27 Therefore whoever may eat this bread or drink the cup of the Lord unworthily of the Lord, will be guilty of the body and the blood of the Lord.
28 But let a man examine himself, and let him so eat of the bread, and drink of the cup.
29 For he who eats and drinks unworthily, eats and drinks condemnation to himself, not discerning the body of the Lord.
30 Because of this many are weak and sickly among you, and a considerable sleep.
