For God hath concluded them all in (literally, shut them all up into) unbelief (or, disobedience), that he might have mercy upon them all. Chrysostom and other Greek Fathers understood συνέκλεισε to mean only declared them to be unbelieving (or, disobedient), or convicted them of being so.
Thus Chrysostom, τουτέστιν ἤλεγξεν, ἔπεδειξεν ἀπειθοῦντας. So, it may be said, must the verb he understood where St. Paul elsewhere uses it with a similar reference in Galatians 3:22, ἡ γραφὴ being there the nominative to the verb.
But ὁ θεὸς being the nominative here, the more obvious meaning seems to be that the shutting up was God's doing. Some, understanding it so, would soften the expression by explaining that God allowed them to become so shut up.
τὸ συνέκλεισε νοητέον ὅτι τοὺς βουληθέντας ἀπειθεῖν εἴασεν ἀπειθεῖν (Diodorus), But we need not shrink from the plain meaning of the expression, viz. that it was God's own act. He is not thus represented as plunging men into inevitable infidelity, having given them no choice.
As in the case of the hardening spoken of' above, his dealings are judicial; the state into which. they are now by him shut up has not been undeserved. And, further, his ultimate purpose is here distinctly declared to be one of mercy.
The way in which the apostle regards such present judicial dealing as conducive to final mercy appears to be such as this. It is the doctrine of the whole Epistle that salvation is to be attained by man's renouncing his own imagined righteousness, and submitting himself to the righteousness of God.
It conduces to this end that his ἀπειθεία should have its course and consequences; so that, conscience being at length awakened, he may long for deliverance from his hopeless state, and appreciate the offered salvation (see ch.
7.). So the Gentile world was long shut up in its self-induced, but also judicial, ἀπειθεία (Romans 1:18, seq.); that, "the wrath of God" being at length revealed to it from heaven, the "righteousness of God" might also be revealed to it and laid hold of.
In like manner God deals now with the Jews, who still persist in going about to establish their own righteousness instead of submitting themselves to the righteousness of God. He shuts them up for the present in their ἀπειθεία, to the end that at length, after their long judgment, and stirred up by the fulness of the Gentiles coming in, they may feel their need, and accept salvation.
τοὺς πάντας in the concluding clause seems to mean generally all mankind, Jews as well as Gentiles; and ἵνα τοὺς πάντας ἐλεήσῃ (as σωθήσεται was understood above with respect to "all Israel," as suggested by the context and the general drift of the chapter) God's embracing all races of mankind at last in the arms of his mercy by calling them into the Church.
Thus the latter expression is not in itself adducible in support of the doctrine of universalism. Certainly the prospect of a universal triumph of the gospel before the end rises here before the apostle in prophetic vision; and it may be that it carries with it to his mind further glories of eternal salvation for all, casting their rays backward over all past ages, so as to inspire an unbounded hope.
Such a hope, which seems elsewhere intimated (cf. 1 Corinthians 15:24-29; Ephesians 1:9, Ephesians 1:10, Ephesians 1:20-23; Colossians 1:15-20, would justify the glowing rhapsody of admiration and thanksgiving that follows more fully than if we supposed the apostle to contemplate still the eternal perdition of the multitudes who in all the ages have not on earth found mercy.
