Episode 181 - "Get the leaven out!" - 1 Corinthians 5:6-13

1Cor. 5:6 Your boasting is not good. Do you not know that a little leaven leavens the whole lump? 7 Cleanse out the old leaven that you may be a new lump, as you really are unleavened. For Christ, our Passover lamb, has been sacrificed. 8 Let us therefore celebrate the festival, not with the old leaven, the leaven of malice and evil, but with the unleavened bread of sincerity and truth.

1Cor. 5:9 I wrote to you in my letter not to associate with sexually immoral people— 10 not at all meaning the sexually immoral of this world, or the greedy and swindlers, or idolaters, since then you would need to go out of the world. 11 But now I am writing to you not to associate with anyone who bears the name of brother if he is guilty of sexual immorality or greed, or is an idolater, reviler, drunkard, or swindler—not even to eat with such a one. 12 For what have I to do with judging outsiders? Is it not those inside the church whom you are to judge? 13 God judges those outside. “Purge the evil person from among you.”

This episode picks up where we left off last week. Paul is addressing in this letter with the Christians at Corinth that he has received a report that there is known sexual immorality by someone in their church, and they are not doing anything about it. Specifically, Paul says, “a man has his father’s wife.” Paul points out that even this kind of immorality is “not tolerated among the pagans.” (1 Cor 5:1) Paul counsels them to remove him from the fellowship of the church. While this seems a bit harsh on the surface. Paul’s suggestion that they “hand him over to Satan” (1 Cor 5:5) has the intent that this man, living as he wants, not in the Spirit-dwelt church, will experience the consequences of his rebellion, that his “flesh” will be destroyed, but his “spirit may be saved in the day of the Lord.” (1 Cor 5:5) Paul does not want judgment to come upon this person. He wants him to be saved. Furthermore, Paul wants the church to testify to and exemplify God’s holiness, grace, love, and unity. They cannot do that while they are manifesting arrogance and disregarding egregious sin among them.

Paul uses a simple but powerful illustration of bread. He says, “a little leaven leavens the whole lump.” (1 Cor 5:6) I get this. I love to bake, and I love to bake bread. If I’m baking a normal loaf of white bread, it doesn’t take much yeast mixed in with the ingredients in order for the lump of dough to expand quickly and significantly. Paul suggests that’s how sin works in a community where only a little is allowed to remain. It doesn’t take long before it has an effect on the whole community.

So, what does Paul mean in verse 7 by saying, “clean out the old leaven that you may be a new lump, as you really are unleavened. For Christ, our Passover lamb, has been sacrificed?” What does Christ being our Passover lamb have to do with leaven or being unleavened and this situation at Corinth? The answer lies in the Hebrew Scriptures. Look at Exodus 12:14-15

“This day shall be for you a memorial day, and you shall keep it as a feast to the LORD; throughout your generations, as a statute forever, you shall keep it as a feast. 15 Seven days you shall eat unleavened bread. On the first day, you shall remove leaven out of your houses, for if anyone eats what is leavened, from the first day until the seventh day, that person shall be cut off from Israel.”

The Israelites had been in bondage in Egypt, and the LORD was preparing to deliver them from that bondage. In the final plague upon the land the LORD would bring to cause this, the Israelites were instructed to sacrifice a perfect lamb, apply some of its blood on the outside door frame and enter into their homes and consume the roasted meat of this lamb if they wanted to be spared the loss of their firstborn. Furthermore, the Israelites were instructed to commemorate God’s deliverance every year. Paul is informing them the principle within this commandment to the Israelites has application within the church. Leaven is a picture of sin. Christ’s sacrifice on the cross liberated us from the power of that sin. Therefore, having experienced that liberty and not wanting to mock that great sacrifice, we should earnestly desire not to have any of that “old leaven” anywhere in our house. The man’s defiant immorality is mocking the sacrifice of Christ, and the arrogance of the church is condoning it by not removing the old leaven.

Our worship requires “sincerity and truth.” Like with the Israelites, removing every atom of leaven is impossible. Returning to my personal experience making sourdough bread in which I add no yeast whatsoever. The bread is leavened through the fermentation of the starter. This was likely what the Israelites had when they did make leavened bread. They didn’t have packs of yeast to carry around with them. Over time the microscopic spores from this fermentation are around the house. You can’t see them. So, you can’t perfectly get rid of it all. But, one can sincerely pursue the cleansing. This is what the church is supposed to do. Paul is saying to the Corinthians, you need to sincerely strive to not let sin remain in the house.

Paul makes an important qualification about this beginning in verse 9. Notice that Paul had written a letter to them before. Yet we call this letter 1 Corinthians. Obviously, this isn’t Paul’s first letter to them. It is the first that has been preserved and considered by the church as valuable and even God-inspired. The point of verses 9-13 is that the church cannot hold the world accountable to the standards God has for them. They cannot avoid speaking with and interacting with unbelievers outside the church. We could not fulfill the Great Commission if we did entirely avoid unbelievers.

God is the true judge of all humanity. The church must hold itself accountable for sincerely pursuing a life in keeping with God’s truth. The church needs to stand out as “different” from the culture around it and be a light in a dark world.

Lord - Give us a heart to pursue righteousness and humility before you and others.
