A lot is being made of the new Pew numbers out, showing continued declines for churches and the now one in five Americans who don't affiliate with religion. One thing I see a lot coming from traditionally oriented Christians is the taking of the opportunity to yet again mock the fish in the barrel that are "spiritual but not religious" persons.
Every day when I go to work I get in the car, pass the JW Kingdom Hall on the corner of my street, then pass an Islamic center, then pass two decidedly health and wealth (you can tell from the messages on the signs out front) black pentecostal churches, and that is within a mile or so from my house. I probably pass 30 or so churches on the way to work (12 miles - Memphis does have the highest number of churches per capita of any city in the country). Sometimes I take an alternative route which runs me by 15 different churches than the usual route. So let's call the total number of churches 45. From what I know of these churches via things heard about them or their signage or their folks coming to my house and leaving literature and/or talking to me, I would rather my kids grow up to be "spiritual but not religious" than attend any these churches, with the possible exception of one of them.
In my adult life, I have visited many hundreds of parishes - Mainline Prot, Evangelical, Catholic, Orthodox, Quaker, Unitarian, etc. I suppose I'd rather my kids grow up to be "spiritual but not religious" than attend approximately half of the parishes I have visited in my adult life, and that includes some particularly disordered Catholic and Orthodox ones.
Of all the bosses I've had in my life, the worst have been the practicing Christians, with the possible exception of one who was a mix of incredibly benevolent and patient and incredibly condescending and dysfunctional. The best boss I've ever had is my current one - a philandering agnostic who brags about the number of abortions he paid for when he was in the local rich kid Evangelical high school. The "spiritual but not religious" bosses I've had have generally been level headed and competent and fair. My wife's best boss ever is a liberal Catholic - one of those most trad and conservative Catholics I know would rather not be in the RCC and one who sounds, when she talks about faith matters, like she is "spiritual and not religious" -- she likes to "thank the universe" for things and send out "positive energy" and so forth. Every Prot Christian my wife has ever worked for has been a royal pain in the ass. So was the one Orthodox boss she briefly had (though that doesn't really count because he was a convert and his "boss style" was decidedly conservative Evangelical - he was also a monkabee who espoused the most overt antinomianism I've ever heard from an Orthodox in person, but when it came to running his business, whew - then he was all scruples and rigidity and micromanagement and dotting every i and crossing every t and yelling at you if you put too much mustard on the sandwich, and let me tell you, if my wife thinks you pay too much attention to detail and are anal about it when doing a job, you are one seriously fucked up freak). My wife told me once that she plans on only working for liberal Catholics from here on out. They drink a lot, they throw good parties, and they are generous.
We've shared this with my mother, and with a number of friends of ours, and sure enough, a sizable chunk of my friends seem to agree with my mother that "Christians make the worst bosses" (usually they mean by that Evangelicals, fundies, and other conservative Prots).
In every school setting I have ever found myself in, the "spiritual but not religious" folks were the sort that were more likely than the overtly hostile-to-spiritual-things or overtly religious to be reliable without being annoying. Those that made a point of letting you know that they were practicing Christians were, 7 times out of 10, not the sort of people most of us would want to spend much time with, whereas most of the folks I have known outside of more alternative-ish (wannabe hippy - hippies younger than the age of 50 tend to be irritating as all get out) circles who self-identify as "spiritual but not religious" have been fairly easy to work with and get along with and benign enough in their spouting interpretations of life and the world, etc.
None of this is a proof of anything, of course, or an argument, or meant to sway anyone's opinion about anything. It's just anecdotal ephemera from my life. And it probably has something to do with why, when I hear the Pew numbers, I think, "well, of course."
