Young people in particular, I appeal to you: bear witness to your faith through the digital world.

Help each other to live and to grow in the Christian faith so as to be valiant witnesses of the Lord. Be united, but not closed. Be humble, but not fearful. Be simple, but not naive. Be thoughtful, but not complicated. Enter into dialogue with others, but be yourselves.

Preservation of the environment, promotion of sustainable development and particular attention to climate change are matters of grave concern for the entire human family. No nation or business sector can ignore the ethical implications present in all economic and social development. With increasing clarity scientific research demonstrates that the impact of human actions in any one place or region can have worldwide effects.

Humanity today is rightly concerned about the ecological balance of tomorrow. It is important for assessments in this regard to be carried out prudently, in dialogue with experts and people of wisdom, uninhibited by ideological pressure to draw hasty conclusions, and above all with the aim of reaching agreement on a model of sustainable development capable of ensuring the well-being of all while respecting environmental balances.

May we be enlightened by a ray of the light that comes from Bethlehem, the light of He who is 'The Greatest' and made himself small.

You have suffered grievously and I am truly sorry. I know that nothing can undo the wrong you have endured. Your trust has been betrayed and your dignity has been violated.

May all our contemporaries stand beside their brothers and sisters in humanity. Each one of you is called by Christ and must be a missionary of the Good News in word and in active charity.
