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.
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.
Full communion is a communion or relationship of full agreement among different Christian denominations or Christian individuals that share certain essential principles of Christian theology. Views vary among denominations on exactly what constitutes full communion, but typically when two or more denominations are in full communion it enables services and celebrations, such as the Eucharist, to be shared among congregants or clergy of any of them with the full approval of each.
Closed communion is the practice of restricting the serving of the elements of Holy Communion to those who are members in good standing of a particular church, denomination, sect, or congregation. Though the meaning of the term varies slightly in different Christian theological traditions, it generally means that a church or denomination limits participation either to members of their own church, members of their own denomination, or members of some specific class. This restriction is based on various parameters, one of which is baptism. See also intercommunion.
Open communion is the practice of some Protestant Churches of allowing members and non-members to receive the Eucharist. Many but not all churches that practice open communion require that the person receiving communion be a baptized Christian, and other requirements may apply as well. In Methodism, open communion is referred to as the open table, meaning that all may approach the Communion table.
Eucharistic adoration is a Eucharistic devotional practice primarily in Western Catholicism, but also to a lesser extent in certain Lutheran and Anglican traditions, in which the Blessed Sacrament is adored by the faithful. This practice may occur either when the Eucharist is exposed, or when it is not publicly viewable because it is reserved in a place such as a church tabernacle.
The Words of Institution are words echoing those of Jesus himself at his Last Supper that, when consecrating bread and wine, Christian Eucharistic liturgies include in a narrative of that event. Eucharistic scholars sometimes refer to them simply as the verba.
A tabernacle or a sacrament house is a fixed, locked box in which the Eucharist is stored as part of the "reserved sacrament" rite. A container for the same purpose, which is set directly into a wall, is called an aumbry.
Eucharistic theology is a branch of Christian theology which treats doctrines concerning the Holy Eucharist, also commonly known as the Lord's Supper. It exists exclusively in Christianity and related religions, as others generally do not contain a Eucharistic ceremony.
Ut unum sint is an encyclical by Pope John Paul II of 25 May 1995. It was one of 14 encyclicals issued by John Paul II. Cardinal Georges Cottier, Theologian emeritus of the Pontifical Household, was influential in drafting the encyclical.
During the Mass of the Faithful, the second part of the Mass, the elements of bread and wine are considered to have been changed into the veritable Body and Blood of Jesus Christ. The manner in which this occurs is referred to by the term transubstantiation, a theory of St. Thomas Aquinas, in the Roman Catholic Church. Members of the Orthodox, Anglican, and Lutheran communions also believe that Jesus Christ is really and truly present in the bread and wine, but they believe that the way in which this occurs must forever remain a sacred mystery. In many Christian churches some portion of the consecrated elements is set aside and reserved after the reception of Communion and referred to as the reserved sacrament. The reserved sacrament is usually stored in a tabernacle, a locked cabinet made of precious materials and usually located on, above, or near the high altar. In Western Christianity usually only the Host, from Latin: hostia, meaning "victim", is reserved, except where wine might be kept for the sick who cannot consume a host.
Catholicity is a concept 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.
Anglican eucharistic theology is diverse in practice, reflecting the comprehensiveness of Anglicanism. Its sources include prayer book rubrics, writings on sacramental theology by Anglican divines, and the regulations and orientations of ecclesiastical provinces. The principal source material is the Book of Common Prayer, specifically its eucharistic prayers and Article XXVIII of the Thirty-Nine Articles. Article XXVIII comprises the foundational Anglican doctrinal statement about the Eucharist, although its interpretation varies among churches of the Anglican Communion and in different traditions of churchmanship such as Anglo-Catholicism and Evangelical Anglicanism.
The Catholic Church has engaged in the modern ecumenical movement especially since the Second Vatican Council (1962-1965) and the issuing of the decree Unitatis redintegratio and the declaration Dignitatis humanae. It was at the Council that the Pontifical Council for Promoting Christian Unity was created. Those outside of the Catholic Church were categorised as heretics or schismatics, but in many contexts today, to avoid offence, the euphemism "separated brethren" is used.
Eucharist is the name that Catholics give to the sacrament by which, according to their belief, the body and blood of Christ are present in the bread and wine that are consecrated during the Catholic eucharistic liturgy, generally known as the Mass. The definition of the Eucharist in the 1983 Code of Canon Law as the sacrament where Christ himself "is contained, offered, and received" points to the three aspects of the Eucharist according to Catholic theology: the real presence of Christ in the Eucharist, Holy Communion, and the holy sacrifice of the Mass.
Receptionism is a form of Anglican eucharistic theology which teaches that during the Eucharist the bread and wine remain unchanged after the consecration, but when communicants receive the bread and wine, they also receive the body and blood of Christ by faith. It was a common view among Anglicans in the 16th and 17th centuries, and prominent theologians who subscribed to this doctrine were Thomas Cranmer and Richard Hooker.
Redemptionis sacramentum is an instruction on the proper way to celebrate Mass in the Roman Rite and others, and considered as well the adoration of the Blessed Sacrament. It was issued by the Congregation for Divine Worship and the Discipline of the Sacraments on 25 March 2004 over the signature of the Congregation's prefect, Cardinal Francis Arinze. It was designed to aid bishops in implementing the Roman Missal, issued in 2002. It follows Pope John Paul II's 2003 encyclical, Ecclesia de Eucharistia calling for an Instruction on the liturgical norms.
Spiritual communion is a Christian practice of desiring union with Jesus Christ in the Eucharist. It is used as a preparation for Mass and by individuals who cannot receive holy communion.
Dominicae Cenae is an apostolic letter written by Pope John Paul II concerning the Eucharist and its role in the life of the Church and the life of the priest. It also touches on other Eucharistic topics.
In the Catholic Church, communicatio in sacris, also called communicatio in divinis or communicatio in ritibus, designates the regulations for the partaking of a Catholic person to a non-Catholic sacrament or liturgical celebration, or for the partaking of a non-Catholic person to a Catholic sacrament or liturgical celebration. The expression is also used to refer to said acts of partaking themselves.
