Pope Francis (C) is greeted by Swedish Prime Minister Stefan Loefven (R) upon his arrival at the airport on October 31, 2016 in Malmo, Sweden. Pope Francis kicks off a two-day visit to Sweden to mark the 500th anniversary of the Reformation -- a highly symbolic trip, given that Martin Luther's dissenting movement launched centuries of bitter and often bloody divisions in Europe. / AFP PHOTO / VINCENZO PINTO
