(521-597) Confessor, apostle of the Picts, Abbot of Iona, born Gartan, Ireland; died Iona, Scotland. He entered the monastic life at Moville, studied under Saint Finnian, and was later ordained by Bishop Etchen of Glonfad. In 563 he left Ireland; journeyed to Scotland, and founded a large monastery on the island of Iona. He made numerous conversions among the Picts, having won over their king, Brude. During his exile he returned twice to Ireland, and was prominent at the Council of Drumceat, 575. The Benedictine rule has, since Columba’s time, replaced his monastic rule, which was prevalent in Germany, Gaul, Britain, and northern Italy. Besides his missionary work, he is said to have written 300 books. Patron of Ireland and Scotland. His remains are interred at Downpatrick with those of Saint Patrick and Saint Brigid. Feast, 9 June.
