What does Romans 16:23 mean?
Paul sends greetings to the Christians in Rome from three more of the men with him in Corinth. Three men named Gaius are mentioned in the New Testament (Acts 20:4; 3 John 1; 1 Corinthians 1:14). This one is most probably the same one mentioned by Paul in 1 Corinthians 1:14 as a man he baptized while in Corinth. Paul is apparently staying at Gaius's house. He describes Gaius as a host to the entire church, perhaps meaning that his regular practice is to host Christians from out of town or that the church in Corinth, or some part of it, meets in Gaius's home.Christian converts in the early church were found at all levels of social and economic status in society. Paul describes a man named Erastus as a city official. Depending on how the term oikonomos is interpreted, he was the city treasurer, a director of public works, or some civil officer. Some have suggested that an inscription found in the ruins of ancient Corinth in 1929, mentioning a man named Erastus as an "aedile," is this same man.
Paul sends his final greeting from a fellow believer named Quartus, a man not mentioned anywhere else in the New Testament.
