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.

Prior to offering his blessing "urbi et orbi," Francis prayed for peace in Ukraine, the Holy Land, Lebanon and Syria, and in Africa.

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