Now I've seen everything.

I recently discovered, quite by accident, that there is a Christian nudist organization. The Natura Christian Fellowship claims to have 32,000 members. It started 65 years ago as a Quaker offshoot but has since attracted Catholics, Southern Baptists, Lutherans, Methodists, Mormons, Jehovah’s Witnesses, etc. As a result, Natura no longer identifies itself as Quaker. The group draws its inspiration from Isaiah 20:2, where the prophet walked around naked for three years. They also claim to be very devout and "family-oriented". They do not seem to have a website, which is probably a good thing. Other details are scanty.
