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"), which itself was derived from minus ("less"). With respect to ecclesiastical address, many ministers are styled as "The Reverend"; however, some use "Pastor" or "Father" as a title.
