1 Corinthians 11:27-32

27Therefore whoever shall eat this bread, and drink this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord. 28But let a man examine himself, and so let him eat of that bread, and drink of that cup. 29For he that eateth and drinketh unworthily, eateth and drinketh judgment to himself, not discerning the Lord’s body.1 30For this cause many are weak and sickly among you, and many sleep. 31For if we would judge ourselves, we should not be judged. 32But when we are judged, we are chastened by the Lord, that we should not be condemned with the world.
