Pope Francis meets King Carl XVI Gustaf of Sweden and Queen Silvia in the Kungshuset Royal Palace of Lund, Sweden, Monday, Oct. 31, 2016. Francis traveled to secular Sweden on Monday to mark the 500th anniversary of the Protestant Reformation, a remarkably bold gesture given his very own Jesuit religious order was founded to defend the faith against Martin Luther's "heretical" reforms five centuries ago.
