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

But in giving you this command I don’t praise you, because you come together not for the better but for the worse. For first of all, when you come together in the assembly, I hear that divisions exist among you, and I partly believe it. For there also must be factions among you, that those who are approved may be revealed among you. When therefore you assemble yourselves together, it is not the Lord’s supper that you eat. For in your eating each one takes his own supper first. One is hungry, and another is drunken. What, don’t you have houses to eat and to drink in? Or do you despise God’s assembly and put them to shame who don’t have enough? What shall I tell you? Shall I praise you? In this I don’t praise you.

But let a man examine himself, and so let him eat of the bread and drink of the cup.

Therefore, my brothers, when you come together to eat, wait for one another. But if anyone is hungry, let him eat at home, lest your coming together be for judgment. The rest I will set in order whenever I come.
