Arnobii adversus nationes Libri VII

Since I have found some who deem themselves very wise in their opinions, acting as if they were inspired, and announcing with all the authority of an oracle, that from the time when the Christian people began to exist in the world the universe has gone to ruin, that the human race has been visited with ills of many kinds, that even the very gods, abandoning their accustomed charge, in virtue of which they were wont in former days to regard with interest our affairs, have been driven from the regions of earth,—I have resolved, so far as my capacity and my humble power of language will allow, to oppose public prejudice, and to refute calumnious accusations; lest, on the one hand, those persons should imagine that they are declaring some weighty matter, when they are merely retailing vulgar rumours; and on the other, lest, if we refrain from such a contest, they should suppose that they have gained a cause, lost by its own inherent demerits, not abandoned by the silence of its advocates. For I should not deny that that charge is a most serious one, and that we fully deserve the hatred attaching to public enemies, if it should appear that to us are attributable causes by reason of which the universe has deviated from its laws, the gods have been driven far away, and such swarms of miseries have been inflicted on the generations of men.
