 British bishops attended the Council of Arles in A.D. 314 and the Council of Rimini in 359.Communication with Gaul may be inferred from dedications to St. Martin at Whithorn and at Canterbury, from the mission of Victridius of Rouen in A.D. 396 and those of Germanus of Auxerre, with St. Lupus in 429 and with St. Severus in 447, directed against the Pelagianism of which the bishops of Britain stood accused.However much of Britain derived their religion from Irish missionsaries.
