PriestA priest is a religious leader authorized to perform the sacred rituals of a religion, especially as a mediatory agent between humans and one or more deities. They also have the authority or power to administer religious rites; in particular, rites of sacrifice to, and propitiation of, a deity or deities. Their office or position is the 'priesthood', a term which also may apply to such persons collectively.
DeaconA deacon is a member of the diaconate, an office in Christian churches that is generally associated with service of some kind, but which varies among theological and denominational traditions. Major Christian churches, such as the Catholic Church, the Oriental Orthodox Churches, the Eastern Orthodox Church, the Scandinavian Lutheran Churches, the Methodist Churches, the Anglican Communion, and the Free Church of England, view the diaconate as an order of ministry.
ClergyClergy are formal leaders within established religions. Their roles and functions vary in different religious traditions, but usually involve presiding over specific rituals and teaching their religion's doctrines and practices. Some of the terms used for individual clergy are clergyman, clergywoman, clergyperson, churchman, ecclesiastic, and cleric, while clerk in holy orders has a long history but is rarely used.
MonasteryA monastery is a building or complex of buildings comprising the domestic quarters and workplaces of monastics, monks or nuns, whether living in communities or alone (hermits). A monastery generally includes a place reserved for prayer which may be a chapel, church, or temple, and may also serve as an oratory, or in the case of communities anything from a single building housing only one senior and two or three junior monks or nuns, to vast complexes and estates housing tens or hundreds.
DioceseIn church governance, a diocese ˈdaisis or bishopric is the ecclesiastical district under the jurisdiction of a bishop. Bishops and civil government In the later organization of the Roman Empire, the increasingly subdivided provinces were administratively associated in a larger unit, the diocese (Latin dioecesis, from the Greek term διοίκησις, meaning "administration"). Christianity was given legal status in 313 with the Edict of Milan. Churches began to organize themselves into dioceses based on the civil dioceses, not on the larger regional imperial districts.
PresbyterPresbyter (ˈprɛzbɪtər) is an honorific title for Christian clergy. The word derives from the Greek presbyteros, which means elder or senior, although many in the Christian antiquity would understand presbyteros to refer to the bishop functioning as overseer. The word presbyter is used many times in the New Testament. In modern Catholic, Orthodox and Anglican usage, presbyter is distinct from bishop and (in English) is synonymous with priest.
