Has an atheist, an agnostic, a naturalist or anyone lacking a belief in the supernatural for that matter ever been demon possessed or had a demonic experience of any kind? Is this even possible to begin with (theoretically speaking)? My personal opinion would be that this should be possible in principle: there is no middle ground, a soul either belongs to God or Satan. Therefore, if an atheist or agnostic openly denies or rejects the existence of God, their soul cannot belong to God (because they don't have Jesus Christ as their Lord and Savior), and since there are not more options, it follows that their soul must belong to Satan. And if they belong to Satan, I would imagine that there should be demonic spirits assigned to each atheist or agnostic, and it shouldn't be too far-fetched to think that these spirits might decide to make their presence more obvious if they are compelled or under pressure to do so (e.g. I'm picturing in my head a hypothetical scene where a spirit-filled missionary confronts an atheist and the demons inside the atheist suddenly begin to manifest, etc.).
Has this ever happened? Does any denomination have records of performing exorcisms on atheists?
