18. Then indeed they blazed forth with such fury, and were so excited by the goadings of hatred, that scarcely any churches of our communion could be safe against their treachery and violence and most undisguised robberies; scarcely any road secure by which men could travel to preach the peace of the Catholic Church in opposition to their madness, and convict the rashness of their folly by the clear enunciation of the truth. They went so far, besides, in proposing hard terms of reconciliation, not only to the laity or to any of the clergy, but even in a measure to certain of the Catholic bishops. For the only alternative offered was to hold their tongues about the truth, or to endure their savage fury. But if they did not speak about the truth, not only was it impossible for any one to be delivered by their silence, but many were even sure to be destroyed by their submitting to be led astray; while if, by their preaching the truth, the rage of the Donatists was again provoked to vent its madness, though some would be delivered, and those who were already on our side would be strengthened, yet the weak would again be deterred by fear from following the truth. When the Church, therefore, was reduced to these straits in its affliction, any one who thinks that anything was to be endured, rather than that the assistance of God, to be rendered through the agency of Christian emperors, should be sought, does not sufficiently observe that no good account could possibly be rendered for neglect of this precaution.
Chap. v.—19. But as to the argument of those men who are unwilling that their impious deeds should be checked by the enactment of righteous laws, when they say that the apostles never sought such measures from the kings of the earth, they do not consider the different character of that age, and that everything comes in its own season. For what emperor had as yet believed in Christ, so as to serve Him in the cause of piety by enacting laws against impiety, when as yet the declaration of the prophet was only in the course of its fulfilment, "Why do the heathen rage, and the people imagine a vain thing? The kings of the earth set themselves, and their rulers take counsel together, against the Lord, and against His Anointed;" and there was as yet no sign of that which is spoken a little later in the same psalm: "Be wise now, therefore, O ye kings; be instructed, ye judges of the earth. Serve the Lord with fear, and rejoice with trembling."[1203] How then are kings to serve the Lord with fear, except by preventing and chastising with religious severity all those acts which are done in opposition to the commandments of the Lord? For a man serves God in one way in that he is man, in another way in that he is also king. In that he is man, he serves Him by living faithfully, but in that he is also king, he serves Him by enforcing with suitable rigour such laws as ordain what is righteous, and punish what is the reverse. Even as Hezekiah served Him, by destroying the groves and the temples of the idols, and the high places which had been built in violation of the commandments of God;[1204] or even as Josiah served Him, by doing the same things in his turn;[1205] or as the king of the Ninevites served Him, by compelling all the men of his city to make satisfaction to the Lord;[1206] or as Darius served Him, by giving the idol into the power of Daniel to be broken, and by casting his enemies into the den of lions;[1207] or as Nebuchadnezzar served Him, of whom I have spoken before, by issuing a terrible law to prevent any of his subjects from blaspheming God.[1208] In this way, therefore, kings can serve the Lord, even in so far as they are kings, when they do in His service what they could not do were they not kings.
20. Seeing, then, that the kings of the earth were not yet serving the Lord in the time of the apostles, but were still imagining vain things against the Lord and against His Anointed, that all might be fulfilled which was spoken by the prophets, it must be granted that at that time acts of impiety could not possibly be prevented by the laws, but were rather performed under their sanction. For the order of events was then so rolling on, that even the Jews were killing those who preached Christ, thinking that they did God service in so doing, just as Christ had foretold,[1209] and the heathen were raging against the Christians, and the patience of the martyrs was overcoming them all. But so soon as the fulfilment began of what is written in a later psalm, "All kings shall fall down before Him; all nations shall serve Him,"[1210] what sober-minded man could say to the kings, "Let not any thought trouble you within your kingdom as to who restrains or attacks the Church of your Lord; deem it not a matter in which you should be concerned, which of your subjects may choose to be religious or sacrilegious," seeing that you cannot say to them, "Deem it no concern of yours which of your subjects may choose to be chaste, or which unchaste?" For why, when free-will is given by God to man, should adulteries be punished by the laws, and sacrilege allowed? Is it a lighter matter that a soul should not keep faith with God, than that a woman should be faithless to her husband? Or if those faults which are committed not in contempt but in ignorance of religious truth are to be visited with lighter punishment, are they therefore to be neglected altogether?
Chap. vi.—21. It is indeed better (as no one ever could deny) that men should be led to worship God by teaching, than that they should be driven to it by fear of punishment or pain; but it does not follow that because the former course produces the better men, therefore those who do not yield to it should be neglected. For many have found advantage (as we have proved, and are daily proving by actual experiment), in being first compelled by fear or pain, so that they might afterwards be influenced by teaching, or might follow out in act what they had already learned in word. Some, indeed, set before us the sentiments of a certain secular author, who said,
"'Tis well, I ween, by shame the young to train,
And dread of meanness, rather than by pain."[1211]
This is unquestionably true. But whilst those are better who are guided aright by love, those are certainly more numerous who are corrected by fear. For, to answer these persons out of their own author, we find him saying in another place,
