16. Chap. V.

You now see therefore, I suppose, that the thing to be considered when any one is coerced, is not the mere fact of the coercion, but the nature of that to which he is coerced, whether it be good or bad: not that any one can be good in spite of his own will, but that, through fear of suffering what he does not desire, he either renounces his hostile prejudices, or is compelled to examine truth of which he had been contentedly ignorant; and under the influence of this fear repudiates the error which he was wont to defend, or seeks the truth of which he formerly knew nothing, and now willingly holds what he formerly rejected. Perhaps it would be utterly useless to assert this in words, if it were not demonstrated by so many examples. We see not a few men here and there, but many cities, once Donatist, now Catholic, vehemently detesting the diabolical schism, and ardently loving the unity of the Church; and these became Catholic under the influence of that fear which is to you so offensive by the laws of emperors, from Constantine, before whom your party of their own accord impeached Caecilianus, down to the emperors of our own time, who most justly decree that the decision of the judge whom your own party chose, and whom they preferred to a tribunal of bishops, should be maintained in force against you.
