Pope Francis celebrated the traditional Christmas Mass at the Vatican's St. Peter's Basilica church, and in his sermon spoke of how God loves everyone, even the worst of mankind.

During the Mass on Christmas Eve, when Catholics commemorate the birth of the Lord Jesus, Francis on Tuesday said of his coming: "We realise that, when we failed to measure up, God became small for our sake; while we were going about our own business, he came into our midst."
