FOURTH ARTICLE [I-II, Q. 91, Art. 4]

Whether There Was Any Need for a Divine Law?

Objection 1: It would seem that there was no need for a Divine law.

Because, as stated above (A. 2), the natural law is a partic.i.p.ation in us of the eternal law. But the eternal law is a Divine law, as stated above (A. 1). Therefore there was no need for a Divine law in addition to the natural law, and human laws derived therefrom.

Obj. 2: Further, it is written (Ecclus. 15:14) that ”G.o.d left man in the hand of his own counsel.” Now counsel is an act of reason, as stated above (Q. 14, A. 1). Therefore man was left to the direction of his reason. But a dictate of human reason is a human law as stated above (A. 3). Therefore there is no need for man to be governed also by a Divine law.

Obj. 3: Further, human nature is more self-sufficing than irrational creatures. But irrational creatures have no Divine law besides the natural inclination impressed on them. Much less, therefore, should the rational creature have a Divine law in addition to the natural law.

_On the contrary,_ David prayed G.o.d to set His law before him, saying (Ps. 118:33): ”Set before me for a law the way of Thy justifications, O Lord.”

_I answer that,_ Besides the natural and the human law it was necessary for the directing of human conduct to have a Divine law.

And this for four reasons. First, because it is by law that man is directed how to perform his proper acts in view of his last end. And indeed if man were ordained to no other end than that which is proportionate to his natural faculty, there would be no need for man to have any further direction of the part of his reason, besides the natural law and human law which is derived from it. But since man is ordained to an end of eternal happiness which is improportionate to man's natural faculty, as stated above (Q. 5, A. 5), therefore it was necessary that, besides the natural and the human law, man should be directed to his end by a law given by G.o.d.

Secondly, because, on account of the uncertainty of human judgment, especially on contingent and particular matters, different people form different judgments on human acts; whence also different and contrary laws result. In order, therefore, that man may know without any doubt what he ought to do and what he ought to avoid, it was necessary for man to be directed in his proper acts by a law given by G.o.d, for it is certain that such a law cannot err.

Thirdly, because man can make laws in those matters of which he is competent to judge. But man is not competent to judge of interior movements, that are hidden, but only of exterior acts which appear: and yet for the perfection of virtue it is necessary for man to conduct himself aright in both kinds of acts. Consequently human law could not sufficiently curb and direct interior acts; and it was necessary for this purpose that a Divine law should supervene.

Fourthly, because, as Augustine says (De Lib. Arb. i, 5, 6), human law cannot punish or forbid all evil deeds: since while aiming at doing away with all evils, it would do away with many good things, and would hinder the advance of the common good, which is necessary for human intercourse. In order, therefore, that no evil might remain unforbidden and unpunished, it was necessary for the Divine law to supervene, whereby all sins are forbidden.

And these four causes are touched upon in Ps. 118:8, where it is said: ”The law of the Lord is unspotted,” i.e. allowing no foulness of sin; ”converting souls,” because it directs not only exterior, but also interior acts; ”the testimony of the Lord is faithful,” because of the certainty of what is true and right; ”giving wisdom to little ones,” by directing man to an end supernatural and Divine.

Reply Obj. 1: By the natural law the eternal law is partic.i.p.ated proportionately to the capacity of human nature. But to his supernatural end man needs to be directed in a yet higher way. Hence the additional law given by G.o.d, whereby man shares more perfectly in the eternal law.

Reply Obj. 2: Counsel is a kind of inquiry: hence it must proceed from some principles. Nor is it enough for it to proceed from principles imparted by nature, which are the precepts of the natural law, for the reasons given above: but there is need for certain additional principles, namely, the precepts of the Divine law.

Reply Obj. 3: Irrational creatures are not ordained to an end higher than that which is proportionate to their natural powers: consequently the comparison fails.

FIFTH ARTICLE [I-II, Q. 91, Art. 5]

Whether There Is but One Divine Law?

Objection 1: It would seem that there is but one Divine law. Because, where there is one king in one kingdom there is but one law. Now the whole of mankind is compared to G.o.d as to one king, according to Ps.

46:8: ”G.o.d is the King of all the earth.” Therefore there is but one Divine law.

Obj. 2: Further, every law is directed to the end which the lawgiver intends for those for whom he makes the law. But G.o.d intends one and the same thing for all men; since according to 1 Tim. 2:4: ”He will have all men to be saved, and to come to the knowledge of the truth.” Therefore there is but one Divine law.

Obj. 3: Further, the Divine law seems to be more akin to the eternal law, which is one, than the natural law, according as the revelation of grace is of a higher order than natural knowledge.

Therefore much more is the Divine law but one.

_On the contrary,_ The Apostle says (Heb. 7:12): ”The priesthood being translated, it is necessary that a translation also be made of the law.” But the priesthood is twofold, as stated in the same pa.s.sage, viz. the levitical priesthood, and the priesthood of Christ. Therefore the Divine law is twofold, namely the Old Law and the New Law.

_I answer that,_ As stated in the First Part (Q. 30, A. 3), distinction is the cause of number. Now things may be distinguished in two ways. First, as those things that are altogether specifically different, e.g. a horse and an ox. Secondly, as perfect and imperfect in the same species, e.g. a boy and a man: and in this way the Divine law is divided into Old and New. Hence the Apostle (Gal. 3:24, 25) compares the state of man under the Old Law to that of a child ”under a pedagogue”; but the state under the New Law, to that of a full grown man, who is ”no longer under a pedagogue.”

Now the perfection and imperfection of these two laws is to be taken in connection with the three conditions pertaining to law, as stated above. For, in the first place, it belongs to law to be directed to the common good as to its end, as stated above (Q. 90, A. 2). This good may be twofold. It may be a sensible and earthly good; and to this, man was directly ordained by the Old Law: wherefore, at the very outset of the law, the people were invited to the earthly kingdom of the Chananaeans (Ex. 3:8, 17). Again it may be an intelligible and heavenly good: and to this, man is ordained by the New Law. Wherefore, at the very beginning of His preaching, Christ invited men to the kingdom of heaven, saying (Matt. 4:17): ”Do penance, for the kingdom of heaven is at hand.” Hence Augustine says (Contra Faust. iv) that ”promises of temporal goods are contained in the Old Testament, for which reason it is called old; but the promise of eternal life belongs to the New Testament.”

Secondly, it belongs to the law to direct human acts according to the order of righteousness (A. 4): wherein also the New Law surpa.s.ses the Old Law, since it directs our internal acts, according to Matt. 5:20: ”Unless your justice abound more than that of the Scribes and Pharisees, you shall not enter into the kingdom of heaven.” Hence the saying that ”the Old Law restrains the hand, but the New Law controls the mind” ( Sentent. iii, D, xl).
