This sounds like a Police album but in fact scrupulosity is “a debilitating form of obsessive-compulsive disorder which takes the form of excessively fastidious religious observance, often in completely arbitrary ways, and fear of not being sufficiently devout or virtuous.”
Fortunately, drugs such as Zoloft and Paxil can be used to treat scrupulosity. I wonder how many potential saints the world loses every year to modern psychopharmacology.
