From Whispers in the Loggia, the Christmas homily of Pope Francis:
In our personal history too, there are both bright and dark moments, lights and shadows. If we love God and our brothers and sisters, we walk in the light; but if our heart is closed, if we are dominated by pride, deceit, self-seeking, then darkness falls within us and around us. “Whoever hates his brother – writes the Apostle John – is in the darkness; he walks in the darkness, and does not know the way to go, because the darkness has blinded his eyes” (1 Jn 2:11).
On this night, like a burst of brilliant light, there rings out the proclamation of the Apostle: “God’s grace has been revealed, and it has made salvation possible for the whole human race” (Tit 2:11).
The grace which was revealed in our world is Jesus, born of the Virgin Mary, true man and true God. He has entered our history; he has shared our journey. He came to free us from darkness and to grant us light. In him was revealed the grace, the mercy, and the tender love of the Father: Jesus is Love incarnate. He is not simply a teacher of wisdom, he is not an ideal for which we strive while knowing that we are hopelessly distant from it. He is the meaning of life and history, who has pitched his tent in our midst.
