Now, thirdly and lastly, in order to try the question in an extreme form, let it be supposed that, aided by powers of working miracles, some early apostle of Christianity should actually have succeeded in carrying through the Copernican system of astronomy, as an article of blind belief, sixteen centuries before the progress of man's intellect had qualified him for naturally developing that system. What, in such a case, would be the true estimate and valuation of the achievement? Simply this, that he had thus succeeded in cancelling and counteracting a determinate scheme of divine discipline and training for man. Wherefore did God give to man the powers for contending with scientific difficulties? Wherefore did he lay a secret train of continual occasions, that should rise, by relays, through scores of generations, for provoking and developing those activities in man's intellect, if, after all, he is to send a messenger of his own, more than human, to intercept and strangle all these great purposes? This is to mistake the very meaning and purposes of a revelation. A revelation is not made for the purpose of showing to indolent men that which, by faculties already given to them, they may show to themselves; no: but for the purpose of showing _that_ which the moral darkness of man will not, without supernatural light, allow him to perceive. With disdain, therefore, must every thoughtful person regard the notion, that God could wilfully interfere with his own plans, by accrediting ambassadors to reveal astronomy, or any other science, which he has commanded men, by qualifying men, to reveal for themselves. Even as regards astronomy--a science so nearly allying itself to religion by the loftiness and by the purity of its contemplations--Scripture is nowhere the _parent_ of any doctrine, nor so much as the silent sanctioner of any doctrine. It is made impossible for Scripture to teach falsely, by the simple fact that Scripture, on such subjects, will not condescend to teach at all. The Bible adopts the erroneous language of men (which at any rate it must do, in order to make itself understood), not by way of sanctioning a theory, but by way of using a fact. The Bible, for instance, _uses_ (postulates) the phenomena of day and night, of summer and winter; and, in relation to their causes, speaks by the same popular and inaccurate language which is current for ordinary purposes, even amongst the most scientific of astronomers. For the man of science, equally with the populace, talks of the sun as rising and setting, as having finished half his day's journey, &c., and, without pedantry, could not in many cases talk otherwise. But the results, which are all that concern Scripture, are equally true, whether accounted for by one hypothesis which is philosophically just, or by another which is popular and erring.
