"It's not violent revolutions that change the world, but the quiet light of truth, a sign of God's presence, which gives us the certainty that we are loved and we are not the product of chance but a desire for love." Those were the Pope'�s words this morning as he celebrated Mass on the Third Sunday of Advent in the Roman parish of St. Maximilian Kolbe.

It is a suburban parish and the new church is dedicated to this Polish Franciscan saint, who was martyred in the concentration camp of Auschwitz. A saint is a light, like Father Mariano de Veuster and Mother Teresa of Calcutta, said the Pope, a path of light brought by Christ into world, not with power but with the strength of humility and love. Over the last two or three centuries, the Pope explained, their came many, ideologies and dictators, who through their totalitarian regimes changed the world in a destructive manner, and in the end there was emptiness and destruction. In a parish with many families who come from Central and South America, and also Eastern Europe and also from China, Pope Benedict urged the faithful to grow more and more in communion with everyone, because he said, "it is important to create opportunities for dialogue and foster mutual understanding between people from different cultures, ways of life and different social conditions.
