46. The knowledge of the stars, again, is not a matter of narration, but of description. Very few of these, however, are mentioned in Scripture. And as the course of the moon, which is regularly employed in reference to celebrating the anniversary of our Lord's passion, is known to most people; so the rising and setting and other movements of the rest of the heavenly bodies are thoroughly known to very few. And this knowledge, although in itself it involves no superstition, renders very little, indeed almost no assistance, in the interpretation of Holy Scripture, and by engaging the attention unprofitably is a hindrance rather; and as it is closely related to the very pernicious error of the diviners of the fates, it is more convenient and becoming to neglect it. it involves, moreover, in addition to a description of the present state of things, something like a narrative of the past also; because one may go back from the present position and motion of the stars, and trace by rule their past movements. It involves also regular anticipations of the future, not in the way of forebodings and omens, but by way of sure calculation; not with the design of drawing any information from them as to our own acts and fates, in the absurd fashion of the genethliaci, but only as to the motions of the heavenly bodies themselves. For, as the man who computes the moon's age can tell, when he has found out her age today, what her age was any number of years ago, or what will be her age any number of years hence, in just the same way men who are skilled in such computations are accustomed to answer like questions about every one of the heavenly bodies. And I have stated what my views are about all this knowledge, so far as regards its utility.
