Idol Feasts and the Lord’s Supper
14 Therefore, my dear friends, flee from idolatry. 15I speak to sensible people; judge for yourselves what I say. 16Is not the cup of thanksgiving for which we give thanks a participation in the blood of Christ? And is not the bread that we break a participation in the body of Christ? 17Because there is one loaf, we, who are many, are one body, for we all partake of the one loaf.
18 Consider the people of Israel: Do not those who eat the sacrifices participate in the altar? 19Do I mean then that a sacrifice offered to an idol is anything, or that an idol is anything? 20No, but the sacrifices of pagans are offered to demons, not to God, and I do not want you to be participants with demons. 21You cannot drink the cup of the Lord and the cup of demons too; you cannot have a part in both the Lord’s table and the table of demons. 22Are we trying to arouse the Lord’s jealousy? Are we stronger than he?
