1 Corinthians

“For the word of the cross is folly to those who are perishing, but to us who are being saved it is the power of God.” — 1 Corinthians 1:18

Overview

Background and Context

Corinth was one of the most important cities in the Roman world — a rebuilt colony commanding trade routes between the Aegean and the Adriatic, home to people from across the Mediterranean, famous for its wealth, its religious diversity, its culture of competitive rhetoric, and its sexual permissiveness (the verb “to Corinthianize” had entered Greek as a byword for immorality). Paul spent eighteen months there on his second missionary journey, around AD 50-52, establishing a community that cut across social lines: slaves and freedmen, artisans and wealthy householders, Jews and Gentiles.

After leaving Corinth, Paul received troubling news from two sources. Members of “Chloe’s household” reported factions forming around different teachers. Then the Corinthians sent a letter asking Paul’s opinion on a list of practical questions. First Corinthians is Paul’s response to both, and the letter’s structure roughly follows the two sources: chapters 1–6 address the oral reports, chapters 7–16 work through the questions (each introduced by “now concerning…”).

The church’s problems are not those of ignorance or poverty. They are the problems of a gifted, sophisticated urban community that has absorbed more of Corinth’s ambient culture than it realizes. They prize eloquence, wisdom, status, and freedom — all real goods — but have arranged them around the self rather than the crucified Christ. Paul’s pastoral strategy is not merely to give rules but to reframe: every particular problem he addresses, he anchors to the gospel’s core logic.

Divisions and Wisdom (Ch 1–4)

Paul opens by naming the problem directly: there are quarrels among them. People are claiming allegiance to different teachers — “I follow Paul,” “I follow Apollos,” “I follow Cephas” — turning the church into a competition between personalities. Paul responds with a theological argument rather than a political one: the cross makes all human wisdom and status irrelevant. God chose what is foolish in the world to shame the wise; the word of the cross is, by the world’s standards, an absurdity. Any boasting must be in the Lord alone.

This is not anti-intellectualism. Paul insists that he does speak wisdom among the mature — but it is God’s wisdom, hidden and revealed through the Spirit. The Corinthians, however, are still “infants in Christ,” feeding on milk rather than solid food, because they are still living by the world’s categories of status and division. The teachers — Paul, Apollos, Cephas — are merely servants, different workers in the same field, with God as the one who gives growth. It is absurd to build factions around them.

Paul closes this section with one of his sharpest passages: some of the Corinthians have become “puffed up” as if Paul were not coming back. He is coming, and he will find out not the talk of these arrogant people but their power. “The kingdom of God does not consist in talk but in power.” The whole argument of chapters 1–4 is a sustained demolition of the cultural prestige system that the Corinthians have imported into the church — and a call to center everything on the crucified, risen Christ.

Sexuality and Marriage (Ch 5–7)

The oral reports have included a case of sexual immorality that shocks even pagan Corinth: a man is sleeping with his father’s wife. The church, apparently, is proud rather than grieved — perhaps viewing this as an expression of Christian freedom. Paul is unambiguous: this man must be removed from the community, handed over to Satan for the destruction of the flesh so that his spirit may be saved. He also warns against judging outsiders — the church has no jurisdiction there — but it does have a responsibility for its own members’ conduct.

He addresses lawsuits among believers: it is already a defeat to be taking one another to court before unbelievers. Then a more extended treatment of sexual ethics: the body matters to God. It is a temple of the Holy Spirit, bought with a price. “Flee from sexual immorality” — the only sin Paul calls his readers to flee rather than resist — is not prudishness but a recognition that sexual union is uniquely body-constituting in a way that other sins are not.

Chapter 7 turns to the Corinthians’ written question about marriage. Paul’s answer is carefully nuanced: marriage is good, and within it husband and wife have mutual sexual obligations. Singleness is also good — Paul himself is single and commends it as allowing undivided devotion to the Lord — but it is a gift, not a requirement. Those who are married should stay married; those whose unbelieving spouses leave may let them go. Paul is not legislating one superior way of life but offering pastoral wisdom sensitive to different callings.

Freedom and Conscience (Ch 8–10)

The Corinthians asked about food offered to idols — much of the meat sold in Corinth had passed through pagan temple rituals. Paul’s answer is three chapters long, because the question opens onto a larger issue: how does Christian freedom work when it affects others?

The theologically confident Corinthian argument is correct as far as it goes: idols are nothing, there is one God, food is food. But knowledge alone puffs up; love builds up. If a weaker believer sees you eating in an idol’s temple and is led to act against their conscience, your exercise of knowledge has destroyed a brother for whom Christ died. Paul introduces himself as an exhibit: he has apostolic rights — to be supported financially, to travel with a wife — but he has waived them all to avoid putting any obstacle in the gospel’s way. He runs to win, disciplines his body, makes himself a slave to all in order to win some.

Chapter 10 grounds the warning in Israel’s history: Israel in the wilderness had every spiritual advantage — cloud, sea, manna, spiritual drink — and still fell into idolatry and immorality, which became types and warnings for the church. The point is not that the Corinthians must avoid all pagan contact — they would have to leave the world — but that they must not test the Lord by treating idolatry casually. The practical rule is: eat what is sold in the market without asking questions; if a host announces that meat was offered to idols and a weaker conscience is at stake, abstain for their sake. “Whatever you do, do all to the glory of God.”

