Short answer: In 1 Corinthians 5:7 Paul tells the Corinthian church to purge out the old yeast so that they may be a new lump, because Christ, their Passover, has been sacrificed in their place. The verse ties the death of Jesus to the Passover lamb and treats that death as already accomplished, not as something the church completes. Because the sacrifice has happened, the church is to remove the old yeast of malice and wickedness and live as unleavened bread of sincerity and truth. The verse is a reason for moral seriousness and church discipline, not a ritual theory.
The Passover setting behind Paul's command
First Corinthians 5 is a pastoral letter, not a proverb collection, and 5:7 sits inside an argument Paul builds from a real report. A man in the congregation was living with his father's wife, and instead of mourning, the church was boasting. Paul has already told them to hand such a person over to Satan for the destruction of the flesh, with the stated hope that the spirit may be saved in the day of the Lord Jesus. That hope matters for how the verse is read. The command to cleanse comes from a pastor grieving over sin, not from a court pronouncing a sentence.
The literary shape of 5:7 is a command followed by its reason. Paul tells the church to purge out the old yeast so that they may be a new lump, then grounds the command in a fact about Christ: he says "Purge out the old yeast, that you may be a new lump, even as you are unleavened. For indeed Christ, our Passover, has been sacrificed in our place." The surrounding sentences keep the same picture going. Just before, Paul asks whether a little yeast leavens the whole lump. Just after, he calls the church to keep the feast with sincerity and truth.
The Passover imagery is drawn from Israel's covenant life, where families cleared leaven from their homes before the feast and a lamb was slain. Paul takes that Exodus pattern and applies it to a congregation that must not tolerate corrupting sin in its midst. The comparison is extended, not decorative: leaven spreads, and so does tolerated wrongdoing. Yet the aim Paul states earlier is the saving of the spirit, so the clearing is meant to be done with mourning, humility, and hope of restoration rather than harsh exclusion. The pattern shapes the church's life because Christ, the Passover, has already been sacrificed.
The command and its reason belong together. Paul does not ask the church to become unleavened in order to earn Christ's sacrifice; he says they already are unleavened because Christ has been sacrificed. The cleansing is a response to what God has done, not a condition for it. That order keeps the passage from becoming a pretext for severity. A church that clears away corrupting influence while forgetting the sacrifice behind the command will miss Paul's point, and a church that tolerates the leaven while boasting in grace will miss it too.
Christ, our Passover, has been sacrificed
Paul writes to a church that has been boasting while tolerating a scandal in its midst, and he turns to the imagery of Israel's exodus. The word he uses names the annual festival and the lamb slain at its center, so he is not offering a loose comparison but identifying Christ with the whole observance. The rescue from Egypt, the blood on the doorposts, the meal eaten in haste, all of it finds its focus in Jesus. What Israel celebrated year after year as a memorial, Paul says, has reached its goal in a person, and that person belongs to this mixed congregation of Jews and Greeks.
The verb has been sacrificed is past and completed. Paul is not describing something the church performs or repeats but an event already accomplished at the cross, once for all. That is why the next sentence can call the community to a feast. The command Purge out means to remove, and it echoes the household practice of sweeping out every trace of leaven before Passover began. The old yeast here is malice and wickedness; the new loaf is sincerity and truth. The call to holiness rests on a finished sacrifice, not on a ritual the Corinthians must somehow reenact.
Notice the small word our. The Passover belongs to this community, Jew and Gentile together in Christ, a shared possession rather than a private devotion. That matters for how the removal of leaven is carried out. Paul's stated aim in the surrounding verses is not the destruction of a person but the saving of the spirit, and the congregation is to mourn rather than boast. Where this passage is used to justify harsh exclusion, leaders should remember that discipline in Paul's hands is grief-stricken, humble, and aimed at restoration, never at triumph over a fallen brother.
Christ our Passover has been sacrificed
Paul writes this line into a mess, not a calm discussion. A man in the congregation was living with his father's wife, and the church was boasting instead of mourning. Paul had already told them to hand such a person over to Satan for the destruction of the flesh, so that the spirit might be saved in the day of the Lord Jesus (5:5). Then he turns their boasting into an image: a little yeast works through the whole batch. The point is not the individual's sin alone but what tolerating it does to the whole community. Paul's stated aim in the handing over is rescue, not revenge.
