For the great and powerful of this world, there are only two places in which their courage fails them, of which they are afraid deep down in their souls, from which they shy away. These are the manger and the cross of Jesus Christ. No powerful person dares to approach the manger, and this even includes King Herod. For this is where thrones shake, the mighty fall, the prominent perish, because God is with the lowly. Here the rich come to nothing, because God is with the poor and hungry, but the rich and satisfied he sends away empty. Before Mary, the maid, before the manger of Christ, before God in lowliness, the powerful come to naught; they have no right, no hope; they are judged.
Who among us will celebrate Christmas correctly? Whoever finally lays down all power, all honor, all reputation, all vanity, all arrogance, all individualism beside the manger; whoever remains lowly and lets God alone be high; whoever looks at the child in the manger and sees the glory of God precisely in his lowliness.
