VATICAN CITY (AP) — Pope Benedict XVI marked the end of a difficult year Monday 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 appeared 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.
