The earliest introduction into England of Monasticism--originally founded in the East--has been attributed to Joseph of Arimathæa, who is credited with the founding of the monastery at Glastonbury. If this somewhat mythical statement cannot claim general acceptance on account of its antiquity, it is at least an acknowledged fact that Glastonbury was one of the earliest of monastic houses established in England. Bede tells us also that from the time of King Lucius A.D. 170, until that of the Emperor Diocletian, “the Britons kept the faith in quiet peace, inviolate and entire.” At the end of the 3rd or the beginning of the 4th century, Diocletian caused a general persecution of Christians, during which St Alban, proto-martyr of Britain, attested the reality of his faith; but happier days following in the reign of Constantine the Great, the early Church again prospered. We read that British bishops were present at such notable councils as those of Arles, A.D. 314, and Nicea in A.D. 325, etc., and though in 410 the Romans left Britain never to return, the good work, despite many rebuffs, still continued. An appeal was made to the Gallican Church for help and resulted in the mission of Germanus, Bishop of Auxerre, and Lupus, Bishop of Troyes, to Britain on the decision of the Council of Troyes. Churches were built, others restored, the numbers of bishops increased, and a greater religious devotion promoted in the Celtic race which to this day has never wholly died. St Germanus founded a Bishopric in the Isle of Man in A.D. 447--Glastonbury and St Albans received a particular share of attention from him, and that religious fervour was inspired among the people which later showed itself so strongly against the heathen invaders, and which is so graphically portrayed in romantic song and story associated with King Arthur and his Knights of the Round Table.
