11. Our mouth is opened. As the opening of the mouth is a sign of boldness, ³ if you are inclined to connect this with what goes before, the meaning will be this, -- "I have ample ground of glorying, and an upright conscience opens my mouth. Your entertaining unfavorable views of us, is not owing to any fault on our part, but arises from your being unfair judges. For you ought to have entertained more favorable views of my ministry, which God has rendered honorable to you in so many ways." I explain it, however, otherwise; for he says that the reason why his mouth was opened was, that his heart was enlarged. Now what is meant by enlargement of heart? Undoubtedly it means the cheerfulness that springs from benevolence. ⁴ It is quite a common figure, to speak of a narrow and contracted heart as denoting either grief, or disgust, while, on the other hand, an enlarged heart is employed to denote dispositions of an opposite kind. Hence Paul here says nothing but what we every day experience, for when we have to do with friends, our heart is enlarged, all our feelings are laid open, there is nothing there that is hid, nothing shut, -- nay more, the whole mind leaps and exults to unfold itself openly to view. ⁵ Hence it is, that the tongue, also, is free and unfettered, does not faulter, does not with difficulty draw up from the bottom of the throat broken syllables, as usually happens when the mind is influenced by a less joyful affection.

12. Ye are not straitened in us. That is, "It is owing to your own fault that you are not able to share in this feeling of cheerfulness, which I entertain towards you. My mouth is opened, so that I deal familiarly with you, my very heart would willingly pour itself forth, ⁶ but you shut up your bowels." He means to say, that it is owing to their corrupt judgment, that the things that he utters are not relished by them.

13. Now the same requital. He softens his reproof by addressing them kindly as his sons, and also by this exhortation, by which he intimates that he still entertains good hopes of them. By the same requital he means -- mutual duty, for there is a mutual return of duty between a father and his sons. For as it is the duty of parents to nourish their children, to instruct them, to direct them by their counsel, and to defend them, so it is the dictate of equity, that children should requite their parents. (1 Timothy 6:4.) In fine, he means what the Greeks call ajntipelargi>an -- affection exercised in return. ⁷ "I cherish," says he, "towards you paternal affection: show yourselves then to be my sons by affection and respect in return." At the same time there is a particular circumstance that must be noticed, That the Corinthians, having found so indulgent a father, may also show gentleness in their turn, and may requite his kind condescension by their docility, he exhorts them with this view to be enlarged in their own bowels. The Old Interpreter, not having caught Paul's meaning, has added the participle having, and has thus expressed his own view rather than Paul's. In our exposition, on the other hand, (which is Chrysostom's, also,) there is nothing forced. ⁸

14. Be not yoked. As if regaining his authority, he now reproves them more freely, because they associated with unbelievers, as partakers with them in outward idolatry. For he has exhorted them to show themselves docile to him as to a father: he now, in accordance with the rights that belong to him, ⁹ reproves the fault into which they had fallen. Now we mentioned in the former epistle ¹⁰ what this fault was; for, as they imagined that there was nothing that was unlawful for them in outward things, they defiled themselves with wicked superstitions without any reserve. For in frequenting the banquets of unbelievers, they participated along with them in profane and impure rites, and while they sinned grievously, they nevertheless thought themselves innocent. On this account Paul inveighs here against outward idolatry, and exhorts Christians to stand aloof from it, and have no connection with it. He begins, however, with a general statement, with the view of coming down from that to a particular instance, for to be yoked with unbelievers means nothing less than to

have fellowship with the unfruitful works of darkness,
(Ephesians 5:11,)

and to hold out the hand to them ¹¹ in token of agreement.

Many are of opinion that he speaks of marriage, but the context clearly shows that they are mistaken. The word that Paul makes use of means -- to be connected together in drawing the same yoke. It is a metaphor taken from oxen or horses, which require to walk at the same pace, and to act together in the same work, when fastened under one yoke. ¹² When, therefore, he prohibits us from having partnership with unbelievers in drawing the same yoke, he means simply this, that we should have no fellowship with them in their pollutions. For one sun shines upon us, we eat of the same bread, we breathe the same air, and we cannot altogether refrain from intercourse with them; but Paul speaks of the yoke of impiety, that is, of participation in works, in which Christians cannot lawfully have fellowship. On this principle marriage will also be prohibited, inasmuch as it is a snare, by which both men and women are entangled into an agreement with impiety; but what I mean is simply this, that Paul's doctrine is of too general a nature to be restricted to marriage exclusively, for he is discoursing here as to the shunning of idolatry, on which account, also, we are prohibited from contracting marriages with the wicked.

For what fellowship. He confirms his exhortation on the ground of its being an absurd, and, as it were, monstrous connecting together of things in themselves much at variance; for these things can no more coalesce than fire and water. In short it comes to this, that unless they would have everything thrown into confusion, they must refrain from the pollutions of the wicked. Hence, too, we infer, that even those that do not in their hearts approve of superstitions are, nevertheless, polluted by dissimulation if they do not openly and ingenuously stand aloof from them.

