The city of Corinth was located at an important crossroads in Greece. Situated on the narrow strip of land between northern and southern Greece, Corinth controlled north-south overland traffic. Sea traffic moving east and west also made use of the narrow isthmus to avoid the long journey around the southern end of Greece. Small boats could be hauled across the isthmus, while larger boats sent their cargo across. Corinth was a major cultural and religious center. Paul came to Corinth after establishing congregations in Philippi and Thessalonica. He supported himself by making tents along with Aquila and Priscilla. A number of people in Corinth accepted Paul's message, and Paul remained there for eighteen months (Acts 18:1-17). When Paul left Corinth, Priscilla and Aquila went with him. At a later time, Paul wrote a number of letters to the congregation at Corinth. He visited Corinth several times during his ministry.
