 Only the last would support the conjecture that it aimed to support the Gregorian mission to the Anglo-Saxons led by Augustine of Canterbury, who encountered great difficulty with the native British Christians, as at the Synod of Chester.Indeed, the Celtic Christians invoked the antiquity of their church to generally submission to Canterbury until the Norman conquest, but no arguments invoking the mission to Lucius appear to have been made by either side during the synods among the Welsh and Saxon bishops.The first Englishman to mention the story was Bede and he seems to have taken it, not from native texts or traditions, but from "The Book of the Popes".
