Our own age has afforded a very remarkable instance of this kind. To this it is sufficient to allude, without entering into any further disquisition concerning it. But it is not only in such wonderful changes for good or happy deliverances from the power of evil that these remarkable divine moments or theocratic junctures announce themselves in the history of the world. We may even recognize them in every commencement of a truly new era in history, which, in the favorable crisis, is suddenly and triumphantly effected by a some higher impulse and divinely-imparted power. Many instances of the kind might easily be adduced if this were the proper place for it, or time allowed. The first triumph of the Cross and Christianity that was public and extended to the whole world, under Constantine the Great, belongs to this class. As a second instance, I would mention that beginning of the Christian Empire in the West under Charlemagne, which was afterward to receive so happy a development. Superficial inquirers, who judge by the mental external coloring, are in danger of confounding these creative beginnings--these turning-points of a higher intervention--with the ordinary event of a revolution, or the rapid and decisive step of energetic usurpation. But to the eye of patient observation and deep penetration they are distinguished from the latter by their profound historical causes and their attendant circumstances, and by a peculiar stamp of purity and grandeur. In short, in their essence they are entirely different. These observations must have made it evident in what sense I spoke of a theocracy of science. The power of truth in that good science which is directed toward God, is in its influence of a lofty and even divine nature. But it is this simply, in its immediate energy of operation, without depending on any external sanction, or even form thereof. In the same way error also, in its evil effects, is most unquestionably, and in the fullest sense of the term, a power; and that not merely in a sensuous and materialistic, or relatively to the mind in a purely negative sense, but a demoniacal power of evil with a most embarrassing and perverting influence, such as it has been often and in our own times most undeniably exercised. The great degree in which science actually manifests itself as a power is not apparent so long as we limit our consideration to the history of the human intellect in our own circle of observation and the ordinary sphere of European civilization.
