Pope Francis is presented with a gift of a crucifix carved into a wooden hammer and sickle, the Communist symbol uniting labor and peasants, by Bolivian President Evo Morales in La Paz, Bolivia. Apart from the carved hammer and sickle, Morales gave Francis another politically loaded gift, a copy of "The Book of the Sea," which is about the loss of Bolivia's access to the sea during the War of the Pacific with Chile in 1879-83. Morales said things have changed with this pope and the Bolivian people are greeting Francis as someone who is "helping in the liberation of our people."

Pope Francis waves to reporters at Rome's Fiumicino International airport as he boards his flight to Quito, Ecuador, where he will start a week-long trip to South America, including Bolivia and Paraguay. Francis is taking his "church for the poor" to three of South America's poorest and most peripheral countries, making a grueling, week-long trip that will showcase the pope at his unpredictable best: speaking his native Spanish on his home turf about issues closest to his heart.
