In
Early Christian architecture the
templon was a barrier dividing off the sanctuary from the rest of the church; in
Eastern Christianity this developed into different arrangements from those of the Western church, with the sanctuary often not visible to the congregation. In the West the
ciborium, an open-walled but usually roofed structure sheltering the altar, became common, and was originally fitted with curtains that were drawn and pulled back at different points in the Mass, in a way that some
Oriental Orthodox churches still practice today.
Church of the Good Shepherd (Rosemont, Pennsylvania), USA, designed by master
blacksmith Samuel Yellin A large (or "deep") chancel made most sense in monasteries and cathedrals where there was a large number of singing clergy and boys from a
choir school to occupy the choir. In many orders "choir monk" was a term used to distinguish the educated monks who had taken full vows, or were training to do so, from another class, called "lay brothers" or other terms, who had taken lesser vows and mostly did manual tasks, including farming the monastery's land. These usually sat in the nave, with any lay congregation. Following the exposition of the doctrine of
transubstantiation at the fourth
Lateran Council of 1215, clergy were required to ensure that the
blessed sacrament was to be kept protected from irreverent access or abuse; and accordingly the area of the church used by the lay congregation was to be screened off from that used by the clergy. This distinction was enforced by the development of
canon law, by which the construction and upkeep of the chancel was the responsibility of the
rector, whereas the construction and upkeep of the nave
was the responsibility of the
parish. Barriers demarcating the chancel became increasingly elaborate, but were largely swept away after both the
Protestant Reformation and then the
Counter-Reformation prioritized the congregation having a good view of what was happening in the chancel. Now the low
communion rail is generally the only barrier; despite being essentially a Counter-Reformation invention, this has proved useful and accepted in the Protestant churches that dispense communion. However the screen enjoyed a small revival in the 19th century, after the passionate urgings of
Augustus Pugin, who wrote
A Treatise on Chancel Screens and Rood Lofts, and others. After the Reformation Protestant churches generally moved the altar (now often called the
communion table) forward, typically to the front of the chancel, and often used lay choirs who were placed in a gallery at the west end. The rear of deep chancels became little used in churches surviving from the Middle Ages, and new churches very often omitted one. With the emphasis on sermons, and their audibility, some churches simply converted their chancels to seat part of the congregation. In 19th-century England one of the battles of the
Cambridge Camden Society, the architectural wing of the
Anglo-Catholics in the
Church of England, was to restore the chancel as a necessary part of a church. By pushing the altar back to its medieval position and having the choir used by a lay choir, they were largely successful in this, although the harder end of the
High Church objected to allowing a large group of laity into the chancel. Different approaches to worship in the 20th century again tended to push altars in larger churches forward, to be closer to the congregation, and the chancel again risks being a less used area of the church. ==References==
