There are some publications that treat religion-news coverage like a trip to some mysterious planet where the inhabitants are incomprehensible. Such was the San Francisco Weekly’s recent take on a local exorcist. It was so crammed with mistakes, one wonders if anyone bothered editing or fact checking the piece.

The Weekly has had some decent religion stories in the past, but this was not one of them.

Which is a shame, because the issue of exorcism is wildly interesting, the stuff of movies and best-selling books. The reporter identifies himself as a lapsed Catholic non-believer, which makes it odd that the research would be so sloppy.

We begin:

Every Thursday evening, a few dozen people file into Immaculate Conception Chapel, a small Catholic church on the steep slope of Folsom Street on Bernal Hill's north face, carrying bottles of water, tubs of protein powder, small bottles of booze, watches, rosaries, and cell phones...

The people stir a few minutes past 7 p.m. when a tiny man wearing white robes -- a long rectangle of cloth with Vegas-worthy golden sparkles hanging around his neck -- appears from a door to the left of the altar. A few weeks shy of his 89th birthday, Father Guglielmo Lauriola walks slowly across the raised altar area to a waiting chair. Here he sits, facing away from his congregation in the style of the pre-Vatican II Latin Mass, to read from laminated card prayers and songs devoted to the Virgin Mary. Aside from Jesus on the cross, she is the principal figure of veneration here at the 104-year-old church.

So the scene is set. This priest conducts a Mass, after which, we're told "the show really starts."
