City of God, Book XXI
Nevertheless these cavillers at faith and exactors of reason, how do they dispose of those things of which a reason cannot be given, and which yet exist, though in apparent contrariety to the nature of things? If we had announced that these things were to be, these sceptics would have demanded from us the reason of them, as they do in the case of those things which we are announcing as destined to be. And consequently, as these present marvels are not non-existent, though human reason and discourse are lost in such works of God, so those things we speak of are not impossible because inexplicable; for in this particular they are in the same predicament as the marvels of earth.
Chapter 6.—That All Marvels are Not of Nature’s Production, But that Some are Due to Human Ingenuity and Others to Diabolic Contrivance.
At this point they will perhaps reply, “These things have no existence; we don’t believe one of them; they are travellers’ tales and fictitious romances;” and they may add what has the appearance of argument, and say, “If you believe such things as these, believe what is recorded in the same books, that there was or is a temple of Venus in which a candelabrum set in the open air holds a lamp, which burns so strongly that no storm or rain extinguishes it, and which is therefore called, like the stone mentioned above, the asbestos or inextinguishable lamp.” They may say this with the intention of putting us into a dilemma: for if we say this is incredible, then we shall impugn the truth of the other recorded marvels; if, on the other hand, we admit that this is credible, we shall avouch the pagan deities. But, as I have already said in the eighteenth book of this work, we do not hold it necessary to believe all that profane history contains, since, as Varro says, even historians themselves disagree on so many points, that one would think they intended and were at pains to do so; but we believe, if we are disposed, those things which are not contradicted by these books, which we do not hesitate to say we are bound to believe. But as to those permanent miracles of nature, whereby we wish to persuade the sceptical of the miracles of the world to come, those are quite sufficient for our purpose which we ourselves can observe or of which it is not difficult to find trustworthy witnesses. Moreover, that temple of Venus, with its inextinguishable lamp, so far from hemming us into a corner, opens an advantageous field to our argument. For to this inextinguishable lamp we add a host of marvels wrought by men, or by magic,—that is, by men under the influence of devils, or by the devils directly,—for such marvels we cannot deny without impugning the truth of the sacred Scriptures we believe. That lamp, therefore, was either by some mechanical and human device fitted with asbestos, or it was arranged by magical art in order that the worshippers might be astonished, or some devil under the name of Venus so signally manifested himself that this prodigy both began and became permanent. Now devils are attracted to dwell in certain temples by means of the creatures (God’s creatures, not theirs), who present to them what suits their various tastes. They are attracted not by food like animals, but, like spirits, by such symbols as suit their taste, various kinds of stones, woods, plants, animals, songs, rites. And that men may provide these attractions, the devils first of all cunningly seduce them, either by imbuing their hearts with a secret poison, or by revealing themselves under a friendly guise, and thus make a few of them their disciples, who become the instructors of the multitude. For unless they first instructed men, it were impossible to know what each of them desires, what they shrink from, by what name they should be invoked or constrained to be present.
Hence the origin of magic and magicians. But, above all, they possess the hearts of men, and are chiefly proud of this possession when they transform themselves into angels of light. Very many things that occur, therefore, are their doing; and these deeds of theirs we ought all the more carefully to shun as we acknowledge them to be very surprising. And yet these very deeds forward my present arguments. For if such marvels are wrought by unclean devils, how much mightier are the holy angels! and what can not that God do who made the angels themselves capable of working miracles!
If, then, very many effects can be contrived by human art, of so surprising a kind that the uninitiated think them divine, as when, e.g ., in a certain temple two magnets have been adjusted, one in the roof, another in the floor, so that an iron image is suspended in mid-air between them, one would suppose by the power of the divinity, were he ignorant of the magnets above and beneath; or, as in the case of that lamp of Venus which we already mentioned as being a skillful adaptation of asbestos; if, again, by the help of magicians, whom Scripture calls sorcerers and enchanters, the devils could gain such power that the noble poet Virgil should consider himself justified in describing a very powerful magician in these lines:
“Her charms can cure what souls she please,
Rob other hearts of healthful ease,
Turn rivers backward to their source,
And make the stars forget their course,
And call up ghosts from night:
The ground shall bellow ’neath your feet:
The mountain-ash shall quit its seat,
And travel down the height;” —
if this be so, how much more able is God to do those things which to sceptics are incredible, but to His power easy, since it is He who has given to stones and all other things their virtue, and to men their skill to use them in wonderful ways; He who has given to the angels a nature more mighty than that of all that lives on earth; He whose power surpasses all marvels, and whose wisdom in working, ordaining, and permitting is no less marvellous in its governance of all things than in its creation of all!
Chapter 7.—That the Ultimate Reason for Believing Miracles is the Omnipotence of the Creator.
Why, then, cannot God effect both that the bodies of the dead shall rise, and that the bodies of the damned shall be tormented in everlasting fire,—God, who made the world full of countless miracles in sky, earth, air, and waters, while itself is a miracle unquestionably greater and more admirable than all the marvels it is filled with? But those with whom or against whom we are arguing, who believe both that there is a God who made the world, and that there are gods created by Him who administer the world’s laws as His viceregents,—our adversaries, I say, who, so far from denying emphatically, assert that there are powers in the world which effect marvellous results (whether of their own accord, or because they are invoked by some rite or prayer, or in some magical way), when we lay before them the wonderful properties of other things which are neither rational animals nor rational spirits, but such material objects as those we have just cited, are in the habit of replying, This is their natural property, their nature; these are the powers naturally belonging to them. Thus the whole reason why Agrigentine salt dissolves in fire and crackles in water is that this is its nature. Yet this seems rather contrary to nature, which has given not to fire but to water the power of melting salt, and the power of scorching it not to water but to fire. But this they say, is the natural property of this salt, to show effects contrary to these. The same reason, therefore, is assigned to account for that Garamantian fountain, of which one and the same runlet is chill by day and boiling by night, so that in either extreme it cannot be touched. So also of that other fountain which, though it is cold to the touch, and though it, like other fountains, extinguishes a lighted torch, yet, unlike other fountains, and in a surprising manner, kindles an extinguished torch. So of the asbestos stone, which, though it has no heat of its own, yet when kindled by fire applied to it, cannot be extinguished. And so of the rest, which I am weary of reciting, and in which, though there seems to be an extraordinary property contrary to nature, yet no other reason is given for them than this, that this is their nature,—a brief reason truly, and, I own, a satisfactory reply.
But since God is the author of all natures, how is it that our adversaries, when they refuse to believe what we affirm, on the ground that it is impossible, are unwilling to accept from us a better explanation than their own, viz., that this is the will of Almighty God,—for certainly He is called Almighty only because He is mighty to do all He will,—He who was able to create so many marvels, not only unknown, but very well ascertained, as I have been showing, and which, were they not under our own observation, or reported by recent and credible witnesses, would certainly be pronounced impossible? For as for those marvels which have no other testimony than the writers in whose books we read them, and who wrote without being divinely instructed, and are therefore liable to human error, we cannot justly blame any one who declines to believe them.
