A mural in one of Buenos Aires’ shantytowns, where “slum priests” have worked for decades, combating poverty, drug addiction and homelessness. The priests now have the support from the highest ranks of the Catholic Church. Jorge Mario Bergoglio, who served as archbishop of Buenos Aires for 15 years before taking the title of Pope Francis earlier this year, made the slum priests a priority. He tripled their numbers, opened new chapels and visited frequently, usually arriving on his own by city bus. (Kate Linthicum / Los Angeles Times)
