Walk in the light this Christmas
Pope Francis has invited people to open their hearts to the light of Jesus in his first Christmas Eve mass.
He spoke of the fight against the "spirit of darkness" as he urged people to walk in the light.
"If we love God and our brothers and sisters, we walk in the light; but if our heart is closed, if we are dominated by pride, deceit, self-seeking, then darkness falls within us and around us," he said.
The Pope pointed to the image of the shepherds who were told about the birth of Jesus, saying they were "among the last, the outcast".
During the mass at St Peter's Basilica in the Vatican, Pope Francis held a statue of the baby Jesus.
