In Christianity, a minister is a person authorised by a church or other religious organization to perform functions such as teaching of beliefs; leading services such as weddings, baptisms or funerals; or otherwise providing spiritual guidance to the community. The term is taken from Latin minister ("servant", "attendant"). In some church traditions the term is usually used for people who have been ordained, but in other traditions it can also be used for non-ordained people who have a pastoral or liturgical ministry. In Catholic, Orthodox (Eastern and Oriental), Anglican and Lutheran churches, the concept of a priesthood is emphasized. In other denominations such as Baptist, Methodist and Calvinist churches (Congregationalist and Presbyterian), the term "minister" usually refers to a member of the ordained clergy who leads a congregation or participates in a role in a parachurch ministry; such a person may serve as an elder (presbyter), pastor, preacher, bishop, or chaplain. With respect to ecclesiastical address, many ministers are styled as "The Reverend"; however, some use "Pastor" or "Father" as a title. Roles and duties The Church of England defines the ministry of priests as follows: Ministers may perform some or all of the following duties: assist in co-ordinating volunteers and church community groups assist in any general administrative service conduct marriage ceremonies, funerals and memorial services, participate in the ordination of other clergy, and confirming young people as members of a local church encourage local church endeavors engage in welfare and community services activities of communities establish new local churches keep records as required by civil or church law plan and conduct services of public worship preach pray and encourage others to be theocentric (that is, God-focused) preside over sacraments (also called ordinances) of the church.
