It is not true that religion reached its acme nineteen hundred years ago, and that we are for ever to refer back to what was written and said in those days. No, sir religion is a vital living thing, still growing and working, capable of endless extension and development, like all other fields of thought. There were many eternal truths spoken of old and handed down to us in a book, some parts of which may indeed be called holy. But there are others yet to be revealed and if we are to reject them because they are not in those pages, we should act as wisely as the scientist who would take no notice of Kirschoff's spectral analysis because there is no mention of it in Albertus Magnus.
