Coadjutor bishop

A coadjutor bishop (or bishop coadjutor) is a bishop in the Catholic, Anglican, and (historically) Eastern Orthodox churches whose main role is to assist the diocesan bishop in the administration of the diocese. The coadjutor (literally, "co-assister" in Latin) is a bishop himself, although he is also appointed as vicar general. The coadjutor bishop is, however, given authority beyond that ordinarily given to the vicar general, making him co-head of the diocese in all but ceremonial precedence. In modern times, the coadjutor automatically succeeds the diocesan bishop upon the latter's retirement, removal, or death.
