Madonna Kabbalah - what is the difference between catholicism and kabbbalah?

"Guy Ritchie always says, 'The difference between Kabbalah and Catholicism is the amount of people,' " says Berg, sitting in an office at the center's New York branch. A Madonna biography stands in the bookshelf behind him. "You don't call Catholicism a cult."

And if Madonna's outreach efforts find continued success, Berg says, the critics will be quieted.

"Eventually, when there's enough people doing Kabbalah" — when there are as many people wearing Red Strings as crosses — "it won't even be an issue."
