1 Corinthians Chapter 5 – Commentary and Explanation Bible Study
I have to be honest… this chapter is tough. It’s not soft or cozy. It’s one of those that hits hard because it deals with sin, correction, and purity inside the church — things we often avoid talking about. But Paul doesn’t skip the uncomfortable. He walks right into it, because truth matters just as much as grace.
The Corinthian church was a gifted church — they spoke in tongues, had knowledge, enthusiasm, all the stuff that looks spiritual on the outside. But inside, they had a serious problem — and worse, they were proud about it.
So Paul writes like a father whose heart is breaking for his kids who don’t see how serious things have become.
Verse 1–2: Sin That Even the World Is Shocked By
Paul starts straight:
“It is actually reported that there is sexual immorality among you, and of a kind that does not occur even among pagans: a man has his father’s wife.”
That’s a jaw-drop moment. Even the non-believers in Corinth — a city known for being wild and immoral — were shocked.
But what’s worse? Paul says, “And you are proud!”
Can you imagine that? Instead of being heartbroken, the church was puffed up — maybe they called it “grace,” maybe they thought, “We’re not legalistic; we’re loving.”
But love that ignores sin isn’t love — it’s apathy.
Paul’s tone is not angry because of the sin itself, but because the church was tolerating it, protecting it, maybe even calling it “freedom in Christ.”
That’s dangerous. Because grace doesn’t mean pretending sin doesn’t exist. Grace gives us strength to face it, confess it, and let God cleanse it.
Verse 3–5: A Hard Decision — Discipline Out of Love
Paul says, “Even though I am not physically present, I am with you in spirit, and I have already passed judgment on the one who did this.”
Now, at first, that sounds harsh, right?
But look closer — this isn’t revenge; it’s restoration.
Paul says, “When you are assembled in the name of the Lord Jesus, and I am with you in spirit, deliver this man to Satan for the destruction of the flesh, that his spirit may be saved in the day of the Lord.”
That sounds intense, but it means removing him from the protection of the church community, letting him face the consequences of his choices — so that his spirit may be saved.
The goal wasn’t to destroy him. It was to wake him up.
Sometimes love means saying, “You can’t stay here if you’re going to keep living that way.”
Not out of hate, but because holiness matters.
And sometimes, people only see clearly when they hit the wall of consequence.
It’s not about kicking someone out of heaven — it’s about calling them back to it.
Verse 6–8: A Little Yeast Affects the Whole Batch
Paul uses an old image — leaven, or yeast.
“Your boasting is not good. Don’t you know that a little leaven leavens the whole lump?”
He’s saying, sin spreads quietly.
If the church ignores one sin, soon others will think, “Well, that’s okay too.”
Holiness isn’t about rules — it’s about health.
Sin is like infection. If you don’t treat it, it spreads.
Paul connects it to Passover:
“For Christ, our Passover Lamb, has been sacrificed. Therefore let us keep the feast, not with the old leaven of malice and wickedness, but with sincerity and truth.”
What a beautiful image — Jesus as the Passover Lamb, sacrificed so that death would pass over us.
And Paul says, “Let’s live like people who’ve been rescued — clean, sincere, truthful.”
The feast is our life in Christ — not perfect, but purified by His blood.
Verse 9–11: Who We Should and Shouldn’t Avoid
Paul clears up something that might confuse people.
He says, “I wrote to you not to associate with sexually immoral people.”
But then he explains — not meaning unbelievers, because then you’d have to leave the world entirely!
He means those who claim to be believers but live in open, unrepentant sin — those who talk about Jesus but mock holiness.
He lists: “Anyone who calls himself a brother but is sexually immoral, greedy, an idolater, a slanderer, a drunkard, or swindler — do not even eat with such a one.”
That’s strong language.
But Paul’s making a distinction between the struggling and the stubborn.
We all stumble — we’re all sinners saved by grace.
But when someone lives in sin proudly, refusing correction, and still claims to represent Christ — that’s what Paul is warning against.
Because the church is supposed to be a light, not a mirror of the world.
Verse 12–13: Judgment Within the Family of Faith
Paul ends the chapter saying,
“What business is it of mine to judge those outside the church? Are you not to judge those inside?”
That flips the modern mindset upside down.
We often do the opposite — we harshly judge outsiders who don’t know Christ and ignore sin inside the church because we’re afraid to “offend.”
But Paul says, “No — let God handle those outside. You take care of your family.”
And he quotes the Old Testament:
“Expel the wicked person from among you.”
Again, the goal is not punishment. It’s protection — for the person, for the church, for the witness of Christ.
It’s like cleaning a wound — it hurts, but if you don’t, infection spreads.
Reflection – The Pain and Beauty of Holiness
This chapter shows us something that modern believers often avoid — that holiness still matters.
It’s not old-fashioned. It’s not “religious.” It’s beautiful.
The Corinthians had confused grace with permission.
They thought love meant never confronting sin.
But true love cares too much to stay silent.
If a friend is walking toward a cliff, you don’t smile and say, “Do what feels right.”
You grab them — even if they’re angry — because you love them too much to let them fall.
That’s Paul’s heart here.
He’s not a legalist. He’s a shepherd.
And sometimes shepherds have to chase down wandering sheep — even the ones that bite back.
The Church’s Responsibility
This chapter is a reminder that the church isn’t supposed to blend in with culture.
We’re supposed to be salt and light.
And salt only preserves when it’s different.
Paul isn’t telling us to be judgmental or self-righteous. He’s saying, “Be honest about sin. Deal with it in love.”
You can’t heal what you won’t name.
And when a church becomes proud of its tolerance instead of its truth — something’s deeply wrong.
Real love always tells the truth, even when it trembles doing it.
Restoration, Not Rejection
Here’s something important — later, in 2 Corinthians, Paul writes about this same man.
And guess what? He repented.
Paul then tells the church, “Now forgive him, comfort him, reaffirm your love for him.”
That’s the full circle of grace.
Discipline, repentance, restoration.
God’s mercy always waits at the end of correction.
So even in this hard chapter, grace wins.
Because the point was never to throw someone away — it was to bring them home again.
Modern Lessons
Maybe today we don’t have the exact same scandal, but we do have sin that sneaks into our hearts — pride, greed, gossip, lust, unforgiveness.
And maybe we’ve grown comfortable with them because “everybody does it.”
But Paul’s voice still echoes:
A little leaven leavens the whole lump.
Don’t ignore the small compromises.
Don’t call it freedom when it’s really bondage.
Don’t dress sin in soft words.
God’s love is gentle, but it’s also holy.
And when He disciplines us, it’s not rejection — it’s rescue.
Closing Thoughts
1 Corinthians 5 is uncomfortable — but necessary.
It’s the kind of chapter that makes you squirm, but also reminds you how serious and how beautiful grace really is.
Because if God didn’t care, He wouldn’t correct us.
If He didn’t love us, He’d let us stay lost.
So maybe holiness isn’t about perfection — it’s about belonging.
Belonging so deeply to Christ that we want nothing to come between us and Him.
Paul wasn’t protecting a reputation — he was protecting a relationship.
The church belongs to Jesus.
And when sin creeps in, it clouds the reflection of His face in us.
So we let Him cleanse us — again and again — because He’s worth it.
And maybe the quiet takeaway is this:
Love doesn’t look away.
Love looks right at the mess, and still says, “You’re mine — but we have to deal with this.”
That’s the love of a Father.
That’s the holiness of grace.
That’s the heartbeat of 1 Corinthians 5.
