President of the Lutheran World Federation Bishop Munib Younan (L), Pope Francis (C), and General Secretary of the Lutheran World Federation Rev Martin Junge arrive at the Malmo Arena for an ecumenical event on October 31, 2016 in Malmo, Sweden. Pope 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
