Oikonomos (Greek: οἰκονόμος, from οἰκο- 'house' and -νόμος 'rule, law'), Latinized œconomus, oeconomus, or economos, was an Ancient Greek word meaning "household manager." In Byzantine times, the term was used as a title of a manager or treasurer of an organization.
It is a title of honor awarded to priests in the Eastern Orthodox Church.[1] It is also a title in the Roman Catholic Church.[2] In Canon 494 of the 1983 Code of Canon Law, an œconomus is the diocesan finance officer.
