Thus, after the event, we can plainly see that the final blow to Polytheism was the suppression of the ancient independent nationalities around the Mediterranean Sea; and that, in like manner, Monotheism was the result of the establishment of an imperial government in Rome. But the great statesmen of those times, who were at the general point of view, must have foreseen that, in whatever form the expected change came, its limits of definition would inevitably be those of the empire itself, and that wherever the language of Rome was understood the religion of Rome would prevail. In the course of ages, an expansion beyond those limits might ensue wherever the state of things was congenial. On the south, beyond the mere verge of Africa, nothing was to be hoped for--it is the country in which man lives in degradation and is happy. On the east there were great unsubdued and untouched monarchies, having their own types of civilization, and experiencing no want in a religious respect. But on the north there were nations who, though they were plunged in hideous barbarism, filthy in an equal degree in body and mind, polygamists, idolaters, drunkards out of their enemies' skulls, were yet capable of an illustrious career. For these there was a glorious participation in store. [Sidenote: The new ideas coalesce with the old.] Except the death of a nation, there is no event in human history more profoundly solemn than the passing away of an ancient religion, though religious ideas are transitory, and creeds succeed one another with a periodicity determined by the law of continuous variation of human thought. The intellectual epoch at which we have now arrived has for its essential characteristic such a change--the abandonment of a time-honoured but obsolete system, the acceptance of a new and living one; and, in the incipient stages, opinion succeeding opinion in a well-marked way, until at length, after a few centuries of fusion and solution, there crystallized on the remnant of Roman power, as on a nucleus, a definite form, which, slowly modifying itself into the Papacy, served the purposes of Europe for more than a thousand years throughout its age of Faith.