The Passover background is concrete. Israel cleared leaven out of its homes before the feast, and a lamb was slain. Paul takes that Exodus pattern and applies it to a church: purge out the old yeast so that you may be a new lump, since you really are unleavened. Then he gives the reason: Christ, our Passover, has been sacrificed in our place (5:7). The wording matters. The sacrifice is already accomplished, not something the Corinthians repeat or complete. Because the lamb has been slain, the leaven must go. Cleansing is the fitting consequence of a finished work, not a way of earning it.
Verse 8 draws the application out: keep the feast, not with old yeast, neither with the yeast of malice and wickedness, but with the unleavened bread of sincerity and truth. This is not a theory about rituals but a call to a purified common life. It is also where leaders must be careful. Paul's aim in 5:5 is the saving of the spirit, and the removal he commands is a mourning act, not a license for harshness. Discipline here is carried out with grief over sin and hope of restoration, never with the malice the same verse names.
Where readers disagree about the leaven and the purging
Paul builds the call to holiness on a fact, not a feeling: Christ, our Passover, has been sacrificed in our place (1 Corinthians 5:7). Evangelical readers agree on that anchor. They differ over how far to press the imagery. Some treat leaven as a fixed code word for sin wherever it appears. Others point out that Jesus used leaven for the kingdom in the Gospels, so the symbol takes its meaning from the sentence around it. Here the context decides: Paul names malice and wickedness in 5:8, and the leaven is the boasting and tolerance of sin already described in the congregation.
The command to purge out the old yeast raises a second disagreement. Some readers hear in it a warrant for formal church discipline, with public steps and removal from membership. Others take it as informal separation, a refusal to keep company with a professing believer who persists in sin. Verse 9 and the verses that follow show Paul making a distinction: he means company with those who claim the name of Christ, not a withdrawal from outsiders. The verse itself commands the purging but prescribes no procedure, no timeline, and no committee. It also promises no outcome, neither a healthy church nor a restored person in this life.
What stays central is the sacrifice already made and the inconsistency of boasting in sin while naming Christ. Because this text is often used to justify harsh exclusion, leaders should hold two things together. Paul's aim in the case behind this chapter is the saving of the spirit, and the removal is meant to be carried out with mourning, humility, and hope of restoration, not triumph. The verse gives no permission for cruelty, and it offers no guarantee that discipline will succeed. It calls a church to sincerity and truth, and it leaves the results with the Lord who was sacrificed for them.
Christ, our Passover, has been sacrificed
Paul makes a direct identification here that he does not soften or explain: Christ is our Passover. The old feast remembered a lamb whose blood marked a house so that death passed by, and a people who left slavery behind. Paul does not walk through the mechanics of atonement in this verse. He states a fact and moves on. The sacrifice has already happened, and it belongs to the church, not to a distant story. That is the gospel pattern the Exodus carried all along: a lamb dies, a people is spared, and those spared are led out to live differently.
Notice the tense Paul uses. The sacrifice is finished, and the bread the church now eats is sincerity and truth. Paul is not inventing a symbol; he is reading Israel's story as one that was always pointing forward. The lamb was never the point in itself. It pointed to a deliverance God would accomplish himself. So when Paul says Christ our Passover has been sacrificed, he is telling a quarreling church that their identity rests on something already done for them, not on their own party loyalties or their boasting about who they follow.
This verse does not stand alone. Earlier in the chapter Paul speaks of the day of the Lord Jesus, tying the death of Christ to His return. The church lives between the finished sacrifice and the coming day, and that in-between shapes how discipline is done. Paul's stated aim in the same passage is that a spirit may be saved, not that a person be thrown away. Leaders who use this chapter to justify harsh exclusion should read the whole argument. The lamb was slain to spare and restore, and correction in the church should carry that same hope.
Keeping the feast with sincerity and truth
Paul's command to cleanse comes after the announcement that the sacrifice has already been made. That order matters in ordinary life. A believer does not sweep sin out of a household or a friendship in order to become acceptable; the acceptance is already secured by Christ. The cleansing is gratitude in motion. So the honest question is not whether sin is present somewhere in general, but where a tolerated habit or compromise is quietly leavening a specific relationship, a family pattern, a church's common life. Paul's image is yeast, not an explosion: small, working, spreading. Naming that honestly before God is the first act of response, and it is a response to grace, not a bid for it.
