“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” (v20-21). Jesus had given His followers the sacred tradition of communion - eating and drinking together to remember His death, resurrection, and return (v23-26). However, the Corinthians weren’t sharing their food and drink in a reverent way, but instead indulging themselves, ignoring those with less to eat, and even getting drunk. Their behavior needed self-correction (v27-31) to avoid real judgment.
“I hear that there are divisions among you …” (v18). Divisions and in-fighting within the Body of Christ undermine the radical unity we share because of Jesus’ sacrifice for us.
