his own profit or glory; secondly, when the maker of the law has not the requisite authority; thirdly, when the law itself, although for the common good and made by competent authority, does not distribute burdens equally or reasonably among the people. Examples: Achab and Jezabel, in the affair of the vineyard of Naboth, had in view not the public, but their own private benefit (III Kings, xvi). The sentence of death pronounced on our Lord by the Sanhedrin was illegal, because, among other reasons, the body was not assembled according to law, and hence had no authority to give sentence. The commands given the Israelites by Pharaoh (Exod., v. 18), and to their subjects by Oriental despots (I Kings, viii), were unjust, because the former discriminated against the Israelites, and the latter bore down too heavily on all the people. The former civil laws that prescribed the same penalty of hanging for a slight misdemeanor (such as the theft of a loaf of bread by a boy) as for the capital crimes of piracy or murder, the Stamp Act of George III, and some modern laws that sentence to life imprisonment those who have been four times convicted of slight offenses, are more recent examples of unjust laws.

377. Obedience to unjust laws is not obligatory in the following cases. (a) If a law is opposed to the rights of God, it is not lawful to do what that law commands or permits, nor to omit what it forbids. Examples: If a law permits one to practise polygamy, or commands one to blaspheme religion, one may not use the permission or obey. If a law forbids one to give or receive Baptism, it has no force. (b) If a law is certainly opposed to the rights of man in any of the three ways mentioned in the previous paragraph (376, b), it does not of itself oblige in conscience, since it lacks some essential condition of a true law, and even the consent of the majority or of all does not make it just. However, it may oblige accidentally, on account of the greater evils that would follow on disobedience, such as scandal, civil disturbances, etc. The duty of subjects is to remonstrate against such a law and to work for its repeal.

378. The obligation of all laws is not the same in kind, or degree. (a) Moral laws oblige one to do what is commanded or to omit what is forbidden, as a duty owed in conscience; hence, he who violates a law of this kind is guilty of moral fault. Penal laws oblige one to follow what they prescribe, if one would be free from guilt before the law and not liable in conscience to the penalty prescribed; hence, he who violates a penal law is guilty of juridical fault, and, if he further illegally resists the penalty, he becomes guilty also of moral fault. (b) Moral laws are not all of the same obligatory force, some of them obliging under grave sin, others under venial sin.

379. The following human laws are recognized as moral laws: (a) ecclesiastical laws, with few exceptions; (b) civil laws that confirm the Eternal or Divine Law, or that pertain directly to the common welfare, such as the laws that determine the duties of public officials, the rights of inheritance, etc.

380. The following human laws are generally regarded as merely penal: (a) ecclesiastical laws which expressly state that their observance is not required under pain of sin (e.g., the statutes of many Religious Orders); (b) civil laws of minor importance, or which the legislator imposes as a purely civil duty (e.g., some traffic regulations).

381. Moral laws oblige under grave sin if the two following conditions are present: (a) if the thing prescribed by the law is of great importance, because of its nature or circumstances; (b) if the lawgiver intended to impose a grave obligation.

382. A matter of light moment cannot be made the object of a law that binds under grave sin, for this would impose an intolerable burden, and would thus be contrary to the common good. What is unimportant in itself, however, may become important on account of its purpose or other circumstance.

383. The intention of the legislator to impose a grave moral obligation is recognized either: (a) from his own declaration, as when a church law is commanded under threat of the divine judgment; or (b) from circumstances that indicate such an intention, such as the gravity of the subject-matter of the law or the kind of penalty it prescribes, the general opinion of authorities, or the common practice of the community.

