O'Loughlin examines the theological framework within which St. Patrick presented his experiences and considers how the Celtic lands of Ireland and Wales developed a distinctive view of sin, reconciliation, and Christian law that they later exported to the rest of western Christianity.
Mr. O'Loughlin had a lot of interesting things to say. I didn't agree with all of it by any means, but enjoyed the book overall. It was a bit dry, but what can you expect from an academic work? ha!
