A young nun plays on a seesaw as she awaits the arrival of Pope Francis outside the Sao Joaquim Palace in Rio de Janeiro, July 26, 2013. Pope Francis on Thursday issued the first social manifesto of his young pontificate, telling slum dwellers in Brazil that the world's rich must do much more to wipe out vast inequalities between the haves and the have-nots.
