1 Corinthians 11:20-22
20-22And then I find that you bring your divisions to worship—you come together, and instead of eating the Lord's Supper, you bring in a lot of food from the outside and make pigs of yourselves. Some are left out, and go home hungry. Others have to be carried out, too drunk to walk. I can't believe it! Don't you have your own homes to eat and drink in? Why would you stoop to desecrating God's church? Why would you actually shame God's poor? I never would have believed you would stoop to this. And I'm not going to stand by and say nothing.
23-26Let me go over with you again exactly what goes on in the Lord's Supper and why it is so centrally important. I received my instructions from the Master himself and passed them on to you. The Master, Jesus, on the night of his betrayal, took bread. Having given thanks, he broke it and said,
This is my body, broken for you.
Do this to remember me.
After supper, he did the same thing with the cup:
This cup is my blood, my new covenant with you.
Each time you drink this cup, remember me.
What you must solemnly realize is that every time you eat this bread and every time you drink this cup, you reenact in your words and actions the death of the Master. You will be drawn back to this meal again and again until the Master returns. You must never let familiarity breed contempt.
