7 In strict logic, then, nothing happened to the meat when it was offered up to an idol. It's just like any other meat. I know that, and you know that. But knowing isn't everything. If it becomes everything, some people end up as know-it-alls who treat others as know-nothings. Real knowledge isn't that insensitive. We need to be sensitive to the fact that we're not all at the same level of understanding in this. Some of you have spent your entire lives eating "idol meat," and are sure that there's something bad in the meat that then becomes something bad inside of you. An imagination and conscience shaped under those conditions isn't going to change overnight.
Matthew Henry's Commentary on 1 Corinthians 8:7
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.
