Mission and Foundations
Moluag's labors centered on the conversion of the Picts of Scotland. After establishing himself on Lismore around 562, he and his monks moved across western Scotland, founding a number of further churches; dedications to him are recorded on Lewis, Skye, Raasay, Tiree, and Mull, in Morvern and Inveraray, and as far afield as the Isle of Man.
Beyond Lismore, his two other principal centres were Rosemarkie, in Pictish territory on the Moray Firth, and Mortlach in Banffshire. From these houses daughter churches spread into Aberdeenshire and Perthshire. His three great foundations later became seats of the dioceses of the Isles, Ross, and Aberdeen, a measure of the lasting institutional weight of his mission.
Tradition counts Moluag among a group of Irish priests said to have been foretold by Saint Patrick, and links his monastic formation to the Irish tradition of Bangor associated with Saint Comgall. The sources hedge these connections, and his own surviving record is sparse, but they place him firmly within the network of Irish monasticism that reached into Scotland in the sixth century.
