You cannot drink the cup of the Lord, and the cup of demons: you cannot be partakers of the Lord's table, and of the table of demons.

After the same manner also he took the cup, after he had eaten, saying, This cup is the new testament in my blood: this do you, as often as you drink it, in remembrance of me.

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 as often as you eat this bread, and drink this cup, you do show the Lord's death till he comes.

Therefore whosoever shall eat this bread, and drink this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord.

But let a man examine himself, and so let him eat of that bread, and drink of that cup.
