11 So this weak brother or sister, for whom Christ died, is destroyed by your knowledge.
11 And through thy knowledge shall the weak brother perish, for whom Christ died?
11 And so by your knowledge this weak person is destroyed, the brother for whom Christ died.
11 Christ gave up his life for that person. Wouldn't you at least be willing to give up going to dinner for him - because, as you say, it doesn't really make any difference? But it does make a difference if you hurt your friend terribly, risking his eternal ruin!
11 And because of your knowledge shall the weak brother perish, for whom Christ died?
11 So because of your superior knowledge, a weak believer for whom Christ died will be destroyed.
Matthew Henry's Commentary on 1 Corinthians 8:11
Commentary on 1 Corinthians 8:7-13
(Read 1 Corinthians 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.
