If you know your religion-beat history, then you know this name — David Briggs, who is best known for his years with the Associated Press.

If you know your GetReligion history, then you know that — for 17 years — we have been saying that the “religious left” deserves more attention. This is specially true in terms of the doctrinal beliefs of people in these blue pews and how those beliefs help shape their politics.

It seems that, every four years or so — a telling interval — we see a few stories about a surge of activity on the religious left and how that will impact politicians opposed by the Religious Right. It’s like politics is the only reality, or something.

Thus, several readers noted this recent Briggs byline for the Association of Religion Data Archives: “The decline of the religious left in the age of Trump.”

Say what? Here’s the overture:

President Trump has had a powerful mobilizing effect on the liberal and secular left in U.S. politics.
But will religious liberals also play a significant role in getting out the vote for Democrat Joe Biden in November?
Almost immediately after the 2016 election, some commentators began heralding the likelihood that a revived religious left would emerge from what many liberals considered the ashes of Trump’s victory.
But such hopes may be based more on a wing and a prayer than solid evidence of any such new awakening. Rather, there are several signs indicating “a notable decline” in political activity among religious liberals.

'Mainline' blues: A veteran on religion beat gives an old church trend fresh legs

How many stories have been written on the important demographic slide across the decades among America’s moderate-to-liberal Protestant churches, the "Seven Sisters" of the old mainline?

Such pieces typically report the latest membership totals and such. But newswriters should always seek new ways to freshen up old themes, and colleague David Briggs provides an example of just how to do that.

In case anyone doesn’t know the name, Briggs was the Religion Guy’s predecessor as an Associated Press religion writer, also covered the beat for the Buffalo News and Cleveland Plain Dealer, and has been president of the Religion Newswriters Association. He now edits the “Ahead of the Trend” blog for the Association of Religion Data Archives, an organization housed at Penn State that religion journalists are -- or should be -- well aware of.

By the way, the ARDA boasts that Briggs is considered “among the Top 10 secular religion writers and reporters in North America,” which sounds right. Who’d be on your own list? Leave me some notes in the comments pages.

Here’s the old-school Briggs formula: Pull together telling data that haven’t gotten much coverage, interview some of the usual suspects on the implications and then propose a strong conclusion about mainline woe: “Not only is there no end in sight, but there are few signs of hope for revival in rapidly aging, shrinking groups.”

These churches won’t disappear, we’re told, but their decline will not bottom out, much less turn around.
