"That really hit me hard," he told me last week. "The Northwest was never as religious, never as congregationalized, as the Northeast, which was the foundation, the home base, of American religion. To lose New England struck me as momentous." Turning the report over in his mind, Mohler posted a despairing online column on the eve of Holy Week lamenting the decline—and, by implication, the imminent fall—of an America shaped and suffused by Christianity. "A remarkable culture-shift has taken place around us," Mohler wrote. "The most basic contours of American culture have been radically altered. The so-called Judeo-Christian consensus of the last millennium has given way to a post-modern, post-Christian, post-Western cultural crisis which threatens the very heart of our culture." When Mohler and I spoke in the days after he wrote this, he had grown even gloomier. "Clearly, there is a new narrative, a post-Christian narrative, that is animating large portions of this society," he said from his office on campus in Louisville, Ky.
There it was, an old term with new urgency: post-Christian. This is not to say that the Christian God is dead, but that he is less of a force in American politics and culture than at any other time in recent memory. To the surprise of liberals who fear the advent of an evangelical theocracy and to the dismay of religious conservatives who long to see their faith more fully expressed in public life, Christians are now making up a declining percentage of the American population.
