23. Before faith came. The question proposed is now more fully defined. He explains at great length the use of the law, and the reason why it was temporal; for otherwise it would have appeared to be always unreasonable that a law should be delivered to the Jews, from which the Gentiles were excluded. If there be but one church consisting of Jews and Gentiles, why is there a diversity in its government? Whence is this new liberty derived, and on what authority does it rest, since the fathers were under subjection to the law? He therefore informs us, that the distinction is such as not to interrupt the union and harmony of the church.

We must again remind the reader that Paul does not treat exclusively of ceremonies, or of the moral law, but embraces the whole economy by which the Lord governed his people under the Old Testament. It became a subject of dispute whether the form of government instituted by Moses had any influence in obtaining righteousness. Paul compares this law first to a prison, and next to a schoolmaster. Such was the nature of the law, as both comparisons plainly show, that it could not have been in force beyond a certain time.

Faith denotes the full revelation of those things which, during the darkness of the shadows of the law, were dimly seen; for he does not intend to say that the fathers, who lived under the law, did not possess faith. The faith of Abraham has already come under our notice, and other instances are quoted by the author of the Epistle to the Hebrews. (Hebrews 11.) The doctrine of faith, in short, is attested by Moses and all the prophets: but, as faith was not then clearly manifested, so the time of faith is an appellation here given, not in an absolute, but in a comparative sense, to the time of the New Testament. That this was his meaning is evident from what he immediately adds, that they were shut up under the faith which should afterwards be revealed; for this implies that those who were under the custody of the law were partakers of the same faith. The law did not restrain them from faith; but, that they might not wander from the fold of faith, it kept possession of themselves. There is an elegant allusion, too, to what he had formerly said, that “the scripture hath concluded all under sin.” They were besieged on every hand by the curse, but this siege was counteracted by an imprisonment which protected them from the curse; so that the imprisonment by the law is here proved to have been highly generous in its character.

Faith was not yet revealed, not because the fathers wanted light, but because they had less light than we have. The ceremonies might be said to shadow out an absent Christ, but to us he is represented as actually present, and thus while they had the mirror, we have the substance. Whatever might be the amount of darkness under the law, the fathers were not ignorant of the road in which they ought to walk. Though the dawn is not equal to the splendor of noon, yet, as it is sufficient to direct a journey, travelers do not wait till the sun is fully risen. Their portion of light resembled the dawn, which was enough to preserve them from all error, and guide them to everlasting blessedness.

24. Wherefore the law was our schoolmaster This is the second comparison, which still more clearly expresses Paul’s design. A schoolmaster is not appointed for the whole life, but only for childhood, as the etymology of the Greek word παιδαγωγός implies. ⁶³⁶³     “As the law was before compared to a jailer, so it is here likened to a παιδαγωγός, by which term is not to be understood a schoolmaster, (for that would have been διδάσκαλος,) but the paedagous or person (usually a freedman or slave) who conducted children to and from school, attended them out of school hours, formed their manners, superintended their moral conduct, and in various respects prepared them for the διδάσκαλος.” — Bloomfield. Our author’s observations on παιδαγωγός, in another passage, have brought out the full meaning of this word, and the classical authorities for the use of it, in the translator’s notes. — Calvin on the Corinthians, vol. 1, p. 169. — Ed Besides, in training a child, the object is to prepare him, by the instructions of childhood, for maturer years. The comparison applies in both respects to the law, for its authority was limited to a particular age, and its whole object was to prepare its scholars in such a manner, that, when its elementary instructions were closed, they might make progress worthy of manhood. And so he adds, that it was our schoolmaster (εἰς Χριστὸν) unto Christ. The grammarian, when he has trained a boy, delivers him into the hands of another, who conducts him through the higher branches of a finished education. In like manner, the law was the grammar of theology, which, after carrying its scholars a short way, handed them over to faith to be completed. Thus, Paul compares the Jews to children, and us to advanced youth.

But a question arises, what was the instruction or education of this schoolmaster? First, the law, by displaying the justice of God, convinced them that in themselves they were unrighteous; for in the commandments of God, as in a mirror, they might see how far they were distant from true righteousness. They were thus reminded that righteousness must be sought in some other quarter. The promises of the law served the same purpose, and might lead to such reflections as these: “If you cannot obtain life by works but by fulfilling the law, some new and different method must be sought. Your weakness will never allow you to ascend so high; nay, though you desire and strive ever so much, you will fall far short of the object.” The threatenings, on the other hand, pressed and entreated them to seek refuge from the wrath and curse of God, and gave them no rest till they were constrained to seek the grace of Christ.

Such too, was the tendency of all the ceremonies; for what end did sacrifices and washings serve but to keep the mind continually fixed on pollution and condemnation? When a man’s uncleanness is placed before his eyes, when the unoffending animal is held forth as the image of his own death, how can he indulge in sleep? How can he but be roused to the earnest cry for deliverance? Beyond all doubt, ceremonies accomplished their object, not merely by alarming and humbling the conscience, but by exciting them to the faith of the coming Redeemer. In the imposing services of the Mosaic ritual, every thing that was presented to the eye bore an impress of Christ. The law, in short, was nothing else than an immense variety of exercises, in which the worshippers were led by the hand to Christ.

That we might be justified by faith. He has already said that the law is not perfect, when he compared it to the training of childhood; but it would make men perfect if it bestowed upon them righteousness. What remains but that faith shall take its place? And so it does, when we, who are destitute of a righteousness of our own, are clothed by it with the righteousness of Christ. Thus is the saying accomplished, “he hath filled the hungry with good things.” (Luke 1:53.)

25. But after that faith is come. This phrase has been already considered. It denotes the brighter revelation of grace after that “the vail of the temple was rent in twain,” (Matthew 27:51,) which, we know, was effected by the manifestation of Christ. He affirms that, under the reign of Christ, there is no longer any childhood which needs to be placed under a schoolmaster, and that, consequently, the law has resigned its office, — which is another application of the comparison. There were two things which he had undertaken to prove, — that the law is a preparation for Christ, and that it is temporal. But here the question is again put, Is the law so abolished that we have nothing to do with it? I answer, the law, so far as it is a rule of life, a bridle to keep us in the fear of the Lord, a spur to correct the sluggishness of our flesh, — so far, in short, as it is

“profitable for doctrine, for reproof, for correction, for instruction in righteousness, that believers may be instructed in every good work,” (2 Timothy 3:16, 17,)

— is as much in force as ever, and remains untouched.

In what respect, then, is it abolished? Paul, we have said, looks at the law as possessing certain qualities, and those qualities we shall enumerate. It annexes to works a reward and a punishment; that is, it promises life to those who keep it, and curses all transgressors. Meanwhile, it requires from man the highest perfection and most exact obedience. It makes no abatement, gives no pardon, but calls to a severe reckoning the smallest offenses. It does not openly exhibit Christ and his grace, but points him out at a distance, and only when hidden by the covering of ceremonies. All such qualities of the law, Paul tells us, are abolished; so that the office of Moses is now at an end, so far as it differs in outward aspect from a covenant of grace.

26. For ye are all the children of God. It would be unjust, and in the highest degree unreasonable, that the law should hold believers in perpetual slavery. This is proved by the additional argument, that they are the children of God. It would not be enough to say that we are no longer children, unless it were added that we are freemen; for in slaves age makes no alteration. The fact of their being the children of God proves their freedom. How? By faith in Christ Jesus; for

“as many as received him, to them gave he power to become the sons of God, even to them that believe on his name.”
(John 1:12.)

Since, then, by faith we have obtained adoption, by faith likewise we have obtained our freedom.
