But the good King Oswald left a worthy successor in his brother Oswiu, as zealous a Christian and as vigorous a ruler as himself. Oswiu defeated Penda at the battle of the Winweed, and by slaying the slayer became the over-king of all England. He conquered the Picts between Forth and Tay, made the Welsh and the Cumbrians pay him tribute, and annexed northern Mercia, giving the rest of the kingdom over to Peada, Penda's son, only when he became a Christian. It was all over with the cause of heathenism when Penda fell, and the Mercians and their king bowed to the conquering faith, and listened to the preaching of Ceadda, one of the Northumbrian monks who had been taught by the Irish missionaries Aidan and Finan.
Dissensions of Irish and Roman clergy.—Council at Whitby, 664.
Mercia and Northumbria, therefore, owed their conversion to the disciples of Columba, and looked to the monastery of Iona as the source of their Christianity, while Kent and Wessex looked to Rome, from whence had come Augustine and Birinus. Unhappily there arose dissension between the clergy of the two churches, for the converts of the Irish monks thought that the South English paid too much deference to Rome, and differed from them on many small points of practice, such as the proper day for keeping Easter, and the way in which priests should cut their hair. King Oswiu was grievously vexed at these quarrels, and held a council at Whitby, or Streonshalch as it was then called, to hear both sides state their case before him. He made his decision in favour of the Roman observance, and many of the Irish clergy withdrew in consequence from his kingdom, rather than conform to the ways of their Roman brethren. This submission of the English to the Papal see was destined to lead to many evils in later generations, but at the time it was far the better alternative. If they had decided to adhere to the Irish connection, they would have stood aside from the rest of Western Christendom, and sundered themselves from the fellowship of Christian nations, and the civilizing influences of which Rome was then the centre (664).
Archbishop Theodore.—Unification of the Church in Britain.
The English Church, being thus united in communion with Rome, received as Archbishop of Canterbury a Greek monk named Theodore of Tarsus, whom Pope Vitalian recommended to them. It was this Theodore who first organized the Church of England into a united whole; down to his day the missionaries who worked in the different kingdoms had nothing to do with each other. But now all England was divided into bishoprics, which all paid obedience to the metropolitan see of Canterbury; and in each bishopric the countryside was furnished with clergy to work under the bishop. Some have said that Theodore cut up England into parishes, each served by a resident priest, but things had not advanced quite so far by his day. Under Theodore and his successors the bishops and clergy of all the kingdoms frequently met in councils and synods, so that England was united into a spiritual whole long before she gained political unity. It was first in these church meetings that Mercian, West Saxon, and Northumbrian learnt to meet as friends and equals, to work for the common good of them all.
Prosperity of the Church.—Winfrith.—Baeda-Alcuin.
The English Church was vigorous from the very first. Ere it had been a hundred years in existence it had begun to produce men of such wisdom and piety, that England was considered the most saintly land of Western Christendom. It sent out the missionaries who rescued Germany from heathenism—Willibrord, the apostle of Frisia ; Suidbert, who converted Hesse ; above all the great Winfrith (or Boniface), the first Archbishop of Mainz. This great man, the friend and adviser of the Frankish ruler Charles Martel, spread the gospel all over Central Germany, and organized a national church in the lands on the Main and Saal, where previously Woden and his fellows alone had been worshipped. He died a martyr among the heathen of the Frisian Marshes in 733.
Nor was the English Church less noted for its men of learning. Not only were they well versed in Latin, which was the common language of the clergy all over Europe, but some of them were skilled in Greek also, for the good Archbishop Theodore of Tarsus had instructed many in his native tongue. Among the old English scholars two deserve special mention: one is the Northumbrian Baeda (the Venerable Bede), a monk of Jarrow, who translated the Testament from Greek into English, and also wrote an ecclesiastical history of England which is our chief source for the knowledge of his times (d. 735); the second was another Northumbrian, Alcuin of York, whose knowledge was so celebrated all over Europe that the Emperor Charles the Great sent for him to Aachen, the Frankish capital, and made him his friend and tutor; for Charles ardently loved all manner of learning, and could find no one like Alcuin among his own people.
