My definition would have to be based on the terms themselves. Nudist to me says just nude, no qualifications. It could be non sexual or sexual based, it could be private/secret or exhibition style. Naturist would indicate in harmony with nature, which is non sexual except in appropriate situations (with the wife/husband in private) It indicates an overall lifestyle in harmony with nature, not just going naked as God intended when He created all nature. Not necessarily applied to just those who have arrived, but also to those who desire to go there and do that even if we haven't made a lot of progress or just getting started. The ultimate naturist lives with nature without harming nature, being the caretaker we were instructed to be originally, as much as possible given the corrupted fallen conditions. I see it kind of hard for someone to pursue a fully naturist lifestyle in a city, where the surroundings are very anti-nature. Someplace where one can grow their food, or most of it, and live simply with minimal use of scarce resources is more along the line of naturism, while doing it naked as possible is just the dressing. Icing on the cake.
