Assyria, however, was not only Force: she was also the symbol of a great Idea--the Idea of Unity. We have just ventured on one historical analogy. We may try another and a more exact one. The Empire of Rome, grasping the whole world in its power and reducing all races of men to much the same level of political rights, powerfully assisted Christian theology in the task of imposing upon the human mind a clearer imagination of unity in the government of the world and of spiritual equality among men of all nations. A not dissimilar service to the faith of Israel was performed by the Empire of Assyria. History, that hitherto had been but a series of angry pools, became as the ocean swaying in tides to one almighty impulse. It was far easier to imagine a sovereign Providence when Assyria reduced history to a unity by overthrowing all the rulers and all their gods, than when history was broken up into the independent fortunes of many states, each with its own religion divinely valid in its own territory. By shattering the tribes Assyria shattered the tribal theory of religion, which we have seen to be the characteristic Semitic theory--a god for every tribe, a tribe for every god. The field was cleared of the many: there was room for the One. That He appeared, not as the God of the conquering race, but as the Deity of one of their many victims, was due to Jehovah's righteousness. At this juncture, when the world was suggested to have one throne and that throne was empty, there was a great chance, if we may so put it, for a god with a character. And the only God in all the Semitic world who had a character was Jehovah.
It is true that the Assyrian Empire was not constructive, like the Roman, and, therefore, could not assist the prophets to the idea of a Catholic Church. But there can be no doubt that it did assist them to a feeling of the moral unity of mankind. A great historian has made the just remark that, whatsoever widens the imagination, enabling it to realise the actual experience of other men, is a powerful agent of ethical advance.[107] Now Assyria widened the imagination and the sympathy of Israel in precisely this way. Consider the universal Pity of the Assyrian conquest: how state after state went down before it, how all things mortal yielded and were swept away. The mutual hatreds and ferocities of men could not persist before a common Fate, so sublime, so tragic. And thus we understand how in Israel the old envies and rancours of that border warfare with her foes which had filled the last four centuries of her history is replaced by a new tenderness and compassion towards the national efforts, the achievements and all the busy life of the Gentile peoples. Isaiah is especially distinguished by this in his treatment of Egypt and of Tyre; and even where he and others do not, as in these cases, appreciate the sadness of the destruction of so much brave beauty and serviceable wealth, their tone in speaking of the fall of the Assyrian on their neighbours is one of compassion and not of exultation.[108] As the rivalries and hatreds of individual lives are stilled in the presence of a common death, so even that factious, ferocious world of the Semites ceased to _fret its anger and watch it for ever_ (to quote Amos' phrase) in face of the universal Assyrian Fate. But in that Fate there was more than Pity. On the data of the prophets Assyria was afflicting Israel for moral reasons: it could not be for other reasons that she was afflicting their neighbours. Israel and the heathen were suffering for the same righteousness' sake. What could have better illustrated the moral equality of all mankind! No doubt the prophets were already theoretically convinced[109] of this--for the righteousness they believed in was nothing if not universal. But it is one thing to hold a belief on principle and another to have practical experience of it in history. To a theory of the moral equality of mankind Assyria enabled the prophets to add sympathy and conscience. We shall see all this illustrated in the opening prophecies of Amos against the foreign nations.
