Pope Francis is shaking up the Catholic Church and putting the Vatican back on the world stage.
The Argentine-born pontiff's stances on issues like the LGBT community, women, and the environment are changing the public perception of the Church. Some see him as a Marxist pope, someone who has defiantly aligned himself with the poor. Others view him as a rock star pontiff who defies norms and appeals to a new generation of Catholics.
But just how deep is he transforming the Church? Are his gestures more symbolic than real?
As Pope Francis embarks on a visit to the United States, we look at his rise to the papacy in Fusion's documentary Saint or Sinner: Pope Francis. Watch all six parts of the special below.
