Some of the effects of the earthquake are next spoken of. More especially, _The great city was divided into three parts, and the cities of the nations fell_. As to the meaning of "the cities of the nations" there can be no doubt. They are the strongholds of the world's sin, the places from which ungodliness and impiety have ruled. Under the shaking of the earthquake they fall in ruins. The first words as to "the great city" must be considered in connexion with the words which follow regarding Babylon, and they are more difficult to interpret. By some it is contended that the "great city" is Jerusalem, by others that it is Babylon. The expression is one which the Apocalypse must itself explain, and in seeking the explanation we must proceed upon the principle that in this book, as much as in any other of the New Testament, the rules of all good writing are followed, and that the meaning of the same words is not arbitrarily changed. When this rule, accordingly, is observed, we find that the epithet is, in chap. xi. 8, distinctly applied to Jerusalem, the words "the great city, where also their Lord was crucified" leaving no doubt upon the point. But, in chap. xviii. 10, 16, 18, 19, 21, the same epithet is not less distinctly applied to Babylon. The only legitimate conclusion is, that there is a sense in which Jerusalem and Babylon are one. This corresponds exactly to what we otherwise learn of the light in which the metropolis of Israel appeared to St. John. To him as an Apostle of the Lord, and during the time that he followed Jesus in the flesh, Jerusalem presented itself in a twofold aspect. It was the city of God's solemnities, the centre of the old Divine theocracy, the "holy city," the "beloved city."[441] But it was also the city of "the Jews," the city which scorned and rejected and crucified its rightful King. When in later life he beheld, in the picture once exhibited around him and graven upon his memory, the type of the future history and fortunes of the Church, the two Jerusalems again rose before his view, the one the emblem of all that was most precious, the other of all that was most repulsive, in the eyes both of God and of spiritually enlightened men. The first of these Jerusalems is the true Church of Christ, the faithful remnant, the little flock that knew the Good Shepherd's voice and followed Him. The second is the degenerate Church, the mass of those who misinterpreted the aim and spirit of their calling, and who by their worldliness and sin "crucified their Lord afresh, and put Him to an open shame." In the latter aspect Jerusalem _becomes_ Babylon. As in chap. xi. 8 it became "spiritually," that is mystically, "Sodom and Egypt," so it becomes also the mystical Babylon, partaker of that city's sins, and doomed to its fate. This thought we shall find fully expanded in the following chapter. The question may indeed be asked, how it comes to pass that, if this representation be correct, we
