1 Corinthians 11:27-29

Verse

27 Therefore, whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of sinning against the body and blood of the Lord. 28 Each one must examine himself before he eats of the bread and drinks of the cup. 29 For anyone who eats and drinks without recognizing the body eats and drinks judgment on himself.
