10:29 Conscience, I say, not thine own, but of the other: {8} for why is my liberty judged of another [man's] conscience?
(8) A reason: for we must take heed that our liberty is not spoken of as evil, and that the benefit of God which we ought to use with thanksgiving is not changed into impiety. And this is through our fault, if we choose rather to offend the conscience of the weak, than to yield a little of our liberty in a matter of no importance, and so give occasion to the weak to judge in such sort of us, and of Christian liberty. And the apostle takes these things upon his own person, that the Corinthians may have so much the less occasion to oppose anything against him.
10:29 Conscience, I say, not thine own, but of the other. When one eats what he knows to be simply wholesome food, his own conscience is not offended, but that of another man.
Why is my liberty judged of another [man's] conscience? His liberty of conscience is not abridged by another man's want of knowledge.
10:29 Conscience I say, not thy own - I speak of his conscience, not thine. For why is my liberty judged by another's conscience - Another's conscience is not the standard of mine, nor is another's persuasion the measure of my liberty.
10:23-33 There were cases wherein Christians might eat what had been offered to idols, without sin. Such as when the flesh was sold in the market as common food, for the priest to whom it had been given. But a Christian must not merely consider what is lawful, but what is expedient, and to edify others. Christianity by no means forbids the common offices of kindness, or allows uncourteous behaviour to any, however they may differ from us in religious sentiments or practices. But this is not to be understood of religious festivals, partaking in idolatrous worship. According to this advice of the apostle, Christians should take care not to use their liberty to the hurt of others, or to their own reproach. In eating and drinking, and in all we do, we should aim at the glory of God, at pleasing and honouring him. This is the great end of all religion, and directs us where express rules are wanting. A holy, peaceable, and benevolent spirit, will disarm the greatest enemies.
