Umm, the church puts you on a never-ending guilt trip. Nothing you ever do, nothing you ever think is good enough to please their God. We sin when we get up in the morning, we sin all day long, we sin when we go to bed at night. It is not sinful to be human and to think and feel things others don't think and feel.
It all boils down to brain chemicals working properly. If your brain chemicals are fully charged, you don't care if fairies fly over the altar during mass. You only care about those things when you are depressed and crabby.
