In 664, a council at Whitby decided to align the traditions of the Northumbrian Church with those of Rome and Constantinople.
In 634, monk Aidan established a monastery on the ‘holy island’ of Lindisfarne in Northumbria. Aidan taught King Oswiu’s chaplains the traditions of the monastery founded by Columba, an Irishman, on Iona in western Scotland; but Oswiu’s Queen came from Kent, and her chaplains kept the Roman ways brought by St Augustine to Canterbury. At last, Oswiu could stand the bickering no more.
