Madonna- Several years ago, we started to notice a red string tied around Madonna’s wrist and it raised a few eyebrows as we weren’t familiar with the religion it was associated with- Kabbalah.  But it seems that times have changed for the Kabbalah enthusiast and she is now interested in a religion called Opus Dei - the secretive Catholic sect made famous in The Da Vinci Code. The theology of Opus Dei teaches "universal holiness," which is the belief that everyone should aspire to be a saint. Although Madonna was reportedly interested in ditching Kabbalah for Opus Dei- she hasn’t been documented as a “paid member.” Whatever that means.
