1 Corinthians 8:7

7.But there is not in all that knowledge. He refutes, in a single word, all that he had previously brought forward in their name, showing that it is not enough that they know that what, they do is right, if they have not at the same time a regard to their brethren. When he said above — We know that we all have knowledge, (1 Corinthians 8:1,) he referred to those whom he reproved for abusing their liberty. Now, on the other hand, he calls them to consider, that there are many weak and ignorant persons associated with them, to whom they ought to accommodate themselves. “You have, it is true, a correct judgment in the sight of God, and if you were alone in the world, it would be as lawful for you to eat of things offered to idols, as of any other kinds of food. But consider your brethren, to whom you are debtors. You have knowledge; they are ignorant,. Your actions ought to be regulated not merely according to your knowledge, but also according to their ignorance.” This reply is particularly deserving of notice; for there is nothing to which we are more prone (468) than this, that every one follows his own advantage, to the neglect of that of others. Hence we feel prepared to rest in our own judgment, and do not consider, that the propriety of those works that we do in the sight of men depends not merely on our own conscience, but also on that of our brethren.

Some with conscience of the idol This is their ignorance, that they were still under the influence of some superstitious notion, as if there were some virtue in the idol, or some virtue in a wicked and idolatrous consecration. Paul, however, does not speak of idolaters, who were entire strangers to pure religion, but of ignorant persons who had not been sufficiently instructed, to understand that an idol is nothing, and therefore that the consecration, which was gone through in name of the idol, is of no importance. Their idea, therefore, was this: “As an idol is something, the consecration which is gone through in its name is not altogether vain, and hence those meats are not pure, that have been once dedicated to idols.” Hence they thought, that, if they ate of them, they contracted some degree of pollution, and were, in a manner, partakers with the idol. This is the kind of offense that Paul reproves in the Corinthians — when we induce weak brethren, by our example, to venture upon anything against their conscience.

And their conscience God would have us try or attempt nothing but what we know for certain is agreeable to him. Whatever, therefore, is done with a doubting conscience, is, in consequence of doubts of that kind, faulty in the sight of God. And this is what he says, (Romans 14:23,) Whatsoever is not of faith is sin Hence the truth of the common saying, that “those build for hell, who build against their conscience.” For as the excellence of actions depends on the fear of God and integrity of conscience, so, on the other hand, there is no action, that is so good in appearance, as not to be polluted by a corrupt affection of the mind. For the man, who ventures upon anything in opposition to conscience, does thereby discover some contempt of God; for it is a token that we fear God, when we have respect to his will in all things. Hence you are not without contempt of God, if you so much as move a finger while uncertain, whether it may not be displeasing to him. As to meats, there is another thing to be considered, for they are not sanctified to us otherwise than by the word (1 Timothy 4:5.) If that word is wanting, there remains nothing but pollution — not that the creatures of God are polluted, but because man’s use of them is impure. In fine, as men’s hearts are purified by faith, so without faith there is nothing that is pure in the sight of God.
