Pope Benedict XVI is helped walk down steps by his aides as he presides a New Year's Eve vespers service in St. Peter's Basilica at the Vatican, Monday, Dec. 31, 2012. Pope Benedict XVI has marked the end of a difficult year by saying that despite all the death and injustice in the world, goodness prevails. Benedict celebrated New Year's Eve with a vespers service in St. Peter's Basilica to give thanks for 2012 and look ahead to 2013. He looked tired during the service and used a cane afterward, an indication that the busy Christmas season may be taking a toll on the 85-year-old Benedict. (AP Photo/Andrew Medichini)
