Commonitory for the Antiquity and Universality of the Catholic Faith

The evil resulting from the bringing in of Novel Doctrine shown in the instances of the Donatists and Arians.

[9.] But that we may make what we say more intelligible, we must illustrate it by individual examples, and enlarge upon it somewhat more fully, lest by aiming at too great brevity important matters be hurried over and lost sight of.

In the time of Donatus, from whom his followers were called Donatists, when great numbers in Africa were rushing headlong into their own mad error, and unmindful of their name, their religion, their profession, were preferring the sacrilegious temerity of one man before the Church of Christ, then they alone throughout Africa were safe within the sacred precincts of the Catholic faith, who, detesting the profane schism, continued in communion with the universal Church, leaving to posterity an illustrious example, how, and how well in future the soundness of the whole body should be preferred before the madness of one, or at most of a few.

[10.] So also when the Arian poison had infected not an insignificant portion of the Church but almost the whole world, so that a sort of blindness had fallen upon almost all the bishops of the Latin tongue, circumvented partly by force partly by fraud, and was preventing them from seeing what was most expedient to be done in the midst of so much confusion, then whoever was a true lover and worshipper of Christ, preferring the ancient belief to the novel misbelief, escaped the pestilent infection.

[11.] By the peril of which time was abundantly shown how great a calamity the introduction of a novel doctrine causes. For then truly not only interests of small account, but others of the very gravest importance, were subverted. For not only affinities, relationships, friendships, families, but moreover, cities, peoples, provinces, nations, at last the whole Roman Empire, were shaken to their foundation and ruined. For when this same profane Arian novelty, like a Bellona or a Fury, had first taken captive the Emperor, and had then subjected all the principal persons of the palace to new laws, from that time it never ceased to involve everything in confusion, disturbing all things, public and private, sacred and profane, paying no regard to what was good and true, but, as though holding a position of authority, smiting whomsoever it pleased. Then wives were violated, widows ravished, virgins profaned, monasteries demolished, clergymen ejected, the inferior clergy scourged, priests driven into exile, jails, prisons, mines, filled with saints, of whom the greater part, forbidden to enter into cities, thrust forth from their homes to wander in deserts and caves, among rocks and the haunts of wild beasts, exposed to nakedness, hunger, thirst, were worn out and consumed. Of all of which was there any other cause than that, while human superstitions are being brought in to supplant heavenly doctrine, while well established antiquity is being subverted by wicked novelty, while the institutions of former ages are being set at naught, while the decrees of our fathers are being rescinded, while the determinations of our ancestors are being torn in pieces, the lust of profane and novel curiosity refuses to restrict itself within the most chaste limits of hallowed and uncorrupt antiquity?
