Pope Francis wraps up the first leg of a three-nation South American pilgrimage Wednesday after issuing an impassioned call for a new economic and ecological world order where the goods of the Earth are shared by everyone, not just exploited by the rich.

Francis will visit the elderly and give a pep talk to local priests before flying to Bolivia, where the environment, ministering to the poor and the government’s tense relations with the Catholic Church are high on the agenda. MORE
