John Gill Commentary 1 Corinthians 11:33

"Wherefore, my brethren, when ye come together to eat, wait one for another." — 1 Corinthians 11:33 (ASV)

Wherefore, my brethren
Though he had said some very awful and awakening things to bring them to themselves, to reclaim them, and rectify disorders among them; yet he hoped well of them in general, and softens the severe things he had said, by calling them "brethren"; and hereby prepares them to attend to, and receive the more kindly, what he had further to say:

when you come together to eat ;
that is, when you come to the place of public worship at the usual stated time, in order to eat the Lord's supper, tarry one for another; do not begin to celebrate the ordinance until the church is met together in general, or at least till as many are got together as may be expected will come; for a church is not obliged to tarry for every individual person; nor can it be thought that every member can attend, there being various providences which may detain them: the apostle's view is to promote unity, Christian respect, and brotherly love in the ordinance; that they would sit down and join together, according to the rule of Christ, without respect to persons, or going into parties and divisions.
