1 Corinthians 11:27-32

27For 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.

28A person should examine himself first, and in this way let him eat the bread and drink of the cup.

29For the one who eats and drinks without careful regard for the body eats and drinks judgment against himself.

30That is why many of you are weak and sick, and quite a few are dead.

31But if we examined ourselves, we would not be judged.

32But when we are judged by the Lord, we are disciplined so that we may not be condemned with the world.
