Some sage advice from Carl Trueman at Reformation 21 on Christians dealing with arguments involving "culture", especially in a post modern environment.
...am I alone in being sick to death of all the trendy talk about `culture'? A biblical approach to reality seems to involve, first and foremost, a commitment to the notion of essences. Culture is very real but, as a social construct it is not the ultimate reality; nor is it, therefore, the ultimate reality. This seems to me the problem with much postmodernism: it's obsession with culture at the expense of essence has created moral chaos. For example, how can one have inalienable human rights when there is no inalienable human nature? Hence the silliness on the left these days where ... moral equivalence arguments are made between feudal genocide, as in Saddam's Iraq, and poverty in post-feudal democracies. Any Marxist knows that capitalist democracy, for all its faults, is superior to feudalism in every way. Christians should take a leaf from the books of the palaeo-Marxists and return to talking about nature and essence, not culture.
...It also reminds the church, I think, that cultural change is not her primary task. But that's another story.
