Outline: Dealing with Immorality in the Church
I. The Problem: A Scandalous Immorality (vv. 1-2) A. Report of Fornication (v. 1a) 1. Such as is not so much as named among the Gentiles. 2. That one should have his father’s wife cf. Leviticus 18:6ff.; 19:17; Luke 17:3-4 B. The Corinthian Church’s Response: Arrogance, not Humiliation (v. 2) 1. They are puffed up. 2. They have not mourned. 3. The offender is not taken away from among them.
II. Paul’s Judgment and Command (vv. 3-5) A. Paul’s Judgment as if Present (v. 3) 1. Absent in body, but present in spirit. 2. Judged already concerning him that hath done this deed. B. The Assembly’s Authority and Action (v. 4) 1. In the name of our Lord Jesus Christ. 2. When ye are gathered together, and my spirit. 3. With the power of our Lord Jesus Christ. C. The Sentence: Deliverance unto Satan (v. 5) 1. For the destruction of the flesh. 2. That the spirit may be saved in the day of the Lord Jesus. Cf. Matthew 18:15ff.
III. The Leaven Analogy: Purity of the Church (vv. 6-8) A. Boasting in Sin is Not Good (v. 6) 1. Your glorying is not good. 2. A little leaven leaveneth the whole lump. B. Christ Our Passover Sacrificed (v. 7) 1. Purge out therefore the old leaven (cf. Exodus 12:14-15). 2. That ye may be a new lump, as ye are unleavened. 3. For even Christ our passover is sacrificed for us. C. The Feast of Sincerity and Truth (v. 8) 1. Let us keep the feast. 2. Not with old leaven, neither with the leaven of malice and wickedness. 3. But with the unleavened bread of sincerity and truth.
IV. Clarification on Association (vv. 9-11) A. Previous Letter’s Instruction (v. 9) 1. I wrote unto you in an epistle. 2. Not to company with fornicators. B. Not the World’s Fornicators (v. 10) 1. Yet not altogether with the fornicators of this world, or with the covetous, or extortioners, or with idolaters. 2. For then must ye needs go out of the world. C. The Present Command: A Brother in Sin (v. 11) 1. But now I have written unto you not to keep company. 2. If any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner. 3. With such an one no not to eat.
V. The Church’s Internal Responsibility (vv. 12-13) A. Judging Those Within (v. 12) 1. For what have I to do to judge them also that are without? 2. Do not ye judge them that are within? B. God Judges Those Without (v. 13a) 1. But them that are without God judgeth. C. The Final Command: Put Away Wicked Person (v. 13b) 1. Therefore put away from among yourselves that wicked person.
Cleansing Out the Old Leaven
“Your glorying is not good. Know ye not that a little leaven leaveneth the whole lump? Purge out therefore the old leaven, that ye may be a new lump, as ye are unleavened. For even Christ our passover is sacrificed for us.” 1 Corinthians 5:6-7 (Read vv. 1-13)
In this powerful chapter, Paul addresses a truly shocking situation within the Corinthian church: open and unrepentant immorality. What is even more alarming than the sin itself is the church’s response, or, more accurately, the lack thereof. They were “puffed up” and arrogant, rather than sorrowful and concerned for the purity of their fellowship and the soul of the offender.
Paul’s message is unequivocal: this kind of blatant sin cannot be tolerated within the body of Christ. He calls for decisive action, not out of malice, but out of a deep concern for the spiritual health of the entire congregation, as well as the one who had sinned. The analogy he uses is profoundly insightful: “A little leaven leaveneth the whole lump.”
Think about how leaven works. A small amount of yeast can cause an entire batch of dough to rise and expand. Similarly, a small amount of unaddressed sin, especially scandalous sin, can permeate and corrupt the entire community of believers. It can normalize what is abnormal, desensitize hearts to wickedness, and ultimately damage the church’s witness to the world (cf. Revelation, chapters 2-3).
Paul reminds the Corinthians that “Christ our passover is sacrificed for us.” This is a direct reference to the Jewish Passover, during which the Israelites were required to remove all leaven from their homes before observing the feast. Christ, our true Passover Lamb, has been sacrificed to cleanse us from the leaven of sin. Therefore, as believers, we are called to live as “unleavened bread” — in sincerity and truth, free from malice and wickedness.
This doesn’t mean we are perfect, but it does mean we are to be intentional about pursuing holiness and addressing sin when it rears its head within our fellowship. It’s not about being judgmental of outsiders, as Paul clarifies in verses 12-13. Our primary responsibility is to maintain the purity and integrity of the church, the assembly of believers.
Prayer: Heavenly Father, we thank You for the sacrifice of Your Son, Jesus Christ, our Passover Lamb, who cleanses us from all sin. Forgive us for the times we have tolerated leaven in our lives or in Your church. Grant us discernment, humility, and courage to “purge out the old leaven,” that we may walk in sincerity and truth. Help us to guard the purity of Your church, for Your glory alone. In Jesus’ name, Amen.
Reflection Questions
What “leaven” might be present in our lives or within our church community that needs to be purged out?
How can we, as individuals and as a church, cultivate a greater sense of humility and a genuine mourning over sin, rather than arrogance or indifference?
In what ways does our commitment to purity demonstrate the truth that “Christ our passover is sacrificed for us”?
