We had, back in the 1960s, a very weird case in Oklahoma City where an entire family was DFd for "pharma spiritism". They were seeing a Native American healer who gave them herbal tea as a cure, and made the mistake of telling people in the congregation how great it was.
Two of the servants got a real hard-case going about this, and confronted them. They would not back down, so they ended up being DFd under the technical term of "spiritism". Note - true "Satanic demonism" was never in question: this was really a sort of disagreement on a homeopathic medical practice.
It made no sense at all to many of the servants at the time (Marion Dunlap was one, he told me about this later) - but it still got done. The circuit servant was all for disfellowshipping them too, so that carried a lot of weight.
