A previous Religion Guy Memo looked at Canada's spiritual landscape as it celebrates its 150th anniversary.

That item provoked an e-mail response worth pondering by journalistic analysts. The writer is Kenneth A. Briggs, a competitor and friendly colleague as religion editor of The New York Times during the Religion Guy’s early years writing for Time magazine’s religion section. Briggs, also an award-winner for his work at Long Island Newsday, later became a college teacher, book author and independent journalist in varied media projects.

Importantly for this context, Briggs is a certified mainline Protestant as a Yale Divinity School graduate and an ordained elder in the largest U.S. mainline denomination, the United Methodist Church (which granted him a “special appointment” for journalistic work).

First, Briggs asks whether the Religion Guy was “suggesting cause-and-effect” in stating that  both Canada and the U.S. “show remarkable losses for ‘mainline’ churches that have floated leftward”? These Protestants’ gradual numerical decline and liberal shifts this past half-century are established facts, but Briggs says the two could be simply “coincidental,” rather than that liberalism caused decline.

The Guy -- yes -- meant to imply that a shift toward more liberal doctrinal beliefs was one contributor to the unprecedented membership losses, with breakaways by local congregations, outright schisms, and individual members switching to other options or forsaking church altogether. Meanwhile, conservatives often held steady or gained adherents (though note the past decade’s smaller, but significant, decline for the staunchly conservative Southern Baptist Convention). 

Briggs calls that scenario -- linking doctrinal changes and numerical decline -- “evangelical boilerplate.”

The Guy must quickly add that factors other than liberalism played into church trends.
