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.

Pope Francis said the story of Jesus' birth as a poor carpenter's son should instil hope that all people can make an impact on the world, as the pontiff on Tuesday led the world's Roman Catholics into Christmas.
