1 Corinthians 11:21

"For in your eating, each one taketh before other his own supper," saith he, "and one is hungry, and another is drunken." Perceivest thou how he intimates that they were disgracing themselves rather? For that which is the Lord's, they make a private matter: so that themselves are the first to suffer indignity, depriving their own table of its greatest prerogative. How and in what manner? Because the Lord's Supper, i.e., the Master's, ought to be common. For the property of the master belongs not to this servant without belonging to that, but in common to all. So that by "the Lord's" Supper he expresses this, the "community" of the feast. As if he had said, "If it be thy master's, as assuredly it is, thou oughtest not to withdraw it as private, but as belonging to thy Lord and Master to set it in common before all. For this is the meaning of, 'the Lord's.' But now thou dost not suffer it to be the Lord's, not suffering it to be common but feasting by thyself." Wherefore also he goes on to say, "For each one taketh before other his own supper." And he said not, "cutteth off," but "taketh before," tacitly censuring them both for greediness and for precipitancy. This at least the sequel also shows. For having said this, he added again, "and one is hungry, and another is drunken," each of which showed a want of moderation, both the craving and the excess. See also a second fault again whereby those same persons are injured: the first, that they dishonor their supper: the second, that they are greedy and drunken; and what is yet worse, even when the poor are hungry. For what was intended to be set before all in common, that these men fed on alone, and proceeded both to surfeiting and to drunkenness. […]

And among those who have, they, who eat shamelessly and are insatiable, shame themselves. And both act badly; the one by paining those who have not, the other by exposing their own greed in the presence of those who have.

You have turned this Lord's Supper into your own private one. For as long as it was common, it was also called the Lord's Supper; for the Master's goods are common to all servants. But since each one hastens to eat his own supper, not …

Then when he says, For each one, he mentions the fault: first, insofar as they sinned against God; secondly, insofar as they sinned against their neighbor (v. 21b). He says, therefore, first: The reason I say that it is not lawful for you to eat …

For in eating what ye call the Lord's supper, instead of all partaking of one bread, each person brings his own supper, and eats it without staying for the rest. And hereby the poor, who cannot provide for themselves, have nothing; while the rich eat and drink to the full just as the heathens use to do at the feasts on their sacrifices.
