1 Corinthians 11:27-32

27Therefore, whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of sinning against the1 body and blood of the Lord. 28Each one must examine himself before he eats of the bread and drinks of the cup. 29For anyone who eats and drinks without recognizing the body2 eats and drinks judgment on himself. 30That is why many among you are weak and sick, and a number of you have fallen asleep.

31Now if we judged ourselves properly, we would not come under judgment. 32But when we are judged by the Lord, we are being disciplined so that we will not be condemned with the world.
