John Calvin Commentary Galatians 3:23

"But before faith came, we were kept in ward under the law, shut up unto the faith which should afterwards be revealed." — Galatians 3:23 (ASV)

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 temporary; 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 is but one church consisting of Jews and Gentiles, why is there a diversity in its government? From where 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 that it does not interrupt the union and harmony of the church.

We must again remind the reader that Paul does not deal exclusively with ceremonies, or with the moral law, but embraces the whole administration 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 to our attention, 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 a designation given here, 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, so that they might not wander from the fold of faith, it kept them in its custody.

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 side 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 lacked 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 should 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 until 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.
