28. He that despised, etc. This is an argument from the less to the greater; for if it was a capital offense to violate the law of Moses, how much heavier punishment does the rejection of the gospel deserve, a sin which involves so many and so heinous impieties! This reasoning was indeed most fitted to impress the Jews; for so severe a punishment on apostates under the Law was neither new to them, nor could it appear unjustly rigorous. They ought then to have acknowledged that vengeance just, however severe, by which God now sanctions the majesty of his Gospel¹.

Hereby is also confirmed what I have already said, that the Apostle speaks not of particular sins, but of the entire denial of Christ; for the Law did not punish all kinds of transgressions with death, but apostasy, that is, when any one wholly renounced religion; for the Apostle referred to a passage in Deuteronomy 17:2-7, ² where we find, that if any one violated God's covenant by worshipping foreign gods, he was to be brought outside of the gate and stoned to death.

Now, though the Law proceeded from God, and Moses was not its author, but its minister, yet the Apostle calls it the law of Moses, because it had been given through him: this was said in order to amplify the more the dignity of the Gospel, which has been delivered to us by the Son of God.

Under two or three witnesses, etc. This bears not on the present subject; but it was a part of the civil law of Moses that two or three witnesses were required to prove the accused guilty. However, we hence learn what sort of crime the Apostle meant; for had not this been added, an opening would have been left for many false conjectures. But now it is beyond all dispute that he speaks of apostasy. At the same time that equity ought to be observed which almost all statesmen have adopted, that no one is to be condemned without being proved guilty by the testimony of two witnesses. ³

29. Who has trodden under foot the Son of God, etc. There is this likeness between apostates under the Law and under the Gospel, that both perish without mercy; but the kind of death is different; for the Apostle denounces on the despisers of Christ not only the deaths of the body, but eternal perdition. And therefore he says that a sorer punishment awaits them. And he designates the desertion of Christianity by three things; for he says that thus the Son of God is trodden under foot, that his blood is counted an unholy thing, and that despite is done to the Spirit of grace. Now, it is a more heinous thing to tread under foot than to despise or reject; and the dignity of Christ is far different from that of Moses; and further, he does not simply set the Gospel in opposition to the Law, but the person of Christ and of the Holy Spirit to the person of Moses.

The blood of the covenant, etc. He enhances ingratitude by a comparison with the benefits. It is the greatest indignity to count the blood of Christ unholy, by which our holiness is effected; this is done by those who depart from the faith. For our faith looks not on the naked doctrine, but on the blood by which our salvation has been ratified. He calls it the blood of the covenant, because then only were the promises made sure to us when this pledge was added. But he points out the manner of this confirmation by saying that we are sanctified; for the blood shed would avail us nothing, except we were sprinkled with it by the Holy Spirit; and hence come our expiation and sanctification. The apostle at the same time alludes to the ancient rite of sprinkling, which availed not to real sanctification, but was only its shadow or image.⁴

The Spirit of grace. He calls it the Spirit of grace from the effects produced; for it is by the Spirit and through his influence that we receive the grace offered to us in Christ. For he it is who enlightens our minds by faith, who seals the adoption of God on our hearts, who regenerates us unto newness of life, who grafts us into the body of Christ, that he may live in us and we in him. He is therefore rightly called the Spirit of grace, by whom Christ becomes ours with all his blessings. But to do despite to him, or to treat him with scorn, by whom we are endowed with so many benefits, is an impiety extremely wicked. Hence learn that all who willfully render useless his grace, by which they had been favored, act disdainfully towards the Spirit of God.

