Quartus

Quartus (Latin meaning fourth) was a Christian at Corinth who sent greetings in Paul's letter to the Romans (Romans 16:23), described as "a brother" — indicating he was a member of the church known to Paul's Roman recipients. He is mentioned alongside Erastus the city treasurer of Corinth in the closing greetings of Romans, suggesting he was part of the Corinthian congregation. No other details about Quartus are preserved in Scripture. His Latin name suggests he may have been of Roman background, and his place in the greeting list indicates he was sufficiently well-connected to the Roman church to warrant a personal mention.
