Our club has a really nice outside chapel venue. There are a few ministers that reside there and hold services for Easter, Christmas and there have been some weddings and vow renewals there. The only drawback ... it's up at the top of a steep stairway made of cement block. Tough trek for elder folk.
It would be interesting to see how a nudist congregation fared under the laws. It wouldn't be a private club and so laws regarding public nudity probably could be enforced, on the other hand after years of asserting that religion does not give an out from laws of general application, conservatives are arguing just that. (Of course, it's always the question of whether it's their religion or someone else's.)
If the Supreme Court finds for the bakery in Masterpiece Cakeshop and thus carves a big religious exemption to anti-discrimination law, I see no reason not to create a religion where nudity is required.
God made Adam and Eve Nude and they lived in the Garden Of Eden that way, so why would God or Jesus have any objections to people praying, worshiping and doing Bible study that way. God (through the love making of our parents or just the act of two people) created our bodies and us. So A church for Nudists is A-OK. People who think this is 'dirty' somehow, are essentially saying 'God creates filth in the human form', which of course God does not. It's the certain things one may do to or wit their bodies or someone else's that makes it 'filth'. God does not care if you're wearing your nice $300.00 Sunday suit or your birthday suit, as long as you are honest in faith.
