Pope Francis (C) flanked by Arch bishop Munib A Younan (L) and Martin Junge of the Lutheran world federation after an ecumenical prayer at the Lund Cathedral on October 31, 2016 in Lund, 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 / TT News Agency / Jonas EKSTROMER / Sweden OUT
