Early Middle Ages - Christianity West and East

Christianity West and East

From the early Christians, early medieval Christians inherited a church united by major creeds, a stable Biblical canon, and a well-developed philosophical tradition. The history of medieval Christianity traces Christianity during the Middle Ages - the period after the fall of the Roman Empire until the Protestant Reformation, considered the start of the modern era.

During the early Middle Ages, the divide between Eastern and Western Christianity widened, paving the way for the East-West Schism in the 11th century. In the West, the power of the Bishop of Rome expanded. In 607, Boniface III became the first Bishop of Rome to use the title Pope. Pope Gregory the Great used his office as a temporal power, expanded Rome's missionary efforts to the British Isles, and laid the foundations for the expansion of monastic orders. Roman church traditions and practices gradually replaced local variants, including Celtic Christianity in Great Britain and Ireland. In the East, the conquests of Islam reduced the power of the Greek-speaking patriarchates. Various barbarian tribes went from raiding and pillaging the island to settling and invading. They were entirely pagan, having never been part of the Empire, and although they experienced Christian influence from the surrounding peoples, such as those who were converted by the mission of St. Augustine sent by Pope Gregory the Great.
