The birth of Jesus at Bethlehem is not an event that can be consigned to the past. The whole of human history in fact stands in reference to him; our own time and the future of the world are illuminated by his presence. He is “the Living One” (Rev 1:18), “who is, who was and who is to come” (Rev 1:4). Before him every knee must bend, in the heavens, on earth and under the earth, and every tongue proclaim that he is Lord (Phil 2: 10-11). In the encounter with Christ, every man discovers the majesty of his own life.
Jesus is the genuine newness which surpasses all human expectations and such he remains forever, from age to age. The Incarnation of the Son of God and the salvation which he has accomplished by his death and resurrection are therefore the true criterion for evaluating all that happens in time and every effort to make life more human.
