15I speak as to wise men; judge ye what I say. 16The cup of blessing which we bless, is it not the communion of the blood of Christ? The bread which we break, is it not the communion of the body of Christ? 17For we being many are one bread, and one body: for we are all partakers of that one bread. 18Behold Israel after the flesh: are not they which eat of the sacrifices partakers of the altar?19What say I then? that the idol is any thing, or that which is offered in sacrifice to idols is any thing? 20But I say, that the things which the Gentiles sacrifice, they sacrifice to devils, and not to God: and I would not that ye should have fellowship with devils. 21Ye cannot drink the cup of the Lord, and the cup of devils: ye cannot be partakers of the Lord's table, and of the table of devils.
