1 Corinthians 11:27-29

American Standard Version

²⁷ Wherefore whosoever shall eat the bread or drink the cup of the Lord in an unworthy manner, shall be guilty of the body and the blood of the Lord. ²⁸ But let a man prove himself, and so let him eat of the bread, and drink of the cup. ²⁹ For he that eateth and drinketh, eateth and drinketh judgment unto himself, if he ^[a]discern not the body.
