ChaplainA chaplain is, traditionally, a cleric (such as a minister, priest, pastor, rabbi, purohit, or imam), or a lay representative of a religious tradition, attached to a secular institution (such as a hospital, prison, military unit, intelligence agency, embassy, school, labor union, business, police department, fire department, university, sports club), or a private chapel. The term chaplaincy refers to the chapel, facility or department in which one or more chaplains carry out their role.
SacramentA sacrament is a Christian rite that is recognized as being particularly important and significant. There are various views on the existence, number and meaning of such rites. Many Christians consider the sacraments to be a visible symbol of the reality of God, as well as a channel for God's grace. Many denominations, including the Catholic, Lutheran, Anglican, Methodist, and Reformed, hold to the definition of sacrament formulated by Augustine of Hippo: an outward sign of an inward grace, that has been instituted by Jesus Christ.
Minister (Christianity)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.
