Among Christians, the word “peace” has taken on a very particular meaning: it has become a word to designate communion in the Eucharist. There Christ’s peace is present. In all the places where the Eucharist is celebrated, a great network of peace spreads through the world. The communities gathered around the Eucharist make up a kingdom of peace as wide as the world itself. When we celebrate the Eucharist we find ourselves in Bethlehem, in the “house of bread”. Christ gives himself to us and, in doing so, gives us his peace. He gives it to us so that we can carry the light of peace within and give it to others. He gives it to us so that we can become peacemakers and builders of peace in the world. And so we pray: Lord, fulfill your promise! Where there is conflict, give birth to peace! Where there is hatred, make love spring up! Where darkness prevails, let light shine! Make us heralds of your peace! Amen.

Pope Benedict XVI
