pretty self explanatory title, i have intrusive thoughts (not terribly, think God, but enough to cause me anxiety) and i was wondering how i should examine my thoughts so i can tell if they are intrusive and i have no responsibility for them, or i willingly thought of something.
for example, i was running today and listening to music that you could call dark and heavy, not satanic by any means, just heavy and in a minor key. anyways in the midst of this a thought popped into my head of me desecrating the Eucharist. i became frightened and immediately asked for forgiveness assuming that it was a scrupulous thought, however i couldnt help feeling that i had somehow willfully let the thought into my mind and so i feel somewhat guilty.
so my question is this: how do i judge my thoughts so i can tell what is sinful and what is not?
