Corinth means in the bible: The capital of the Roman province Achaia. The magnificent location it had on the Peloponnesus-Greek mainland isthmus, with a harbor at both the eastern and west sides, was a highlight of its existence. The Roman conquest of 146 B.C. almost destroyed it, but Julius Caesar rebuilt it a hundred year later. Paul spent a year here and six months Acts 18.1-18 during his second missionary trip. Apollos visited it shortly after Paul’s departure. The two epistles of the Corinthians reveal that there was a division in the Church and that Judaizing was active. The famous Isthmian Games were located near here, where Paul takes the striking imagery from 1 Cor. 9:24-27.
