A pilgrim holds up a candle in front of a large screen showing Pope Benedict XVI as he conducts a Vespers service with young people at the fairground in Freiburg September 24, 2011. Pope Benedict straddled his homeland's religious and geographic divisions on Saturday, praising the faithful for enduring communism's "acid rain" effect in former East Germany and then addressing cheering Catholic crowds in the west. The Bavarian-born pontiff is on a four-day visit to Germany, his third visit to his homeland since he took over as head of the Catholic church.
