VATICAN CITY — When Pope Francis orders the Holy Door at St. Peter's Basilica open Dec. 8 for the start of the Extraordinary Jubilee of Mercy, tens of thousands of Catholic pilgrims — and the tightest security the Vatican has ever seen — will be on hand for the occasion.In the wake of the Nov. 13 attacks in Paris, the Vatican stepped up security dramatically. A heavier police presence is noticeable around St. Peter's Square, and security checks for those entering St. Peter's Basilica have become more thorough.