The manner matters as much as the act. Paul sets malice and wickedness against sincerity and truth, which means the removal of an obvious fault is not the whole goal. A person can cut off a friendship in the name of purity and leave the yeast of bitterness untouched. Churches can practice discipline and forget that their own standing is entirely in Christ, that they too are unleavened only because of him. The stated aim in this passage is not expulsion for its own sake but the saving of a spirit on the day of the Lord. That aim should shape the tone: mourning rather than triumph, humility rather than superiority, and a genuine hope of restoration.
Verse 8 gives the positive shape of the response: keep the feast with sincerity and truth. That is ordinary conduct, not merely the absence of scandal. It looks like plain speech instead of flattery, keeping promises, refusing to let resentment sit unaddressed, and being the same person in private as in public. None of this comes with a guarantee that every hard conversation ends well in this life. A household may still fracture, a friendship may still cool. What stays fixed is the finished sacrifice. The feast is kept in light of that, not in exchange for it.
Biblical fidelity check
Paul writes to a church that was boasting about a man living with his father's wife, and he reaches for the Exodus story to expose the problem. The command to clear out old yeast echoes what Jewish households did before Passover, removing every trace of leaven from the house. Paul reads that practice as a picture of the community's life together. The interpretive risk here is treating leaven as a fixed code word for sin in every biblical text, when the Gospels sometimes use it for the kingdom. Context, not the symbol alone, decides the meaning. The verse itself gives no procedure for removal.
Evangelical readers agree Paul anchors Christian conduct in Christ's completed sacrifice, but they differ over what "purge out" authorizes in a congregation, whether formal discipline or informal separation, and 5:9–13 shows Paul distinguishing company with professing believers from contact with outsiders. The verse prescribes no process, and it promises neither a healthy church nor a restored person in this life. What stays central is that Christ, our Passover, has been sacrificed, and a church bearing His name cannot boast in sin.
Studies that take up 1 Corinthians 5:7 from another angle
For further study, trace the Passover institution and its deliverance context in 1 Corinthians 5: Church Discipline and the Passover Lamb, read how the Gospels place the crucifixion at Passover in 1 Corinthians 1: Called, United, and Boasting in the Lord, follow Paul's argument about the old and new lump through the rest of the chapter in 1 Corinthians 10: Warnings and Freedom, and consider how the New Testament elsewhere speaks of Christ's sacrifice in 1 Corinthians 11: Order, Unity, and the Lord's Supper.
Frequently asked questions
Why does Paul call Christ our Passover lamb in 1 Corinthians 5:7?
Paul names Christ our Passover because the Corinthians were tolerating an arrogant man in the church, and he tells them to clear out the old yeast since Christ, the true Passover, has already been sacrificed. In the Passover story, a lamb was killed and its blood marked the house so judgment passed over, and Israel then removed all leaven and ate the feast. Paul takes that picture and says the reality has arrived: the sacrifice is finished, so the congregation's response is to become a new lump, putting away malice and wickedness and keeping the feast with sincerity and truth.
What does it mean for a church today to purge out the old yeast?
In 1 Corinthians 5:7 the command to purge out the old yeast means the gathered church is to remove the corrupting influence it had been tolerating, because a little yeast works through the whole lump (5:6). Paul grounds this in Christ, our Passover, already sacrificed, so cleansing is a response to grace already given, not a means of earning it. Practically, a church clears out old yeast by naming sin honestly, refusing to boast in it, and restoring the sincerity and truth that leaven of malice and wickedness displaces (5:8). The aim throughout the passage is not humiliation but the saving of the spirit in the day of the Lord (5:5).
How does the Passover lamb in Exodus connect to Jesus in the New Testament?
Paul tells the Corinthians that Christ, our Passover, has been sacrificed in their place, so the ancient lamb and Jesus are one story. In Exodus the lamb's blood marked a household for rescue from judgment; here Paul names Christ as the one sacrificed on behalf of his people. That finished sacrifice then shapes how the church lives, since Paul urges them to clear out the old yeast and keep the feast with sincerity and truth. The connection is both rescue and response.
