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.

"I invite every individual, and all people of all nations ... to become pilgrims of hope, to silence the sounds of arms and overcome divisions," the pope said from the loggia of St. Peter's Basilica to throngs of people below.
