(12) When ye sin so.--When you sin in this way--and he explains further what the sin is: "Striking a blow upon their weak consciences"--you sin against Christ. You wound a member of that body which is His. (See Matthew 25:40.)

Verse 12. - And wound their weak conscience; rather, and in smiting their conseience which is weak. "What," asks St. Chrysostom, "can be more ruthless than a man who strikes one who is sick?" Was it not a cowardly exercise of liberty to strike the conscience of the defenceless? It is another form of "defiling" (ver. 7) the conscience, but brings out the cruelty of such conduct. Ye sin against Christ. Because Christ lives and suffers in the persons of the least of his little ones (Matthew 25:40, 45; Romans 12:5, etc.).

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.But when ye sin so against the brethren,.... Through sitting at meat in an idol's temple, and thereby violating the new commandment of love; by which saints are obliged to love one another as brethren, and take care to do nothing that may hurt and prejudice one another's peace and comfort, it being an incumbent duty upon them by love to serve one another: and

wound their weak conscience: as before observed: it is contrary to the law of love to wound a brother; it is an aggravation of the sin to wound a weak one; what greater cruelty than to strike or beat, as the word here used signifies, a sick and infirm man? and greater still to strike and wound his conscience than any part of his body; for a wounded spirit is insupportable without divine aid and influence; and what serves most to enhance the crime and guilt is,

ye sin against Christ, who has so loved this weak brother as to die for him; and between whom there is so close an union, as between head and members; and from whence such a sympathy arises, that what is done to or against such a person, Christ takes as done to himself. The Syriac version emphatically adds, "himself".
