In certain Christian denominations, 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.
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, ecclesiastic, and cleric, while clerk in holy orders has a long history but is rarely used.
A deacon is a member of the diaconate, an office in Christian churches that is generally associated with service of some kind, but which varies among theological and denominational traditions. Major Christian churches, such as the Catholic Church, the Oriental Orthodox Churches, the Eastern Orthodox Church, the Scandinavian Lutheran Churches, the Methodist Churches, the Anglican Communion, and the Free Church of England, view the diaconate as an order of ministry.
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.
Ordination is the process by which individuals are consecrated, that is, set apart and elevated from the laity class to the clergy, who are thus then authorized to perform various religious rites and ceremonies. The process and ceremonies of ordination vary by religion and denomination. One who is in preparation for, or who is undergoing the process of ordination is sometimes called an ordinand. The liturgy used at an ordination is sometimes referred to as an ordination.
Clerical celibacy is the requirement in certain religions that some or all members of the clergy be unmarried. Clerical celibacy also requires abstention from deliberately indulging in sexual thoughts and behavior outside of marriage, because these impulses are regarded as sinful.
Minor orders are ranks of church ministry. In the Catholic Church, the predominating Latin Church formerly distinguished between the major orders —priest, deacon and subdeacon—and four minor orders—acolyte, exorcist, lector, and porter. In 1972, the minor orders were renamed "ministries", with those of lector and acolyte being kept throughout the Latin Church. In the Eastern Orthodox Church, the three minor orders in use are those of subdeacon, reader and chanter.
Clerical marriage is the practice of allowing Christian clergy to marry. This practice is distinct from allowing married persons to become clergy. Clerical marriage is admitted among Protestants, including both Anglicans and Lutherans. Some Protestant clergy and their children have played an essential role in literature, philosophy, science, and education in Early Modern Europe.
An archdeacon is a senior clergy position in the Church of the East, Chaldean Catholic Church, Syriac Orthodox Church, Anglican Communion, St Thomas Christians, Eastern Orthodox churches and some other Christian denominations, above that of most clergy and below a bishop. In the High Middle Ages it was the most senior diocesan position below a bishop in the Catholic Church. An archdeacon is often responsible for administration within an archdeaconry, which is the principal subdivision of the diocese. The Oxford Dictionary of the Christian Church has defined an archdeacon as "A cleric having a defined administrative authority delegated to him by the bishop in the whole or part of the diocese." The office has often been described metaphorically as oculus episcopi, the "bishop's eye".
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.
Incardination is the formal term in the Catholic Church for a clergyman being under a bishop or other ecclesiastical superior. It is also sometimes used to refer to laity who may transfer to another part of the church. Examples include transfers from the Western Latin Church to an Eastern Catholic Church or from a territorial diocese to one of the three personal ordinariates for former Anglicans.
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.
The Anglican ministry is both the leadership and agency of Christian service in the Anglican Communion. "Ministry" commonly refers to the office of ordained clergy: the threefold order of bishops, priests and deacons. More accurately, Anglican ministry includes many laypeople who devote themselves to the ministry of the church, either individually or in lower/assisting offices such as lector, acolyte, sub-deacon, Eucharistic minister, cantor, musicians, parish secretary or assistant, warden, vestry member, etc. Ultimately, all baptized members of the church are considered to partake in the ministry of the Body of Christ.
The Priestly Society of Saint Josaphat Kuntsevych (SSJK) is a society of traditionalist priests and seminarians originating from the Ukrainian Greek Catholic Church which is led by the excommunicated priest Basil Kovpak. It is based in Riasne, Lviv, Western Ukraine. In Lviv, the society maintains a seminary, at which currently thirty students reside, and takes care of a small convent of Basilian sisters. The SSJK is affiliated with the Society of St. Pius X and Holy Orders are conferred by the latter society's bishops in the Roman Rite. The SSJK clergymen, however, exclusively follow a version of Slavonic Byzantine Rite in the Ruthenian recension.
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 are a priestly order 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.
Clerical celibacy is the discipline within the Catholic Church by which only unmarried men are ordained to the episcopate, to the priesthood in the Latin Church, and similarly to the diaconate. In other autonomous particular churches, the discipline applies only to the episcopate.
In the Catholic Church, a bishop is an ordained minister who holds the fullness of the sacrament of holy orders and is responsible for teaching doctrine, governing Catholics in his jurisdiction, sanctifying the world and representing the Church. Catholics trace the origins of the office of bishop to the apostles, who it is believed were endowed with a special charism and office by the Holy Spirit at Pentecost. Catholics believe this special charism and office has been transmitted through an unbroken succession of bishops by the laying on of hands in the sacrament of holy orders.
In the liturgical traditions of the Catholic Church, the term ordination refers to the means by which a person is included in one of the holy orders of bishops, priests or deacons. The teaching of the Catholic Church on ordination, as expressed in the 1983 Code of Canon Law, the Catechism of the Catholic Church, and the apostolic letter Ordinatio sacerdotalis, is that only a Catholic male validly receives ordination, and "that the Church has no authority whatsoever to confer priestly ordination on women and that this judgment is to be definitively held by all the Church's faithful." In other words, the male priesthood is not considered by the church a matter of policy but an unalterable requirement of God. As with priests and bishops, the church ordains only men as deacons.
A personal ordinariate for former Anglicans, shortened as personal ordinariate or Anglican ordinariate, is an ordinariate, a canonical structure within the Catholic Church established in order to enable "groups of Anglicans" and Methodists to join the Catholic Church while preserving elements of their liturgical and spiritual patrimony.
The first Study Commission on the Women's Diaconate was established in August 2016 by Pope Francis to review the theology and history of the ministry of women deacons (deaconesses) in the Roman Catholic Church. The commission report was not published. After the Amazonian synod, Pope Francis promised to re-open this commission. He established a second commission instead in April 2020.
