Bede. 676. In the year of our Lord's incarnation 676, when Ethelred, king of the Mercians, ravaged Kent with a powerful army, and profaned churches and monasteries, without regard to religion, or the fear of God, he among the rest destroyed the city of Rochester [Map]; Putta, who was bishop, was absent at that time, but when he understood that his church was ravaged, and all things taken away, he went to Sexwulf, bishop of the Mercians, and having received of him a certain church, and a small spot of land, ended his days there in peace; in no way endeavouring to restore his bishopric, because (as has been said above) he was more industrious in spiritual than in worldly affairs; serving God only in that church, and going wherever he was desired, to teach church music. Theodore (age 74) consecrated Cuichelm bishop of Rochester in his stead; but he, not long after, departing from his bishopric for want of necessaries, and withdrawing to other parts, Gebmund was substituted in his place.
In 678 Bishop Gedmund of Rochester was consecrated Bishop of Rochester.
Bede. Bertwald succeeded Theodore in the archbishopric, being abbot of the monastery called Racuulfe [Map], which stands at the northern mouth of the river Genlade. He was a man learned in the Scriptures, and perfectly instructed in ecclesiastical and monastic teaching, yet in no wise to be compared to his predecessor. He was chosen bishop in the year of our Lord 692, on the first day of July, when Wictred (age 23) and Suaebhard were kings in Kent; but he was ordained the next year, on Sunday the 29th of June, by Godwin, metropolitan bishop of Gaul, and was enthroned on Sunday the 31st of August. Among the many bishops whom he ordained was Tobias, a man instructed in the Latin, Greek, and Saxon tongues, and otherwise of manifold learning, whom he consecrated in the stead of Gedmund, bishop of the Church of Rochester, who had died.
Around 710 Bishop Gedmund of Rochester died.
