He made the remarks a day after the start of the Roman Catholic Church’s Holy Year, known as a Jubilee, which takes place every quarter century. On Tuesday evening, Francis opened the Holy Door in St. Peter’s Basilica so that the first pilgrims could go through. Millions more are expected to follow over the year.

Pope Francis prayed that the Jubilee Year may become “a season of hope” and reconciliation in a world at war and suffering humanitarian crises as he opened the Holy Door in St. Peter’s Basilica on Christmas Eve.

The pope also voiced concern about the humanitarian crisis in Gaza in his Christmas address, labeling the situation "extremely grave."
