 Bede's account of Eadbald's conversion states that it was Laurence, Justus' predecessor at Canterbury, who converted the King to Christianity, but the historian D. P. Kirby argues that the letter's reference to Eadbald makes it likely that it was Justus.Other historians, including Barbara Yorke and Henry Mayr-Harting, conclude that Bede's account is correct, and that Eadbald was converted by Laurence.Yorke argues that there were two kings of Kent during Eadbald's reign, Eadbald and Æthelwald, and that Æthelwald was the "Aduluald" referred to by Boniface.
