QUESTION: I have horrible fleeting thoughts against God, Jesus, the Holy Mother, and the Holy Spirit– of cursing and blasphemy. It makes me very anxious and I have no peace. What can I do?
I would recommend that you speak with your local priest. There are too many details not available to me: (1) your age and state of life; (2) the culture and influences to which you are exposed; (3) the level of your religiosity; (4) life experiences and possible trauma; (5) your health and mental stability; and (6) the possibility of spiritual oppression or obsession.
We are constantly afflicted with fleeting bad thoughts and urges but we can redirect our attention and quickly dismiss them. If they are not directly intended and do not reflect our core preoccupation then I would just quickly disregard negative thoughts and images as insignificant. Scrupulosity about them gives them a certain negative hold upon us.
