There is a famous passage in Sulpicius Severus (fourth century) which most modern scholars consider to have been an extract from a lost book of Tacitus. It is an account of a Council of War held after the storming of Jerusalem, A.D. 70. In this Council, Titus the son and heir of Vespasian—the hero of the great campaign which closed with the fall of Jerusalem—is reported to have expressed the opinion that the Temple ought to be destroyed in order that the religion of the Jews and of the Christians might be more completely rooted up; for these religions, though opposed to each other, had yet the same origin. The Christians had sprung from the Jews, and when the root was torn up the stem issuing from the root would easily be destroyed. There is no doubt but that this report of Titus’ speech at the Council of War is an historical document of the utmost importance. It tells us exactly what was the feeling of the imperial Flavian House towards the Christians—they represented an evil which it was well to extirpate.

It is possible that in a mutilated passage of Suetonius a reference occurs to Vespasian’s actions at this period (in the year following A.D. 70) in respect to the Christians. The passage runs as follows: “Never in the death of any one did Vespasian (take pleasure, and in the case of) merited punishments he even wept and groaned.” This is clearly a reference to some class of individuals whose punishment Vespasian felt bound to accept, while he regretted it. “It is inconceivable that Vespasian, a Roman soldier of long experience in the bloody wars of Britain and Judæa, wept and groaned at every merited execution.... We think of the punishments which by the principle of Nero attached to the Christians ... the principle in question continued permanently, and Suetonius alluded to it on account of the detail, interesting to a biographer, that Vespasian wept while he confirmed its operation.”[13]

But a yet more precise statement, that persecution was actively continued under Vespasian, is to be found in the Latin Father, Hilary of Poitiers, who ranks Vespasian between Nero and Decius as a persecutor of the Faith.[14] Some critics have supposed this notice an error. Lightfoot, however, thinks it more probable that it was based upon some facts of history known to Hilary, but since blotted out by time from the records of history.[15]

Towards the end of Domitian’s reign, circa A.D. 95, the persecution became more bitter. Indeed, so severely were the Christians hunted out and prosecuted that the period had become memorable in history. Domitian is constantly mentioned as the second great persecutor, Nero being the first. The reason doubtless for this general tradition is that in A.D. 95, persons of the highest rank, some even belonging to the imperial family, were among the condemned; notably Flavius Clemens the Consul, and the two princesses bearing the name of Domitilla—all these being very near relatives of the Emperor.

The violent outbreak of persecution, fierce and terrible as it seems to have been in the last year and a half of Domitian’s reign, does not appear to have been owing to any special movement among the Christian subjects of the Empire which aroused attention and suggested distrust, but was solely owing to the Emperor’s private policy and personal feelings. There is nothing to show that any edict against the sect was promulgated in this reign. Since the time of Nero the persecution of Christians was a standing matter, as was that of persons who were habitual law-breakers, robbers, and such-like. Probably under the princes of the Flavian dynasty, as we have said, this policy of the government was somewhat developed throughout the Empire, and now and again, owing to local circumstances and the disposition of the chief magistrate, was more or less severe. It is said that some governors boasted that they had brought back from their province their lictors’ axes unstained with blood; but others were actuated with very different feelings.

In the case of the so-called Domitian persecution, the ill-will of the autocratic Emperor naturally intensified it. Various motives seem to have influenced the sovereign Lord of the Empire here.

Domitian was a sombre and suspicious tyrant, and no doubt his cruel action in the case of his relatives, the consul Flavius and the princesses of his House, was prompted by jealousy of those who stood nearest his throne, and the fact that they were found to belong to the proscribed sect gave him a pretext of which he was glad to avail himself. But his bloody vengeance was by no means only wreaked upon his own relatives. We learn from the pagan writer Dion Cassius (in the epitome of his work by the monk Xiphilin) and also from Suetonius, that he put to death various persons of high position, notably Acilius Glabrio who had been consul in A.D. 91. This Acilius Glabrio was also a Christian. The researches and discoveries of De Rossi and Marruchi in the older portion of the vast Catacomb of S. Priscilla have conclusively proved this.

There was another reason, however, for Domitian’s special hatred of the Christian sect. The Emperor was a vigilant censor, and an austere guardian of the ancient Roman traditions. In this respect he has with some justice been cited as pursuing the same policy as did his great predecessor Augustus, and, like him, he looked on the imperial cultus[16] as part of the State religion. Domitian felt that these ancient traditions which formed a part of Roman life were compromised by the teaching and practices of the Christian sect. No doubt this was one of the principal reasons which influenced him in his active persecution of the followers of Jesus.

But although he struck at some of the noblest and most highly placed in the Empire, especially, as it seems, those suspected of being members of the hated sect, he appears to have vented his fury also upon many who belonged to the lower classes of the citizens. Juvenal in a striking passage evidently alludes to his pursuit of these comparatively unknown and obscure ones, and traces the unpopularity which eventually led to his assassination to this persecution of the poor nameless citizen.[17]
