The Eucharist, also known as Holy Communion, Blessed Sacrament and the Lord's Supper, is a Christian rite that is considered a sacrament in most churches, and as an ordinance in others. Christians believe that the rite was instituted by Jesus at the Last Supper, the night before his crucifixion, giving his disciples bread and wine. Passages in the New Testament state that he commanded them to "do this in memory of me" while referring to the bread as "my body" and the cup of wine as "the blood of my covenant, which is poured out for many". According to the Synoptic Gospels this was at a Passover meal.
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.
Mass is the main Eucharistic liturgical service in many forms of Western Christianity. The term Mass is commonly used in the Catholic Church, Western Rite Orthodoxy, Old Catholicism, and Independent Catholicism. The term is also used in some Lutheran churches, as well as in some Anglican churches, and on rare occasion by other Protestant churches.
Sacrifice is the offering of material possessions or the lives of animals or humans to a deity as an act of propitiation or worship. Evidence of ritual animal sacrifice has been seen at least since ancient Hebrews and Greeks, and possibly existed before that. Evidence of ritual human sacrifice can also be found back to at least pre-Columbian civilizations of Mesoamerica as well as in European civilizations. Varieties of ritual non-human sacrifices are practiced by numerous religions today.
The priesthood of all believers is either the general Christian belief that all Christians form a common priesthood, or, alternatively, the specific Protestant belief that this universal priesthood precludes the ministerial priesthood found in some other churches, including the Catholic and Eastern Orthodox.
Confession, in many religions, is the acknowledgment of sinful thoughts and actions. This may occur directly to a god or to fellow people.
The real presence of Christ in the Eucharist is the Christian doctrine that Jesus Christ is present in the Eucharist, not merely symbolically or metaphorically, but in a true, real and substantial way.
Absolution is a theological term for the forgiveness imparted by ordained Christian priests and experienced by Christian penitents. It is a universal feature of the historic churches of Christendom, although the theology and the practice of absolution vary between Christian denominations.
Memorialism is the belief held by some Christian denominations that the elements of bread and wine in the Eucharist are purely symbolic representations of the body and blood of Jesus Christ, the feast being established only or primarily as a commemorative ceremony. The term comes from the Gospel of Luke 22:19: "Do this in remembrance of me", and the attendant interpretation that the Lord's Supper's chief purpose is to help the participant remember Jesus and his sacrifice on the Cross.
The threefold office of Jesus Christ is a Christian doctrine based upon the teachings of the Old Testament of which Christians hold different views. It was described by Eusebius and more fully developed by John Calvin.
Eucharistic theology is a branch of Christian theology which treats doctrines concerning the Holy Eucharist, also commonly known as the Lord's Supper and Holy Communion. It exists exclusively in Christianity, as others generally do not contain a Eucharistic ceremony.
Catholicity is a concept of pertaining to beliefs and practices that are widely accepted by numerous Christian denominations, most notably by those Christian denominations that describe themselves as catholic in accordance with the Four Marks of the Church, as expressed in the Nicene Creed formulated at the First Council of Constantinople in 381: "[I believe] in one, holy, catholic, and apostolic Church." The English adjective catholic is derived from the Ancient Greek adjective καθολικός, meaning "general", "universal". Thus, "catholic" means that in the Church the wholeness of the Christian faith, full and complete, all-embracing, and with nothing lacking, is proclaimed to all people without excluding any part of the faith or any class or group of people. An early definition for what is "catholic" was summarized in what is known as the Vincentian Canon in the 5th century Commonitory: "what has been believed everywhere, always, and by all."
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. In Catholic theology, a priest is In persona Christi because, in the sacraments he administers, it is God and Christ who acts through the instrumentality of the priest. 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.
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.
In Lutheranism, the Eucharist refers to the liturgical commemoration of the Last Supper. Lutherans believe in the real presence of Christ in the Eucharist, affirming the doctrine of sacramental union, "in which the body and blood of Christ are truly and substantially present, offered, and received with the bread and wine."
The Lutheran sacraments are "sacred acts of divine institution". They are also defined as “an outward and visible sign of an inward and spiritual grace.”.
A 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 Roman Catholic, Lutheran, Presbyterian 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. Sacraments signify God's grace in a way that is outwardly observable to the participant.
In Reformed theology, the Lord's Supper or Eucharist is a sacrament that spiritually nourishes Christians and strengthens their union with Christ. The outward or physical action of the sacrament is eating bread and drinking wine. Reformed confessions, which are official statements of the beliefs of Reformed churches, teach that Christ's body and blood are really present in the sacrament, and that believers receive, in the words of the Belgic Confession, "the proper and natural body and the proper blood of Christ." The primary difference between the Reformed doctrine and that of Catholic and Lutheran Christians is that for the Reformed, this presence is believed to be communicated in a spiritual manner by faith rather than by oral consumption. The Reformed doctrine of real presence is called "pneumatic presence".
