1 Corinthians 11:25-26, 33

He did the same with the cup of wine after supper and said, “This cup seals the new covenant with my blood. Drink it—and whenever you drink this, do it to remember me.” Whenever you eat this bread and drink this cup, you are retelling the story, proclaiming our Lord’s death until he comes.

So then, my fellow believers, when you assemble as one to share a meal, show respect for one another and wait for all to be served.
