Of the New Law as Compared with the Old

Of the New Law as Compared with the Old — St. Thomas Aquinas asks: Whether the New Law is distinct from the Old Law?; Whether the New Law fulfils the Old?; Whether the New Law is contained in the Old?; Whether the New Law is more burdensome than the Old?.

We must now consider the New Law as compared with the Old: under which head there are four points of inquiry:

Article 1: Whether the New Law is distinct from the Old Law?

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 of the New Testament is distinct from that of the Old, as the Apostle shows in the same place. Therefore the Law is also distinct.

As stated above (; ), every law ordains human conduct to some end. Now things ordained to an end may be divided in two ways, considered from the point of view of the end. First, through being ordained to different ends: and this difference will be specific, especially if such ends are proximate. Secondly, by reason of being closely or remotely connected with the end. Thus it is clear that movements differ in species through being directed to different terms: while according as one part of a movement is nearer to the term than another part, the difference of perfect and imperfect movement is assessed.

Accordingly then two laws may be distinguished from one another in two ways. First, through being altogether diverse, from the fact that they are ordained to diverse ends: thus a state-law ordained to democratic government, would differ specifically from a law ordained to government by the aristocracy. Secondly, two laws may be distinguished from one another, through one of them being more closely connected with the end, and the other more remotely: thus in one and the same state there is one law enjoined on men of mature age, who can forthwith accomplish that which pertains to the common good; and another law regulating the education of children who need to be taught how they are to achieve manly deeds later on.

We must therefore say that, according to the first way, the New Law is not distinct from the Old Law: because they both have the same end, namely, man's subjection to God; and there is but one God of the New and of the Old Testament, according to Rom. 3:30: "It is one God that justifieth circumcision by faith, and uncircumcision through faith." According to the second way, the New Law is distinct from the Old Law: because the Old Law is like a pedagogue of children, as the Apostle says (Gal. 3:24), whereas the New Law is the law of perfection, since it is the law of charity, of which the Apostle says (Col. 3:14) that it is "the bond of perfection."

Article 2: Whether the New Law fulfils the Old?

Our Lord said (Mat. 5:17): "I am not come to destroy, but to fulfil": and went on to say (Mat. 5:18): "One jot or one tittle shall not pass of the Law till all be fulfilled."

As stated above (), the New Law is compared to the Old as the perfect to the imperfect. Now everything perfect fulfils that which is lacking in the imperfect. And accordingly the New Law fulfils the Old by supplying that which was lacking in the Old Law.

Now two things of every law is to make men righteous and virtuous, as was stated above (): and consequently the end of the Old Law was the justification of men. The Law, however, could not accomplish this: but foreshadowed it by certain ceremonial actions, and promised it in words. And in this respect, the New Law fulfils the Old by justifying men through the power of Christ's Passion. This is what the Apostle says (Rom. 8:3,4): "What the Law could not do . . . God sending His own Son in the likeness of sinful flesh . . . hath condemned sin in the flesh, that the justification of the Law might be fulfilled in us." And in this respect, the New Law gives what the Old Law promised, according to 2 Cor. 1:20: "Whatever are the promises of God, in Him," i.e. in Christ, "they are 'Yea'." [*The Douay version reads thus: "All the promises of God are in Him, 'It is'."] Again, in this respect, it also fulfils what the Old Law foreshadowed. Hence it is written (Col. 2:17) concerning the ceremonial precepts that they were "a shadow of things to come, but the body is of Christ"; in other words, the reality is found in Christ. Wherefore the New Law is called the law of reality; whereas the Old Law is called the law of shadow or of figure.

