1 Corinthians 11:26-28

King James Version

²⁶ For as often as ye eat this bread, and drink this cup, ye do shew the Lord's death till he come.

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.
