7 Still, all men have not that knowledge: but some, being used till now to the image, are conscious that they are taking food which has been offered to the image; and because they are not strong in the faith, their minds are troubled. 8 But God's approval of us is not based on the food we take: if we do not take it we are no worse for it; and if we take it we are no better. 9 But take care that this power of yours does not give cause for trouble to the feeble. 10 For if a man sees you, who have knowledge, taking food as a guest in the house of an image, will it not give him, if he is feeble, the idea that he may take food offered to images? 11 And so, through your knowledge, you are the cause of destruction to your brother, for whom Christ underwent death. 12 And in this way, doing evil to the brothers, and causing trouble to those whose faith is feeble, you are sinning against Christ. 13 For this reason, if food is a cause of trouble to my brother, I will give up taking meat for ever, so that I may not be a cause of trouble to my brother.

Matthew Henry's Commentary on 1 Corinthians 8:7-13

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.
