1 Corinthians 10:15-24
I speak as to sensible men; judge for yourselves what I say. The cup of blessing which we bless, is it not a participation in the blood of Christ? The bread which we break, is it not a participation in the body of Christ? Because there is one bread, we who are many are one body, for we all partake of the one bread. Consider the people of Israel; are not those who eat the sacrifices partners in the altar?
What do I imply then? That food offered to idols is anything, or that an idol is anything? No, I imply that what pagans sacrifice they offer to demons and not to God. I do not want you to be partners with demons. You cannot drink the cup of the Lord and the cup of demons. You cannot partake of the table of the Lord and the table of demons. Shall we provoke the Lord to jealousy? Are we stronger than he?
"All things are lawful," but not all things are helpful. "All things are lawful," but not all things build up. Let no one seek his own good, but the good of his neighbor.
