Clergy
Clergy are some of the formal leaders within certain religions. The roles and functions of clergy vary in different religious traditions but these usually involve presiding over specific rituals and teaching their religion's doctrines and practices. Some of the terms used for individual clergy are cleric, clergyman, clergywoman, clergyperson, and churchman.
In Christianity the specific names and roles of clergy vary by denomination and there is a wide range of formal and informal clergy positions, including deacons, priests, bishops, preachers, pastors, and ministers. In Islam, a religious leader is often known formally or informally as an imam, mufti, mullah or ayatollah. In Jewish tradition, a religious leader is often a rabbi or hazzan (cantor).
Etymology
The term ultimately comes from the Greek "κλῆρος" - klēros, "a lot", "that which is assigned by lot" (allotment) or metaphorically, "inheritance". Within Christianity, especially in Eastern Christianity and formerly in Western Roman Catholicism, the term cleric refers to any individual who has been ordained, including deacons, priests, and bishops. In Latin Roman Catholicism, the tonsure was a prerequisite for receiving any of the minor orders or major orders before the tonsure, minor orders, and the subdiaconate were abolished following the Second Vatican Council. Now, the clerical state is tied to reception of the diaconate.Minor Orders are still given in the Eastern Catholic Churches, and those who receive those orders are 'minor clerics.'
