Altar - Christianity

Christianity

The word "altar", in Greek θυσιαστήριον (see:θυσία), appears twenty-four times in the New Testament. Significantly, Hebrews 13:10 shows Christians having an altar of which those who did not believe in Jesus could not partake, a reference to the eternal, once-for-all sacrifice of Jesus Christ, thus fulfilling the sacrificial laws of the Old Testament. In Catholic and Orthodox Christian theology, the Eucharist is a re-presentation, in the literal sense of the one sacrifice being made "present again". Hence, the table upon which the Eucharist is consecrated is called an altar.

Altars occupy a prominent place in the sanctuaries of all churches of the Catholic Church, Eastern Orthodoxy, Oriental Orthodoxy and the Church of the East, and in some Anglican churches. They are also found in a minority of Protestant worship places, though the term "communion table", which avoids the sacrificial connotations of an altar, is generally preferred. The altar plays a central role in the celebration of the Eucharist, which takes place at the altar on which the bread and the wine for consecration are placed.

The area around the altar is seen as endowed with greater holiness, and is usually physically distinguished from the rest of the church, whether by a permanent structure such as an iconostasis, a rood screen or altar rails, by a curtain that can be closed at more solemn moments of the liturgy, as in the Armenian Apostolic Church and Armenian Catholic Church, or simply by the general architectural layout. The altar is often on a higher elevation than the rest of the church. In Reformed and Anabaptist churches, a table, often called a "communion table", serves an analogous function. In some colloquial usage, the word "altar" is used to denote the altar rail also, although this usage is technically incorrect.

Churches generally have a single altar, although in the West, as a result of the former abandonment of concelebration of Mass, so that priests always celebrated Mass individually, larger churches have had one or more side chapels, each with its own altar. The main altar was also referred to as the "high altar". Since the revival of concelebration in the West, the Roman Missal recommends that in new churches there should be only one altar, "which in the gathering of the faithful will signify the one Christ and the one Eucharist of the Church." But most Western churches of an earlier period, whether Roman Catholic or Anglican, may have a high altar in the main body of the church, with one or more adjoining chapels, each with its own altar, at which the Eucharist may be celebrated on weekdays.

Architecturally, there are two types of altars: those that are attached to the eastern wall of the chancel, and those that are free-standing and can be walked around, for instance when incensing the altar.

In the earliest days of the Church, the Eucharist appears to have been celebrated on portable altars set up for the purpose. Some historians hold that, during the persecutions, the Eucharist was celebrated among the tombs in the Catacombs of Rome, using the sarcophagi (see sarcophagus) of martyrs as altars on which to celebrate. Other historians dispute this, but it is thought to be the origin of the tradition of placing relics beneath the altar.

When Christianity was legalized under Constantine the Great and Licinius, formal church buildings were built in great numbers, normally with free-standing altars in the middle of the sanctuary, which in all the earliest churches built in Rome was at the west end of the church. "When Christians in fourth-century Rome could first freely begin to build churches, they customarily located the sanctuary towards the west end of the building in imitation of the sanctuary of the Jerusalem Temple. Although in the days of the Jerusalem Temple the High Priest indeed faced east when sacrificing on Yom Kippur, the sanctuary within which he stood was located at the western end of the Temple. The Christian replication of the layout and the orientation of the Jerusalem Temple helped to dramatize the eschatological meaning attached to the sacrificial death of Jesus the High Priest in the Epistle to the Hebrews." The ministers (bishop, priests, deacons, subdeacons, acolytes), celebrated the Eucharist facing east, towards the entrance. Some hold that for the central part of the celebration the congregation faced the same way. After the sixth century the contrary orientation prevailed, with the entrance to the west and the altar at the east end. Then the ministers and congregation all faced east during the whole celebration; and in Western Europe altars began, in the Middle Ages, to be permanently placed against the east wall of the chancel.
