From the moment he stepped onto the Vatican balcony high above St. Peter's Square, it was clear there was something different about him.He wore a plain white robe, a simple cross and offered a casual "Good evening.""Buona sera," he said, and the crowd roared its approval.In the year since Jorge Mario Bergoglio became Pope Francis, that roar has hardly diminished."Rock star Pope takes the world by storm," says longtime Vatican journalist John Allen. "That's become the dominant narrative."As Allen, who writes for the Boston Globe and works regularly in Rome, points out, the story of the Catholic Church a year ago was scandal - pedophile priests, Vatican bank corruption and gay conspiracies in the Vatican.Those stories haven't gone away, Allen say, but Pope Francis now dominates headlines about the Catholic Church.The crowds attending audiences in St. Peter's Square have, by some reports, tripled since Francis took office.Person of the YearHe attracted an estimated three million people to a mass at Copacabana Beach in Rio de Janiero last summer, outdrawing even the Rolling Stones.Time magazine chose him as Person of the Year, as did The Advocate, a LGBT publication.And yes, just like a rock star, he was the February cover story in Rolling Stone magazine.But can a rock star Pope really revolutionize the Catholic Church?Certainly Pope Francis is in many ways redefining what it is to be a modern pope.He refuses to live in the luxury of the papal apartments. He is often known to just pick up the phone and call people, offering sympathy and prayers.He kisses babies with the ease of a well-practiced politician and seems to truly enjoy the occasions when he's caught in a crush of happy worshippers. He is the new, friendly face of the Catholic Church - the Pope as pastor.Pope Francis
