Moral Theology. Charles J. Callan
The general principles ("good is to be done," "evil is to be avoided") cannot vanish from the mind, although, in particular affairs, anger, pleasure, or some other passion may prevent men from thinking about them. Thus, when the mob spirit takes hold of a crowd, it becomes intent only on violence or revenge, and gives no thought to conscience. (b) The secondary precepts, such as those contained in the Decalogue, cannot be obliterated from the mind, although in applying them to concrete situations a people may go astray.
There are many examples of laws, both ancient and modern, which permitted or commanded, for particular cases, things contrary to the current application of natural precepts. Thus, the Spartans and the Romans ordered the murder of infants who were weakly and of slaves whose master had been killed. Some ancient races encouraged robberies committed beyond the boundaries of the states, and savage tribes have been found who had the practice of putting to death parents who were aged or infirm.
326. The causes of wrong applications of the Natural Law are the following:
(a) Some causes are involuntary. Thus, the correct application may be difficult, as when more than one moral principle has to be considered and applied; or, if the case is not difficult, the person who makes the application may be mentally undeveloped, or his mind may be blinded on account of his bad education or environment. Examples: The races who saw no infamy in robbery committed against their neighbors, lived in a wild age when such acts of violence seemed necessary as measures of self-protection. The savage killed his aged parents, because to his untutored mind this seemed an act of mercy.
(b) Some causes are voluntary, such as neglect of the truth, vicious habits, etc. Examples: St. Paul blames the pagans for their idolatry, because they had darkened their own minds about God. Pirates and bandits who came to regard violence as necessary for their own defense were responsible for their state of mind, inasmuch as they had chosen a life of crime.
327. Transgression of Natural Law, therefore, is not imputable as formal sin if it is not voluntary. Hence: (a) lack of knowledge excuses, when ignorance is involuntary (e.g., those who have not the use of reason, as infants and the unconscious; children and others mentally undeveloped who cannot grasp the meaning of some precept; educated persons who are unable to get a right solution of some knotty problem of morals, etc.); (b) lack of consent excuses in whole or in part (as when one acts through fear).
Art. 3: THE POSITIVE DIVINE LAW
(Summa Theologica, I-II, qq. 98–108.)
328. Meaning.—The Positive Divine Law is the law added by God to the Natural Law, in order to direct the actions of man to his supernatural End, to assist him to a better observance of the Natural Law, and to perfect that which is wanting in human law.
(a) The Last End of man is not natural, but supernatural (see 20), and hence it was necessary that, in addition to the precepts which guide man towards his natural beatitude, there should be added precepts that will guide him towards his supernatural beatitude: "The Law of the Lord gives wisdom to little ones" (Ps. xviii. 8).
(b) The light of natural reason was sufficient to instruct man in the Natural Law, but through sin that light had become obscured, with the result that evil customs set in, and very many were at a loss how to apply the Natural Law, or applied it wrongly. Hence, it was most suitable that the Natural Law should be summed up in brief commandments and given externally by the authority of God. This was done through the Decalogue, which is a part of the Positive Divine Law of both the Mosaic and the Christian dispensations: "The testimony of the Lord is faithful" (Ps. xviii. 8).
(c) Human laws are the product of fallible human judgment; they can direct only such acts as are external, and they are unable to forbid or punish many evil deeds. Hence, it was necessary that there should be positive divine laws to supply for what is wanting in human law: "The law of the Lord is unspotted, converting souls" (Ps. xviii. 8).
329. The Positive Divine Law differs from the Natural Law as to subject-matter, permanence, and manner of promulgation.
(a) The precepts of the Natural Law are necessary, since they follow as necessary consequences from the nature of man, the precepts of the Positive Law of God, excluding those that are external promulgations of the Natural Law, are not necessary, since they follow from the free decree of God raising man to that which is above his nature.
(b) The precepts of the Natural Law are unchangeable, since the nature of man always remains the same. Of the precepts of the Positive Law of God some were changed, because given only for a time (such as the ceremonial laws of Judaism); others, absolutely speaking, could be changed, because not necessarily connected with the end God has in view (e.g., the laws concerning Sacraments).
(c) The precepts of both kinds of law are immediately from God; but the Natural Law is promulgated only in a general way, through the light of reason given to man along with his nature, while the Positive Law of God is proclaimed by special commands (e.g., "thou shalt not steal").
330. The Positive Divine Law contains two kinds of precepts, viz., natural and supernatural commandments. (a) The natural precepts were given in order to recall to the minds of men the laws knowable through reason which had become obscured through passion, custom or example. The Commandments given to Moses on the tablets of stone renewed the natural precepts which God had written through reason on the hearts of men. (b) The supernatural precepts were given in order to point out to men the duties their supernatural destiny imposed. Example: The precepts of faith, hope, charity.
331. Division.—There are four historical states of man with reference to his Last End, and to each of these correspond positive divine laws.
(a) The state of Original Innocence is that which existed in Paradise before the Fall. Man had been raised to the supernatural state, and hence he was obliged to the supernatural acts of faith, hope, charity, etc.; he was subject to God, both as to body and soul, and hence he was obliged to offer some kind of external sacrifice; he was sanctified immediately by God, and hence was not bound to the use of any sacraments; but he was still in a state of probation, and was subject to various special regulations, such as the commands to avoid the fruit of a certain tree, to labor in Eden, etc.
(b) The state of the Law of Nature is that which existed from the Fall to the giving of the written law through Moses. It is called the state of the Law of Nature, not in the sense that there were no supernatural precepts then in force, but in the sense that there were as yet no written precepts. In that period man knew the Natural Law, not from commandments written on tablets of stone, but from the law of reason inscribed in his heart; he knew the supernatural precepts, not from scriptures given him by God, but from tradition or special divine inspiration. In addition to the inner acts of supernatural worship and faith in the Messiah to come and the outer sacrifices, there were during this state certain rites of purification, or sacraments, by which fallen man was purified from sin. A special precept of the patriarchial times was the prohibition made to Noe against the eating of flesh with blood in it.
(c) The state of the Mosaic Law is that which existed from the giving of the law on Sinai until the giving of the New Testament law by Christ.
(d) The state of the Christian Law, or of the New Law, is that which began with Christ and the Apostles and will continue till the end of the world.
332. The Mosaic Law.—This was the special law of God to the Jews, the people chosen by God as the race from which the Saviour of the world was to come. It has two periods: the period of preparation and the period of the Law.
(a)The period of preparation for the Law began with the Promise or Covenant given to Abraham. A law is not given except to a people (see 285), and, as the peoples of the world at that time had returned to the general corruption that reigned before the Deluge, God chose Abraham to be the father of a new nation in which true religion should be preserved until the Redeemer of the world had come. The rite of circumcision was ordered as a mark of the covenant and a sacrament of remission.
(b) The period of the Law began with the promulgation of the Decalogue on Sinai. The descendants of Abraham had grown into a nation and had been freed from slavery, and they were thus ready to receive a special law. Their history thereafter shows how God trained them according to the
