19 What say I then? that a thing sacrificed to idols is anything, or that an idol is anything? 20 But [I say], that the things which the Gentiles sacrifice, they sacrifice to demons, and not to God: and I would not that ye should have communion with demons. 21 Ye cannot drink the cup of the Lord, and the cup of demons: ye cannot partake of the table of the Lord, and of the table of demons. 22 Or do we provoke the Lord to jealousy? are we stronger than he?

Do All to the Glory of God

23 All things are lawful; but not all things are expedient. All things are lawful; but not all things edify. 24 Let no man seek his own, but [each] his neighbor's [good]. 25 Whatsoever is sold in the shambles, eat, asking no question for conscience' sake, 26 for the earth is the Lord's, and the fulness thereof. 27 If one of them that believe not biddeth you [to a feast], and ye are disposed to go; whatsoever is set before you, eat, asking no question for conscience' sake. 28 But if any man say unto you, This hath been offered in sacrifice, eat not, for his sake that showed it, and for conscience sake: 29 conscience, I say, not thine own, but the other's; for why is my liberty judged by another conscience? 30 If I partake with thankfulness, why am I evil spoken of for that for which I give thanks? 31 Whether therefore ye eat, or drink, or whatsoever ye do, do all to the glory of God. 32 Give no occasions of stumbling, either to Jews, or to Greeks, or to the church of God: 33 even as I also please all men in all things, not seeking mine own profit, but the [profit] of the many, that they may be saved.

Commentary on 1 Corinthians 10:15-22

(Read 1 Corinthians 10:15-22)

Did not the joining in the Lord's supper show a profession of faith in Christ crucified, and of adoring gratitude to him for his salvation ? Christians, by this ordinance, and the faith therein professed, were united as the grains of wheat in one loaf of bread, or as the members in the human body, seeing they were all united to Christ, and had fellowship with him and one another. This is confirmed from the Jewish worship and customs in sacrifice. The apostle applies this to feasting with idolaters. Eating food as part of a heathen sacrifice, was worshipping the idol to whom it was made, and having fellowship or communion with it; just as he who eats the Lord's supper, is accounted to partake in the Christian sacrifice, or as they who ate the Jewish sacrifices partook of what was offered on their altar. It was denying Christianity; for communion with Christ, and communion with devils, could never be had at once. If Christians venture into places, and join in sacrifices to the lust of the flesh, the lust of the eye, and the pride of life, they will provoke God.

Commentary on 1 Corinthians 10:23-33

(Read 1 Corinthians 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.
