1 Corinthians 11
26 Ref For as often as you eat this bread and drink this cup, you proclaim the Lord's death until he comes.
27 Ref Therefore whoever eats this bread or drinks the Lord's cup in a manner unworthy of the Lord will be guilty of the body and the blood of the Lord.
28 Ref But let a man examine himself, and so let him eat of the bread, and drink of the cup.
29 Ref For he who eats and drinks in an unworthy manner eats and drinks judgment to himself, if he doesn't discern the Lord's body.
