I conceive therefore that revelation is as universal as religion itself, that it descends as low, goes as far, ascends as high, and accompanies it always. No form of piety is empty; no religion is absolutely false; no prayer is vain. Once more, revelation is in prayer and progresses with prayer. From a revelation obtained in a first prayer is born a purer prayer, and from this a higher revelation. Thus light grows with life, truth with piety. This makes it possible for me to enter into communion and sympathy with all sincerely religious souls, however simple and however crude or gross their worship and their faith; but if I can comprehend them, I cannot always speak their language or share their ideas. All religions are not equally good, nor are all prayers acceptable to my consciousness. To return to exploded superstitions or to beliefs now recognised to be illusory is as much a moral impossibility as it would be for a full-grown man to return to the puerilities of his childhood. Revelation therefore is not a communication once for all of immutable doctrines which only need to be held fast. The object of the revelation of God can only be God Himself, and if a definition must be given of it, it may be said to consist of the creation, the purification, and the progressive clearness of the consciousness of God in man,--in the individual and in the race. From this point of view, I see very clearly that the revelation of God never needs to be proved to any one. The attempt would be as contradictory as it is superfluous. Two things are equally impossible: for an irreligious man to discover a divine revelation in a faith he does not share, or for a truly pious man not to find one in the religion he has espoused and which lives in his heart. With what, moreover, and how could it be proved that light shines except by forcing those who are asleep to awake and open their eyes? All serious Apologetics must insist as a necessary starting-point on the awakening and conversion of the soul. Having always been religious, mankind has never been destitute of revelation, that is to say of witness more or less obscure, more or less correctly interpreted, of the presence in it and the action of God. But if men have always maintained some relation and some commerce with the deity, they have not always represented in the same manner the mode in which communications have been received from Him. The notion of revelation has progressed with the growth of mental enlightenment and with the nature of the piety. It is therefore necessary to criticise that notion and to see what it has now become for us. It is to this examination that I shall devote this second meditation. The idea of revelation has passed through three phases in the course of history: the mythological, the dogmatic, and the critical. 2. _The Mythological Notion of Revelation_
