Pope Francis visited a once-troubled and crime-plagued neighborhood in Portugal's capital on Friday to draw attention to the charitable side of the Catholic Church and the need to protect the world's most vulnerable people with concrete gestures that “get your hands dirty.” The midway point in Francis’ five-day visit to Portugal began with the pontiff hearing confessions of some young people who were in Lisbon for World Youth Day, the big Catholic festival. Francis visited a community center in the city's Serafina neighborhood, which sits beneath a giant 18th century aqueduct that is a symbol of the bounty that gold from Portugal’s Brazilian colony once afforded the country.
