1 Corinthians 5:7

What does 1 Corinthians 5:7 mean?

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 short answer

In 1 Corinthians 5:7, Paul reaches for one of the most vivid pictures in Israel's story: the Passover. Every year, Jewish households did two things to keep the feast. They sacrificed a lamb, and they searched the house to remove every trace of leaven—the fermenting agent in old dough. Paul takes both halves of that festival and applies them to the church in Corinth.

The striking move is his tense. Christ, our Passover, "has been sacrificed." The lamb part of the festival is already done. What remains is the housecleaning. That is why the verse opens with a command: "purge out the old yeast." In the situation Paul is addressing, the leaven stands for wrongdoing tolerated inside the community—specifically a case of serious sexual sin the Corinthians had been shrugging off. The church, Paul says, should live like a house prepared for Passover: swept clean, because the lamb has already been slain.

The Exodus background sharpens the point. In Exodus 12, the Passover lamb was not primarily a sacrifice to atone for sin. Its blood marked the houses God "passed over" in Egypt, setting apart a people delivered from slavery by God's power. So when Paul calls Christ our Passover, he is saying the church has been marked out as a rescued, distinct people—and its shared life should look like it. The command and the identity sit side by side: clean out the old yeast "even as you are unleavened." Become what you already are.

There is also something here that resists tidy explanation. That the death of Jesus becomes the church's Passover is, in the language of the Pauline tradition, a mystery—not a puzzle to be solved but a gift to be received, trusting that God's ways run deeper than our reasoning.

Bruce Fisk answers a question many readers bring to this verse—what kind of sacrifice is the Passover lamb?—by showing from Exodus 12 that it marks out a people delivered by God rather than atoning for sin, which is why the church's remaining task is removing the leaven. Molly Marshall traces the word "paschal" back to God's protecting act of passing over Israel in Egypt, and reflects on Christ's death as a mystery received rather than solved.

“Christ, as the Passover lamb, has already been sacrificed (cf. Exod. 12:3–7), so the time is at hand for the Corinthians to carry out the other major part of the festival, searching out and removing all “leaven” (symbolizing the wrongdoer) from their household (Exod. 12:15). It is important to be clear about the function of the Passover lamb. This is not a sacrifice to atone for sin; rather, it symbolizes the setting apart of Israel as a distinct people delivered from slavery by God’s power. “And when your children ask you, ‘What do you mean by this observance?’ you shall say, ‘It is the passover sacrifice to the Lord, for he passed over the houses of the Israelites in Egypt, when he struck down the Egyptians but spared our houses’ ” (Exod.”

“The etymology of “paschal” is linked to “passing over,” a fundamental concept in the Hebrew Bible describing God’s protection of Israel in Egypt (Exod. 12:13, 21–27). The slaughtered lamb is the paschal sacrifice, and this language is later a description of the death of Jesus (1 Cor. 5:7). To speak of mystery, as the Pauline tradition often does, is to acknowledge that things of God transcend human rationality. Mystery is not something we solve as much as receive as gift, believing that God’s ways are truly higher than ours. Part of our calling in Christ is to be “stewards of the mysteries” (1 Cor. 4:1–2). There is no greater mystery than the confession that through the suffering of the Son we are made whole.”

This verse turns deliverance into a to-do list of exactly one item: housecleaning. If Christ's sacrifice has already happened, then the question for a community—or a single life—is whether anything corrosive is being quietly tolerated inside the house. Leaven works the way habits and compromises work: a little of it spreads through the whole batch.

The encouragement is that the command rests on a finished fact. You are not cleaning house to earn deliverance; you are cleaning house because deliverance has already come. Belonging comes first, and the swept-out life is simply what belonging looks like.

First Corinthians 5 confronts a scandal: a man in the church is involved with his father's wife, and rather than grieving, the congregation seems proud of its tolerance. Paul insists the community cannot absorb this without consequence, calling for the man's removal for the sake of both the church and, ultimately, the man himself. Verse 7 supplies the theological logic: a little leaven spreads through the whole lump, and a Passover people—marked out by a lamb already sacrificed—must keep the feast with sincerity and truth rather than with the old yeast of malice.
