here is spiritual OCD among Catholics as well. In fact when I saw the title of this article, I thought that was what it would be about. It's called scrupulosity, and I've known several folks who suffer or have suffered from it. Many years ago, I started to become borderline scrupulous myself, mainly due to the influence of a close friend who was severely scrupulous
You seem to be using "scrupulous" as a technical term, a usage unfamiliar to this protestant Christian. Care to clarify what it means in a C. of R. context?
Scrupulosity is indeed a term of art for Catholics. "An unfounded apprehension and consequently unwarranted fear that something is a sin which, as a matter of fact, is not." (from the Catholic Encyclopedia).
It really does resemble OCD very closely. Much as a sufferer from OCD may "have" to keep returning to the house to make sure the stove's turned off (even though he knows it is because he's already checked it 2-3 times), someone suffering from scrupulosity "has" to confess frequently because he "knows" that (1) he is committing sins all the time and (2) his last confession may not have been "good". There may also be an element of spiritual pride (although it's probably just the compulsive aspect of OCD), because the scrupulous person trusts his own feelings or beliefs over the assurances of the confessor that he has made a good confession, etc.
Those of us who are just learning how to examine our consciences on a regular basis, to recognize when a sin may be mortal or when an accumulation of venial sins is becoming dangerous, and to make a good confession, are getting a lot of guidance from our priests and are unlikely to mistrust them. But I am a bit OCD myself, and I can see how this could easily become a problem if I started second-guessing my confessions in the same way I second-guess whether I left the porch light on!
