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.
An altar is a table or platform for the presentation of religious offerings, for sacrifices, or for other ritualistic purposes. Altars are found at shrines, temples, churches, and other places of worship. They are used particularly in paganism, Christianity, Buddhism, Hinduism, Judaism, modern paganism, and in certain Islamic communities around Caucasia and Asia Minor. Many historical-medieval faiths also made use of them, including the Roman, Greek, and Norse religions.
A sanctuary lamp, chancel lamp, altar lamp, everlasting light, or eternal flame is a light that shines before the altar of sanctuaries in many Jewish and Christian places of worship. Prescribed in Exodus 27:20-21 of the Torah, this icon has taken on different meanings in each of the religions that have adopted it. The passage, which refers to prescriptions for the tabernacle, states:
And thou shalt command the children of Israel, that they bring thee pure oil olive beaten for the light, to cause the lamp to burn always. In the tabernacle of the congregation without the veil, which is before the testimony, Aaron and his sons shall order it from evening to morning before the LORD: it shall be a statute for ever unto their generations on the behalf of the children of Israel. (KJV)
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.
Genuflection or genuflexion is the act of bending a knee to the ground, as distinguished from kneeling which more strictly involves both knees. From early times, it has been a gesture of deep respect for a superior. Today, the gesture is common in the Christian religious practices of the Anglicanism, Lutheranism, the Catholic Church, and Western Rite Orthodoxy. The Latin word genuflectio, from which the English word is derived, originally meant kneeling with both knees rather than the rapid dropping to one knee and immediately rising that became customary in Western Europe in the Middle Ages. It is often referred to as "going down on one knee" or "bowing the knee". In Western culture, one genuflects on the left knee to a human dignitary, whether ecclesiastical or civil, while, in Christian churches and chapels, one genuflects on the right knee when the Sacrament is not exposed but in a tabernacle or veiled.
A monstrance, also known as an ostensorium, is a vessel used in Roman Catholic, Old Catholic, High Church Lutheran and Anglican churches for the display on an altar of some object of piety, such as the consecrated Eucharistic Sacramental bread (host) during Eucharistic adoration or during the Benediction of the Blessed Sacrament. A monstrance may also serve as a reliquary for the public display of relics of some saints. The word monstrance comes from the Latin word monstrare, while the word ostensorium comes from the Latin word ostendere. Either term, each expressing the concept of "showing", can refer to a vessel intended for the exposition of the Blessed Sacrament, but ostensorium has only this meaning.
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.
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.
In Christianity, a Eucharistic miracle is any miracle involving the Eucharist. The Roman Catholic, Lutheran, Oriental Orthodox, Eastern Orthodox, Moravian and Anglican Churches believe that Christ is really made manifest in the Eucharist and deem this a Eucharistic miracle; however, this is to be distinguished from other manifestations of God. The Catholic Church distinguishes between divine revelation, such as the Eucharist, and private revelation, such as Eucharistic miracles. In general, reported Eucharistic miracles usually consist of unexplainable phenomena such as consecrated Hosts visibly transforming into myocardium tissue, being preserved for extremely long stretches of time, surviving being thrown into fire, bleeding, or even sustaining people for decades.
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.
In the Roman Rite of the Catholic Church, Lutheranism, Methodism and Anglicanism, an altar bell is typically a small hand-held bell or set of bells. The primary reason for the use of such bells is to create a “joyful noise to the Lord” as a way to give thanks for the miracle taking place atop the altar.
The ceremonial use of lights occurs in liturgies of various Christian Churches, as well as in Jewish, Zoroastrian, and Hindu rites and customs.
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.
An ambry is a recessed cabinet in the wall of a Christian church for storing sacred vessels and vestments. They are sometimes near the piscina, but more often on the opposite side. The word also seems in medieval times to have been commonly used for any closed cupboard or even a bookcase.
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 altar of repose is a temporary altar where the Communion hosts consecrated on Maundy Thursday during the Mass of the Lord's Supper are placed, or "reserved", for use on the following day, Good Friday.
The altar in the Catholic Church is used for celebrating the Sacrifice of the Mass.
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."
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.
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 rather than by his body being physically eaten. The Reformed doctrine of real presence is called "pneumatic presence".
