That we might receive the adoption. The fathers, under the Old Testament, were certain of their adoption, but did not so fully as yet enjoy their privilege. Adoption, like the phrase, "the redemption of our body," (Romans 8:23,) is here put for actual possession. As, at the last day, we receive the fruit of our redemption, so now we receive the fruit of adoption, of which the holy fathers did not partake before the coming of Christ; and therefore those who now burden the church with an excess of ceremonies, defraud her of the just right of adoption.

To redeem them - By his death as an atoning sacrifice; see the note at Galatians 3:13.
Them that were under the law - Sinners, who had violated the Law, and who were exposed to its dread penalty.
That we might receive the adoption of sons - Be adopted as the sons or the children of God; see John 1:12, note; Romans 8:15, note.

To redeem them - Εξαγορασῃ· To pay down a price for them, and thus buy them off from the necessity of observing circumcision, offering brute sacrifices, performing different ablutions, etc., etc.
That we might receive the adoption of sons - Which adoption we could not obtain by the law; for it is the Gospel only that puts us among the children, and gives us a place in the heavenly family. On the nature of adoption see the notes on Romans 8:15.

To redeem them that were under the law, that we might receive the (e) adoption of sons.
(e) The adoption of the sons of God is from everlasting, but is revealed and shown in the time appointed for it.

To redeem them that were under the law,.... By whom are meant chiefly the Jews, who are elsewhere represented as in and under the law, in distinction from the Gentiles who were without it; see Romans 2:12 the Gentiles indeed, though they were not under the law of Moses, yet were not without law to God, they were under the law of nature. The law was given to Adam as a covenant of works, and not to him as a single person, but as a federal head to all his posterity; hence he sinning, and they in him, they all came under its sentence of condemnation and death, God's elect not excepted, and who are the persons said to be redeemed; for Christ was not sent to redeem all that were under the law; for as all mankind were included in it as a covenant of works made with Adam, and all are transgressors of it, the whole world is pronounced guilty before God by it, and liable to the curse of it; but not all mankind, only some out of every kindred, tongue, people, and nation, are redeemed by Christ, even all the elect, whether among Jews or Gentiles. The chosen among the Jews seem to be here principally designed; the redemption of them, which is the end of Christ's being sent, intends not only a deliverance of them from sin and Satan, and the world, to whom they were in bondage, but from the law under which they were; from the bondage of the ceremonial, and from the curse and condemnation of the moral law:
that we might receive the adoption of children; by which may be meant, both the grace, blessing, and privilege of adoption, and the inheritance adopted to; both are received, and that in consequence of redemption by Christ; and such as receive the one will also receive the other. Adoption, as a blessing of grace, exists before it is received; nor does the reception of it add anything to the thing itself; it was in God's designation from all eternity, who predestinated his chosen ones unto it by Christ, according to the good pleasure of his will; it was provided, laid up, and secured for them in the everlasting covenant; and is part of that grace given them in Christ before the world began; but sin intervening, whereby the law was broken, obstacles were thrown in the way of God's elect receiving and enjoying this privilege in their own persons; wherefore Christ was sent to redeem them from sin and the law, and by so doing remove these obstructions, that so they might receive this privilege in a way consistent with the righteousness and holiness of God, as well as with his grace and goodness: receiving of it shows it to be a gift, a free grace gift, and not owing to any merit of the creature; faith is the hand which receives it, as it does all other blessings, as Christ himself, grace out of his fulness, righteousness, pardon, &c. and has no more causal influence on this than on any of these; faith does not make any the sons of God, or put them among the children; but receives the power, the authority, the privilege from God through Christ, under the witnessings of the spirit of adoption; whereby they become such, and have a right to the heavenly inheritance, which they shall hereafter enjoy.

To--Greek, "That He might redeem."
them . . . under the law--primarily the Jews: but as these were the representative people of the world, the Gentiles, too, are included in the redemption (Galatians 3:13).
receive--The Greek implies the suitableness of the thing as long ago predestined by God. "Receive as something destined or due" (Luke 23:41; 2-John 1:8). Herein God makes of sons of men sons of God, inasmuch as God made of the Son of God the Son of man [AUGUSTINE on Psalm 52].

To redeem those under the law - From the curse of it, and from that low, servile state. That we - Jews who believe. Might receive the adoption - All the privileges of adult sons.
