Cathedra

A cathedra is the raised throne of a bishop in the early Christian basilica.[1] When used with this meaning, it may also be called the bishop's throne.[citation needed] With time, the related term cathedral became synonymous with the "seat", or principal church, of a bishopric.[1]

The word in modern languages derives from a normal Greek word καθέδρα [kathédra], meaning "seat", with no special religious connotations[citation needed], and the Latin cathedra, specifically a chair with arms.[citation needed]

It is a symbol of the bishop's teaching authority in the Catholic Church, the Orthodox Church, and the Anglican Communion churches.[citation needed]
