1 Corinthians 10:21 (KJV)

The 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?

For we being many are one bread, and one body: for we are all partakers of that one bread.

Behold Israel after the flesh: are not they which eat of the sacrifices partakers of the altar?

What say I then? that the idol is any thing, or that which is offered in sacrifice to idols is any thing?

But 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.

Do we provoke the Lord to jealousy? are we stronger than he?

All things are lawful for me, but all things are not expedient: all things are lawful for me, but all things edify not.

Let no man seek his own, but every man another's wealth.

Whatsoever is sold in the shambles, that eat, asking no question for conscience sake:

For the earth is the Lord's, and the fulness thereof.
