What did Paul tell the Corinthians to do about eating and drinking and the Lord's Supper?
Paul told the Corinthians to stop abusing the Lord's Supper: do their eating and drinking at home, and treat the Lord's house and Supper as a solemn occasion. He said each person should examine himself, not judge others, looking at his own heart and attitude before the Lord.
Les explains that the only purpose of the Lord's Supper is to remind yourself, not the person next to you or someone across the church, that Christ died, His blood was shed, and He arose from the dead. It is to be a solemn experience. The Corinthians were abusing this beautiful picture by indulgence with food and getting half drunk on too much wine. Paul upbraided them and said, 'Stop it. You do your eating and your drinking in your home, but when you come to the Lord's house for the Lord's Supper, it is a solemn occasion.' Whenever they did this, they showed the Lord's death until He comes, and the Lord's table will not stop until the Lord returns. Paul also describes the attitude in verse 27: whoever eats this bread and drinks this cup unworthily is guilty of the body and blood of the Lord, so let a man examine himself. Les says that is the secret to behavior at communion: you do not examine the next person or judge the person across the church; you look at your own heart and attitude and ask, 'Am I right with the Lord?'
