Saint Felix of Burgundy, also known as Felix of Dunwich is a saint widely credited as the man who introduced Christianity to East Anglia in Eastern England.

He arrived in England sometime around AD 615 in the hamlet of Babingley, Norfolk via the River Babingley and made his way to Canterbury where he was ordained as a Bishop about 630 or 631[2] by the Archbishop of Canterbury, Honorius, at the request of King Sigebert of East Anglia.[3]
He is recorded by Bede as having formed his episcopal see at Dommoc which is widely taken to mean Dunwich on the Suffolk coast, although other historians have suggested an alternative site at Walton, Suffolk near Felixstowe, where a church and priory were dedicated to him by Roger Bigod in 1105. Soon afterwards, he established a church and school at Domnoc and also founded the abbey of Soham in Cambridgeshire. He was widely seen as being something of a bridge-builder between the Roman and Celtic traditions of Christianity. St Felix is said to have died on 8 March[1] 647 or 648,[2] later celebrated as his feast day.[1] He was bishop for seventeen years.[4]
His body was interred at Soham Abbey but this was pillaged by the Vikings in 869 and his tomb desecrated. During the reign of Cnut his remains were again moved to Ramsey Abbey on the Fens. He was succeeded as Bishop by Thomas, a Fenman.
