St. Augustine was an Italian missionary. He arrived in the Saxon part of Britain in AD 597 and made friends with the Saxon King of Kent. His people became Christians. The British Christians believed slightly different things to the Saxon Christians. There was a big argument about when Easter should be celebrated. Augustine met with the British bishops at Aust (in Gloucestershire), but was very rude to them! He said the British Christians were bad and should do what he told them. The British bishops told Augustine to go away. So he went back to the Saxon part of Britain. The British bishops ignored what he had said and carried on with Christianity in their own way. In AD 768, the British finally decided to change what they believed to the same as the Saxons.
