Contemporary Worship || Don't Mix Altars

The wedding reception image makes the point plain: the host sets the table, chooses the meal, and determines the guest list. The Lord’s Supper is not the church’s table. The Lord’s Supper is Christ’s table. Christ is the host, and even more amazingly than that, Christ is also the meal.

Paul begins abruptly in 1 Corinthians 10: “Therefore, my beloved, flee from idolatry.” Paul does not say manage idolatry or avoid it if possible. Paul says run, because idolatry is never spiritually neutral. Corinth’s temples, civic meals, trade gatherings, and marketplace meat made false worship feel ordinary, but Paul says something darker stands behind false worship. Every altar has communion, and every act of worship joins a person to someone.

Paul’s warning is sharp: no one can drink the cup of the Lord and the cup of demons. No one can partake of the table of the Lord and the table of demons. Idolatry has changed clothes, but it has not disappeared. Money, success, politics, entertainment, approval, sports, careers, and even family can become altars when the heart fears, loves, or trusts them above God. The sinful nature wants both Christ and idols, forgiveness without repentance, communion without faithfulness.

Paul’s word “participation” means koinonia, communion, fellowship, and sharing. The cup is a participation in the blood of Christ, and the bread is a participation in the body of Christ. The Lord’s Supper is not pretending, not remembering only, and not merely a symbol. Luther held to Christ’s own words: “This is my body.” Faith does not explain Christ’s words away. Faith receives Christ’s words.

John 6 gives the same depth to the feast. Jesus calls himself the living bread from heaven and says that his flesh is given for the life of the world. Jesus does not merely host the feast at the altar. Jesus becomes the feast. The shepherd becomes the lamb, the priest becomes the sacrifice, and the creator becomes food for his creatures.

The manna in Exodus sustained Israel for earthly life, but those who ate it still died. Christ’s body conquered death. Manna carried Israel toward Canaan, but Christ sustains his church toward the new creation. Christ’s body needs nothing added to it. His sacrifice is finished, his blood is shed, and his table gives everything to empty-handed guests.

The Lord’s table is holy, not casual or common. The church has no authority to change Christ’s guest list or redefine Christ’s meal. Yet Christ prepares this table for repentant sinners, weak Christians, weary saints, and those who know they need mercy. At his table, the same Jesus who died and rose gives his body and blood for the forgiveness of sins.

Key Takeaways

• 1. Christ hosts his own table The Lord’s Supper belongs to Christ before it belongs to any congregation, custom, or preference. The host determines the meal, and Christ has not left the church free to rearrange what he has prepared. The deepest comfort is that the guest does not bring the gift to the table. Christ provides himself. [35:43]
• 2. Idolatry is never spiritually neutral Paul’s command to flee idolatry treats false worship as a real danger, not as harmless background noise. An idol may not be carved from stone, but the heart can still build altars out of control, approval, pleasure, or success. The danger is not only loving the wrong thing, but trying to keep Christ while still communing with a rival table. [38:25]
• 3. Faith receives Christ’s plain words Christ says, “This is my body,” and faith does not improve those words by softening them. The mystery of the Supper is not solved by reducing it to a reminder, because Christ gives what he promises. The believer does not master the sacrament by explanation, but receives the body and blood because Christ is trustworthy. [44:05]
• 4. Christ’s body needs nothing added The cross does not invite human completion, extra merit, or repeated sacrifice. “It is finished” means the meal at the altar is pure gift, not a transaction. The empty-handed sinner receives everything from the crucified and risen Christ, because the host has already supplied the feast. [48:17]
• 5. The feast strengthens weary saints Christ’s table is not for those pretending to be strong, spotless, or self-sufficient. Christ gives his body and blood to repentant sinners who know their need for mercy. The same Jesus who died, rose, and reigns now feeds his people with forgiveness, faith, and a foretaste of the wedding feast to come. [51:11]

1. What does Paul mean when he says, “You cannot drink the cup of the Lord and the cup of demons” (1 Corinthians 10:21)? How does this contrast two types of “tables”?
2. In John 6:51, Jesus says, “The bread that I will give for the life of the world is my flesh.” How does this connect to the sermon’s emphasis on Christ being both the host and the meal?
3. How does the manna in Exodus 16 differ from the “living bread” Jesus describes in John 6? [46:09]
4. What does the word koinonia (“participation”) imply about the relationship between believers and Christ in the Lord’s Supper? [41:22]

1. Why does Paul treat idolatry as a danger requiring immediate action (“flee”) rather than mere caution? How might this apply to modern forms of idolatry?
2. The sermon states, “Every altar has communion, and every act of worship joins a person to someone.” What does this reveal about the spiritual reality behind daily choices and priorities? [38:25]
3. Jesus says, “Unless you eat my flesh and drink my blood, you have no life in you” (John 6:53). Why would this language have been startling to His audience, and how does it challenge common misunderstandings of communion?
4. How does the finished work of Christ (“It is finished”) shape the way believers approach the Lord’s Supper? [48:17]

1. What modern “altars” (e.g., success, approval, control) compete for your heart’s worship? How might these subtly claim your fear, love, or trust more than God? [39:31]
2. The Lord’s Supper is described as a gift for “weary saints” and “repentant sinners.” How can this truth reshape feelings of unworthiness or shame when approaching communion? [51:11]
3. In what areas of life do you struggle to live with “undivided loyalty” to Christ, and how might this affect your participation in His table? [40:43]
4. The sermon warns against treating communion as “casual or common.” What practical steps could help you prepare your heart to receive this gift with reverence and gratitude? [49:08]
5. How does recognizing Christ as both host and meal in the Lord’s Supper change your understanding of what you receive in this sacrament? [35:43]
6. The manna in Exodus was daily bread, but Christ’s body offers eternal life. How might this truth encourage someone feeling spiritually weary or stuck in repetitive struggles? [47:20]
7. Paul says idolatry often hides in ordinary things (meals, work, relationships). What habits or rhythms could help you regularly “flee” subtle idolatry in daily life? [36:10]
