1 Corinthians 11:17-28
New King James Version (NKJV)
Conduct at the Lord’s Supper
17 Now in giving these instructions I do not praise you, since you come together not for the better but for the worse.18 For first of all, when you come together as a church, I hear that there are divisions among you, and in part I believe it. 19 For there must also be factions among you, that those who are approved may be recognized among you.20 Therefore when you come together in one place, it is not to eat the Lord’s Supper. 21 For in eating, each one takes his own supper ahead of others; 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 shame those who have nothing? What shall I say to you? Shall I praise you in this? I do not praise you.
Institution of the Lord’s Supper
23 For I received from the Lord that which I also delivered to you: that the Lord Jesus on the same night in which He was betrayed took bread; 24 and when He had given thanks, He broke it and said, “Take, eat; this is My body which is broken for you; do this in remembrance of Me.” 25 In the same manner He also took the cup after supper, saying,“This cup is the new covenant in My blood. This do, as often as you drink it, in remembrance of Me.”
26 For as often as you eat this bread and drink this cup, you proclaim the Lord’s death till He comes.
27 Therefore whoever eats this bread or drinks this cup of the Lord in an unworthy manner will be guilty of the body and blood of the Lord. 28 But let a man examine himself, and so let him eat of the bread and drink of the cup.
