Granting, however, that all we have found in the Decalogue's conception of Yahweh was present to the mind of Moses, and granting that the commands which deal with the relations of men to each other are not mere isolated prohibitions, but are founded upon moral principles which were understood even then to have much wider implications, there still remains a gap between the widest meaning that early time could put into them, and that which Luther's Catechism, or the Catechism of the Westminster Divines, for example, asserts. The question therefore arises whether these wider and more detailed explanations, which make the Decalogue cover the whole field of the moral and religious life, are legitimate, and if so, on what principle can they be justified? The reply would seem to be that they are legitimate, and that the ten words did contain much more than Moses or any of his nation for many centuries after him understood. For any fruitful thought, any thought which really penetrates the heart of things, must have in it wider implications than the first thinker of it can have conceived. If by any means a man has had insight to see the central fact of any domain of thought and life, its applications will not be limited to the comparatively few cases to which he may apply it. He will generally be content to deduce from his discovery just those conclusions which in his circumstances and in his day are practically useful and are most clamorously demanded. But those who come after, pressed by new needs, challenged by new experiences, and enlightened by new thoughts in related regions, will assuredly find that more was involved in that first step than any one had seen. The scope of the fruitful principle will thus inevitably widen with the course of things, and inferences undreamed of by those who first enunciated the principle will be securely drawn from it by later generations. Now if that be true in regard to truths discovered by the unassisted intellect of man, how much more true will it be of thoughts which have first been revealed to man under the influence of inspiration? Behind the human mind which received them and applied them to the circumstances which then had to be dealt with, there is always the infinite mind which sees that "Far-off Divine event To which the whole creation moves."
