Apostolic succession is the method whereby the ministry of the Christian Church is considered by some Christian denominations to be derived from the apostles by a continuous succession, which has usually been associated with a claim that the succession is through a series of bishops. Those of the Catholic, Eastern Orthodox, Scandinavian Lutheran, Anglican, Oriental Orthodox, Church of the East, Hussite, Moravian and Old Catholic traditions maintain that "a bishop cannot have regular or valid orders unless he has been consecrated in this apostolic succession". These traditions do not always consider the episcopal consecrations of all of the other traditions as valid.
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.
A priest is a religious leader authorized to perform the sacred rituals of a religion, especially as a mediatory agent between humans and one or more deities. They also have the authority or power to administer religious rites; in particular, rites of sacrifice to, and propitiation of, a deity or deities. Their office or position is the "priesthood", a term which also may apply to such persons collectively. A priest may have the duty to hear confessions periodically, give marriage counseling, provide prenuptial counseling, give spiritual direction, teach catechism, or visit those confined indoors, such as the sick in hospitals and nursing homes.
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, cleric, ecclesiastic, and vicegerent while clerk in holy orders has a long history but is rarely used.
A pastor is the leader of a Christian congregation who also gives advice and counsel to people from the community or congregation. In Lutheranism, Catholicism, Eastern Orthodoxy, Oriental Orthodoxy and Anglicanism, pastors are always ordained. In Methodism, pastors may be either licensed or ordained.
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 commonly found in a book known as an Ordinal which provides the ordo for celebrations.
The laying on of hands is a religious practice. In Judaism semikhah accompanies the conferring of a blessing or authority.
In religious organizations, the laity consists of all members who are not part of the clergy, usually including any non-ordained members of religious orders, e.g. a nun or a lay brother. In both religious and wider secular usage, a layperson is a person who is not qualified in a given profession or does not have specific knowledge of a certain subject. The phrase "layman's terms" is used to refer to plain language that is understandable to the everyday person, as opposed to specialised terminology understood only by a professional.
In the Latter Day Saint movement, priesthood is the power and authority of God given to man, including the authority to perform ordinances and to act as a leader in the church. A group of priesthood holders is referred to as a quorum.
The Aaronic priesthood is the lesser of the two orders of priesthood recognized in the Latter Day Saint movement. The others are the Melchizedek priesthood and the rarely recognized Patriarchal priesthood. Unlike the Melchizedek priesthood, which is modeled after the authority of Jesus and the Twelve Apostles, or the Patriarchal priesthood, which is modeled after the authority of Abraham, the Aaronic priesthood is modeled after the priesthood of Aaron the Levite, the first high priest of the Hebrews, and his descendants. The Aaronic priesthood is thought to be a lesser or preparatory priesthood and an "appendage" of the more powerful Melchizedek priesthood.
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. 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.
Priest is a priesthood office in the Aaronic priesthood of denominations within the Latter Day Saint movement, including the Church of Jesus Christ of Latter-day Saints.
Elder is a priesthood office in the Melchizedek priesthood of denominations within the Latter Day Saint movement, including The Church of Jesus Christ of Latter-day Saints.
In Community of Christ, formerly the Reorganized Church of Jesus Christ of Latter Day Saints, priesthood is God's power and authority to minister in the church and to conduct God's business on Earth. Although the church believes that all Christians are called by their gifts and talents to the ministry, priesthood is seen as a particular expression of universal ministry to which all are called. In Community of Christ, both women and men can be ordained to the priesthood. All offices are deemed equal in importance, but the duties and responsibilities of each differ.
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.
Lay ecclesial ministry is the term adopted by the United States Conference of Catholic Bishops to identify the relatively new category of pastoral ministers in the Catholic Church who serve the Church but are not ordained. Lay ecclesial ministers are coworkers with the bishop alongside priests and deacons. In other contexts, these may be known as "lay pastoral workers", "pastoral assistants", etc.
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.
In Christianity, an elder is a person who is valued for wisdom and holds a position of responsibility and authority in a Christian group. In some Christian traditions an elder is an ordained person who serves a local church or churches and who has been ordained to a ministry of word, sacrament and order, filling the preaching and pastoral offices. In other Christian traditions, an elder may be a lay person serving as an administrator in a local congregation, or be ordained and serving in preaching or pastoral roles. There is a distinction between ordained elders and lay elders. The two concepts may be conflated in everyday conversation. In non-Christian world cultures the term elder refers to age and experience, and the Christian sense of elder is partly related to this.
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.
In Christianity, the laying on of hands is both a symbolic and formal method of invoking the Holy Spirit primarily during baptisms and confirmations, healing services, blessings, and ordination of priests, ministers, elders, deacons, and other church officers, along with a variety of other church sacraments and holy ceremonies.
