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

But in giving you this charge, I praise you not, that ye come together not for the better but for the worse. For first of all, when ye come together in the church, I hear that divisions exist among you; and I partly believe it. For there must be also heresies among you, that they which are approved may be made manifest among you. When therefore ye assemble yourselves together, it is not possible to eat the Lord's supper: for in your eating each one taketh before other his own supper; and one is hungry, and another is drunken. What? have ye not houses to eat and to drink in? or despise ye the church of God, and put them to shame that have not? What shall I say to you? shall I praise you in this? I praise you not.

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

Wherefore, my brethren, when ye come together to eat, wait one for another. If any man is hungry, let him eat at home; that your coming together be not unto judgement. And the rest will I set in order whensoever I come.
