I put together these three facts of human history, the vision of the King of Babylon interpreted by Daniel six hundred years before Christ, the summary of its fulfilment down to his own age written by St Augustine four hundred years after the coming of Christ, and his delineation, a few years later, of the Two Cities, as set forth by him in a work on which the Christian mind has now been nurtured for fourteen hundred and fifty years. The simple juxtaposition of these shows how Babylon stretches to Rome, and Rome is heir of Babylon; and the heathen man thus formed illustrates "the Man who is born in Sion, the city of the great King."[6] It is true that the two great Powers of Civil and Spiritual government, the relation between which forms the subject of this volume, are not exactly represented as concerns that relation in the vision of Daniel; but only the heathen growth of the Civil Power, and the miraculous rise, permanent rule, and progressive growth of the Spiritual Power in the midst of it; yet the mighty promise is recorded that in presence of the Civil Power the Spiritual shall never pass away; rather that it shall last unchanged, while the other is shifting and transitory; and also the cognate truth, that the great and terrible Power represented by the Statue is, in the counsels of God, subordinate in its scope to the Power represented by the Stone. It is true, again, that the vivid contrast of the Two Cities as drawn by St. Augustine does not represent the legitimate relation of the Two Powers to each other, but only the perversion of the one Power from its true end and object, and the perfect antagonism of the other to that perversion. But the kingdom set up by the God of heaven in the vision interpreted by Daniel, and the connection of ages dwelt upon by St. Augustine, which leads up to the Person of Christ, and then starts afresh from Him, and the Divine City delineated by St. Augustine, fit exactly into each other, and so they seem to me to form together an appropriate introduction to that most remarkable period of history with which the present volume is occupied, when the Stone cut out without hands struck the Statue, and became a great mountain, in preparation for that further growth when it would fill the whole earth.
