"But I say that so long as the heir is a child, he differeth nothing from a bondservant, though he is lord of all; but is under guardians and stewards until the term appointed of the father. So we also, when we were children, were held in bondage under the rudiments of the world: but when the fulness of the time came, God sent forth His Son, born of a woman, born under the law, that He might redeem them which were under the law, that we might receive the adoption of sons. And because ye are sons, God sent forth the Spirit of His Son into our hearts, crying, Abba Father. So that thou art no longer a bondservant, but a son; and if a son, then an heir through God."--GAL. iv. 1-7.
The main thesis of the Epistle is now established. Gentile Christians, Paul has shown, are in the true Abrahamic succession of faith. And this devolution of the Promise discloses the real intent of the Mosaic law, as an intermediate and disciplinary system. Christ was the heir of Abraham's testament; He was therefore the end of Moses' law. And those who are Christ's inherit the blessings of the Promise, while they escape the curse and condemnation of the Law. The remainder of the Apostle's polemic, down to ch. v. 12, is devoted to the illustration and enforcement of this position.
In this, as in the previous chapter, the pre-Christian state is assigned to the Jew, who was the chief subject of Divine teaching in the former dispensation; it is set forth under the first person (ver. 3), in the language of recollection. Describing the opposite condition of sonship, the Apostle reverts from the first to the second person, identifying his readers with himself (comp. ch. iii. 25, 26). True, the Gentiles had been in bondage (vv. 7, 8). This goes without saying. Paul's object is to show that _Judaism_ is a bondage. Upon this he insists with all the emphasis he can command. Moreover, the legal system contained worldly, unspiritual elements, crude and childish conceptions of truth, marking it, in comparison with Christianity, as an inferior religion. Let the Galatians be convinced of this, and they will understand what Paul is going to say directly; they will perceive that Judaic conformity is for them a backsliding in the direction of their former heathenism (vv. 8-10). But the force of this latter warning is discounted and its effect weakened when he is supposed, as by some interpreters, to include _Gentile_ along with Jewish "rudiments" already in ver. 3. His readers could not have suspected this. The "So we also" and the "held in bondage" of this verse carry them back to ch. iii. 23. By calling the Mosaic ceremonies "rudiments of _the world_" he gives Jewish susceptibilities just such a shock as prepares for the declaration of ver. 9, which puts them on a level with heathen rites.
The difference between Judaism and Christianity, historically unfolded in ch. iii., is here restated in graphic summary. We see, first, _the heir of God in his minority_; and again, _the same heir in possession of his estate_.
I. One can fancy the Jew replying to Paul's previous argument in some such style as this. "You pour contempt," he would say, "on the religion of your fathers. You make them out to have been no better than slaves. Abraham's inheritance, you pretend, under the Mosaic dispensation lay dormant, and is revived in order to be taken from his children and conferred on aliens." No, Paul would answer: I admit that the saints of Israel were sons of God; I glory in the fact--"who are Israelites, whose is _the adoption of sons_ and the glory and the covenants and the law-giving and the promises, whose are the fathers" (Rom. ix. 4, 5). _But they were sons in their minority._ "And I say that as long as the heir is (legally) an infant, he differs in nothing from a slave, though (by title) lord of all."
