Meaning in one sentence

Paul says the cup and bread are a sharing in Christ's blood and body. This real communion excludes any fellowship with idols. Full meaning explained.

I Corinthians New Testament Greek

Context

Paul is writing to a church that prided itself on wisdom but struggled with compromise. In chapter 10, he turns to the problem of participating in feasts held in pagan temples. The Corinthians thought they could eat idol-food without consequence, since the idols were nothing. Paul argues that acts of worship create real fellowship, not with the lifeless idol, but with the spiritual powers behind it. To make his point, he holds up the Lord’s Supper. The phrase “cup of blessing” would echo for Jewish readers the Passover cup over which thanks were given. By taking that cup and breaking that bread, Paul says, believers share in Christ’s own sacrifice. That union is too deep to share with anything else.

Key Words

Two Greek words carry the weight here. The first is koinonia, translated as “communion” or “participation.” It does not mean a casual get-together. It describes a shared possession, a partnership in which each person has a stake in the same reality. When Paul asks whether the cup is koinonia in Christ’s blood, he is saying that what we receive is not a symbol we hold at arm’s length. We actually share in the benefits of his sacrifice. The second word group is eulogia (blessing) and eulogeo (we bless). This is not the minister blessing the cup alone. The whole congregation joins in pronouncing praise to God over the cup, setting it apart for this holy purpose. Together, these words teach that the Supper is an act of the whole church, drawing believers into a real, ongoing union with the crucified and risen Christ.

How Christians Read This Verse

Christians have always seen in this verse a profound claim about the Lord’s Supper, though they describe that claim differently. The Catholic and Orthodox traditions teach that the bread and wine truly become Christ’s body and blood, so that the communicant receives Christ himself. Many Reformed and Evangelical Christians speak of a spiritual presence: Christ is really present by faith, nourishing the soul. Methodists such as Wesley described the Supper as “the means of our partaking of those invaluable benefits” purchased by Christ’s death. What all these traditions share is the conviction that this is no mere memorial. It is a genuine communion with Christ, and that union has consequences, which is exactly Paul’s point in the verses that follow.

A common misunderstanding

Some readers hear “communion” and think Paul only means fellowship with each other, a shared meal that builds unity. In fact, the Greek koinonia is aimed first at Christ. The cup is a participation in his blood; the bread is a participation in his body. Belonging to each other comes from first belonging to him. Paul’s argument about idolatry only makes sense if the Supper binds us to Christ in a way that cannot be shared with any other spiritual allegiance.

Living This Out

This Sunday, if you take the bread and the cup, let them ask you a question: What else are you sharing your heart with? The Supper is not just a quiet moment for personal reflection. It is an act that aligns you with Christ, body, blood, and all the cost of his love. If you are holding onto a loyalty that competes with him, the Supper calls it out. You do not have to leave that competition behind perfectly before you come. But come honestly, and let the communion itself pull you back to the One who gave everything for you. That is what it is for.

Main takeaway: The Lord’s Supper is a real sharing in Christ’s sacrifice that unites us to him and calls for exclusive loyalty.

For Families

For ages 5, 8

The cup and bread at church are special. They remind us that Jesus died for us. When we take them, we are saying we belong to him.

For ages 9, 12

Paul says the cup is a “participation” in Jesus’ blood. That means when you take communion, you are really sharing in what Jesus did for you. It’s like a promise that you are his, so you shouldn’t follow other gods or let other things be more important than him.

Questions People Ask

What is the “cup of blessing” in this verse?

The phrase comes from Jewish practice. At the Passover meal, a cup of wine was lifted while blessing God for his deliverance. Paul uses that familiar term for the cup of the Lord’s Supper, the wine over which the church gives thanks and which sets it apart as a holy sign of Christ’s blood.

Does “communion of the blood of Christ” mean the wine actually becomes his blood?

Christians have answered this differently for centuries. Catholic and Orthodox believers hold that the bread and wine become Christ’s real body and blood. Many Protestant traditions speak of a spiritual presence, Christ is truly received by faith, though the elements remain bread and wine. Both sides agree that the Supper is more than a symbol; it is a genuine participation in Christ.

How does this verse forbid eating food sacrificed to idols?

Paul’s logic is simple: if sharing the cup and bread joins you to Christ, then sharing food at an idol’s feast joins you to the demonic powers behind that idol. You cannot be in real fellowship with Christ and with anything that opposes him at the same time.

Is “communion” here only about believers sharing with each other?

No. The Greek word koinonia means participation in a common reality. The primary connection is with Christ himself, his blood and body. Fellowship with other believers is a result (verse 17 says we are one body because we share the one bread), but the heart of the word is sharing in Christ.

Why does Paul mention the cup before the bread?

This order is unusual; Matthew, Mark, and Luke all describe Jesus blessing the bread first. Some commentators think Paul leads with the cup because he intends to contrast it with the “cup of demons” in verse 21, or because drinking was especially prominent in the idol feasts he is warning against.
