 It is not known whether Eorpwald was baptised in East Anglia, Northumbria or Kent, but it is very likely that Edwin, now the senior ruler, was present as his sponsor.Higham suggests that because of the lack of proper facilities in East Anglia, it is likely that he was baptised by Paulinus at Edwin's centre of authority in Northumbria.The manner of Eorpwald's conversion indicated that he was a subordinate king and that Edwin was his overlord.
