Thus the good fruits of the mission of Augustine were completely lost. An interval occurs, and then Sigebert the Good, on a visit to King Oswy of Northumbria, was converted by the reasoning of his host, and baptised by Bishop Finan of Lindisfarne. Finan had no connection with Rome, but belonged to that remarkable body who traced their origin to Ireland and Iona. Sigebert took south with him two brothers, English by race, recommended by Finan, of whom one was CEDD; a third brother was the more famous Chad. The work of re-planting was at once set about with the help of Sigebert's example and protection. Up and down the province they went, and gained so many converts that Finan felt justified in consecrating Cedd bishop of the East Saxons. The new bishop now employed much of his time in training converts, natives of the province, for the priesthood, both at Ythancester, near Tillingham, and at Tilbury.[6] He acted as interpreter at the Whitby Conference, where he was won over to the continental method of reckoning Easter, and died shortly after of the plague (664). A later visitation of the pestilence is assigned as a cause of half of the diocese relapsing, while the other half, governed by Sebbe, remained faithful. King Wulfhere of Mercia--the then overlord--sent his own bishop Jaruman with a number of clergy, who effected a complete restoration. Mellitus, Cedd, Sabert, Sigebert, and Sebbe (said to have been buried at St. Paul's) now appear in the transept windows as founders of English Christianity. Thus we find, after various vicissitudes and relapses, the Christian religion planted in the East Saxon province before the end of the seventh century. The succeeding centuries must be rapidly passed over. A staff of clergy was formed who came to be called canons; other endowments by degrees added; the services at St. Paul's maintained as a model for the diocese; parish churches and monasteries built. We must even pass over Bishop Erkenwald, the hero of so many stories, and whose shrine was the most popular in Old St. Paul's. In 962, just after Dunstan had left the bishopric for Canterbury, St. Paul's was burnt, and the same year rebuilt. Both before and after this London suffered from the ravages of the Danes. The Primate Elfege, the victim of a drunken rabble, was buried at St. Paul's (1014), as was Ethelred the Unready (1017), and nearly fifty years later Edward the outlaw, the representative of the house of Cerdic and of Alfred.
