Byzantine Saints: Saint Aidan, Bishop of Lindesfarne (31 August)

About this sermon

St. Aidan of Lindisfarne was an Irish monk, missionary bishop, and Apostle of Northumbria whose humility, patience, and generosity helped restore Christianity across northern England. Formed at St. Columba’s monastery on Iona, Aidan was chosen for the Northumbrian mission after an earlier bishop failed through excessive severity. Aidan explained that an unformed people must first be fed with spiritual milk rather than solid food. His wisdom revealed the patience required for genuine evangelization. Consecrated bishop, Aidan established his episcopal see and monastery on Lindisfarne in 635. Because he did not speak English, King St. Oswald—who had learned Gaelic during exile on Iona—personally interpreted his preaching. Bishop and king thus labored together for the conversion of Northumbria. St. Bede praised Aidan’s humility, prayer, fasting, detachment, and care for the poor. He traveled largely on foot, founded missions, and distributed gifts from kings and nobles to those in need. When King Oswin gave him a horse, Aidan gave it to a beggar. Asked why he surrendered such a royal gift, the bishop replied: “Is that foal of a mare dearer to you than the Son of God?” Aidan died at Bamburgh on August 31, 651. At that hour, the young St. Cuthbert saw angels carrying a soul to Heaven in a sphere of fire—a vision that helped inspire his own religious vocation. This account also examines St. Aidan’s relics and the later suppression of Celtic customs following the Synod of Whitby.
