St. Aidan studied under St. Senan, and he became a monk at Iona in about the year 630. His obvious virtues caused him to be selected as first Bishop of Lindisfarne in 635, and in time he became known as the "apostle of Northumbria." St. Bede spoke highly of the spiritual care given by St. Aidan to his people. Oswald, the king of Northumbria, and who had studied in Ireland, was a close friend of St. Aidan, and gave great support to his work. St. Aidan died at Bamborough on 31 August 651, and his remains were taken to Lindisfarne. St. Bede writes that "he was a pontiff inspired with a passionate love of virtue, but at the same time full of a surpassing mildness and gentleness."
O loving God, who didst call thy servant St. Aidan of Lindisfarne from the peace of a cloister to reestablish the Christian mission in northern England, and didst endow him with gentleness, simplicity, and strength: Grant, we beseech thee, that we, following his example, may use what thou hast given us for the relief of human need, and may persevere in commending the saving Gospel of our Redeemer Jesus Christ; who liveth and reigneth with thee and the Holy Spirit, one God, for ever and ever. Amen.
