CHRISTIANITY ARRIVED IN KHUMRY-WALES IN AD 37, in “the last year of Tiberius”. This is attested by the official historians of the Church of Rome, Cardinal Baronius, the Vatican Librarian, writing around AD 1530, and Cardinal Alford (Griffiths) – as well as by the British monks Gildas (Aneurin y Coed Aur), who lived AD 540-600, and Nennius, who wrote circa AD 800.
Later writers had to be very careful as Christianity officially arrived in Eastern England in AD 597, with Austin-Augustine of Canterbury, who converted the immigrant Saxons and Angles. Yet Austin met with seven British bishops in AD 600 at Aust in the west of Britain, on the Severn estuary. Pelagius, a British monk, had denied the doctrine of original sin as developed by Augustine of Hippo, arguing instead for free will. This was in the early AD 400’s. Before that, three named British bishops had attended the Council of Sardonica in AD 347 and three more the Council of Arles in AD 314. The Roman Empress Helena was, we believe, a Christian and a British Princess [see More 2]. Earlier still, King Lierwg (known to the Romans as Lucius or Luke) had corresponded with Eleutherius, Bishop of Rome, around AD 178-180, as Christian to Christian. All this is in the official Church records. There is also a record of there being archbishops in London from the second century AD [see More 1]. So Austin did not bring Christianity to Britain, though he did bring Roman Catholicism.
