“In short we may say that faith in Man, by the combined effect of its universality and its elemental quality, shows itself upon examination to be the general atmosphere in which the higher, more elaborated forms of faith which we all hold in one way or another may best (indeed can only) grow and come together. It is not a formula, it is the environment of union.
No one can doubt that we are all more or less affected by this elementary, primordial faith. Should we otherwise truly belong to our time? And if, through the very force of our spiritual aspirations, we have been inclined to mistrust it, even to feel that we are immune from it, we must look more closely into our own hearts. I have said that the soul has only one summit. But it has also only one foundation. Let us look well and we shall find that our Faith in God, detached as it may be, sublimates in us a rising tide of human aspirations. It is to this original sap that we must return if we wish to communicate with the brothers and sister with whom we seek to be united.”
