The letter was most probably written while Paul was in Corinth, probably while he was staying in the house of Gaius, and transcribed by Tertius, his amanuensis. There are a number of reasons why Corinth is considered most plausible. Paul was about to travel to Jerusalem on writing the letter, which matches Acts[Acts 20:3] where it is reported that Paul stayed for three months in Greece. This probably implies Corinth as it was the location of Paul’s greatest missionary success in Greece. Additionally, Phoebe was a deacon of the church in Cenchreae, a port to the east of Corinth, and would have been able to convey the letter to Rome after passing through Corinth and taking a ship from Corinth’s west port. Erastus, mentioned in Romans 16:23, also lived in Corinth, being the city’s commissioner for public works and city treasurer at various times, again indicating that the letter was written in Corinth.
