Public nudity has been questionable in many societies and many people feel uncomfortable around nudists. However, the concept of being clothes-free is more about having your freedom and to be comfortable with your body.
If people would bother to actually read the Bible, they’d see that nudity is referenced in the context of poverty, simplicity, and as a simple observation of one’s manner of dress while doing things that were sometimes good and sometimes bad. Those things weren’t bad or good because they were naked.
They were simply naked at the time they were doing them. That’s the way nudity has been thought of for almost all of history until the last century or two in today’s perverted cultures.
Nudism/naturism isn’t counter to Christianity. Rather is complementary to it for those of us who practice both.
