Immediately preceding Paul’s instructions to the Corinthian church about communion, he admonishes them about their selfishness.
When you come together, it is not the Lord’s supper that you eat. For in eating, each one goes ahead with his own meal. One goes hungry, another gets drunk. What! Do you not have houses to eat and drink in? Or do you despise the church of God and humiliate those who have nothing? What shall I say to you? Shall I commend you in this? No, I will not. (1 Corinthians 11:20–22, ESV)
The congregation certainly called what they were doing the Lord’s table. So why does Paul say “it is not the Lord’s supper that you eat”? Because self-absorbed, self-serving does not belong at His table. Taking, hoarding, and mocking don’t belong at the Lord’s table, the Lord who gave and gives, the Lord who shares Himself and His resources extravagantly, the Lord who gives and shares with those who are not at His level, the kind of people that a selfish god would mock.
Eating with an attitude of superiority toward others, brought in from before the service or that arises during our time together, is one way of eating and drinking in an unworthy manner. That sort of selfish participation makes one guilty of profaning the body and blood of the Lord.
The Word became flesh for us. He gave His body for us, represented by the bread. He bled for us, represented by the cup. Let us thank Him, and let us honor His sacrifice as we sacrifice for each other, as we wait for each other, and think more highly of our neighbor’s eating than our own.
