The dome of St. Peter's Basilica, center, is framed by a Christmas tree at the Vatican Monday, Dec. 24, 2012. Pope Benedict XVI has lit a Christmas peace candle set on the windowsill of his private studio overlooking square. Pilgrims, tourists and Romans gathered below in St. Peter's Square for the inauguration Monday evening of a Nativity scene and cheered when the flame was lit. Later, he will appear in St. Peter's Basilica to lead Christmas Eve Mass. (AP Photo/Gregorio Borgia)
