1 Corinthians 11:27-32

For this reason, whoever eats the bread or drinks the cup of the Lord in the wrong spirit will be guilty of dishonoring the body and blood of the Lord. So let each individual first evaluate his own attitude and only then eat the bread and drink the cup. For continually eating and drinking with a wrong spirit will bring judgment upon yourself by not recognizing the body. This insensitivity is why many of you are weak, chronically ill, and some even dying. If we have examined ourselves, we should not be judged. But when we are judged, it is the Lord’s training so that we will not be condemned along with the world.
