For this reason, when the Lord came and all such people cleaved to Him, the remaining part of Israel was scattered over the face of the earth. Though outwardly it was more visible, it was scattered for its own rebuke and for the confirmation of God’s truth.
Saint Chrysostom says on the words “because of transgressions”: “Therefore the law is not superfluous. Do you see how he harmonizes everything, and with how many eyes he looks at all things? Since he exalted faith and showed that it is older than the law, lest anyone think the law superfluous, he resolves this difficulty also. He says that the law was given not in vain, but with very great benefit, because of transgressions. That is, so that the Jews might not live without fear and reach the height of impiety. For this reason the law was given to them as a bridle, for their instruction, taming, and restraint. It kept them from transgressing, if not all the commandments, at least some. Therefore there is no small benefit from the law.”
“It was added.” To whom, and to what? One may have neither object in mind and understand “was added” in the sense that the law is something supplementary. It has no independent significance and does not stand by itself.
Oecumenius writes: “He said well, ‘was added,’ to show that the law is not the original institution, but was given as something supplementary. It was not given for endless time, but until Christ should come, in Whom blessing was promised to all nations.”
Or else, it was added to the promise, to serve as a means toward its realization. The purpose of the law and of the people organized under it was that, in due time, the promise given to Abraham might be fulfilled.
Or else, it was added to the people, in the sense that it was laid upon the people, or that the people were enclosed by it. For the Jew was indeed enclosed by the law in every manifestation of life, at home, in the temple, at work, and on the road.
If the law was a healing plaster for morals, no more suitable treatment could have been devised. Yet the first meaning is the most direct.
“Until the Seed should come, to whom the promise was made,” that is, the Seed of Whom it is said in the promise that in Him all nations shall be blessed. He indicates this limit intentionally, to suggest that, if he insists on the abolition of the law, he does nothing unjust.
Such is the lot of the law according to its original purpose. Since the Seed of promise has come, it is evident that the law has fulfilled its work and now must cease. “If the law was given only until the coming of Christ, why do you prolong it further, beyond the limits of that time?” (Saint Chrysostom).
“Ordained through angels.” The angels are not the makers of the law, but ministers at its institution. They stood on God’s behalf, and Moses on the people’s behalf. God inspired them, they transmitted it to Moses, and Moses to the people.
By appearing on Sinai, God showed that the law came from Him. Yet the law had many details. It was more fitting for these to be transmitted and interpreted through angels.
It is said to Moses: “See that you make them according to the pattern shown you on the mountain” (Ex 25:40). Since the Old Testament service was wholly typological, Moses had to see it in images. He saw the images of everything on the mountain, and the angels interpreted them, explaining what each thing meant and why it was needed.
Yet everything was from God. Moses himself testified before his death: “The Lord came from Sinai,” and “He came with myriads of holy ones; at His right hand were angels with Him” (cf. Deut 33:2).
All the Jews believed that “God spoke to Moses” (Jn 9:29). At the same time they held that the law was received by the arrangement of angels (Acts 7:53), as the protomartyr Stephen said before all and to all.
Therefore, in another place, when writing to the Hebrews, Saint Paul did not think he was saying anything repellent or contrary to their faith. He said that the whole law is “the word spoken through angels” (cf. Heb 2:2).
Why did the Apostle mention this, when for his purposes he could have done without it? He was led to it by the mediating significance of the law just expressed. The promise, he says, had original and independent significance, but the law was added, and that only for a time, “until.”
Since it has such a lower significance before the promise, it was also lower than the promise in its arrangement. The promise was given face to face by God to Abraham. The law was ordained through angels, and also by the hand of a mediator.
Two stages separated the people from God: Moses below and the angels above. But the promise was given personally by God Himself.
From this one could also infer the superiority of the New Covenant over the law, since it is the fulfiller of the promise. The Apostle does not unfold this here. He did so in the Epistle to the Hebrews.
“By the hand of a mediator” means through a mediator. This is a Hebrew turn of speech, since the hand is the most convenient organ of the widest activity. But who is the mediator here?
Most directly, it is Saint Moses. The discussion concerns the law, and at its institution Moses was the mediator from Israel’s side, by God’s election. He spoke to the people on God’s behalf, and the people themselves chose him for this (cf. Ex 20:19).
Moses later confesses this in his farewell speeches to the people: “I stood between the Lord and you at that time, to declare to you the words of the Lord” (cf. Deut 5:5).
For this reason Saint John the Evangelist sets the work of Moses alongside the work of the Lord Jesus Christ, saying: “The law was given through Moses, but grace and truth came through Jesus Christ” (cf. Jn 1:17).