Worship in Order (Ch 11–14)

Paul turns to problems in gathered worship, and the issues are serious. There are divisions in how the Lord’s Supper is being celebrated: the wealthier members eat their own food and drink freely while the poorer members go hungry. Paul traces the eucharist back to Jesus’s own institution at the Last Supper and says plainly: eating and drinking in an unworthy manner — treating the ordinary divisions of the world as if they belong at the Lord’s table — is to be guilty of profaning the body and blood of the Lord. Examine yourselves before eating. Wait for one another.

Chapters 12–14 address spiritual gifts (charismata) at length. The Corinthians apparently prize the more spectacular gifts, especially speaking in tongues, and disorder has resulted. Paul responds on several levels. First, the Spirit gives diverse gifts to different members — no gift is universal, no gift is superior in itself — and the community is like a body with many members, none of which can say it doesn’t need the others. Second, the purpose of gifts is not personal edification but the building up of the whole community. Tongues without interpretation edifies only the speaker; prophecy edifies the whole congregation. Paul himself speaks in tongues but would rather speak five intelligible words in church than ten thousand in a tongue. Worship must be orderly and comprehensible, especially for outsiders who may be present.

The Love Chapter (Ch 13)

Nestled between the two chapters on spiritual gifts, chapter 13 is Paul’s most celebrated passage and one of the most read texts in Western literature. He does not present love as a feeling or a virtue but as the necessary context in which every gift operates. Tongues without love is noise; prophecy without love is nothing; giving everything to the poor without love profits nothing. Then the character of love itself: patient, kind, not envious or boastful or arrogant or rude, not insisting on its own way, not irritable or resentful, not rejoicing in wrongdoing but rejoicing with the truth.

Love is not presented as a gift among other gifts but as the environment in which gifts function rightly. Gifts will pass away — tongues will cease, knowledge will pass away — but love never ends. Now we know in part and prophesy in part; then we shall know fully, even as we are fully known. The three things that remain are faith, hope, and love; the greatest is love. The chapter does not stand alone but is Paul’s answer to the Corinthians’ misuse of gifts: the problem is not that you have the wrong gifts but that you are exercising them without love.

The Resurrection (Ch 15)

Chapter 15 is Paul’s most extended theological argument in any letter — a sustained defense of the bodily resurrection of Jesus and of believers. He opens with what he calls the gospel in summary: Christ died for our sins according to the scriptures, he was buried, he was raised on the third day according to the scriptures, and he appeared — to Cephas, then to the twelve, then to more than five hundred, then to James, then to all the apostles, then to Paul himself as to one untimely born.

Some in Corinth were saying there is no resurrection of the dead. Paul takes this with absolute seriousness: if the dead are not raised, then Christ has not been raised; if Christ has not been raised, the preaching is futile and faith is futile, and believers are still in their sins. The entire gospel stands or falls with the resurrection. But Christ has in fact been raised — the firstfruits of those who have fallen asleep. As in Adam all die, so in Christ shall all be made alive.

Paul then addresses the natural question: in what kind of body do the dead rise? He uses the analogy of a seed: you do not plant the body that will be, but a bare seed. The resurrection body is a spiritual body — not immaterial but transformed, imperishable, glorious. The last enemy to be destroyed is death itself. The chapter closes with one of Paul’s most triumphant passages: “Death is swallowed up in victory. O death, where is your victory? O death, where is your sting? The sting of death is sin, and the power of sin is the law. But thanks be to God, who gives us the victory through our Lord Jesus Christ.”

Final Instructions (Ch 16)

The last chapter returns to practical matters. Paul gives instructions for the collection he is gathering from Gentile churches for the poor in Jerusalem — each person is to set aside money on the first day of every week, proportional to what they have. He describes his travel plans and commends Timothy and others. The closing greetings and exhortations are characteristically warm and pointed: “Be watchful, stand firm in the faith, act like men, be strong. Let all that you do be done in love.” He ends with an Aramaic prayer that shows the letter’s Jewish roots: Maranatha — Our Lord, come.

Key Themes

The Cross as the Center of Everything — Paul returns obsessively to the cross throughout this letter. It is “the word of the cross” that reorders every human category of wisdom, power, and status. The Corinthians’ problems — their divisions, their sexual ethics, their misuse of gifts — all trace back to a failure to let the cross reshape their values. Paul’s summary of his own ministry in chapter 2 is strikingly simple: “I decided to know nothing among you except Jesus Christ and him crucified.”

Unity in the Body of Christ — The church is not a collection of individuals exercising their spiritual gifts in parallel. It is a body, and the parts depend on one another. Division — whether around personalities, social class, or gift-ranking — contradicts the very nature of what the church is. Paul’s ecclesiology is not organizational but organic: the Spirit constitutes the body, and love is the life that flows through it.

Freedom and Responsibility — One of the letter’s most sustained tensions is between genuine Christian freedom and the responsibilities that freedom creates. The Corinthians know they are free in Christ; Paul’s argument is that freedom exercised without love is not actually freedom but a new form of self-centeredness. The mature exercise of freedom takes the other person into account.

The Resurrection as Foundation — Chapter 15 makes explicit what the whole letter assumes: the resurrection of Christ is not a peripheral doctrine but the ground of everything. If Jesus was not raised, nothing Paul says about spiritual gifts, love, marriage, or community ethics has any ultimate weight. The resurrection is the reality that makes the Christian life coherent.

Love as the Greatest Gift — Chapter 13 crowns the letter’s argument. Against a church that prizes spectacular gifts, Paul insists that the measure of spiritual maturity is not power or knowledge or rhetorical brilliance but the patient, self-giving love that mirrors God’s own character. It is the most excellent way not because it is the most emotionally satisfying but because it is the only way that actually builds anything that will last.
