It's not.
The book is a delightful combination.
If you can look past the occasional references to praying to the saints, you find humor and pretty decent theology.
Imagine a combination of Martin Luther, Matt Harrison, John Kleinig, and Peter Bender -- on topics of vocation and joy and marriage and contentment and suffering and serving-the-neighbor (albeit a bit short on the Gospel). Stir in a hefty amount of humor similar to Erma Bombeck's (yes!!). Sprinkle lightly with some Roman Catholic perspective.
It's a very quick read.
