From the article:
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.
While we remain a nation decisively shaped by religious faith, our politics and our culture are, in the main, less influenced by movements and arguments of an explicitly Christian character than they were even five years ago. I think this is a good thing—good for our political culture, which, as the American Founders saw, is complex and charged enough without attempting to compel or coerce religious belief or observance. It is good for Christianity, too, in that many Christians are rediscovering the virtues of a separation of church and state that protects what Roger Williams, who founded Rhode Island as a haven for religious dissenters, called "the garden of the church" from "the wilderness of the world." As crucial as religion has been and is to the life of the nation, America's unifying force has never been a specific faith, but a commitment to freedom—not least freedom of conscience. At our best, we single religion out for neither particular help nor particular harm; we have historically treated faith-based arguments as one element among many in the republican sphere of debate and decision. The decline and fall of the modern religious right's notion of a Christian America creates a calmer political environment and, for many believers, may help open the way for a more theologically serious religious life.
That was a pretty wordy way of saying, "Worship any god(s) you like. It is your right under the Constitution to do so or not as you choose. Keep it to yourself. Respect my rights as well and quit trying to elect people and pass laws that will force me to believe as you say you do or there's gonna be trouble."
Many conservative Christians believe they have lost the battles over issues such as abortion, school prayer and even same-sex marriage, and that the country has now entered a post-Christian phase. [...]
I walked in the door about ten minutes ago with my new dead-tree copy of Newsweek and posted this on the strength of the cover. Now I am going to go sit on the couch and read the rest of it.
