The distinctive phrase, domino in domino dominorum, shared by the salutations in the prefatory letter of Bede's revised metrical Vita Cuthberti and in the letter sent by Hwaetbert with his former abbot Ceolfrith to Rome, reflects an unexpected historical connection among Bede's revision, Ceolfrith's departure and, more tentatively, the abdication of John of Beverley of the bishopric of York. While only Ceolfrith's journey has been dated to 716, I argue that Bede was revising his poem in anticipation of this event, but under the false assumption that it would be John of Beverley who would lead the party. The salutation, drawn from one of Augustine of Hippo's letters, supports this claim by identifying, after the opening phrase that would be appropriate for a bishop, John as a priest, a playful conjunction of terms used by Bede to call attention to the bishop of York's changing status. This opening, then, was in Bede's mind when the need for a letter from Hwaetbert to Pope Gregory II arose. Bede's revision and, probably, some discussion of John's retirement can be dated to 716.
