Reading the 4 millionth Ross Douthat column on why people should behave the way Ross Douthat thinks they should behave I just have to wonder...why does he - and people like him - spend so much time fretting about this stuff? I mean who cares who is married and who is cohabitating and who is having the sexytime etc. I know the short answer is Because Christianity, but without wading into One True Christian territory, all that stuff really isn't exactly the central focus of the New Testament.
