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:

(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.
