1 Corinthians 11:17-26 New Revised Standard Version (NRSV)
Abuses at the Lord’s Supper
17 Now in the following instructions I do not commend you, because when you come together it is not for the better but for the worse. 18 For, to begin with, when you come together as a church, I hear that there are divisions among you; and to some extent I believe it. 19 Indeed, there have to be factions among you, for only so will it become clear who among you are genuine. 20 When you come together, it is not really to eat the Lord’s supper. 21 For when the time comes to eat, each of you goes ahead with your own supper, and one goes hungry and another becomes drunk. 22 What! Do you not have homes to eat and drink in? Or do you show contempt for the church of God and humiliate those who have nothing? What should I say to you? Should I commend you? In this matter I do not commend you!
The Institution of the Lord’s Supper
23 For I received from the Lord what I also handed on to you, that the Lord Jesus on the night when he was betrayed took a loaf of bread, 24 and when he had given thanks, he broke it and said, “This is my body that is for[a] you. Do this in remembrance of me.” 25 In the same way he took the cup also, after supper, saying, “This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me.” 26 For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until he comes.
