Madonna's precarious relationship with the Vatican is under scrutiny again following their concern over her support of the controversial Kabbalah faith. While the "Papa Don't Preach" star, 45, is a staunch supporter of the mystical offshoot of Judaism - Catholic leaders are holding a summit to discuss any fad religions they feel may pose a 'threat' to Christianity including the Kabbalah, according to American gossip site The Scoop. Cult expert Rick Ross says, "In the past, the Pope has criticized Madonna for the contents of her concerts. Now, ironically, it's become a theological issue." The Vatican is holding a special summit with Catholic leaders from around the world with the aim to negotiate a deal with so-called 'New Age' religions and fads that pose a 'threat' to Christianity.
