Benedict XVI Formally Installed as Pope
Hundreds of thousands of pilgrims pack into St. Peter's Square to watch Cardinal Joseph Ratzinger's formal installation as Pope Benedict XVI in a huge, open-air mass. The new pontiff offered a warm greeting to all non-Catholics and urged humanity to rediscover God to help transform the ills of the world.
