Who Wrote This Book:  Apostle Paul

Date of Writing:  Paul wrote 1 Corinthians from the city of Ephesus around 55 A.D. in the Roman province of Asia (16:8, 19) sometime before the final day of Pentecost (16:8; cf. Lev. 23:11, 15), and therefore in the spring.

Written To:  The letter was written to the Corinthians.

Why It Was Written:  Corinth sat on the isthmus connecting the Greek mainland with the Peloponnesian peninsula.  This location made it a flourishing crossroads for sea traffic between the Aegean region and the western Mediterranean.  It was a place where many cultures and religions mingled.  Since it was a Roman colony, Roman law and customs were important, particularly among the upper classes, but “many ‘gods’ and many ‘lords’” found a home in Corinth (8:5).  The worship of these gods was fully integrated into governmental affairs, civic festivals, trade guilds, and social clubs, and everyday life in general.  Corinth was also a destination for traveling professional orators who charged a fee for attendance at their entertaining rhetorical displays and advised people on how to advance socially.

Into this milieu Paul brought the gospel of Jesus Christ, and soon a church was established.  He was aided in his work by two new-found friends from Rome, Priscilla and Aquila, who, like Paul, were displaced Jews and tentmakers by trade (Acts 18:1–4, 18–19, 24–28; Rom. 16:3; 2 Tim. 4:19).  Paul, Priscilla, and Aquila spent 18 months in Corinth in the early 50s and then, after a brief trip to Judea and Syria, Paul traveled to Ephesus.  Priscilla and Aquila were already there (Acts 18:19; 1 Cor. 16:19) and, by the time Paul arrived, they had already met the skillful Christian apologist Apollos, who had also been in Corinth (Acts 18:24–19:1; 1 Cor. 1:12; 3:4–6, 22; 4:6; 16:12).

Paul settled in Ephesus for three years (Acts 20:31) and at some point wrote to the Corinthians the otherwise unknown letter that he mentions in 1 Corinthians 5:9.  It is not known what prompted the letter but it dealt with sexual immorality, a persistent problem for the Corinthian church (5:1–13; 6:12–20).  Sometime later, Paul received an oral report indicating that the Corinthians had not only misunderstood his first letter (5:10) but were plagued with serious problems of division, sexual immorality, and social snobbery (1:10; 5:1; 11:18).  Around the same time, a letter arrived from the Corinthians that displayed considerable theological confusion about marriage, divorce, and participation in pagan religions, order within corporate worship, and the bodily resurrection of Christians (7:1; 8:1; 12:1; 15:12, 35).

In response to these troubling developments, Paul felt compelled to write a substantial letter to Corinth, making the case that much of their conduct was out of step with the gospel.  At the root of their disunity lay an arrogance (3:21; 4:6, 8, 18–19; 5:2, 6) that was incompatible with God's free gifts to them in Christ: wisdom, righteousness, sanctification, and redemption (1:30; 4:7).  In addition, a self-centered insistence on their own rights (6:12; 8:9; 9:12; 10:23) at the expense of the weak (8:10; 11:22) and marginalized (14:16, 23) revealed that their own social advancement rather than the gospel's advancement was their top priority.

At the root of much of the immorality and idolatry in Corinth, moreover, lay a lack of appreciation for the holiness that God requires of his people.  Though the particulars of the Mosaic law were no longer to define the boundaries for God's people (7:19), the law's underlying theme that God's people were to be “set apart”—a people marked off from their culture—remained in place (5:1–2, 13; 7:19; 10:1–5).  In addition, the dwelling of God's Spirit within each believer (6:19) and the new unity that believers have with the resurrected, living Christ (6:14–17; 15:30–34) implied that the Corinthians needed to make a clean break from the moral impurity of their culture.

Despite the often stern tone of the letter (4:18–21; 5:2; 11:17, 22; 15:36), Paul was thankful to God for the Corinthians (1:8) and felt a deep personal affection for them (16:24).  Because of this love, and for the purpose of God's glory (10:31), Paul wanted the Corinthians to become a well-constructed dwelling place for God's Spirit (3:12, 16) and to be “guiltless in the day of our Lord Jesus Christ” (1:8).
