Thomas Merton - on his feast day - writing on Advent
It is important to remember the deep, in some ways anguished seriousness of Advent, when the mendacious celebrations of our marketing culture so easily harmonize with our tendency to regard Christmas, consciously or otherwise, as a return to our own innocence and our own infancy. Advent should remind us that the "King Who is to Come" is more than a charming infant smiling (or if you prefer a dolorous spirituality, weeping) in the straw. There is certainly nothing wrong with the traditional family joys of Christmas, nor need we be ashamed to find ourselves still able to anticipate them without too much ambivalence. After all, that in itself is no mean feat.
But the Church in preparing us for the birth of a "great prophet," a Savior and a King of Peace, has more in mind than seasonal cheer. The Advent mystery focuses the light of faith upon the very meaning of life, of history, of man, of the world and of our own being. In Advent we celebrate the coming and indeed the presence of Christ in our world. We witness to His presence even in the midst of all its inscrutable problems and tragedies. Our Advent faith is not an escape from the world to a misty realm of slogans and comforts which declare our problems to be unreal, our tragedies inexistent. . . . Our task is to seek and find Christ in our world as it is, and not as it might be. The fact that the world is other than it might be does not alter the truth that Christ is present in it and that His plan has been neither frustrated nor changed: indeed, all will be done according to His will. Our Advent is the celebration of this hope.
