City of God

But possibly, though Varro is a heathen historian, and a very learned one, they may disbelieve that what I have cited from him truly occurred; or they may say the example is invalid, because the star did not for any length of time continue to follow its new course, but returned to its ordinary orbit. There is, then, another phenomenon at present open to their observation, and which, in my opinion, ought to be sufficient to convince them that, though they have observed and ascertained some natural law, they ought not on that account to prescribe to God, as if He could not change and turn it into something very different from what they have observed.

The land of Sodom was not always as it now is; but once it had the appearance of other lands, and enjoyed equal if not richer fertility; for, in the divine narrative, it was compared to the paradise of God. But after it was touched [by fire] from heaven, as even pagan history testifies, and as is now witnessed by those who visit the spot, it became unnaturally and horribly sooty in appearance; and its apples, under a deceitful appearance of ripeness, contain ashes within. Here is a thing which was of one kind, and is of another.

You see how its nature was converted by the wonderful transmutation wrought by the Creator of all natures into so very disgusting a diversity—an alteration which after so long a time took place, and after so long a time still continues. As therefore it was not impossible to God to create such natures as He pleased, so it is not impossible to Him to change these natures of His own creation into whatever He pleases, and thus spread abroad a multitude of those marvels which are called monsters, portents, prodigies, phenomena, and which if I were minded to cite and record, what end would there be to this work?

They say that they are called “monsters,” because they demonstrate or signify something; “portents,” because they portend something; and so forth. But let their diviners see how they are either deceived, or even when they do predict true things, it is because they are inspired by spirits, who are intent upon entangling the minds of men (worthy, indeed, of such a fate) in the meshes of a hurtful curiosity, or how they light now and then upon some truth, because they make so many predictions.

Yet, for our part, these things which happen contrary to nature, and are said to be contrary to nature (as the apostle, speaking after the manner of men, says, that to graft the wild olive into the good olive, and to partake of its fatness, is contrary to nature), and are called monsters, phenomena, portents, prodigies, ought to demonstrate, portend, predict that God will bring to pass what He has foretold regarding the bodies of men, no difficulty preventing Him, no law of nature prescribing to Him His limit. How He has foretold what He is to do, I think I have sufficiently shown in the preceding book, culling from the sacred Scriptures, both of the New and Old Testaments, not, indeed, all the passages that relate to this, but as many as I judged to suffice for this work.
