You cannot drink the cup of the Lord and also the cup of demons; you cannot be partakers in the Lord's table and in the table of demons.

In the same way also, he took the cup after supper, saying. "This cup is the new covenant in my blood; do this, whenever you drink it, in memory of me."

The cup of blessing which we bless, is it not a common participation in the blood of Christ? The bread which we break, is it not a common participation in the body of Christ?

For as often as you eat this bread and drink this cup, you are proclaiming your Lord's death until he come.

So he that eats the bread or drinks the cup of the Lord unworthy must answer for a sin against the body and blood of the Lord.

Let each man scrutinize himself, and thus let him eat of the bread and drink of the cup.
