Pope Francis (R) greets wellwishers as he makes his way from the King's House to the Lund Cathedral on October 31, 2016 in Lund, Sweden. Francis kicked 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
