Erastus of Paneas was a steward in Corinth; (oikonomos), a political office of high status. It is defined as “the manager of household affairs, or, in this context, treasurer.”

23 Gaius, my host and the host of the whole church, greets you. Erastus, the treasurer of the city, greets you, and Quartus, a brother.
— Rom. 16:23
