But we have one step further to take. For as the spiritual faculty is the recipient directly or indirectly of that original revelation which God has made of Himself to His rational creatures, so too this appears to be the only faculty which can take cognizance of any fresh revelation that it might please Him to make. If He commands still further duties than those commanded by the supreme Moral Law, if He bids us believe what our reason cannot deduce from the primal belief in that Law and in Himself, it is to that faculty that the command is issued. If over and above the original religion as we may call it there is a revealed religion, it is the spiritual faculty that can alone accept it. Such a revelation may be confirmed by signs or proofs in the world of phenomena. He who is absolute over all nature may compel nature to bear witness to His teaching. The spiritual may burst through the natural on occasion, and that supremacy, which underlies all nature and which is necessarily visible to intelligences that are capable of seeing things as they are in themselves, may force itself into the world of phenomena and show itself in that manner to us. But this always is and must be secondary. The spiritual faculty alone can receive and judge of spiritual truth, and if that faculty be not reached a truly religious belief is not yet attained. External evidences of revealed religion must have a high place but cannot have the highest. A revealed religion must depend for its permanent hold on our obedience and our duty on its fastening upon our spiritual nature, and if it cannot do that no evidences can maintain it in its place.
