The 88-year-old Pope Francis opened the Holy Door of St. Peter’s Basilica before Mass on Christmas Eve, officially launching the Jubilee Year 2025.

He made the remarks a day after the start of 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.
