‏ Galatians 3:19-25

Verse 19

Wherefore then serveth the law? - If the law does not annul the Abrahamic covenant, and cannot confer salvation on its votaries, why did God give it? This was a very natural objection, and must arise in the mind of any Jew who had paid attention to the apostle's reasoning.

It was added because of transgressions - It was given that we might know our sinfulness, and the need we stood in of the mercy of God. The law is the right line, the straight edge, that determines the obliquity of our conduct. See the notes on Rom 4:15 (note); and especially on Rom 5:20 (note), where this subject is largely discussed, and the figure explained.

Till the seed should come - The law was to be in force till the advent of the Messiah. After that it was to cease.

It was ordained by angels - The ministry of angels was certainly used in giving the law; see Psa 68:17; Act 7:53; and Heb 2:2; but they were only instruments for transmitting; Moses was the mediator between God and the people, Deu 5:5.
Verse 20

A mediator is not a mediator of one - As a mediator, μεσιτης, signifies a middle person, there must necessarily be two parties, between whom he stands, and acts in reference to both, as he is supposed to have the interests of both equally at heart.

This verse is allowed to be both obscure and difficult; and it is certain that there is little consent among learned men and critics in their opinions concerning it. Rosenmuller thinks that the opinion of Nosselt is to be preferred to all others.

He first translates the words ὁ δε μεσιτης ἑνος ουκ εστιν thus: But he (viz. Moses) is not the mediator of that one race of Abraham, viz. the Christians; for ἑνος relates to the σπερμα ᾡ επηγγελται, the seed that should come, Gal 3:19, of which he said, ὡς εφ' ἑνος, as of one, Gal 3:16. If Paul had written ὁ δε μεσιτης του ἑνος εκεινου ουκ εστι, he is not the mediator of one, no person would have had any doubt that σπερματος, seed, ought to be supplied after ἑνος, of one, Gal 3:19-20. The same mode of speaking Paul uses, Rom 5:17; ὁ δε, but he, ὁ for αυτος, Mat 12:3, Mat 12:11, Mat 12:39, ὁ δε ειπεν, but he said. Though Moses was the Mediator between God and the Israelites, yet he was not the mediator between God and that one seed which was to come; viz. the Gentiles who should believe in Christ.

But God is one - He is the one God, who is the Father of the spirits of all flesh; the God of the Gentiles as well as the God of the Jews. That this is St. Paul's meaning is evident from his use of the same words in other places, 1Tim 2:5 : ἑις γαρ Θεος, etc., for there is one God, and one mediator between God and man, that is, there is only one God and one mediator for the whole human race; Eph 4:5, Eph 4:6 : One Lord, one faith, one baptism, εἱς Θεος και πατηρ παντων, One God and Father of All. The sense of the whole is: Moses was the mediator of one part of Abraham's seed, viz. the Israelites; but of the other seed, the Gentiles, he was certainly not the mediator; for the mediator of that seed, according to the promise of God, and covenant made with Abraham, is Christ.

Though Nosselt has got great credit for this interpretation, it was given in substance long before him by Dr. Whitby, as may be seen in the following words: "But this mediator (Moses) was only the mediator of the Jews, and so was only the mediator of one party, to whom belonged the blessings of Abraham, Gal 3:8, Gal 3:14. But God, who made the promise that in one should all the families of the earth be blessed, Is One; the God of the other party, the Gentiles, as well as of the Jews, επειπερ εἱς ὁ Θεος, seeing he is One God, who will justify the circumcision by faith, and the uncircumcision through faith, Rom 3:30." This exposition is so plain, and so well supported by the different scriptures already quoted, that there can be but small, if any, doubt of its propriety. The clause has been translated thus: "Now a mediator supposes two parties, of which God is but one."
Verse 21

Is the law then against the promises of God? - Is it possible that the intervention of the law, in reference to one part of the Abrahamic seed, should annul the promise made to the other? It is impossible.

For if there had been a law, etc. - If any law or rule of life could have been found out that would have given life - saved sinners from death, and made them truly happy, then righteousness- justification, should have been by that law.
Verse 22

But the scripture hath concluded - All the writings of the prophets have uniformly declared that men are all sinners, and the law declares the same by the continual sacrifices which it prescribes. All, therefore have sinned, and come short of the glory of God; and, being tried and found guilty, συνεκλεισεν ἡ γραφη, the Scripture hath shut them up - put them in prison, and locked them up, till the time should come in which the sentence of the law should be executed upon them: (See Rom 3:9-20, and the notes there; and particularly Rom 11:32 (note), where the apostle uses the same metaphor, and which in the note is particularly explained.) That the promise of justification, by faith of Jesus Christ, might be given to them that believe.
Verse 23

But before faith came - Before the Gospel was published.

We were kept under the law, shut up - Εφρουρουμεθα· We were kept as in a strong hold, συγκεκλεισμενοι, locked up, unto the faith - the religion of the Lord Jesus, which should afterwards be revealed. Here the same metaphor is used as above, and for its explanation I must refer the reader to the same place, Rom 11:32 (note).
Verse 24

The law was our schoolmaster - Ὁ νομος παιδαγωγος ἡμων γεγονεν εις Χριστον· The law was our pedagogue unto Christ. The παιδαγωγος, pedagogue, is not the schoolmaster, but the servant who had the care of the children to lead them to and bring them back from school, and had the care of them out of school hours. Thus the law did not teach us the living, saving knowledge; but, by its rites and ceremonies, and especially by its sacrifices, it directed us to Christ, that we might be justified by faith. This is a beautiful metaphor, and highly illustrative of the apostle's doctrine. See the note on Rom 10:4, where this figure is farther explained.
Verse 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.
