8:7-13 Eating one kind of food, and abstaining from another, have nothing in them to recommend a person to God. But the apostle cautions against putting a stumbling-block in the way of the weak; lest they be made bold to eat what was offered to the idol, not as common food, but as a sacrifice, and thereby be guilty of idolatry. He who has the Spirit of Christ in him, will love those whom Christ loved so as to die for them. Injuries done to Christians, are done to Christ; but most of all, the entangling them in guilt: wounding their consciences, is wounding him. We should be very tender of doing any thing that may occasion stumbling to others, though it may be innocent in itself. And if we must not endanger other men's souls, how much should we take care not to destroy our own! Let Christians beware of approaching the brink of evil, or the appearance of it, though many do this in public matters, for which perhaps they plead plausibly. Men cannot thus sin against their brethren, without offending Christ, and endangering their own souls.
11. shall … perish—The oldest manuscripts read "perisheth." A single act seemingly unimportant may produce everlasting consequences. The weak brother loses his faith, and if he do not recover it, his salvation [Bengel] (Ro 14:23).
for whom Christ died—and for whose sake we too ought to be willing to die (1Jo 3:16). And yet professing Christians at Corinth virtually tempted their brethren to their damnation, so far were they from sacrificing aught for their salvation. Note here, that it is no argument against the dogma that Christ died for all, even for those who perish, to say that thus He would have died in vain for many. Scripture is our rule, not our suppositions as to consequences. More is involved in redemption than the salvation of man: the character of God as at once just and loving is vindicated even in the case of the lost for they might have been saved, and so even in their case Christ has not died in vain. So the mercies of God's providence are not in vain, though many abuse them. Even the condemned shall manifest God's love in the great day, in that they too had the offer of God's mercy. It shall be the most awful ingredient in their cup that they might have been saved but would not: Christ died to redeem even them.
