Editing Synod of Whitby (section)

==Outcome==
The Synod of Whitby established the supposed Roman practice as the norm in Northumbria, and thus "brought the [[Northumbria]]n church into the mainstream of Roman culture."<ref>Colgrave, ''Earliest Life of Gregory the Great'', p. 9.</ref> The episcopal seat of Northumbria was transferred from [[Lindisfarne]] to [[York]]. Wilfrid, chief advocate for the Roman position, later became Bishop of Northumbria, while Colmán and the Ionan supporters who did not change their practices withdrew to Iona. Colmán was allowed to take some relics of Aidan, who had been central in establishing Christianity of the Ionan tradition in Northumbria, with him back to Iona. To replace the departing ecclesiastics, Oswiu chose mostly Irishmen who were from the parts of Ireland that kept the Roman Easter (as most of Ireland had done for some time by the 660s).
