A Complete Bible Study on Communion

Genesis 14 is not a communion service, and we should not force it to be one. It is a real historical moment after Abram rescues Lot and defeats a coalition of kings. As Abram returns, two figures come out to meet him: the king of Sodom and Melchizedek king of Salem. The contrast is important. Sodom will try to make a bargain. Melchizedek brings blessing.

The bread and wine are not the center of the passage. The blessing is. Even more, God is the center. Melchizedek blesses Abram, but he also blesses God Most High, giving God the credit for Abram’s victory. Abram receives this priestly blessing before refusing the corrupt offer of Sodom. The flow is not accidental. Abram is strengthened to honor God rather than be enriched by a wicked king.

Melchizedek is called king of Salem and priest of God Most High. Later in Israel’s law, kings and priests are separated by tribe and office. Here, before Moses, this figure appears as both king and priest. Hebrews later uses Melchizedek to display the superiority and permanence of Christ’s priesthood.

Unforsaken understands Melchizedek as a Christophany. Hebrews says he is made like the Son of God, and the whole argument points beyond ordinary human priesthood to Christ’s eternal priesthood. Still, Genesis 14 should be handled with restraint. The scene gives bread and wine in a priestly context of blessing and worship, but Jesus Himself institutes the Lord’s Supper later, during Passover, on the night before the cross.

The Lord’s Supper comes from Jesus, not from later church tradition. He gave it in a Passover setting. Passover already carried the memory of deliverance from Egypt through the blood of a lamb. Jesus takes that memorial setting and shows its fulfillment in His own coming death.

Jesus ties the bread to His body given and the cup to His blood shed. This is not vague religious symbolism. It is cross-centered. His death is covenant-making blood. His body is truly given. His blood is truly shed. Communion must never become so symbolic that the reality behind the symbol is softened. The bread and cup point to real suffering, real blood, real death, and real salvation.

At the same time, Jesus gives the action as remembrance. He does not command His disciples to create His body, repeat His death, or offer Him again. He commands them to remember Him. The elements direct believers to the once-for-all sacrifice that was about to be accomplished on the cross.

Remembrance in Scripture is more than mental recall. It brings the truth back to the center so it shapes worship, faith, and obedience. When the church receives the bread and the cup, we are not trying to make Christ present by ritual power. We are deliberately placing His finished work before the congregation again.

Paul says he received instruction concerning the Lord’s Supper and delivered it to the church. He repeats the words of institution and then explains what the church is doing when it partakes.

Communion is proclamation. The church is preaching without a long speech: Christ died. His death was for sinners. His blood is the blood of the new covenant. His sacrifice is enough. He is coming again. The Lord’s Supper looks backward to the cross and forward to His return. It also looks around at the gathered church and says that believers share one Savior and one hope.

That is why communion belongs to believers. It is not a tool to create saving faith in an unbeliever. It is an ordinance for those who have already come to Christ by faith. A person does not become forgiven by eating bread or drinking from a cup. Forgiveness is received through faith in Jesus Christ, whose blood actually cleanses from sin.

This also means the Supper should never be detached from preaching and teaching. The elements do not explain themselves to a careless heart. Scripture gives them their meaning. Bread and cup can be handled with great ceremony and still be misunderstood if the cross is not plainly proclaimed. A simple church gathering, with ordinary bread and an ordinary cup, honors Christ when the Word of God defines the act and the people receive it with faith.

Remembrance also guards the church from drifting into personality worship. No pastor, priest, worship leader, tradition, or emotional atmosphere belongs at the center of the table. The Lord said, “in remembrance of Me.” Communion keeps moving the eye of faith away from human performance and back to Jesus Christ crucified, risen, and coming again.

Hebrews is decisive. Christ’s sacrifice is not repeated, continued, or completed by church ritual. Under the old covenant, priests stood daily because their sacrifices could not finally remove sin. Jesus offered Himself once, and His work is complete.

The posture matters. Old covenant priests stood because the work continued. Christ sat down because the offering was finished. Communion must be interpreted under that truth. It cannot be a repeated propitiatory sacrifice. It cannot keep Christ’s offering going. It cannot make the cross effective again. The cross is already effective because Christ’s blood was actually shed and His offering was accepted by the Father.

This is why transubstantiation and any repeated-sacrifice view must be rejected. If communion is treated as a fresh offering of Christ’s body and blood, the table is being made to say what Hebrews denies. The Lord’s Supper is holy and powerful as remembrance and proclamation, but its power is not that it re-sacrifices Jesus. Its power is that it points God’s people to the one sacrifice that is forever sufficient.

John 6 is often brought into discussions about communion because Jesus speaks strongly about eating His flesh and drinking His blood. But the setting is not the upper room. John 6 is a public teaching after the feeding of the five thousand, where Jesus confronts people who want bread but do not truly believe in Him.

