In certain Christian churches, holy orders are the ordained ministries of bishop, priest (presbyter), and deacon, and the sacrament or rite by which candidates are ordained to those orders. Churches recognizing these orders include the Catholic Church, the Eastern Orthodox, Oriental Orthodox, Anglican, Assyrian, Old Catholic, Independent Catholic and some Lutheran churches. Except for Lutherans and some Anglicans, these churches regard ordination as a sacrament. The Anglo-Catholic tradition within Anglicanism identifies more with the Roman Catholic position about the sacramental nature of ordination.
Clergy are formal leaders within established religions. Their roles and functions vary in different religious traditions, but usually involve presiding over specific rituals and teaching their religion's doctrines and practices. Some of the terms used for individual clergy are clergyman, clergywoman, clergyperson, churchman, and cleric, while clerk in holy orders has a long history but is rarely used.
Tonsure is the practice of cutting or shaving some or all of the hair on the scalp as a sign of religious devotion or humility. The term originates from the Latin word tonsura and referred to a specific practice in medieval Catholicism, abandoned by papal order in 1972. Tonsure can also refer to the secular practice of shaving all or part of the scalp to show support or sympathy, or to designate mourning. Current usage more generally refers to cutting or shaving for monks, devotees, or mystics of any religion as a symbol of their renunciation of worldly fashion and esteem.
Subdeacon is a minor order or ministry for men in various branches of Christianity. The subdeacon has a specific liturgical role and is placed between the acolyte and the deacon in the order of precedence.
An acolyte is an assistant or follower assisting the celebrant in a religious service or procession. In many Christian denominations, an acolyte is anyone performing ceremonial duties such as lighting altar candles. In others, the term is used for one who has been inducted into a particular liturgical ministry, even when not performing those duties.
In some religions, an exorcist is a person who is believed to be able to cast out the devil or performs the ridding of demons or other supernatural beings who are alleged to have possessed a person, or (sometimes) a building or even an object. An exorcist can be a specially prepared or instructed person including: priest, a nun, a monk, a witch doctor (healer), a shaman, a psychic or a geomancer.
An ostiarius, a Latin word sometimes anglicized as ostiary but often literally translated as porter or doorman, originally was a servant or guard posted at the entrance of a building. See also gatekeeper.
Minor orders are ranks of church ministry lower than major orders.
A crucifer or cross-bearer is, in some Christian churches, a person appointed to carry the church's processional cross, a cross or crucifix with a long staff, during processions at the beginning and end of the service.
In some Christian churches, a reader or lector is responsible for reading aloud excerpts of scripture at a liturgy. In early Christian times the reader was of particular value due to the rarity of literacy.
The hierarchy of the Catholic Church consists of its bishops, priests, and deacons. In the ecclesiological sense of the term, "hierarchy" strictly means the "holy ordering" of the Church, the Body of Christ, so to respect the diversity of gifts and ministries necessary for genuine unity.
In persona Christi is a Latin phrase meaning "in the person of Christ", an important concept in Roman Catholicism and, in varying degrees, to other Christian traditions, such as Lutheranism and Anglicanism. A priest is In persona Christi because he acts as Christ and as God. An extended term, In persona Christi capitis, “in the person of Christ the head,” was introduced by the bishops of the Vatican Council II in the Decree on the Ministry and Live of Priests, Presbyterorum Ordinis, December 7, 1965.
The sacrament of holy orders in the Catholic Church includes three orders: bishops, priests, and deacons, in decreasing order of rank, collectively comprising the clergy. In the phrase "holy orders", the word "holy" means "set apart for a sacred purpose". The word "order" designates an established civil body or corporation with a hierarchy, and ordination means legal incorporation into an order. In context, therefore, a group with a hierarchical structure that is set apart for ministry in the Church.
A lay cardinal was a cardinal in the College of Cardinals of the Catholic Church who was a lay person, that is, who had never have been given major orders through ordination as a deacon, priest, or bishop.
The priesthood is the office of the ministers of religion, who have been commissioned ("ordained") with the Holy orders of the Catholic Church. Technically, bishops and deacons are priestly orders as well; however, in layman's terms priest refers only to presbyters and pastors. The church's doctrine also sometimes refers to all baptised (lay) members as the "common priesthood", which can be confused with the ministerial priesthood of the consecrated clergy.
There are seven sacraments of the Catholic Church, which according to Catholic theology were instituted by Jesus and entrusted to the Church. Sacraments are visible rites seen as signs and efficacious channels of the grace of God to all those who receive them with the proper disposition.
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 and non-clergy. 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.
Catholic laity are the ordinary members of the Catholic Church who are neither clergy nor recipients of Holy Orders or vowed to life in a religious order or congregation. Their mission, according to the Second Vatican Council, is to "sanctify the world".
In the canon law of the Catholic Church, a person is a subject of certain legal rights and obligations. Persons may be distinguished between physical and juridic persons. Juridic persons may be distinguished as collegial or non-collegial, and public or private juridic persons. The Holy See and the Catholic Church as such are not juridic persons, since juridic persons are created by ecclesiastical law. Rather, they are moral persons by divine law.
Spiritus Domini is an apostolic letter in the form of a motu proprio by Pope Francis signed on 10 January 2021 and released the next day. It changed the 1983 Code of Canon Law to allow women to be admitted to the instituted ministries of acolyte and lector (reader), which had until then been exclusively available to men.
