Some of these thoughts might be memory too. For example, if you once looked a crucifix and thought about doing something to it, you might just be repeating that experience because it is troubling to you. Do you have any real desire to do it? If you don’t, then it just a mental thing that occurs in your intellect. You might not be able to control your imagination/memory but you can teach yourself that these thoughts are not very important. I wouldn’t spend time trying to analyze them beyond determining if the desire to do these things are real or imagined. I think if the desire were real, you wouldn’t frame the situation as “Hey, I am having thoughts, what can I do?”. You would say “Hey, I truly hate Jesus and his Mother, is there any reason to care about them?”
OCD is obsessive-compulsive disorder. Perople who have this are plagued by obsessive thoughts that they can’t get rid of and that cause much anxiety, and often have to carry out compulsive rituals in order to ease their anxiety. For example somebody might obsessively worry about having left the door open, even if it was just a minor minoreven after they had gone back twice already to check and found it closed, or somebody might worry about having germs on their hands even after having washed them, thus having to wash them again and again… Similarly, somebody with scruples (scrupulosity can be seen as a form of OCD) might worry about having committed a grave sin even if it was just a minor minor thing (like, having a quick, unintentional angry thought), and as a compulsion this person might have to call a priest, but maybe if the priest reassueres him or her, andother worry might come up (I have been there, and not just one time).
Taking it from there… somebody who is scrupulous and has an intrusive thought, an unintentional stupid little thought about something, as in that example about lokking at a cross… might then worry about it so much that he/she can’t get the thought out of their minds. And fear thinking it so much that they become afraid to even look at any religious picture, for fear the thought might come again… and if they do look at one, the fear of thinking the thought is present from the beginning and thus the thought may just come automatically, because by fearing it of course we somehow already THINK it… but not in an intentional way.
So i would be careful about saying that we have complete control about what we think… such a person must learn to realize that these thoughts are NOT intentional, thus lose the fear of them… I am not sure if I explained that well…:shrug:
See a doctor, sometimes these thoughts can be overcome through talking therapies without any need to resort to medication. While it is true and accepted by many that evil tries to corrupt souls with methods like this by overloading our senses what better way to show the devil how weak and pathetic a creature he is than by asking for strength through prayer and simple talking.
