Pope Francis urged inmates to never give up hope as he inaugurated the Vatican’s Jubilee Year at the high-security Rebibbia prison on the outskirts of Rome on Thursday.

Pope Francis inaugurated his Holy Year at Rome’s main prison on Thursday, bringing a message of hope to inmates and involving them in the Catholic Church’s once-every-quarter century celebration that is expected to bring some 32 million pilgrims to Rome.

Pope Francis made a visit on Thursday to one of the largest prison complexes in Italy, opening a special "Holy Door" for the 2025 Catholic Holy Year, in what the Vatican said was the first such action by a Catholic pontiff.

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 has called for a “negotiation” to end the war in Ukraine in a Christmas Day message where he appealed for weapons to be laid down in global conflicts and reconciliation between enemies.
