1 Corinthians 11

17 When Christians meet together, they are supposed to encourage and help one another. In the Corinthian church, the opposite was happening. People were leaving worse off than when they came.
18 Divisiveness is detrimental to a church. It is symptomatic of pride among the members.
19 The only division that should be recognized is between those who know Jesus and those who do not.
20 At their meetings, they claimed to eat the Lord's supper, but Paul is about to explain that their attitude and actions defeated the purpose of it. The Lord's supper is more than just eating bread and drinking wine. It is supposed to be a point of unity where we remember in humility what Jesus had to do for each one of us.
21 Some of the problems would occur at the "love feast," or Agape, that was held before the Lord's supper. The people did not wait for others, nor did they share their food with those who had nothing to bring. It was made more shameful because their attitude encouraged drunkards at their meetings.
22 If those who had food were really so hungry that they could not wait for others or share, then they should eat some at home before arriving. Those who had food should recognize that there are those who legitimately can not afford to bring food for themselves or others. This should be a point of ministry for them. It was outlandish that one would gorge himself while someone across the table starved.
23 This statement implies that the resurrected Jesus told Paul about this event. He did not first hear about it from the disciples who were there.
24 When we eat the bread, we are supposed to remember that Jesus was broken for us. While this need not always be a solemn ceremony, it should be done with reverence.
25 It appears that Jesus broke the bread before the Passover meal and then shared the cup after the meal.

When we drink the cup, we are to remember that Jesus gave His life for us. This is symbolic of the new covenant sealed with His blood rather than the old one which was sealed with the blood of lambs.

The Greek word for "covenant" used in this verse does not refer to an agreement between equals. The terms of salvation through Jesus' blood is set out by God, and each individual must either accept or reject them.

27 Those who eat the Lord's supper without repentance and respect make a mockery of what it stands for.
28 When we approach the Lord's supper we must look at our lives and repent (or turn away) from our sins.
29 Those who do not examine their lives will be judged for their hypocrisy. They claimed life through the death of Jesus, but never took the necessary steps of faith to repent.
30 Similar to the fashion, in which God would strike down faithless people by plagues, the Corinthian church had many who were sick and dying (spiritually and physically). The result was a less effective witness to the community.

This might also be said of the Church in some parts of the world today. In the United States, for instance, church membership has dropped dramatically in the last few decades. When asked, the common person would say that Christians are greedy hypocrites rather than loving people who know God. This reputation would not prevail if we would take Jesus seriously and learn to repent, trust, and love.

31 God has given us reasoning, a conscious, and the Holy Spirit. These are sufficient to see and repent of the sin found in our lives. As a Christian community, we should help each other see and deal with sins. We do not want to be put to shame on Judgement Day when all things are revealed.
32 God may judge some of our sins while we are still alive. The purpose of such punishment is to get us to repent and to restore our relationship with Him.
33 The purpose of the Lord's supper is to celebrate our shared salvation through Jesus. We should therefore eat it together.
34 If someone can not show restraint, he should take preventative measures so that he will not displease God by his selfish actions.
