Meaning in one sentence
Paul rejoices in his weakness when it means the Corinthians are strong. He prays for their katartisis, their restoration, like setting a broken bone.
Context
Paul is wrapping up his second letter to the Corinthian church. He has spent much of it defending his authority and calling them to turn from sin. In verse 7 he prays they do no evil, not so he can look approved but so they can do what is right. Verse 8 says he can only act for the truth. Then comes verse 9. Paul is not being sarcastic. He genuinely rejoices when they are strong and he appears weak, because their spiritual health matters more than his reputation. He also prays for their perfection, a word that carries the image of a dislocated bone being set back in place. That is what he wants for them: healing and proper order.
Key Words
Two Greek words stand out in this verse. The word for weak, astheneō, means to be without strength, powerless. Paul uses it often to describe his own condition, but he does not resent it. He rejoices in it when it means the Corinthians are dunatos, mighty, strong in Christian virtue.
The second key word is katartisis, translated as perfection. This word appears only once in the entire New Testament. It literally means setting a bone, reducing a fracture, or putting a dislocated joint back in its socket. Paul prays for that kind of restoration for the Corinthian church. They had been torn apart by factions and sin. He wants them healed and reunited. Christian maturity is not about flawless performance. It is about being put back together, fitted into proper place.
How Christians Read This Verse
Christians across traditions have found deep meaning in this word. Methodist commentator Adam Clarke noted that katartisis means reducing a dislocated limb. For Clarke, Paul wanted the Corinthians joined together in love. John Calvin, from the Reformed tradition, said the perfection consists in a fit proportion and sound condition of all the members. The Cambridge Bible, representing Anglican scholarship, suggested the image is like fitting pieces of a mosaic together. Baptist commentator John Gill also used the image of setting bones that are out of joint. All see in this verse a vision of restoration, not merely individual holiness but a community healed and in order.
A common misunderstanding
Some read perfection here as sinless moral flawlessness, as if Paul expects the Corinthians to become completely without sin before Christ returns. In fact, the Greek word katartisis points to something different: the restoration of something broken, like a dislocated bone set back in place. Paul is praying for healing and unity, not absolute sinlessness. The same verb appears in verse 11: Be perfected, meaning to be restored to proper order.
Living This Out
It is easier to want to be strong ourselves than to rejoice when someone else is strong. Yet Paul models a different way. He finds his joy not in his own reputation but in the spiritual health of those he serves. This week, you might face a situation where a friend, colleague, or family member succeeds in something you have struggled with. Can you celebrate that with genuine joy?
Paul also prays for the Corinthians katartisis. You can pray the same for your own church community. Ask God to set what is dislocated back in place, to heal divisions and realign relationships.
Main takeaway: Paul rejoices in his own weakness when it means others are strong, and his deepest prayer is for their complete restoration.
For Families
For ages 5, 8
Paul was happy even when he felt weak, because the people he loved were strong. He prayed that they would be fixed up, like when a doctor sets a broken bone so it can heal right.
For ages 9, 12
Paul had a surprising way of thinking. He didn't care if he looked weak or unimportant, as long as the Christians in Corinth were growing strong. And when he prayed for their perfection, he wasn't asking them to be perfect like never making mistakes. He was using a word that meant being put back together. The Corinthian church was like a body with bones out of place, there were arguments and divisions. Paul prayed for healing and unity. You can pray for that in your own friendships and family too.
