But after that faith is come - The scheme of salvation by faith. After that is revealed; see the note at Galatians 3:23.

We are no longer under a schoolmaster - Under the poedagogus, or pedagogue. We are not kept in restraint, and under bondage, and led along to another to receive instruction. We are directly under the great Teacher, the Instructor himself; and have a kind of freedom which we were not allowed before. The bondage and servitude have passed away; and we are free from the burdensome ceremonies and expensive rites (compare the note at Acts 15:10) of the Jewish law, and from the sense of condemnation which it imposes. This was true of the converts from Judaism to Christianity - that they became free from the burdensome rites of the Law and it is true of all converts to the faith of Christ, that, having been made to see their sin by the Law, and having been conducted by it to the cross of the Redeemer, they are now made free.

But, after that faith is come - When Christ was manifested in the flesh, and the Gospel was preached, we were no longer under the pedagogue; we came to Christ, learned of him, became wise unto salvation, had our fruit unto holiness, and the end eternal life.

It is worthy of remark that, as ὁ νομος, the Law, is used by St. Paul to signify, not only the law, properly so called, but the whole of the Mosaic economy, so ἡ πιστις, the Faith, is used by him to express, not merely the act of believing in Christ, but the whole of the Gospel.

But after that faith is come,.... That is, since Christ the object of faith is come in the flesh, and has fulfilled the law, and redeemed them that were under it from its bondage, curse, and condemnation:

we are no longer under a schoolmaster; under the law as such; as no longer under it as a military guard, nor in it as a prison, so neither under it as a schoolmaster; not needing its instructions, or its discipline; since Christ is come as a prophet to teach and instruct, as a priest to atone for sin, and make intercession for transgressors, and as a King to rule and govern; in whose hands, and not in the hands of Moses, the law now is, as a rule of walk and conversation.

But after that faith is come, we are no longer under a schoolmaster.

3:25 But after that faith is come, we are no longer under a schoolmaster. When once brought to Christ we do not need the tutor any longer. We are no longer under him.

3:25 But faith - That is, the gospel dispensation. Being come, we are no longer under that schoolmaster - The Mosaic dispensation.

[1] schoolmaster

Gr. paidagogos, "child-conductor." "among the Greeks and Romans, persons, for the most part slaves, who had it in charge to educate and give constant attendance upon boys till they came of age."--H.A.W. Meyer. The argument does not turn upon the extent or nature of the pedagogue's authority, but upon the fact that it wholly ceased when the "child" Gal 4:1 became a Song 1:1 Gal 4:1-6 when the minor became an adult. The adult "son" does voluntarily that which formerly he did in fear of the pedagogue. But even if he does not, it is no longer a question between the son and the pedagogue (the law), but between the son and his Father--God. (Cf) Heb 12:5-10 1Jn 2:1,2.

25. "But now that faith is come," &c. Moses the lawgiver cannot bring us into the heavenly Canaan though he can bring us to the border of it. At that point he is superseded by Joshua, the type of Jesus, who leads the true Israel into their inheritance. The law leads us to Christ, and there its office ceases.

3:23-25 The law did not teach a living, saving knowledge; but, by its rites and ceremonies, especially by its sacrifices, it pointed to Christ, that they might be justified by faith. And thus it was, as the word properly signifies, a servant, to lead to Christ, as children are led to school by servants who have the care of them, that they might be more fully taught by Him the true way of justification and salvation, which is only by faith in Christ. And the vastly greater advantage of the gospel state is shown, under which we enjoy a clearer discovery of Divine grace and mercy than the Jews of old. Most men continue shut up as in a dark dungeon, in love with their sins, being blinded and lulled asleep by Satan, through wordly pleasures, interests, and pursuits. But the awakened sinner discovers his dreadful condition. Then he feels that the mercy and grace of God form his only hope. And the terrors of the law are often used by the convincing Spirit, to show the sinner his need of Christ, to bring him to rely on his sufferings and merits, that he may be justified by faith. Then the law, by the teaching of the Holy Spirit, becomes his loved rule of duty, and his standard for daily self-examination. In this use of it he learns to depend more simply on the Saviour.
