1 Corinthians 10:16-20

Is the cup of blessing which we bless not a sharing in the blood of Christ? Is the bread which we break not a sharing in the body of Christ?

Since there is one loaf, we who are many are one body; for we all partake of the one loaf.

Look at the people of Israel; are those who eat the sacrifices not partners in the altar?

What do I mean then? That food sacrificed to idols is anything, or that an idol is anything?

No, but I say that things which the Gentiles sacrifice, they sacrifice to demons and not to God; and I do not want you to become partners with demons.