Now Christ fulfilled the precepts of the Old Law both in His works and in His doctrine. In His works, because He was willing to be circumcised and to fulfil the other legal observances, which were binding for the time being; according to Gal. 4:4: "Made under the Law." In His doctrine He fulfilled the precepts of the Law in three ways. First, by explaining the true sense of the Law. This is clear in the case of murder and adultery, the prohibition of which the Scribes and Pharisees thought to refer only to the exterior act: wherefore Our Lord fulfilled the Law by showing that the prohibition extended also to the interior acts of sins. Secondly, Our Lord fulfilled the precepts of the Law by prescribing the safest way of complying with the statutes of the Old Law. Thus the Old Law forbade perjury: and this is more safely avoided, by abstaining altogether from swearing, save in cases of urgency. Thirdly, Our Lord fulfilled the precepts of the Law, by adding some counsels of perfection: this is clearly seen in Mat. 19:21, where Our Lord said to the man who affirmed that he had kept all the precepts of the Old Law: "One thing is wanting to thee: If thou wilt be perfect, go, sell whatsoever thou hast," etc. [*St. Thomas combines Mat. 19:21 with Mk. 10:21].

Article 3: Whether the New Law is contained in the Old?

As expressed in Ezech. 1:16, there was "a wheel in the midst of a wheel," i.e. "the New Testament within the Old," according to Gregory's exposition.

One thing may be contained in another in two ways. First, actually; as a located thing is in a place. Secondly, virtually; as an effect in its cause, or as the complement in that which is incomplete; thus a genus contains its species, and a seed contains the whole tree, virtually. It is in this way that the New Law is contained in the Old: for it has been stated () that the New Law is compared to the Old as perfect to imperfect. Hence Chrysostom, expounding Mk. 4:28, "The earth of itself bringeth forth fruit, first the blade, then the ear, afterwards the full corn in the ear," expresses himself as follows: "He brought forth first the blade, i.e. the Law of Nature; then the ear, i.e. the Law of Moses; lastly, the full corn, i.e. the Law of the Gospel." Hence then the New Law is in the Old as the corn in the ear.

Article 4: Whether the New Law is more burdensome than the Old?

It is written (Mat. 11:28): "Come to Me, all you that labor and are burdened": which words are expounded by Hilary thus: "He calls to Himself all those that labor under the difficulty of observing the Law, and are burdened with the sins of this world." And further on He says of the yoke of the Gospel: "For My yoke is sweet and My burden light." Therefore the New Law is a lighter burden than the Old.

A twofold difficult may attach to works of virtue with which the precepts of the Law are concerned. One is on the part of the outward works, which of themselves are, in a way, difficult and burdensome. And in this respect the Old Law is a much heavier burden than the New: since the Old Law by its numerous ceremonies prescribed many more outward acts than the New Law, which, in the teaching of Christ and the apostles, added very few precepts to those of the natural law; although afterwards some were added, through being instituted by the holy Fathers. Even in these Augustine says that moderation should be observed, lest good conduct should become a burden to the faithful. For he says in reply to the queries of Januarius (Ep. lv) that, "whereas God in His mercy wished religion to be a free service rendered by the public solemnization of a small number of most manifest sacraments, certain persons make it a slave's burden; so much so that the state of the Jews who were subject to the sacraments of the Law, and not to the presumptuous devices of man, was more tolerable."

The other difficulty attaches to works of virtue as to interior acts: for instance, that a virtuous deed be done with promptitude and pleasure. It is this difficulty that virtue solves: because to act thus is difficult for a man without virtue: but through virtue it becomes easy for him. In this respect the precepts of the New Law are more burdensome than those of the Old; because the New Law prohibits certain interior movements of the soul, which were not expressly forbidden in the Old Law in all cases, although they were forbidden in some, without, however, any punishment being attached to the prohibition. Now this is very difficult to a man without virtue: thus even the Philosopher states (Ethic. v, 9) that it is easy to do what a righteous man does; but that to do it in the same way, viz. with pleasure and promptitude, is difficult to a man who is not righteous. Accordingly we read also (1 Jn. 5:3) that "His commandments are not heavy": which words Augustine expounds by saying that "they are not heavy to the man that loveth; whereas they are a burden to him that loveth not."
