1 Corinthians 11:26-28

Verse

26 For as often as you eat this bread and drink this cup, you proclaim the Lord’s death until He comes. 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.
