First Corinthians 5:7 tells believers to clear out the old, corrupt habits in their lives so they can live as the new people they already are. The verse grounds that call in the fact that Christ, our Passover, has been sacrificed for us. Paul wrote this line to the church in Corinth, a congregation that had tolerated a serious sexual sin among its members and was proud of its own tolerance.
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: clear out the old yeast. In the Jewish calendar, leaven was removed from every home before the Passover meal, because bread made with yeast was not to be eaten during that feast. Paul uses this picture to describe sin as a small, spreading influence that changes the whole community, just as a little yeast works through an entire batch of dough. The command is direct: get rid of it.
The next phrase tells the Corinthians what the removal is for. They are to become a new lump, meaning a fresh batch, because they are already unleavened. Paul is not asking them to become something they are not. He says they already belong to a new condition in Christ, and their behavior should line up with that reality. The verse does not promise that obedience will be easy or that believers will never struggle again. It describes who they are and what that identity asks of them.
The verse closes with its reason: Christ has been sacrificed in our place. The Passover lamb was killed so that Israel’s firstborn would be spared, and Paul says Christ fills that role. The sentence is a statement of fact about what Christ has done, and the call to holiness rests on it.
The Context of 1 Corinthians 5:7
First Corinthians was written by the apostle Paul to a church he had founded in the Greek city of Corinth, a busy port with a reputation for moral laxity. The letter addresses divisions, disorder and several moral problems within the congregation. Chapter 5 deals with a man who was living with his stepmother, and the church had not disciplined him. Paul is angry that they boasted about their open-mindedness when they should have grieved.
Verses 4 through 6 call the church to act together in the name of Jesus, and verse 6 uses the yeast image to warn that their pride is spreading through the whole group. Verse 7 is the turning point: the same yeast that must be cleared out is now joined to the good news of Christ’s sacrifice. Verse 8 then pushes the image further, urging a feast marked by sincerity and truth. Read this way, verse 7 is less a general call to self-improvement and more a specific instruction to a church that needed to deal with sin as a community.
Key Phrases in 1 Corinthians 5:7
Romans 6:4
We were buried therefore with him through baptism into death, that just as Christ was raised from the dead through the glory of the Father, so we also might walk in newness of life.
(WEB)
Paul explains in Romans that believers have been buried with Christ and raised to walk in newness of life. This parallels the call in 1 Corinthians 5:7 to become a new lump, showing that renewal flows from our union with Christ rather than from our own strength.
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)
This verse states plainly that anyone in Christ is a new creation, which gives the call to clear out the old yeast its foundation. Paul’s language about newness in both letters shows that the change he describes is real and comes from God.
A Short Prayer From 1 Corinthians 5:7
Lord, you know the old habits I still carry, the small attitudes that spread quietly through my thoughts and words. Show me what needs to be cleared out, and give me the courage to deal with it honestly. Thank you that Christ, our Passover, has been sacrificed for me, so my life does not depend on my ability to be perfect. Help me to live as the new people you have already made me, and let my choices reflect the freedom that comes from your grace. Amen.
