This bishop was also styled Abbot of Dunkeld, perhaps holding jurisdiction, formerly enjoyed by Iona, over the other Columban monasteries in Scotland.

The new bishopric appears to have included a great part of what afterwards became the Diocese of Argyll, and retained its jurisdiction over various churches representing old Columban foundations.

Despite the Reformation and the hostility of the new Church of Scotland to bishops, episcopacy was not finally abolished until 1689, although there had been a temporary abolition from 1638 until the beginning of the 1660s.

The new Roman Catholic Diocese of Dunkeld is one of the suffragan sees of the archiepiscopal province of St. Andrews and Edinburgh, and includes the counties of Perth, Angus, Clackmannan, Kinross, and the northern part of Fife.

The diocesan cathedral, now dedicated to Saint Andrew rather than Columba, is located in Dundee, the residence of the great majority of the Catholics of the modern diocese.
