Pope Francis (C) is greeted by Swedish Prime Minister Stefan Loefven (2ndR) and clerics 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 / JONATHAN NACKSTRAND
