1 Corinthians 11:23-34

For I received from the Lord the teaching that I passed on to you: that the Lord Jesus, on the night he was betrayed, took a piece of bread, gave thanks to God, broke it, and said, “This is my body, which is for you. Do this in memory of me.” In the same way, after the supper he took the cup and said, “This cup is God's new covenant, sealed with my blood. Whenever you drink it, do so in memory of me.” This means that every time you eat this bread and drink from this cup you proclaim the Lord's death until he comes. It follows that if one of you eats the Lord's bread or drinks from his cup in a way that dishonors him, you are guilty of sin against the Lord's body and blood. So then, you should each examine yourself first, and then eat the bread and drink from the cup. For if you do not recognize the meaning of the Lord's body when you eat the bread and drink from the cup, you bring judgment on yourself as you eat and drink. That is why many of you are sick and weak, and several have died. If we would examine ourselves first, we would not come under God's judgment. But we are judged and punished by the Lord, so that we shall not be condemned together with the world. So then, my friends, when you gather together to eat the Lord's Supper, wait for one another. And if any of you are hungry, you should eat at home, so that you will not come under God's judgment as you meet together. As for the other matters, I will settle them when I come.
