Fasten your seatbelt, dear reader.

There’s cussing up ahead.

That’s right: R-rated language made it into the religion news. Again.

Before we cite the specifics, let’s consider this guidance from the Associated Press Stylebook — aka “the journalist’s bible” — on obscenities, profanities and vulgarities:

Do not use them in stories unless they are part of direct quotations and there is a compelling reason for them.

In this week’s examples, the words in question showed up in coverage of “Disloyal: A Memoir,” a new book by Michael Cohen, “President Trump’s longtime fixer,” as the Wall Street Journal described him.

The Journal reported:

Mr. Cohen describes the president as lacking either faith or piety and recounts him disparaging various groups, including his own supporters. In 2012, after meeting with religious leaders at Trump Tower, where they asked to “lay hands” on Mr. Trump, Mr. Cohen recalls his asking: “Can you believe that bull****?…Can you believe people believe that bull****?”

Note: The asterisks were not used in the actual Journal news story.

The White House dismissed the book’s claims as “lies” by “a disgraced felon and disbarred lawyer.”

But whether the quote is fact or fiction, the notion of Trump uttering a profanity is not difficult to believe.

After all, the future president was caught on videotape delivering the famous “Grab-em-by-the-p****” line. And Politico wrote last year about Trump irritating evangelicals by “using the Lord’s name in vain.”

Perhaps more surprising — then again, maybe not given recent allegations — was the quote Reuters attributed to Becki Falwell. She is the wife of Jerry Falwell Jr., the prominent evangelical leader who recently resigned as president of Liberty University.

The book ties Falwell Jr.’s 2016 endorsement of Trump to Cohen “helping to keep racy ‘personal’ photographs of the Falwells from becoming public.”

Campaign 2020 question: Do Christians see a difference between cussing and profanity?

THE QUESTION:

A four-letter topic raised by campaign 2020: What does Christianity teach about cussing?

THE RELIGION GUY’S ANSWER:

The vulgar lingo associated with military barracks, so tiresome and over-used in movies, cable TV shows and pop music, is filtering into U.S. politics.

Several candidates this campaign have gone potty-mouth, but it’s a specialty of “Beto” O’Rourke. He dropped the f-bomb in his Texas Senate concession speech last November and promised to “keep it clean” when a perturbed voter complained, only to backslide. His staff has made this a proud trademark, selling $30 T-shirts that display the expletive. Muslim Congresswoman Rashida Tlaib then imitated T-shirt sales to broadcast her own four-syllable obscenity. O’Rourke also remarked of Donald Trump, “Jesus Christ, of course he’s racist.”

Contra Tlaib, is there a sexist double standard at work? Indiana University’s Michael Adams, the author of “In Praise of Profanity,” thinks filth that may possibly give male candidates a populist appeal will count against female candidates.

O’Rourke emulates Mr. Trump himself, who boasted in 2016 that he never uses the f-word though videotapes tell a different story. Last February, the President reportedly hurled three f-bombs at the nation’s leading Democrat, Nancy Pelosi, during a White House meeting, and later apologized.

A la O’Rourke, the latest Trump hubbub involves the name of God. Most media coverage of a North Carolina rally focused on the President for not lamenting the crowd’s racially tinged “send her back” chants against Congresswoman Ilhan Omar, a Muslim immigrant. But some of the religious voters he relies upon were upset that he twice uttered “g–d—“ during that appearance. Soon after, he uttered the same phrase in a talk to all House Republicans.
