I’m not sure. My family eats from IHOP all the time. Nothing seems to happen. We also eat from Popeyes, KFC, and the Cheesecake Factory. Nothing seems to happen.
I brought this subject up because I heard this argument a few years ago. I don’t believe that demons stick to you if you grab a falafel or such from non Christian owned places but apparently some self proclaimed demonologists do.
We used to call it Montezuma’s Revenge. Thunder down under.
No, I’ve never heard of demons attached to food, but when I was in Haiti I saw demonic activity all around me. There are videos circulating of Haitians sucking the blood out of live cats-- taking their life-blood in ritual fashion for some sort of power they believe they are taking in. Pure demonism.
