These Prophets of Righteousness ... believed in the victory of absolute Righteousness, yet the fact that they turn their gaze time after time to "the end of days "proves that they knew—as by a whisper from the "spirit of holiness" within them—how great and how arduous was the work that mankind must do before that consummation could be reached. They knew, also, that such work as this could not be done by scattered individuals, approaching it sporadically, each man for himself, at different times and in different places; but that it needed a whole community, which should be continuously, throughout all generations, the standard-bearer of the force of Righteousness against all the other forces that rule the world: which should assume of its own freewill the yoke of eternal obedience to the absolute dominion of a single Idea, and for the sake of that Idea should wage incessant war against the way of the world.
