A long, long time ago — the 10th anniversary of my national “On Religion column” — I wrote a tribute to the trailblazing work of sociologist James Davison Hunter of the University of Virginia. How long ago was that? Well, today is the 31st anniversary of my first syndicated column hitting the wires.

Hunter is best known as the author of “Culture Wars: The Struggle to Define America.” This book, more than any other, has influenced my work as a religion-beat columnist.

The words “culture wars” are used all the time by people who clearly have never read Hunter’s book. His thesis is that the old doctrinal, horizontal, denomination divisions in American life have been replaced by a vertical fault line that is much more basic, cutting into almost all religious pews and pulpits.

Hang in there with me. I am working my way to the rapid emergence of South Bend (Ind.) Mayor Pete Buttigieg as a White House candidate, in part because of his ability to unite Democrats on the religious and non-religious left. I wrote about that the other day (“Who says journalists hate religion? USA Today welcomes liberal Christian faith of Pete Buttigieg“) and “Crossroads” host Todd Wilken and I returned to that topic in this week’s podcast. (Click here to tune that in or head over to iTunes and sign up.)

But back to Hunter and the religious schism in modern America’s foundation:

The old dividing lines centered on issues such as the person of Jesus Christ, church tradition and the Protestant Reformation. But these new interfaith coalitions were fighting about something even more basic — the nature of truth and moral authority.

Two years later, Hunter began writing "Culture Wars: The Struggle to Define America," in which he declared that America now contains two basic world views, which he called "orthodox" and "progressive." The orthodox believe it's possible to follow transcendent, revealed truths. Progressives disagree and put their trust in personal experience, even if that requires them to "resymbolize historic faiths according to the prevailing assumptions of contemporary life."

So, what was the big quote from Buttigieg that sent a Barack-Obama-style thrill up the legs of legions of journalists and inspired waves of news coverage?
