What's Behind 'Rolling Stone' Decision to Ax Ad?

Why did Rolling Stone magazine decide, at the last moment, to not run an advertisement for a new translation of the Bible? One can only guess and such guessing would probably be irresponsible.

But if the magazine has decided that they simply won't take advertising dollars from anyone with a religious message, I hope that this policy will be clearly enunciated and adhered to consistently. As the article linked above points out, at least one religiously-based ad appears in the most recent issue of the magazine.
