1 Corinthians 11:27LXX

25After the same manner also the cup, when he had supped, saying, This cup is the new testament in my blood: this do ye, as oft as ye drink , in remembrance of me.

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

27Wherefore whosoever shall eat this bread, and drink 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 bread, and drink of cup.

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