The chapter itself explains the image by coming and believing. Jesus is not teaching cannibalism, and He is not instituting the Lord’s Supper in John 6. He is calling sinners to receive Him by faith as the only source of life. Later He says plainly that His words are spirit and life.

John often records Jesus using physical pictures for spiritual realities: new birth, living water, bread of life, light, door, shepherd, vine. The images are vivid because the truths are weighty. Communion is connected to Christ’s body and blood, but John 6 should not be pulled out of context to overturn the plain once-for-all teaching of Hebrews or the remembrance language of Luke and 1 Corinthians.

Communion is corporate remembrance, not private remembrance alone. It is shared remembrance in the gathered body. Paul uses the language of communion, or fellowship, when speaking about the cup and the bread.

The word communion carries the idea of fellowship or participation. This does not mean the elements become Christ’s physical body and blood. It means the church shares together in the meaning and benefits of Christ’s sacrifice by faith. The table visibly confesses that believers are not saved as isolated religious consumers. We belong to one Lord, one gospel, and one body.

That is why division, pride, and contempt are so ugly at the Lord’s table. The bread and cup proclaim a crucified Savior who purchased His people by His blood. To handle that meal while despising Christ’s people is to contradict the message of the meal.

The Corinthian church was taking the Lord’s Supper in a way that denied what it proclaimed. Some were indulging themselves while others were shamed. Their gathering displayed selfishness instead of unity. Paul warns them sharply.

Paul does not say only sinless people may partake. If sinlessness were required, the table would be empty. He warns against an unworthy manner: irreverence, hypocrisy, selfishness, division, and refusal to take seriously what the Supper proclaims. Self-examination is not meant to trap a believer in endless fear. It is meant to bring honesty before God.

The warnings are serious. Some in Corinth were weak, sick, and some had died. But Paul also explains the difference between the Lord’s discipline and the world’s condemnation.

This does not deny eternal security. It shows that the Father disciplines His children. A true believer is secure in Christ, sealed by the Spirit, and kept by God. That security is not permission to treat holy things casually. The same grace that saves us also trains us to confess sin, make peace where we can, and come to the Lord’s table with reverence.

It is possible to reject transubstantiation and still speak too lightly. Communion is not a bare object lesson that could be replaced by any illustration we prefer. Jesus chose bread and the cup. He attached them to His body and blood. He commanded His people to continue this remembrance. That gives the ordinance weight, even though the elements remain bread and the fruit of the vine.

It is also possible to react against empty symbolism by giving the elements a power Scripture does not give them. The bread does not become the physical body of Christ. The cup does not become His physical blood. Christ is bodily risen and seated at the right hand of the Father. The believer feeds on Christ by faith, not by a physical change in the elements. The table is meaningful because Christ’s sacrifice is real, finished, and received by faith.

Views often called consubstantiation or sacramental presence try to avoid some problems while still locating Christ’s body and blood in, with, or under the elements. The safer biblical language is the language Scripture gives: remembrance, proclamation, communion, self-examination, and hope until He comes. We should not be wiser than the Lord’s own words.

Come first by faith in Christ. The Lord’s table is not a substitute for conversion. If a person has not trusted Christ, the need is not bread and cup but repentance and faith in the crucified and risen Savior. Communion proclaims the gospel, but eating and drinking do not save apart from believing in Jesus.

Come with remembrance. Think about His body given for you and His blood shed for you. Do not let the moment pass as routine. The Son of God suffered in the body, shed real blood, died a real death, and rose again. The bread and cup call the church to put that truth back in the center with grateful faith.

Come with examination and confession. If the Lord brings sin to mind, agree with Him. Confession is not bargaining with God. It is telling the truth before the One who already knows. The believer’s confidence is not in self-cleansing but in Christ’s blood.

Self-examination should be honest, but it should not become a refusal to come to Christ. Some believers hear Paul’s warning and conclude they should stay away whenever they feel unworthy. But the table is not for people who have earned a place. It is for believers who are trusting the worthy Savior. If the Spirit convicts you of sin, do not hide behind absence. Confess, repent, seek reconciliation where needed, and come remembering the blood that cleanses.

Come with love for the body. If you are nursing bitterness, despising another believer, or using the gathering to display pride, hear Paul’s warning. Communion is not a private spiritual moment detached from the church. It proclaims one body around one Savior.

Come with hope. Paul says the church proclaims the Lord’s death till He comes. The table looks backward and teaches the church to wait. The crucified Savior is risen. The risen Savior will return. Until then, the bread and cup keep telling the truth: Christ died for our sins, His sacrifice is enough, and He is coming again.
