1 Corinthians 11

[23] For I have received of the Lord that which also I delivered unto you, That the Lord Jesus the same night in which he was betrayed took bread:
[24] And when he had given thanks, he brake it, and said, Take, eat: this is my body, which is broken for you: this do in remembrance of me.
[25] After the same manner also he took the cup, when he had supped, saying, This cup is the new testament in my blood: this do ye, as oft as ye drink it, in remembrance of me.
[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.
[29] For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord's body.
[30] For this cause many are weak and sickly among you, and many sleep.
[31] For if we would judge ourselves, we should not be judged.
[32] But when we are judged, we are chastened of the Lord, that we should not be condemned with the world.
