To transform the world, God chose a humble maiden from a village in Galilee, Mary of Nazareth, and greeted her thus: ‘Rejoice, full of grace, the Lord is with you.’ The secret of an authentic Christmas lies in these words. God repeats them to the Church, to each one of us: Rejoice, the Lord is near!

With the help of Mary, let us offer ourselves with humility and courage so the world may welcome Christ, who is the source of true joy.

Pope Benedict XVI

Christmas Day is a holy day of obligation.
