my position is similar to yours. I am a christian, and i believe God created me to live naked just like Adam and Eve did in the garden of Eden,before they committed the fist act of disobedience. I keep my nudism a secrete from Christian because most of them would not except the nudist life style. They like most of society that is over sexed my the media,can't separate sex from nudity.
A cording to the bible neither are sinful or shameful as long as they are practice is the way God institutionalized them.
The same thing could happen if a christian while at a nudist resort tell the wrong person they are a christian. The person who hates Christianity could falsely accuse the christian of some kind of offensive behavior and have them band from the resort.
So one has to use discretion when sharing information about one self.
