“’There is no graded scale of essential worth,’ [Martin Luther King Jr.] King had written a year before his assassination. ‘Every human being has etched in his personality the indelible stamp of the creator. Every man must be respected because God loves him.’ Every woman too, a feminist might have added. Yet King’s words, while certainly bearing witness to an instinctive strain of patriarchy within Christianity, bore witness as well to why, across the Western world, this was coming to seem a problem. That every human being possessed an equal dignity was not remotely self-evident truth. A Roman would have laughed at it. To campaign against discrimination on the grounds of gender or sexuality, however, was to depend on large numbers of people sharing in a common assumption: that everyone possessed an inherent worth. The origins of this principle – as Nietzsche had so contemptuously pointed out – lay not in the French Revolution, nor in the Declaration of Independence, nor in the Enlightenment, but in the Bible.”
