1 Corinthians 11:26-29

Noyes(i) 26 For as often as ye eat this bread, and drink the cup, ye show forth the Lords death, till he come. 27 So that whoever eateth the bread or drinketh the cup of the Lord in an unworthy manner will be guilty with respect to the body and the blood of the Lord. 28 But let a man examine himself, and thus let him eat of the bread, and drink of the cup; 29 for he that eateth and drinketh eateth and drinketh judgment to himself, if he do not discern the body.
