1 Corinthians 11:27-29

King James Version

²⁷ Wherefore whosoever shall eat this bread, and drink this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord.

²⁸ But let a man examine himself, and so let him eat of that bread, and drink of that cup.

²⁹ For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord's body.
