Pope St. Sergius I, letter to Abbot Ceolfrid, says that certain difficult questions have arisen, and he is in need of learned men to aid him in looking into them; and therefore he asks Ceolfrid to send him without delay “that religious servant of God, Bede (religiosum Dei famulum Bedam), a priest of your monastery.” (Source: Horace Kinder Mann, in his work “The Lives of the Popes of the Early Middle Ages”, Part I, pg. 84, pub. 1903)
