ok, valid scriptures, but how does that help in the 1/3 part discussion? Knowing there are spirits and bodied beings is well, ok, not sure anyone has disagreed with that. but, how does that apply to this case?
BTW not sure any normal ranking spirit (good or evil) can be an angel of light, seems like a Satan-level type being?
Interesting there are few real meaty scriptures that talk about spirits taking over or mixing with bodies, outside the OT and JS's may be true but odd. When was the last time he or anyone else we know of had to offer a hand to find out what kind of being we were with? Not that I disagree, but never heard of practical use for that one. Frankly, it would be hard to imagine not knowing if a being is solid or not, IMO. I've never seen one, but have had experiences. And a visitation from an angel would trigger much more than wondering what kind of being it was. In fact, almost all (believable) instances seem to be in vision, like Joseph's D&C 76. It doesn't help to do this vision, i.e. seeing Jesus on a golden platform at his throne. It only helps when a being shows up in the woods and starts chatting you up about godly things. Just putting it out there that the reality of some of these (most of these) talks of interacting with spirits from modern scripture seem to be there to make us calmer and unworried about interacting with the spiritual and to provide a bit of balance if we, were for some reason to be visited by an unearthly being.
Although, seems like the message might also be a key to solving the reality of it.
