1 Corinthians 11:26-30 Amplified Bible (AMP)

26. For every time you eat this bread and drink this cup, you are representing and signifying and proclaiming the fact of the Lord's death until He comes [again].

27. So then whoever eats the bread or drinks the cup of the Lord in a way that is unworthy [of Him] will be guilty of [profaning and sinning against] the body and blood of the Lord.

28. Let a man [thoroughly] examine himself, and [only when he has done] so should he eat of the bread and drink of the cup.

29. For anyone who eats and drinks without discriminating and recognizing with due appreciation that [it is Christ's] body, eats and drinks a sentence (a verdict of judgment) upon himself.

30. That [careless and unworthy participation] is the reason many of you are weak and sickly, and quite enough of you have fallen into the sleep of death.
