In the Catholic Church the term minister enjoys a variety of usages. It most commonly refers to the person, whether lay or ordained, who is commissioned to perform some act on behalf of the Church. It is not a particular office or rank of clergy, as is the case in some other churches, but minister may be used as a collective term for vocational or professional pastoral leaders including clergy (bishops, deacons, priests) and non-clergy (theologians and lay ecclesial ministers). It is also used in reference to the canonical and liturgical administration of sacraments, as part of some offices, and with reference to the exercise of the lay apostolate.
