You cannot drink the cup of the Lord and the cup of demons. You cannot take part in the table of the Lord and the table of demons.

In the same way, he also took the cup after supper, saying, "This cup is the new covenant in my blood. Do this, every time you drink it, in remembrance of me."

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

For every time you eat this bread and drink the cup, you proclaim the Lord's death until he comes.

For this reason, whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of the body and blood of the Lord.

A person should examine himself first, and in this way let him eat the bread and drink of the cup.
