{9} Wherefore, if meat make my brother to offend, I will eat no flesh while the world standeth, lest I make my brother to offend.

(9) The conclusion, which Paul conceives in his own person, that he might not seem to exact that of others which he will not be first subject to himself. I had rather (he says) abstain forever from all types of flesh, then give occasion of sin to any of my brethren. And on a smaller scale, in any certain place or time, I would refuse to eat flesh offered to idols, for my brother's sake.

People's New Testament

8:13 Wherefore, if food maketh my brother to offend. To stumble and fall. Love, in this case, would demand that the meat be given up. The principle applies to many things. Some Christians can, perhaps, go to the theater, or dance, or attend the fairs of our day, where the races are the great feature, or even drink wine or beer, without falling. Others cannot. Yet the example of the strong will lead the weak to engage in them, and hence that example will lead them to spiritual death. The Christian principle, the rule of love, is, If eating meat, or going to the theater, or going to a ball, or attending the fair, or drinking wine or beer, causeth my brother to offend, I will not do these things while the world standeth.

Wesley's Notes

8:13 If meat - Of any kind. Who will follow this example? What preacher or private Christian will abstain from any thing lawful in itself, when it offends a weak brother?

Jamieson-Fausset-Brown Bible Commentary

13. meat-Old English for "food" in general.

make . to offend-Greek, "is a stumbling-block to."

no flesh-In order to ensure my avoiding flesh offered to idols, I would abstain from all kinds of flesh, in order not to be a stumbling-block to my brother.

Matthew Henry's Concise Commentary

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.
