“ Augustine, first Archbishop of Canterbury, to the time of Archbishop Lanfranc of blessed memory, there was no archdeacon in the city and diocese of Canterbury. But from the time of Archbishop Theodore, who was sixth from St. Augustine, to the time of the aforesaid Lanfranc, there was in the church of St. Martin's, a suburb of Canterbury, a bishop ordained by Theodore, under the authority of Pope Vitalian, who in all [35] the city and diocese of Canterbury undertook duties in the place of the archbishop, conferring holy orders, consecrating churches, and confirming children during his absence. ”
