Can being a naturist be spiritual ?
I am in full agreement with your view of nudism/naturism.
Personally I feel more alive and part of the wonderful creation around me. I now accept the body I was given and appreciate all my fellow nudist friends irrespective of size, weight, colour, age etc. It is all wonderful.
Being a scout from age 11 gave me an insight into the natural world around me. Becoming a full time nudist was a further revelation.
There's a lot of conflict in the Bible regarding nudity and sexuality, and many have rejected Christianity as a result. There's even conflict if Christians can accept spirituality outside of their faith, at least there was in my evangelical church of origin which was anti-nudity. Since we came into the world naked, I think the answer is not if but how a naturist can be spiritual.
I enjoyed watching this youtube video on rethinking Christianity to be sex-positive.
