The cup of blessing, which we bless, does it not mean a joint-participation in the blood of Christ? The loaf of bread which we break, does it not mean a joint-participation in the body of Christ?
Since there is one loaf, we who are many are one body; we, all of us, share in that one loaf.
Look at the Israelites--the nation and their ritual. Are not those who eat the sacrifices joint-partakers in the altar?
Do I mean that a thing sacrificed to an idol is what it claims to be, or that an idol is a real thing?
No, but that which the Gentiles sacrifice, they sacrifice to demons, not to God; and I would not have you have fellowship with one another through the demons.
You cannot drink the Lord's cup and the cup of demons: you cannot be joint-partakers both in the table of the Lord and in the table of demons.
Or are we actually arousing the Lord to jealousy. Are we stronger than He is?
Everything is allowable, but not everything is profitable. Everything is allowable, but everything does not build others up.
Let no one be for ever seeking his own good, but let each seek that of his fellow man.
Anything that is for sale in the meat market, eat, and ask no questions for conscience' sake;
for the earth is the Lord's, and all that it contains.
