Pope Francis celebrates a mass at the Swedenbank Stadion in Malmo, Sweden, on November 1, 2016. Francis is on 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 AND TT News Agency / Jonas EKSTROMER / Sweden OUT
