There is so much good advice in this thread, and since I haven’t been coming in lately, I have to assume it’s Providence.
I suffer severe scrupulosity - and have for years. I won’t detail but OP’s problems are similar to mine. I despise having them. I am fearful of whether or not they were entertained.
But for those who felt this shouldn’t be addressed here - but rather with priest / OCD professionals - please - you have no idea for those suffering with this - how much it helps to read and discuss it - realizing one is not alone in this suffering. I would not compare myself to the saints who suffered temptations. I just know scrupulosity and/or OCD is ruining my spiritual life, and I need God. But I also need to know/discuss it, if there are others suffering the same.
I think that it’s perfectly OK to discuss it. But I think that you will need an actual firm Confessor to be cured of it. Mine was just so strong and firm about it that he completely cured me. For me it was so bad that if some throught or inclination entered my mind even for a split second I would not go to Holy Communion just in case I may have committed a mortal sin by a momentary consent.
I think that some spiritual writings which teach that you can commit a mortal sin in a moment of consent unwittingly contribute to scrupulosity. While that’s certainly possible, the rule given by the best writers on spiritual direction insist that if a person is scrupulous, then the criteria to be applied is that if the scrupulous person is not ABSOLUTELY SURE that he or she committed a mortal sin, it’s highly unlikely that one was committed. In other words, if you’re scrupulous, you would darn well know when you committed a mortal sin and you wouldn’t be worried. You’d simply know that you had to go confess it before going to Holy Communion.
One of the things I try to do if I’m feeling the inclination to be scrupulous is that if I’m not absolutely sure I committed a serious sin I go to Holy Communion as soon as possible, knowing that if I had somehow lapsed that Our Lord would restore me to His Grace in Holy Communion. Now, mind you, this is NOT for situations where you know you’ve committed a mortal sin. It’s based on the teaching of St. Thomas Aquinas. And St. Alphonsus Liguori taught probabilism, allowing you to act on any reasonably probable conclusion. So if in my mind there’s a reasonable probability that I did not sin, then I act as if I did not sin.
Quite the opposite for lax consciences though. For a lax conscience, if that person is not sure about whether he sinned, it’s probable that he did sin. I was actually even tormented for a time with thoughts that I really had a lax conscience–for otherwise I would realize the myriad mortal sins I was committing every day.
You really need to have a good, strong firm confessor who will whip you into shape as he did for me.
Oh, and scrupulosity often inflicts introspective melancholic people. What happens is that the person confuses the MOVEMENTS of the lower faculties, the sensible parts of the soul, with movements of the WILL. Yes, the mind might be drawn towards something, even appear to move towards it, but the will does not accept it. So it might involve getting a feel for when the activity of the will has been engaged vs. when the activity of the lower faculties have “moved”. If you’re scrupulous and you’re not sure whether you consented, then you did not consent. That’s a pretty hard fast rule. Then force yourself to go to Holy Communion and trust God’s Mercy. In so doing, you’ll gradually understand the distinction between the activity of the will and the (involuntary) movements of those lower faculties.
God loves you more than you love yourself and is not just standing there waiting for you to make a mistake so that He can punish you. Our Lord’s Sacred Heart has tremendous compassion for you in your torments of scrupulosity and wants to lift that burden onto Himself, just as He took your very sins on Himself. Just give them to His Heart and ask Him to take them from you. Give them to Him as a gift and let them go, and lose yourself in His Sacred Heart. He will not let you perish.
These are just some of the things I think about when the devil attacks me with inclinations towards scrupulosity.