384. By obliging to the observance of what they command and the avoidance of what they forbid, laws indirectly oblige to what is necessary for such obedience. (a) Hence, the law obliges one to make use of the ordinary means for its fulfillment. Examples: He who has not used ordinary diligence to know the law, sins against the law if he violates its prescriptions. He who eats meat on a day of abstinence, because he neglected to provide himself with other food, is guilty of sin. (b) The law obliges one to use sufficient diligence in removing impediments to its fulfillment or dangers of its violation. Examples: The law of hearing Mass on Sunday obliges one not to stay up so late on Saturday that fulfillment will be impossible. The law of fasting obliges one to avoid dangerous occasions of its violation.

385. Interpretation.—Though laws are carefully framed as to language, doubts about their meaning will often arise—in ordinary cases, because of lack of understanding or changes of conditions, and in extraordinary cases, because from the circumstances the law seems inapplicable. Hence the need of explaining the law, which is done in ordinary cases by interpretation, in extraordinary cases by _epieikeia_ (see 411 sqq.).

(a) According to the author from whom it proceeds, interpretation is authentic, if it comes from the lawgiver himself or from another authorized by him; it is usual, if it comes from common usage (i.e., from the manner in which the law is customarily observed); it is doctrinal, if it is made by learned men according to the rules of correct exegesis.

(c) According to the manner in which it is made, interpretation is strict or wide, Strict interpretation gives to a word of law that least inclusive and most proper signification it bears (e.g., it understands “son” to stand for son by birth). Wide interpretation gives to a word a more inclusive and less proper signification (e.g., it understands “son” to stand for son by birth or by adoption).

387. Those Subject to Law.—Only those are morally obliged to observe human law who are subjects of the lawgiver and who have the use of reason. (a) Those who are not subjects in any sense are not bound, for to obligate by law is an act of authority and jurisdiction; (b) those who have not reached the age of reason, or who are habitually insane, are not themselves morally bound, since they are incapable of moral obligation. Of course, they may be restrained as to acts, and their rights may be determined.

388. The lawgiver himself, even though not subject, is held to observe the laws he makes. Thus: (a) if the lawmaking power resides in a legislative assembly, each legislator is subject to the body and hence to its laws; (b) if the lawmaking power is vested in an individual, he is not subject to the coactive force of his own laws, since he cannot punish himself; but he is subject to their directive force, inasmuch as the higher law of nature requires that the superior show good example by observing what he requires of others.

389. Change of Law.—The growth of knowledge and experience, or the change of social circumstances, requires now and then that human laws be improved or adapted to new conditions. But, since laws derive a great part of their influence from custom, they should not be changed unless the break with custom is compensated for by the urgent necessity of the new law, by its manifest advantage, or by the evident iniquity or harmfulness of the old law, In brief, the common good should be the norm by which to decide whether a law should be retained or changed.

390. Constitutional law, as being fundamental and organic, is more immutable than ordinary law. (a) If given to a society established according to the positive ordinance of a superior, it cannot be abrogated or modified by the legislative authority of that society, since this would be contrary to the will of the founder. Hence, the Church has no power to change the fundamental constitution given her by Christ, who prescribed the religious society as established by Him to be necessary. (b) If a constitutional law is given to a society which is perfect and necessary from the law of nature, such constitution can be modified for extraordinary reasons and in the special ways provided (e.g., by amendments approved by the people).

391. The Law of Custom.—Custom (i.e., a long-continued practice that has acquired binding force) is able to establish a new law or to do away with an old law. For the will of the lawgiver is manifested not only by words, as happens in the written law, but also and more clearly by repeated and continued acts, as happens in the case of the unwritten law of custom. In a democracy it is the consent of the people who follow the custom as law that imposes the obligation; in a monarchy it is the consent of the ruler who permits the custom.

392. With reference to their legal effects, there are three kinds of customs: (a) customs according to the law, which are those that confirm by use an existing law; in this way custom interprets law (see 386); (b) customs beside the law, which are those that introduce a new obligation that is not prescribed by any written law; in this way custom establishes law; (c) customs contrary to law, which are those that remove the obligation of a previous law; in this way custom repeals, at least in part, the law to which it is opposed.