15. What concord has Christ with Belial? As to the etymology of the word Belial, even the Hebrews themselves are not agreed ¹³ The meaning, however, is not doubtful. ¹⁴ For Moses takes a word or thought of Belial ¹⁵ to mean a wicked and base thought, ¹⁶ and in various instances ¹⁷ those who are wicked and abandoned to iniquity, are called men, or sons of Belial. (Deuteronomy 13:13; Judges 19:22; 1 Samuel 2:12.) Hence it is, that Paul has employed the word here to mean the devil, the head of all wicked persons. For from what holds good as to the two heads, he comes down without delay to the members: "As there is an irreconcilable variance between Christ and Satan, so we also must keep aloof from partnership with the wicked." When, however, Paul says that a Christian has no participation with an unbeliever, he does not mean as to food, clothing, estates, the sun, the air, as I have mentioned above, but as to those things that are peculiar to unbelievers, from which the Lord has separated us.

16. What agreement hath the temple of God with idols? Hitherto he has in general terms prohibited believers from associating with the wicked. He now lets them know what was the chief reason, why he had prohibited them from such an association -- because they had ceased to reckon the profession of idolatry to be a sin. He had censured that liberty, and had exposed it at great length in the former Epistle. It is probable, however, that all had not yet been gained over, so as to receive the counsel which he had given. Hence it was that he complained of their being straitened in their own bowels -- the only thing that hindered their proficiency. ¹⁸ He does not, however, resume that subject anew, but contents himself with a short admonition, as we are accustomed to do, when we treat of things that are well known. At the same time his brevity does not prevent his giving sharp cuts. For how much emphasis there is in that single word, where he teaches that there is no agreement between the temple of God and idols! "It is a sacrilegious profanation, ¹⁹ when an idol or any idolatrous service is introduced into the temple of God. Now we are the true temples of God. Hence it is sacrilege to defile ourselves with any contamination of idols. This one consideration, I say, should be to you as good as a thousand. If you are a Christian, what have you to do with idols, (Hosea 14:8,) for you are the temple of God?" Paul, however, as I have already in part noticed, contends rather by way of exhortation than of doctrine, inasmuch as it would have been superfluous to be still treating of it, as if it were a thing doubtful or obscure.

As God saith, I will walk. He proves that we are the temples of God from this, that God of old promised to the people of Israel that he would dwell in the midst of them. In the first place, God cannot dwell among us, without dwelling in each one of us, for he promises this as a singular privilege -- I will dwell in the midst of you. Nor does this dwelling or presence consist merely in earthly blessings, but must be understood chiefly of spiritual grace. Hence it does not mean simply that God is near us, as though he were in the air, flying round about us, but it means rather that he has his abode in our hearts. If, then, any one objects, that the particle in simply means among, I grant it; but I affirm that, from the circumstance that God promises that he will dwell among us, we may infer that he also remains in us. ²⁰ And such was the type of the ark, of which mention is made by Moses in that passage, from which Paul appears to have borrowed this quotation. (Leviticus 26:12.) If, however, any one thinks that Paul had rather in his eye Ezekiel 37:27, the argument will be the same. For the Prophet, when describing the restoration of the Church, mentions as the chief good, the presence of God, which he had himself in the beginning promised by Moses. Now what was prefigured by the ark, was manifested to us more fully in Christ, when he became to us Immanuel ²¹ (Matthew 1:23.) On this account, I am of opinion that it is Ezekiel, rather than Moses, that is here quoted, because Ezekiel alludes at the same time to the type of the ark, and declares that it will have its fulfillment under the reign of Christ. Now the Apostle takes it for granted, that God dwells nowhere but in a sacred place. If we say of a man, "he dwells here," that will not make the place a temple; but as to God there is this peculiarity, that whatever place he honors with his presence, he at the same time sanctifies.

17. Wherefore come out from the midst of them. This exhortation is taken from Isaiah 52:11, where the Prophet, when foretelling the deliverance, at length addresses the priests in these terms. For he makes use of a circumlocution to describe the priests, when he says, Ye that bear the vessels of the Lord, inasmuch as they had the charge of the vessels, by means of which the sacrifices, and other parts of divine worship, were performed. There can be no doubt that his design is to admonish them, that, while eagerly desirous to come forth, ²² they should be on their guard against any contamination from the many pollutions with which the country ²³ was overrun. Now this is no less applicable to us, than to the ancient Levites, for if so much purity is required on the part of the keepers of the vessels, how much more in the vessels themselves! ²⁴ Now all our members are vessels, set apart for the spiritual worship of God; we are also a royal priesthood. (1 Peter 2:9.) Hence, as we are redeemed by the grace of God, it is befitting that we keep ourselves undefiled in respect of all uncleanness, that we may not pollute the sanctuary of God. As, however, while remaining in this world, we are nevertheless redeemed, and rescued, from the pollutions of the world, so we are not to quit life with the view of departing from all uncleanness, but must simply avoid all participation. The sum is this. "If with a true affection of the heart, we aim at the benefit of redemption, we must beware of defiling ourselves by any contamination from its pollutions."

18. I will be a Father unto you. This promise does not occur in one passage merely, but is repeated in various instances. Paul has added it with this view, that a recognition of the great honor to which God has exalted us, might be a motive to stir us up to a more ardent desire for holiness. For when God has restored his Church which he has gathered from profane nations, their redemption is attended with this fruit, that believers are seen to be his sons and daughters. It is no common honor that we are reckoned among the sons of God: it belongs to us in our turn to take care, that we do not show ourselves to be degenerate children to him. For what injury we do to God, if while we call him father, we defile ourselves with abominations of idols! Hence, the thought of the high distinction to which he has elevated us, ought to whet our desire for holiness and purity.
