Augustine’s mission in 597 converted Kent; but it had only temporary success in Essex, which reverted to heathenism in 616. A mission sent under Bishop Paulinus from Kent to Northumbria in 627 converted King Edwin and many of his subjects in Northumbria and Lindsey. It received a setback in 632 when Edwin was killed and Paulinus withdrew to Kent. About 630 Archbishop Honorius of Canterbury sent a Burgundian, Felix, to convert East Anglia, and the East Anglian church thenceforth remained faithful to Canterbury. Soon after, the West Saxons were converted by Birinus, who came from Rome. Meanwhile, King Oswald began to restore Christianity in Northumbria, bringing Celtic missionaries from Iona. And it was the Celtic church that began in 653 to spread the faith among the Middle Angles, the Mercians, and the peoples of the Severn valley; it also won back Essex.
At first there was little friction between the Roman and Celtic missions. Oswald of Northumbria joined with Cynegils of Wessex in giving Dorchester-on-Thames as seat for Birinus’ bishopric; the Irishmen Maildubh in Wessex and Fursey in East Anglia worked in areas converted by the Roman church; and James the Deacon continued Paulinus’ work in Northumbria. Later, however, differences in usage—especially in the calculation of the date of Easter—caused controversy, which was settled in favour of the Roman party at the Synod of Whitby in 664. The adherents of Celtic usage either conformed or withdrew, and advocates of Roman practice became active in the north, the Midlands, and Essex. Theodore of Tarsus (arrived 669), the first Roman archbishop to be acknowledged all over England, was active in establishing a proper diocesan system, whereas in the Celtic church bishops tended to move freely without fixed sees and settled boundaries; he held the first synod of the English church at Hertford in 672, and this forbade a bishop to interfere in another’s diocese or any priest to move into another diocese without his bishop’s permission. Sussex and the Isle of Wight—the last outposts of heathenism—were converted by Bishop Wilfrid and his followers from 681 to 687 and thenceforth followed Roman usages.
The Anglo-Saxons attributed their conversion to Pope Gregory I, “the Apostle of the English,” who had sent Augustine. This may seem less than fair to the Celtic mission. The Celtic church made a great impression by its asceticism, fervour, and simplicity, and it had a lasting influence on scholarship. Yet the period of Celtic dominance was only 30 years. The decision at Whitby made possible a form of organization better fitted for permanent needs than the looser system of the Celtic church.
The golden age of Bede
Within a century of Augustine’s landing, England was in the forefront of scholarship. This high standard arose from a combination of influences: that from Ireland, which had escaped the decay caused elsewhere by the barbarian invasions, and that from the Mediterranean, which reached England mainly through Archbishop Theodore and his companion, the abbot Adrian. Under Theodore and Adrian, Canterbury became a famous school, and men trained there took their learning to other parts of England. One of these men was Aldhelm, who had been a pupil of Maildubh (the Irish founder of Malmesbury); under Aldhelm, Malmesbury became an influential centre of learning. Aldhelm’s own works, in Latin verse and prose, reveal a familiarity with many Latin authors; his writings became popular among admirers of the ornate and artificial style he had learned from his Celtic teachers. Before long a liberal education could be had at such other West Saxon monasteries as Nursling and Wimborne.
The finest centre of scholarship was Northumbria. There Celtic and classical influences met: missionaries brought books from Ireland, and many Englishmen went to Ireland to study. Other Northumbrians went abroad, especially to Rome; among them was Benedict Biscop. Benedict returned from Rome with Theodore (668–669), spent some time in Canterbury, and then brought the learning acquired there to Northumbria. He founded the monasteries at Wearmouth (674) and Jarrow (682), where Bede spent his life. Benedict and Ceolfrith, abbot of Jarrow, brought books from the Continent and assembled the fine library that was available to Bede.
Bede (c. 672–735) is remembered as a great historian whose work never lost its value; but he was also a theologian regarded throughout the Middle Ages as second only to the Church Fathers. Nonetheless, even though he was outstanding, he did not work in isolation. Other Northumbrian houses—Lindisfarne, Whitby, and Ripon—produced saints’ lives, and Bede was in touch with many learned men, not only in Northumbria; there are also signs of scholarly activity in London and in East Anglia.
