But it is the occasion of this great Apology which invests it at once with grandeur and vitality. After more than eleven hundred years of steady and triumphant progress, Rome had been taken and sacked. It is difficult for us to appreciate, impossible to overestimate, the shock which was thus communicated from centre to circumference of the whole known world. It was generally believed, not only by the heathen, but also by many of the most liberal-minded of the Christians, that the destruction of Rome would be the prelude to the destruction of the world.[8] Even Jerome, who might have been supposed to be embittered against the proud mistress of the world by her inhospitality to himself, cannot conceal his profound emotion on hearing of her fall. "A terrible rumour," he says, "reaches me from the West, telling of Rome besieged, bought for gold, besieged again, life and property perishing together. My voice falters, sobs stifle the words I dictate; for she is a captive, that city which enthralled the world."[9] Augustine is never so theatrical as Jerome in the expression of his feeling, but he is equally explicit in lamenting the fall of Rome as a great calamity; and while he does not scruple to ascribe her recent disgrace to the profligate manners, the effeminacy, and the pride of her citizens, he is not without hope that, by a return to the simple, hardy, and honourable mode of life which characterized the early Romans, she may still be restored to much of her former prosperity.[10] But as Augustine contemplates the ruins of Rome's greatness, and feels, in common with all the world at this crisis, the instability of the strongest governments, the insufficiency of the most authoritative statesmanship, there hovers over these ruins the splendid vision of the city of God "coming down out of heaven, adorned as a bride for her husband." The old social system is crumbling away on all sides, but in its place he seems to see a pure Christendom arising. He sees that human history and human destiny are not wholly identified with the history of any earthly power--not though it be as cosmopolitan as the empire of Rome.[11] He directs the attention of men to the fact that there is another kingdom on earth,--a city which hath foundations, whose builder and maker is God. He teaches men to take profounder views of history, and shows them how from the first the city of God, or community of God's people, has lived alongside of the kingdoms of this world and their glory, and has been silently increasing, "crescit occulto velut arbor ævo." He demonstrates that the superior morality, the true doctrine, the heavenly origin of this city, ensure its success; and over against this, he depicts the silly or contradictory theorizings of the pagan philosophers, and the unhinged morals of the people, and puts it to all candid men to say, whether in the presence of so manifestly sufficient a cause for Rome's downfall, there is
