Pope Benedict XVI urged immigrants on Sunday to respect the social values of their new countries and said laws are needed to protect their dignity.Benedict, addressing pilgrims and tourists in St. Peter's Square, said migration should be seen as a resource, not a problem. Without naming any country or nationality, he lamented the "painful" conditions refugees, exiles, the homeless and the persecuted often endure. "I hope that soon there will be a balanced management of migratory flows and of human mobility in general, so benefits can reach the entire human family, beginning with concrete measures which favor legal emigration and the reuniting of families," the pontiff added.
