Pope Francis is traveling to once-strong bastions of Christianity in the heart of Europe to try to reinvigorate a Catholic flock that is dwindling in the face of secular trends and abuse scandals that have largely emptied the continent’s magnificent cathedrals and village churches. Francis is likely to dwell on Europe’s role past, present and future — particularly as war rages on European soil — during his visits to Luxembourg and Belgium, where he arrives later Thursday and stays through the weekend.
