A bishop who assists the diocesan bishop by providing additional episcopal services. An assistant bishop is appointed by the diocesan bishop, with the approval of the Standing Committee of the diocese. The assistant bishop must already be exercising episcopal jurisdiction as a diocesan bishop, or serving as a suffragan bishop, or a qualified bishop who has previously resigned all previous responsibilities, or a qualified bishop of a church in communion with the Episcopal Church. The assistant bishop serves under the direction of the diocesan bishop, and may not serve beyond the termination of the appointing bishop's jurisdiction. In the nineteenth century, bishops coadjutor in the Episcopal Church were known as assistant bishops.
