Pope Francis kicked off the 2025 Holy Year on Tuesday, inaugurating a celebration of the Catholic Church that is expected to draw some 32 million pilgrims to Rome in a test of the pope's stamina and the ability of the Eternal City to welcome them.

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.
