Why then the law? It was added because of transgressions, till the descendant should come to whom the promise was made; and it was ordained by angels in the hand of a mediator.

Wherefore then serveth the law? Why was the law introduced after the promise? Is it that God does not fulfil His promise? The answer is that the law was given by God to restrain and punish transgressions. This was its direct purpose, but indirectly it served as a means whereby transgressions might be made manifest. A self-willed people would, on hearing the law, recognise their sins as such, and feel the need of Christ"s grace if they were to keep it. In this way the law sent men to Christ.
Till the seed should come. Till the birth of Christ, to whom God had promised that by Him all nations should be blessed, i.e, justified, and so be able to live uprightly and to keep the law. The law was given as a pedagogue till Christ should come; therefore when Christ has come it has done its work, and the Jews are foolish in wishing to prolong its power.
Because of transgressions. The Greek word rendered added denotes put in its place, as a soldier is assigned his post by his general. So the law was assigned its rank, place, time, and method of promulgation.
1. It was given its rank between the law of nature and the Gospel, being more perfect than the one but inferior to the other. It was a road from one to the other.
2. It was given its fitting time, in being promulgated to a people still uncouth, when it was about to form itself into a nation and a Church, to prevent it from failing into idolatry and heathen license.
3. It had its due place, for being given at Sinai before the entrance into Canaan, it formed a sort of condition to the covenant. God promised that He would lead the Hebrews into Canaan, and put them in possession of it, if they would follow the law as their guide, and observe it as a condition attached to His promise.
4. It had its proper mode of promulgation, for it came from an angel on Mount Sinai, with the sound of a trumpet, with a terrible earthquake, with thunder and lightning, as a law of fear to restrain the rebellious Jews, like slaves, by fear of punishment. In these four ways the law was externally ordered.
5. But it was also internally disposed in due order. Its precepts bade the Hebrews (a) worship God by appointed ceremonies and sacrifices; (b) refrain from injury to their neighbour, or if injury had been inflicted, it bade them offer fitting satisfaction; (c) it regulated the inner man by the moral precepts of the Decalogue.
Similarly, but much more perfectly, has the New Law, the law of Christ, been ordered. (1.) It was assigned its proper rank, as being the crown and perfection of all laws. (2.) It came in its proper time, viz, in the last age of the world, when Christ, the great Legislator, came. It was promulgated at Pentecost, on the fiftieth day after the Passover, which was a feast symbolical of pardon, freedom, bliss, and the eternal jubilee. (3.) Its place was befitting its dignity. Not on Sinai was it given but on Sion, the type and mirror of celestial glory, to which this law leads us. (4.) As to the mode of promulgation, notice that it was given with a mighty wind and fiery tongues, with the power and might of the Holy Spirit, to preach the Gospel and convert all nations, because it was a law of burning love and enkindled charity. (5.) Its contents were duly related to one another, through its precepts of faith, hope, charity, and those relating to justification and the Sacraments.
It was ordained by angels. From this it appears that it was not God who in person spoke to Moses, but an angel representing Him, and speaking in His Name; as when he said, "I am the Lord thy God." Even so an ambassador speaks in the name of his sovereign, and acts by his authority. It was then an Angel who, in the place of God, was the immediate giver of the Decalogue to the people on Mount Sinai. It was an Angel also who spoke with Moses on Mount Sinai, and gave him for promulgation to the people the ceremonial laws, with directions for the making of the Tabernacle, for the ark, the cherubim, the sacrifices, and expiatory rites, which are found scattered throughout the Pentateuch.
In the hand of a mediator. Hand is here used to denote instrumentality. By a similar usage the word of the Lord is said to have come to pass in the hand of Elijah, Isaiah , and other prophets, acting as the instruments of God. Vatablus has for mediator intercessor, and Erasmus conciliator. But mediator, as the more intensive term, is preferable. Whoever mediates between two may be either a messenger, or an interpreter, or a peacemaker, and in each sense he is a mediator.
What mediator is referred to here? 1. Jerome, Augustine, Chrysostom, and Ambrose reply, Christ the Lord. Although Christ was not then actually our mediator, yet He was by the decree and in the purpose of God. The Old Law, in this sense, was given by the power and authority of Christ, who was the predestined Mediator; and since, therefore, the law was given by His authority, so when He was born into the world it was in His power to abrogate it.
2. The answer of Cyril (Thesauri, xii10), Gregory Nazianzen (Orat6 before Greg. Nyss.), Catharinus, Adam, and others, including even Beza, is better, viz, that the mediator was Moses, who himself says, in Deuteronomy v5 , that he stood between the Lord and the people at that time. This opinion is supported by the consideration (a) that Christ cannot be said to be a mediator as God, but only as God-made-man. But at the time of Moses He was not yet made Prayer of Manasseh , and therefore could not then be called a mediator. The major of this syllogism is proved thus: Christ as God only, just as Christ as man only, is but one of two extremes; therefore as such He cannot be a mediator, but only as God-man. As the God-man He unites in His person the two extremes of God and man. As God He had the authority and dignity belonging to a mediator; as man He did the work of a mediator. It may be objected to this, no doubt, that though Christ was not then actually a mediator, yet He was by predestination. But this objection loses sight of the fact that the Apostle is not speaking of a mediator by predestination, but of an acting mediator; for he says that the Old Law was ordained by this mediator, i.e, in very deed, when it was given to the Hebrews. But Christ, not yet existing as mediator, could not have ordained the law at that time; therefore He was not its mediator, for what has no existence can neither work nor ordain anything.
(b) The phrase of S. Paul means that angels gave the law by the instrumentality of a mediator. But Christ cannot be said to be the minister of angels but their Prince (cf. Hebrews 1.); therefore, the mediator here is not Christ. (c) Again, the Old Law was given by Moses, as the New Law by Christ. As, then, Christ is the mediator of the New Law and the New Covenant, so was Moses of the old. (d) Lastly, that Moses was the mediator is clear from Hebrews 8:5-6, and Hebrews 9:15-20.
Observe, in opposition to the Protestants, that if Moses could be called a mediator without any derogation from the mediatorial office of Christ, as even Beza admits, in the sense, not of a redeemer or reconciliator, but as a messenger from one to the other, why may not the Saints with even better title be called mediators without offence to Christ, seeing that by their merits and prayers they gain for us the grace of God? It is astonishing that Protestants should make so much fuss about this word, and strive to throw so much dust in people"s eyes, when, as is evident, there is no difference between us, either about the name or the thing.
The meaning of the Apostle, then, is this: The Old Law was given by angels and promulgated by Moses, the New by Christ Himself. He who as God used the instrumentality of Moses in proclaiming the Old Law, could, when made Prayer of Manasseh , abrogate it in His own person, in order that "the promise made to Abraham, that all nations should be justified, might be fulfilled in Himself, the seed of Abraham.
