Scots which dwelt in the South of Ireland had long since, by the admonition of the Bishop of the Apostolic see, learned to observe Easter according to the canonical custom.(296)
On the arrival of the bishop, the king appointed him his episcopal see in the island of Lindisfarne,(297) as he desired. Which place, as the tide ebbs and flows, is twice a day enclosed by the waves of the sea like an island; and again, twice, when the beach is left dry, becomes contiguous with the land. The king also humbly and willingly in all things giving ear to his admonitions, industriously applied himself to build up and extend the Church of Christ in his kingdom; wherein, when the bishop, who was not perfectly skilled in the English tongue, preached the Gospel, it was a fair sight to see the king himself interpreting the Word of God to his ealdormen and thegns, for he had thoroughly learned the language of the Scots during his long banishment. From that time many came daily into Britain from the country of the Scots, and with great devotion preached the Word to those provinces of the English, over which King Oswald reigned, and those among them that had received priest’s orders,(298) administered the grace of Baptism to the believers. Churches were built in divers places; the people joyfully flocked together to hear the Word; lands and other property were given of the king’s bounty to found monasteries; English children, as well as their elders, were instructed by their Scottish teachers in study and the observance of monastic discipline. For most of those who came to preach were monks. Bishop Aidan was himself a monk, having been sent out from the island called Hii,(299) whereof the monastery was for a long time the chief of almost all those of the northern Scots,(300) and all those of the Picts, and had the direction of their people. That island belongs to Britain, being divided from it by a small arm of the sea, but had been long since given by the Picts, who inhabit those parts of Britain, to the Scottish monks, because they had received the faith of Christ through their preaching.
Chap. IV. When the nation of the Picts received the faith of Christ. [565 A.D.]
In the year of our Lord 565, when Justin, the younger, the successor of Justinian, obtained the government of the Roman empire, there came into Britain from Ireland a famous priest and abbot, marked as a monk by habit and manner of life, whose name was Columba,(301) to preach the word of God to the provinces of the northern Picts, who are separated from the southern parts belonging to that nation by steep and rugged mountains. For the southern Picts, who dwell on this side of those mountains, had, it is said, long before forsaken the errors of idolatry, and received the true faith by the preaching of Bishop Ninias,(302) a most reverend and holy man of the British nation, who had been regularly instructed at Rome in the faith and mysteries of the truth; whose episcopal see, named after St. Martin the bishop, and famous for a church dedicated to him (wherein Ninias himself and many other saints rest in the body), is now in the possession of the English nation. The place belongs to the province of the Bernicians, and is commonly called the White House,(303) because he there built a church of stone, which was not usual among the Britons.
