First Corinthians is one of the most personal and practical letters in the New Testament—a pastor's urgent response to a young church struggling to live out the gospel amid the pressures of a proud and permissive city.
Author, Date, and Audience
The letter's authorship is virtually undisputed: the apostle Paul names himself as the writer (1:1), and both internal evidence and the testimony of the early church confirm it. Writing alongside Sosthenes, Paul almost certainly composed the letter from Ephesus during his lengthy ministry there (see 16:8), most likely around A.D. 53–55. His audience was the church he had planted in Corinth (Acts 18), a bustling Roman commercial hub notorious for its wealth, diversity, and moral laxity. The congregation was largely Gentile, socially varied, and richly gifted—yet spiritually immature.
Paul wrote in response to troubling reports brought to him "by Chloe's people" (1:11) and to a list of questions the Corinthians had sent him (7:1). The church was fracturing into factions, tolerating scandalous sin, suing one another, abusing the Lord's Supper, and quarreling over spiritual gifts. His purpose was both corrective and constructive: to heal divisions, to confront sin, and to teach this gifted but worldly church what it means to be the body of Christ shaped by the cross.
Major Themes
At the heart of the letter stands "the word of the cross" (1:18). Against a culture that prized eloquence, status, and human wisdom, Paul insists that God's wisdom and power are revealed in a crucified Messiah. From this center flow the letter's great concerns: unity over party spirit; holiness in matters of sexuality and marriage; love as the governing principle of Christian freedom and worship; the orderly, edifying use of spiritual gifts; and the bodily resurrection of believers grounded in the resurrection of Christ. The famous hymn to love in chapter 13 and the resurrection chapter (15) belong among the most treasured passages in all of Scripture.
Structure
The letter falls naturally into clear movements:
- 1:1–9 — Greeting and thanksgiving
- 1:10–4:21 — Divisions in the church and the wisdom of the cross
- 5:1–6:20 — Moral disorder: immorality, lawsuits, and the sanctity of the body
- 7:1–11:1 — Answers on marriage, singleness, and Christian freedom
- 11:2–14:40 — Public worship: the Lord's Supper and spiritual gifts
- 15:1–58 — The resurrection of the dead
- 16:1–24 — The collection, travel plans, and final greetings
Christ and the Story of Redemption
For all its practical counsel, 1 Corinthians is relentlessly Christ-centered. Paul resolves to know "nothing... except Jesus Christ and him crucified" (2:2), and he names Christ as "our Passover lamb" (5:7), the true exodus deliverance to which Israel's redemption pointed. Christ is "the Rock" who accompanied God's people in the wilderness (10:4) and the second Adam in whom a new humanity is raised to life (15:22, 45). The risen Christ stands as the "firstfruits" of the great harvest of resurrection, the guarantee that death itself will be swallowed up in victory (15:20–57).
In this way the letter binds the whole sweep of redemption together. The cross that the world counts as foolishness is the very wisdom and power of God, fulfilling the promises of the Old Testament and securing the church's future glory. Until Christ returns and hands the kingdom to the Father (15:24–28), the Corinthians—and every church since—are called to live as those who proclaim the Lord's death "until he comes" (11:26), built up in love as the one body of the crucified and risen Lord.
