Moral Theology. Charles J. Callan
(c) God can grant a dispensation in the wide sense from contingent precepts of the Natural Law—that is, He can make a change as regards the subject-matter, so that it no longer falls under the law. Thus, since God is the supreme Lord of life and property, He can without injury to human rights command that a person be put to death or deprived of his property by another. These acts would not constitute murder (i.e., unjust homicide) or stealing (i.e., unlawful taking); for God has a higher claim on life and possessions than the immediate owners have. Examples: The command to Abraham to kill his son was not a dispensation from the law against murder any more than the sending of death to the first-born of Egypt was the commission of murder by God. The command given the Israelites to carry away with them the goods of the Egyptians was not a dispensation from the law against theft, any more than the destruction of the fruits of the Egyptians by plagues was the commission of theft by God.
311. Is God able to make a decree which sets up a most grave public necessity opposed to the observance of a law of nature?
(a) If there is question of absolute laws (see 303), this cannot be done, for God cannot deny Himself by making a disposition contrary to His Eternal Law. Example: We do not read that God ever sanctioned polyandry or marriage between parent and child, and it seems that He could never permit such things as lawful.
(b) If there is question of relative laws (see 303), the decree in question can be made by God; for the unbecomingness of that which is forbidden by a relative law passes away in the face of a great need. Example: Since God desired the propagation of the human race from one man and one woman, marriage between brothers and sisters was not against the Natural Law at the beginning. Since God desired the speedy multiplication of the chosen people after the patriarchal era, polygamy was not repugnant to nature among the Jews of that period.
312. Is God able to remove a natural obligation in a case of private necessity, that is, when the fulfillment would be harmful to an individual?
(a) Natural obligations that do not depend upon any free consent of the will given to them (see 304) cannot be removed except by a dispensation widely so-called and when their matter is contingent (as explained in 309–310). Examples: God could not dispense an individual from the duty of confessing Him in order to escape death, for the subject-matter of the law here is necessary. God, could dispense an individual from the obligation of not taking the property of another, for God is the principal owner of all things, including those possessed by others.
(b) Natural obligations that depend upon the act or deed of human beings consenting to obligation (see 304) can be removed. For since human beings cannot know all the circumstances existent, or all the conditions that will arise, it can happen that a thing agreed to or promised is only seemingly good, or will change from good to bad, so that while the promise or agreement made is in itself good and naturally obligatory, its fulfillment would work harm and evil, or be useless, or would prevent the accomplishment of a greater good. It is reasonable, therefore, that God should release from obligation here, thus changing the subject-matter of the law, so that it is no longer comprehended under the law (see 309–310). Example: Titus vows or swears that he will give a certain alms or make a certain pilgrimage; but, when the time for fulfillment arrives, his circumstances have so changed that it would not be advisable for him to keep the promise made. The Church, acting in the name of God, can declare that the subject-matter of this promise has become harmful and is not longer suitable, and hence that the obligation has ceased.
313. Human Authority and Modification of the Natural Law.
(a) Additions to the Natural Law may be made, not only by positive laws of God, but also by human laws of Church or State, through the introduction of that which Natural Law permits, or the determination or confirmation of that which Natural Law contains implicitly or explicitly. Examples: Division of property rights introduced by the law of nations; conditions for valid contracts determined by particular codes; the laws against theft and murder confirmed by definite penalties prescribed for those crimes.
(b) Subtractions from Natural Law cannot be made by any human authority, for God has not delegated His power of dispensing which He has as supreme owner of all things. Examples: No human authority could authorize a father to sacrifice his innocent son, nor permit a servant to carry away the effects that belong to his employer.
314. Apparent Cases of Dispensation from Natural Law made by Human Authority. (a) The Church frees from the obligation of vows, contracts and promissory oaths, from impediments to marriage, from espousals, etc. In so doing, however, she does not dispense from the Natural Law that vows, contracts, etc., should be fulfilled, but only declares in the name of God that the subject-matter of an obligation contracted by act of man's will has become unsuitable for vow, contract, etc., and hence is no longer comprehended under the law.
(b) Societies or private individuals can free from the obligation of paying or returning to them what they have a right to, as when a creditor forgives a debt, or an owner permits a thief to keep what he stole. In so doing, however, they do not dispense from the law of nature that one should pay one's debts and not keep ill-gotten goods; they only change the quality of the things in question so that they cease to be due another or ill-gotten, and hence no longer fall under the law. This differs, too, from the dispensation that God can grant; for He can transfer rights without the consent of the immediate owner (see 310).
315. Interpretation—that is, explanation of the law which indicates whether or not it obliges in a particular case—may be applied to the Natural Law as follows:
(a) Interpretation which explains the intention the lawgiver had in making the law and the sense he gave to the words of the law (verbal interpretation), may be made when either a law itself is not entirely clear, or some person is not clever enough to see its meaning. Example: The commandment, "Thou shalt not kill," needs to be interpreted, for it does not forbid every kind of killing.
(b) Interpretation which explains the intention a lawgiver would have had, had he foreseen a particular case in which his law would be harmful, and which therefore sets the will of the lawgiver against the words of the law (emendatory interpretation, epieikeia), may not be applied to the Natural Law; for God, unlike human legislators, foresees things not only in general, but also in particular, and hence there is no room for correction or benign interpretation of natural laws. Example: Titus, who was a chronic invalid, committed suicide in order that his family might be freed from distress. He argued that the Fifth Commandment did not foresee the difficulties of earning a living under modern conditions, and that his sacrifice would be pleasing to God. Titus did not reason well, for suicide is forbidden for motives that apply universally (e.g., that society, and especially one's family, are injured by the act of suicide).
316. Verbal interpretation of the Natural Law is made as follows: (a) by private authority—that is, by those who are competent, on account of learning and prudence, to understand the meaning of the law, such as moral theologians; (b) by public authority—that is, by those who are appointed to rule, with the prerogative of declaring the meaning of the Natural Law. The Pope, since he must feed the flock of Christ, is divinely constituted to interpret Natural Law, and does so authentically and infallibly. Thus, the Church declares that certain matrimonial impediments are natural, and therefore incapable of being dispensed.
On the competence of the Church to give authoritative interpretations of the natural law in the field of morals, Pius XII has spoken clearly and forcefully: " … it must openly and firmly be held that the power of the Church has never been limited to the boundaries of strictly religious matters' as they are called; but the whole content of the natural law, its institution, interpretation and application are within its power insofar as its moral element is concerned. For the observation of the natural law, by the ordination of God, is the way by which man must strive to attain his supernatural end. On the road to this supernatural end. it is the Church that is his leader and guide. This is the way the Apostles acted, and from the earliest times the Church held to this way of acting as it does today—and not in the manner of a private leader and counselor, but from the command and authority of God" (AAS 46 [1954] 671–672).
317. From the foregoing it follows that the Natural Law is so unchangeable that it cannot be abrogated or properly dispensed, or given an emendatory
