God has established within Christian culture and who borrow from Christian Culture a sense of propriety that is to a large degree recognised universaly in that culture.
How do we know this (i.e.: vague ideas about propriety) is from God as opposed to the natural development of cultural quirks?
In light of the above quote, how then do we explain the rise of social nudism in historically Christian areas of the world (e.g.: France, America, and most outstandingly, Germany)?
FKK has never been so prevalent in America as certain parts of Europe. I really think this may be due, in part, to the different cultural receptions of the Enlightenment, especially the conception of primordial man seen in the philosophical anthropology of Rousseau's Second Discourse, and its interpretation by readers as idealizing the wild, naked, pre-governmental noble savage, anticipating Romanticism.
In both cases, there was a recoiling from hierarchy and traditional culture, but in America it has largely been limited to a Lockean revolution with reference to the political order, certainly because of the national project of constructing a new one. Pre-social contract man in his natural state in Locke's philosophy does not look so bizarre; the natural law is there, including property, but everyone is individually troubled and burdened with its preservation and protection.
Popular anti-Catholic biases and deism aside, the sort of morally base revolutionary impulse in such a thing as French anti-clericalism has no analogue in the historical American character; Americans have never so much tried to destroy an old order as to create new one, preserving the mores and habits already in place.
Sorry for the detour and disorganization. My basic point is that FKK and "social nudity" are profoundly anti-Christian, products of a conscious abandonment of traditional and rational habits, done for the sake of liberation in utopian schemes to "immanentize the eschaton," to borrow a phrase from Voegelin. America, while by no means innocent, has experienced less drastic symptoms by appropriating the revolutionary impulse within a political framework, defining and limiting it.
