First Corinthians 5:7 tells believers to clear out the old, corrupting influences in their lives because they already belong to a new, purified community. The reason given is that Christ, the true Passover lamb, has already been sacrificed for them. Paul wrote this letter to the church in Corinth, a congregation he had founded and was now correcting for tolerating a serious sexual sin within its fellowship.
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.

What 1 Corinthians 5:7 Means
Paul begins with a command: “purge out the old yeast.” Yeast works quietly through dough, and a small amount affects the whole batch. Paul uses that picture to warn that a tolerated sin, or a habit of pride, spreads through a church just as yeast spreads through bread. The word “purge” means to thoroughly clean out or remove, not merely to tidy up around the edges.
The next phrase, “that you may be a new lump, even as you are unleavened,” adds a surprising twist. Paul does not say the Corinthians must first become unleavened in order to be made new. He says they already are unleavened, and so they should act like the people they have become. The verse describes an identity they have received, and it calls them to live consistently with it.
The verse does not promise that a church will never face sin, nor does it describe how any particular discipline should unfold. It gives a reason and a direction: because Christ has been sacrificed, the community should remove what contradicts that sacrifice.
The Context of 1 Corinthians 5:7
First Corinthians is one of Paul’s letters to a church he planted in the Greek city of Corinth, a busy port known for its moral looseness. The letter responds to reports of divisions, lawsuits, and a man living with his stepmother. In chapter 5, Paul is angry that the congregation is proud of its tolerance when it should be grieving. Just before verse 7, he has told them to remove the offender from their fellowship, and he calls their boasting “not good” because a little yeast leavens the whole lump.
Read in that setting, verse 7 is a practical command about church discipline wrapped in a theological foundation. The Corinthians are told to clean house because their identity rests on Christ’s death, not on their own success at being pure. The verses that follow, 8 through 10, push the same point further by urging them to celebrate the feast with sincerity and truth rather than malice and wickedness.
Key Phrases in 1 Corinthians 5:7
Exodus 12:14
This day shall be to you for a memorial, and you shall keep it a feast to the LORD: throughout your generations you shall keep it a feast by an ordinance forever.

This verse establishes the Passover as a lasting memorial for Israel. Reading it alongside 1 Corinthians 5:7 shows how Paul draws on that festival to explain what Christ has accomplished.
2 Corinthians 5:17
Therefore if anyone is in Christ, he is a new creation. The old things have passed away. Behold, all things have become new.
(WEB)
Paul again speaks of newness in Christ, describing the believer as a new creation. It helps explain the “new lump” language in the earlier letter by showing that the change is real and comes from God.
A Short Prayer From 1 Corinthians 5:7
Lord Jesus, you were sacrificed for me so that I could be set free and made new. I confess the old habits and attitudes I still hold onto, and I ask you to show me what needs to be cleared out of my life. Give our church the courage to deal honestly with sin and the humility to receive your grace together. Help me live in a way that matches the new life you have already given me. Amen.
