Constantine I (Latin: Flavius Valerius Constantinus), also known as Constantine the Great, was a Roman emperor from AD 306 to 337 and the first Roman emperor to convert to Christianity. He played a pivotal role in elevating the status of Christianity in Rome, decriminalizing Christian practice and ceasing Christian persecution in a period referred to as the Constantinian shift. This initiated the cessation of the established ancient Roman religion. Constantine is also the originator of the religiopolitical ideology known as Constantinianism, which epitomizes the unity of church and state, as opposed to separation of church and state. He founded the city of Constantinople and made it the capital of the Empire, which remained so for over a millennium.

Although Constantine lived much of his life as a pagan and later as a catechumen, he began to favour Christianity beginning in 312, finally becoming a Christian.

He began his career by campaigning in the eastern provinces (against the Persians) before being recalled in the west (in AD 305) to fight alongside his father in the province of Britannia. After his father's death in 306, Constantine was proclaimed as augustus (emperor) by his army at Eboracum (York, England). He eventually emerged victorious in the civil wars against emperors Maxentius and Licinius to become the sole ruler of the Roman Empire by 324.

Constantine's share of the empire consisted of Britain, Gaul, and Spain, and he commanded one of the largest Roman armies which was stationed along the important Rhine frontier. He remained in Britain after his promotion to emperor, driving back the tribes of the Picts and securing his control in the northwestern dioceses. He completed the reconstruction of military bases begun under his father's rule, and he ordered the repair of the region's roadways. He then left for Augusta Treverorum (Trier) in Gaul, the Tetrarchic capital of the northwestern Roman Empire.

A chapter house or chapterhouse is a building or room that is part of a cathedral, monastery or collegiate church in which meetings are held. When attached to a cathedral, the cathedral chapter meets there. In monasteries, the whole community often met there daily for readings and to hear the abbot or senior monks talk. When attached to a collegiate church, the dean, prebendaries and canons of the college meet there. The rooms may also be used for other meetings of various sorts; in medieval times monarchs on tour in their territory would often take them over for their meetings and audiences. Synods, ecclesiastical courts and similar meetings often took place in chapter houses.

A choir, also sometimes called quire, is the area of a church or cathedral that provides seating for the clergy and church choir. It is in the western part of the chancel, between the nave and the sanctuary, which houses the altar and Church tabernacle. In larger medieval churches it contained choir-stalls, seating aligned with the side of the church, so at right-angles to the seating for the congregation in the nave. Smaller medieval churches may not have a choir in the architectural sense at all, and they are often lacking in churches built by all denominations after the Protestant Reformation, though the Gothic Revival revived them as a distinct feature.

As an architectural term "choir" remains distinct from the actual location of any singing choir – these may be located in various places, and often sing from a choir-loft, often over the door at the liturgical western end. In modern churches, the choir may be located centrally behind the altar, or the pulpit. The place where the singers are based is sometimes called the ritual choir, as opposed to the architectural choir or constructional choir.

The archbishop of York is a senior bishop in the Church of England, second only to the archbishop of Canterbury. The archbishop is the diocesan bishop of the Diocese of York and the metropolitan bishop of the province of York, which covers the northern regions of England (north of the Trent) as well as the Isle of Man.

There was a bishop in Eboracum (Roman York) from very early times; during the Middle Ages, it was thought to have been one of the dioceses established by the legendary King Lucius. Bishops of York are known to have been present at the councils of Arles (Eborius) and Nicaea (unnamed). However, this early Christian community was later destroyed by the pagan Anglo-Saxons and there is no direct succession from these bishops to the post-Augustinian ones.

The surname of the archbishop of York is not always used in formal documents; often only the first name and see are mentioned. The archbishop is legally entitled to sign his name as "Ebor" (from the Latin for York). The right to use a title as a legal signature is only permitted to bishops, peers of the Realm and peers by courtesy. The current archbishop of York usually signs as "+Stephen Ebor".

The Bishop of Beverley is a Church of England suffragan bishop. The title takes its name after the town of Beverley in the East Riding of Yorkshire, England.

The suffragan bishop was originally to assist the Archbishop of York in overseeing the Diocese of York, but after 1923 the position fell into abeyance. The See was revived under the Suffragans Nomination Act 1888 by Order in Council dated 8 February 1994,[2] as a Provincial Episcopal Visitor for the Province of York. The bishop has responsibility for those parishes in 9 dioceses of the province who do not accept the sacramental ministry of bishops who have participated in the ordination of women.
