An essay on ecclesiastical authority in which the pretence of an independent power in the church, to a divine right in the election of bishops; to the invalidity of lay deprivations; to the inseparable relation of a bishop to his see; to an obligation of continuing communion with the deprived bishops; and several other things relating to the nonjurors separation from our church, are particulary and impartially examined. By John Turner, D.D. Vicar of Greenwich, and chaplain to His Royal Highness the Prince.
