Pilgrims pray in front of a large screen in Saint Peter’s Square, as they watch a televised mass led by newly elected Pope Francis in the Sistine Chapel, at the Vatican March 14, 2013. In his first public Mass, Pope Francis urged the Catholic Church on Thursday to stick to its roots and shun modern temptations, warning that it would become just “a compassionate NGO” if it forgot its true mission.
