President of the Lutheran World Federation Bishop Munib Younan (R) and Pope Francis attend an ecumenical event at the Malmo Arena 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
