1 Corinthians 11:17-28 Revised Standard Version (RSV)
Abuses at the Lord’s Supper
17 But 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, in the first place, when you assemble as a church, I hear that there are divisions among you; and I partly believe it, 19 for there must be factions among you in order that those who are genuine among you may be recognized. 20 When you meet together, it is not the Lord’s supper that you eat. 21 For in eating, each one goes ahead with his own meal, and one is hungry and another is drunk. 22 What! Do you not have houses to eat and drink in? Or do you despise the church of God and humiliate those who have nothing? What shall I say to you? Shall I commend you in this? No, I will not.
The Institution of the Lord’s Supper
23 For I received from the Lord what I also delivered to you, that the Lord Jesus on the night when he was betrayed took bread, 24 and when he had given thanks, he broke it, and said, “This is my body which is for[a] you. Do this in remembrance of me.” 25 In the same way also the cup, 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.
Partaking of the Supper Unworthily
27 Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of profaning the body and blood of the Lord. 28 Let a man examine himself, and so eat of the bread and drink of the cup.
