1 Corinthians 11:29-31

Living Bible

²⁹ For if he eats the bread and drinks from the cup unworthily, not thinking about the body of Christ and what it means, he is eating and drinking God’s judgment upon himself; for he is trifling with the death of Christ. ³⁰ That is why many of you are weak and sick, and some have even died.

³¹ But if you carefully examine yourselves before eating you will not need to be judged and punished.
