The mystery of Christmas lays upon us all a debt and an obligation to the rest of [humankind] and to the whole created universe. We who have seen the light of Christ are obliged, by the greatness of the grace that has been given us, to make known the presence of the Savior to the ends of the earth. This we will do not by preaching the glad tidings of His coming, but above all by revealing Him in our lives. Christ is born to us today, in order that He may appear to the whole world through us ■ Thomas Merton, Seasons of Celebration, New York: Farrar, Straus & Giroux, 1965, 112.
