A new and graver problem here arises. This revelation, made in the depths of the human soul, remains individual and subjective. How will it become objective and concrete? How will it be made an educating, saving power? This problem would be insoluble if Leibniz was right, if human souls were independent monads, closed against and impenetrable to one another, if it had been necessary, in a word, to regard them as absolute entities, posited from the beginning by the Creator. But they are nothing of the kind. Social philosophy has sufficiently demonstrated that no individual exists either by himself or for himself alone. In each man it is humanity that is realised--that is to say, a moral life common to all. Moral goods are in essence universal. They do not exist, doubtless, apart from the consciousness of the individual; but no consciousness acquires them without acquiring them, in principle at least, for all others. Whence comes that religious kinship of souls, that facility of communion between them, and that infinite extension and prolongation of one and the same inspiration, if not from the presence in each of the same indwelling God? Men are only divided by their external idols. In proportion as they plumb their being and descend into the depths of their spiritual nature, they discover the same altar, recite the same prayer, aspire to the same end. It is for this profound reason that individual revelations become universal. There are only prophets chosen of God because there is a general vocation and election of all men. If humanity were not potentially and in some degree an Immanuel (God with us), there would never have issued from its bosom Him who bore and revealed this blessed name. The religious experience He passed through, He passed through for us; the victory He won was for our advantage and is repeated indefinitely in every sincere soul that joins itself to Him to live His life. Thus the revelation of God given at one point and in one consciousness infallibly shines forth, perpetuates and multiplies itself. A vibration set up in a soul resounds in kindred souls. An illumined consciousness illuminates in turn. There are religious filiations, just as there are historical genealogies. Thus the inner revelation becomes consistent and objective in history; it forms a chain, a continuous tradition, and becoming incarnate in each human generation, remains not only the richest of heritages, but the most fecund of historical powers.