It is therefore no wonder that God so severely visits blasphemies of this kind; it is no wonder that he shows himself inexorable towards those who tread under foot Christ the Mediator, who alone reconciles us to himself; it is no wonder that he closes up the way of salvation against those who spurn the Holy Spirit, the only true guide.⁵

30. For we know him that hath said, etc. Both the passages are taken from Deuteronomy 32:35, 36. But as Moses there promises that God would take vengeance for the wrongs done to his people, it seems that the words are improperly and constrainedly applied to the vengeance referred to here; for what does the Apostle speak of? Even that the impiety of those who despised God would not be unpunished. Paul also in Romans 12:19, knowing the true sense of the passage, accommodates it to another purpose; for having in view to exhort us to patience, he bids us to give place to God to take vengeance, because this office belongs to him; and this he proves by the testimony of Moses. But there is no reason why we should not turn a special declaration to a universal truth. Though then the design of Moses was to console the faithful, as they would have God as the avenger of wrongs done to them; yet we may always conclude from his words that it is the peculiar office of God to take vengeance on the ungodly. Nor does he pervert his testimony who hence proves that the contempt of God will not be unpunished; for he is a righteous judge who claims to himself the office of taking vengeance.

At the same time the Apostle might here also reason from the less to the greater, and in this manner: "God says that he will not suffer his people to be injured with impunity, and declares that he will surely be their avenger: If he suffers not wrongs done to men to be unpunished, will he not avenge his own? Has he so little or no care and concern for his own glory, as to connive at and pass by indignities offered to him?" But the former view is more simple and natural, -- that the Apostle only shows that God will not be mocked with impunity, since it is his peculiar office to render to the ungodly what they have deserved.⁶

The Lord shall judge his people. Here another and a greater difficulty arises; for the meaning of Moses seems not to agree with what here intended. The Apostle seems to have quoted this passage as though Moses had used the word punish, and not judge; but as it immediately follows by way of explanation, "He will be merciful to his saints," it appears evident that to judge here is to act as a governor, according to its frequent meaning in the Hebrew; but this seems to have little to do with the present subject. Nevertheless he who weighs well all things will find that this passage is fitly and suitably adduced here; for God cannot govern the Church without purifying it, and without restoring to order the confusion that may be in it. Therefore this governing ought justly to be dreaded by hypocrites, who will then be punished for usurping a place among the faithful, and for perfidiously using the sacred name of God, when the master of the family undertakes himself the care of setting in order his own house. It is in this sense that God is said to arise to judge his people, that is, when he separates the truly godly from hypocrites, (Psalm 1:4;) and in Psalm 125:5, ⁷ where the Prophet speaks of exterminating hypocrites, that they might no more dare to boast that they were of the Church, because God bore with them; he promises peace to Israel after having executed his judgment.

It was not then unreasonably that the apostle reminded them that God presided over his Church and omitted nothing necessary for its rightful government, in order that they might all learn carefully to keep themselves under his power, and remember that they had to render an account to their judge.⁸

He hence concludes that it is a fearful thing to fall into the hands of the living God. A mortal man, however incensed he may be, cannot carry his vengeance beyond death; but God's power is not bounded by so narrow limits; besides, we often escape from men, but we cannot escape from God's judgment. Who soever then considers that he has to do with God, must (except he be extremely stupid) really tremble and quake; nay, such an apprehension of God must necessarily absorb the whole man, so that no sorrows, or torments can be compared with it. In short, whenever our flesh allures us or we flatter ourselves by any means in our sins, this admonition alone ought to be sufficient to arouse us, that "it is a fearful thing to fall into to hands of the living God;" for his wrath is furnished with dreadful punishments which are to be forever.

However, the saying of David, when he exclaimed, that it was better to fall into Gods hands than into the hands of men, (2 Samuel 24:14,) seems to be inconsistent with what is said here. But this apparent inconsistency vanishes, when we consider that David, relying confidently on God's mercy, chose him as his Judge rather than men; for though he knew that God was displeased with him, yet he felt confident that he would be reconciled to him; in himself, indeed, he was prostrate on the ground, but yet he was raised up by the promise of grace. As then he believed God not to be inexorable, there is no wonder that he dreaded his wrath less, than that of men; but the Apostle here speaks of God's wrath as being dreadful to the reprobate, who being destitute of the hope of pardon, expect nothing but extreme severity, as they have already closed up against themselves the door of grace. And we know that God is set forth in various ways according to the character of those whom he addresses; and this is what David means when he says, "With the merciful thou wilt be merciful, and with the froward thou wilt be froward." (Psalm 18:25-27.) ⁹
