What did the Lord reveal to Paul about the institution of the Lord's Supper?

Les explains that by the time Paul writes the I Corinthians letter, the church of Corinth had been operating long enough to build these excesses and was getting all these kooky ideas coming in. This was not what Paul taught them at the beginning; it had become an evolutionary thing, moving from one position to another and getting worse instead of better. So Paul says this isn't how he taught them to practice the Lord's Supper. Men can connive and come up with crazy ideas that lead to excesses, and that is exactly what happened at Corinth. Apparently when they got ready for the Lord's Table, they realized a little cup or swallow of wine and one little piece of unleavened bread could not satisfy a whole day's energy, so they decided to bring food and have a real supper. But it led to excesses, so Paul had to bring criticism. He tells them exactly how it all came about. This is what the Lord revealed to him: the Lord Jesus, the same night in which He was betrayed, took bread, and when He had given thanks, He broke it and said, 'Take, eat; this is My body which is broken for you; this do ye.'
