Galatians 3:25

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 - 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.

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