1 Corinthians 11:17-22, 28, 33-34

But in giving this instruction, I do not praise you, because you come together not for the better but for the worse. For, in the first place, when you come together as a church, I hear that divisions exist among you; and in part I believe it. For there must also be factions among you, so that those who are approved may become evident among you. Therefore when you meet together, it is not to eat the Lord’s Supper, for in your eating each one takes his own supper first; and one is hungry and another is drunk. What! Do you not have houses in which to eat and drink? 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 will not praise you.

But a man must examine himself, and in so doing he is to eat of the bread and drink of the cup.

So then, my brethren, when you come together to eat, wait for one another. If anyone is hungry, let him eat at home, so that you will not come together for judgment. The remaining matters I will arrange when I come.
