Peada, son of Penda, King of Mercia, being appointed by his father King of the Midland English, by which name Bede distinguished the inhabitants of Leicestershire, and part of Lincolnshire and Derbyshire, from the rest of the Mercians; the young king visited Oswy, King of Northumbria, at Atwell, or Walton, was baptized along with several of his nobles, by Bishop Finan, and was provided by Oswy with two priests to instruct his people in Christianity. One of these was S. Cedd, who had been trained in the monastery of Lindisfarne. "When these two," says Bede, "travelling to all parts of that country, had gathered a numerous church to the Lord, it happened that Cedd returned home, and came to the church of Lindisfarne to confer with Bishop Finan; who, finding how successful he had been in the work of the Gospel, made him Bishop of the Church of the East Saxons, calling to him two other bishops, to assist at the ordination. Cedd, having received the episcopal dignity, returned to his province, and pursuing the work he had begun, with more ample authority, built churches in several places, ordaining priests and deacons to assist him in the work of faith, and the ministry of baptizing, especially in the city which, in the language of the Saxons, is called Ithancester,[31] as also in that named Tilabury (Tilbury); the first of which places is on the bank of the Pante, the other on the bank of the Thames; where, gathering a flock of servants of Christ, he taught them to observe the discipline of regular life, as far as those rude people were then capable. "Whilst the doctrine of everlasting life was thus, for a considerable time, making progress, to the joy of the King and of all the people, it happened that the King, at the instigation of the enemy of all good men, was murdered by his own kindred. The same man of God, whilst he was bishop among the East Saxons, was wont also to visit, at intervals, his own country, Northumberland, to make exhortations. Ethelwald, the son of King Oswald, who reigned over the Deiri, finding him a holy, wise, and good man, desired him to accept some land to build a monastery, to which the King himself might frequently resort, to offer his prayers and hear the word, and be buried in it when he died; for he believed that he should receive much benefit by the prayers of those who were to serve God in that place. The King had before with him a brother of the same bishop, called Celin, a man no less devoted to God; who, being a priest, was wont to administer to him the word and the Sacraments, by whose means he chiefly came to know and love the bishop.
