11:17-22 The apostle rebukes the disorders in their partaking of the Lord's supper. The ordinances of Christ, if they do not make us better, will be apt to make us worse. If the use of them does not mend, it will harden. Upon coming together, they fell into divisions, schisms. Christians may separate from each other's communion, yet be charitable one towards another; they may continue in the same communion, yet be uncharitable. This last is schism, rather than the former. There is a careless and irregular eating of the Lord's supper, which adds to guilt. Many rich Corinthians seem to have acted very wrong at the Lord's table, or at the love-feasts, which took place at the same time as the supper. The rich despised the poor, and ate and drank up the provisions they brought, before the poor were allowed to partake; thus some wanted, while others had more than enough. What should have been a bond of mutual love and affection, was made an instrument of discord and disunion. We should be careful that nothing in our behaviour at the Lord's table, appears to make light of that sacred institution. The Lord's supper is not now made an occasion for gluttony or revelling, but is it not often made the support of self-righteous pride, or a cloak for hypocrisy? Let us never rest in the outward forms of worship; but look to our hearts.
21. one taketh before other—the rich "before" the poor, who had no supper of their own. Instead of "tarrying for one another" (1Co 11:33); hence the precept (1Co 12:21, 25).
his own supper—"His own" belly is his God (Php 3:19); "the Lord's Supper," the spiritual feast, never enters his thoughts.
drunken—The one has more than is good for him, the other less [Bengel].
