1 Corinthians 11:27-34

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. So then, my fellow believers, when you assemble as one to share a meal, show respect for one another and wait for all to be served. If you are that hungry, eat at home first, so that when you gather together you will not bring judgment upon yourself. When I come to you, I will answer the other questions you asked me in your letter.
