CHOREPISCOPUS, an officer in the ancient church, about whose function the learned are extremely divided. The word comes from choros, a region, or little country, and episcopos, a bishop, or over-seeer.
The chorepiscopi were suffragan or local bishops, holding a middle rank between bishops and presbyters, and delegated to exercise episcopal jurisdiction within certain districts, when the boundaries of particular churches, over which separate bishops presided, were considerably enlarged. It is not certain when this office was first introduced: some trace it to the close of
the first century; others tell us, that chorepiscopi were not known in the east till the beginning of the fourth century; and in the west about the year 439. They ceased both in the east and west in the tenth century.
CHOREPISCOPUS is also the name of a dignity still subsisting in some cathedrals, particularly in Germany; signifying the same with chori episcopus, or "bishop of the choir." The word, in this sense, does not come from choros, place, but choros, choir, &c. In the church of Cologne, &c. the first chanter is called chorepiscopus.
