Cathedra

From Wikipedia, the free encyclopedia

A cathedra (Latin for "chair") is the chair or throne of a bishop. It is a symbol of teaching authority in the Roman Catholic Church and the Orthodox Church, and has in some sense remained such in the Anglican Communion and in Lutheran churches. Cathedra is the Latin word for a chair with armrests; its Roman connotations of authority reserved for the Emperor were adopted by bishops after the 4th century. In this sense, it is sometimes referred to as a "bishop's throne." A church into which a cathedra is installed is called a cathedral or co-cathedral — the seat of a particular church called a diocese.

[edit] Cathedra Petri

The definitive example of a cathedra is that encased within the Triumph of the cathedra Petri designed by Gian Lorenzo Bernini in 1657 and completed and installed in 1666. As early as the 8th century, an ancient wooden chair overlaid with ivory plaques depicting the Labors of Hercules and some of the signs of the Zodiac was venerated as the episcopal chair of St. Peter himself. In fact, it is a Byzantine throne enframing fragments of acacia wood encased in the oak carcass and reinforced with iron bands. Several rings facilitated its transportation during processions. Pope Urban VIII commissioned Bernini to build a sumptuous monument which would present this relic in a truly triumphant manner. Bernini's gilded bronze throne, richly ornamented with bas-reliefs encloses the relic. On January 17, 1666 it was solemnly set above the altar of Saint Peter's Basilica in Vatican City. Four over-lifesized sculptures of Doctors of the Church form an honor guard: St. Ambrose, St. Athanasius (left); and St. John Chrysostom, and St. Augustine (right).

Celebrated on 22 February in accordance with the calendar of saints, the Feast of Cathedra Petri honors the founding of the church in Rome and gives thanks for the work of Saint Peter.

[edit] Chair of St. Augustine

The Chair of St. Augustine represents one of the most ancient extant cathedrae in use. Named for the first Archbishop of Canterbury, St. Augustine of Canterbury, it is made of Purbeck or Bethesda marble and dates to sometime between the 6th and 12th centuries. Those who argue for an older date suggest that it may have been used to crown the kings of Kent. Canterbury Cathedral, in which the cathedra is housed, maintains that the chair was once part of the furnishings of the shrine of St. Thomas Becket, since dismantled [1]. Since antiquity, it has always a place in the triple enthronement of an Archbishop of Canterbury. He is seated on the throne in the quire as Diocesan Bishop, in the chapter house as titular abbot, and in St. Augustine's chair as Primate of All England. This is the only occasion in which the cathedra is used. A second one is used for other occasions in which the archbishop is present.

[edit] Ex cathedra

The term ex cathedra, meaning "from the throne", is used to designate official pronouncements of the pope when he teaches the whole world. As a throne or armchair symbolizes the power to teach, the cathedra in this case refers to the teaching authority over the whole church rather than to an actual chair. According to Catholic dogma, the pope's statements ex cathedra are infallible. In Anglican episcopal governance, episcopal teaching is conditioned by synodical governance, and so bishops cannot be said to speak ex cathedra in this way - although they may jocularly be said to do so.

[edit] Placement

The cathedra of the Catholic Diocese of Honolulu is placed behind the altar. The cathedral church interior was reformed for the liturgical changes.

The traditional position of the cathedra was in the apse, behind the high altar, which had been the position of the magistrate in the apse of the Roman basilica which provided the model type—and sometimes the actual structures—for early Christian basilicas. In the Middle Ages, as altars came to be placed against the wall of the apse, the practice of placing the cathedra to one side (mostly left) became standard.

In the Roman Catholic Church since the Second Vatican Council, the altar is often free-standing and faces the people, so that, according to its advocates, priest and people pray in a mutual dialogue around "the table of the Lord"; in cathedrals built or renovated after the reforms of Vatican II, the cathedra is often placed behind the altar, as in ancient Roman basilicas. In Anglican practice, the cathedra tends to be placed to one side in the quire, although in more contemporary practice, it is commonly placed on the gospel side of the chancel (ie., to the left of the altar, as one looks at it from the front).
