The formal history of the Church of England is traditionally dated by the Church to the Gregorian mission to England by Saint Augustine of Canterbury in AD 597.[1] As a result of Augustine's mission, Christianity in England, from Anglican (English) perspective, came under the authority of the Pope. However, in 1534 King Henry VIII declared himself to be supreme head of the Church of England. This resulted in a schism with the Papacy. As a result of this schism, many non-Anglicans consider that the Church of England only existed from the 16th century Protestant Reformation.
However, Christianity arrived in the British Isles around AD 47 during the Roman Empire according to Gildas's De Excidio et Conquestu Britanniae. Archbishop Restitutus and others are known to have attended the Council of Arles in 314. Christianity developed roots in Sub-Roman Britain and later Ireland, Scotland, and Pictland. The Anglo-Saxons (Germanic pagans who progressively seized British territory) during the 5th, 6th and 7th centuries, established a small number of kingdoms and evangelisation of the Anglo-Saxons was carried out by the successors of the Gregorian mission and by Celtic missionaries from Scotland. The church in Wales remained isolated and was only brought within the jurisdiction of English bishops several centuries later.
The Church of England became the established church by an Act of Parliament in the Act of Supremacy, beginning a series of events known as the English Reformation.[2] During the reign of Queen Mary I and King Philip, the church was fully restored under Rome in 1555. However, the pope's authority was again explicitly rejected after the accession of Queen Elizabeth I when the Act of Supremacy 1558 was passed. Catholic and Reformed factions vied for determining the doctrines and worship of the church. This ended with the 1558 Elizabethan Settlement, which developed the understanding that the church was to be "both Catholic and Reformed".[3]
