I used to think that a Spiritualist was a person who believed in Spiritualism as described by the National Spiritualist Association of Churches (NSAC) in the US or possibly the Spiritualists National Union (SNU) in the UK.  Nothing more.

But I now see the term cropping up in areas I wouldn’t expect.  For example, in reference to a Sikh guru.  Or a domestic and international Strategy Consultant.  Or in an article about Yoga Spirituality, based in India.

“Spiritualist” doesn’t have the type of narrow and exclusive meaning like “Catholic” or “Muslim” have.  Spiritualism never claimed exclusivity or copyright or what-have-you on it.

Perhaps the first type of Spiritualism should be called Classic Spiritualism, just to differentiate it from the other uses of the term.  Classic Spiritualism seems to be more prevalent in the US, the UK, and Australia, than it is in other places.  So if you’re in the context of these countries, “Spiritualist” it’s likely to be Classic Spiritualism. Any other country, all bets are off.
