The Church of England in its existing form owes its organisation to a Greek monk. In 667, Oswiu of Northumbria and Ecgberht of Kent, in order to bring their dominions into closer connection with Rome, united in sending Wigheard the priest to the pope, that he might be hallowed Archbishop of Canterbury. No Englishman had yet held that office, and the choice may be regarded as a symptom of growth in the native Church. But Wigheard died at Rome, and the pope seized the opportunity to consecrate an archbishop in the Roman interest. His choice fell upon one Theodore, a monk of Tarsus in Cilicia, who was in the orders of the Eastern church. The pope was particular, however, that Theodore should not "introduce anything contrary to the verity of the faith into the Church over which he was to preside." Theodore accepted Roman orders and the Roman tonsure, and set out for his province, where he arrived after various adventures on the way. His re-organisation of the young Church was thorough and systematic. Originally England had been divided into seven great dioceses, corresponding to the principal kingdoms (save only still heathen Sussex), and having their sees in their chief towns–East and West Kent, at Canterbury and Rochester; Essex, at London; Wessex, at Dorchester or Winchester; Northumbria, at York; East Anglia, at Dunwich; and Mercia, at Lichfield. The Scottish bishopric of Lindisfarne coincided with Bernicia. Theodore divided these great dioceses into smaller ones; East Anglia had two, for its north and south folk, at Elmham and Dunwich; Bernicia was divided between Lindisfarne and Hexham; Lincolnshire had its see placed at Sidnacester; and the sub-kingdoms of Mercia were also made into dioceses, the Huiccii having their bishop-stool at Worcester; the Hecans, at Hereford; and the Middle English, at Leicester. But Theodore's great work was the establishment of the national synod, in which all the clergy of the various English kingdoms met together as a single people. This was the first step ever taken towards the unification of England; and the ecclesiastical unity thus preceded and paved the way for the political unity which was to follow it. Theodore's organisation brought the whole Church into connection with Rome. The bishops owing their orders to the Scots conformed or withdrew, and henceforward Rome held undisputed sway. Before Theodore, all the archbishops of Canterbury and all the bishops of the southern kingdoms had been Roman missionaries; those of the north had been Scots or in Scottish orders. After Theodore they were all Englishmen in Roman orders. The native church became thenceforward wholly self-supporting.
