By a law of the empire, which was not revoked until nearly three hundred years afterwards, under Constantine, the profession of the Christian religion was made a capital offence. This law, it is true, was not enforced at all times, especially under benign or indifferent rulers; but it hung continually suspended over the heads of the Christians like a sword of Damocles.
The second persecution was that of Domitian, from 94 to 96. Tertullian calls him “a portion of Nero by his cruelty.” At first he only imposed heavy fines upon the wealthy Christians; but, thirsting for blood, he soon published more cruel edicts against them. Among his noblest victims were his cousin-german, Flavius Clemens, a man of consular dignity; John the Evangelist, who was thrown into a caldron of boiling oil (from which, however, he miraculously escaped unhurt); Andrew the Apostle, Dionysius the Areopagite, and Onesimus, S. Paul’s convert. Hegesippus, quoted by Eusebius in his _Ecclesiastical History_, has recorded a very interesting fact about the children of Jude, surnamed Thaddeus in the Gospel, telling us that, having confessed the faith under this reign, they were always honored in the church of Jerusalem, not alone as martyrs, but as relatives of Jesus Christ according to the flesh.
The third persecution was Trajan’s, from 97 to 116. In answer to a letter from his friend Pliny the Younger, who had command in Asia Minor, the emperor ordered that the Christians were not to be sought out, but that, if accused, and they remained obstinate in their faith, they were to be put to death. Under an appearance of mercy a large field was opened for the cruelty and exactions of Roman officials, which they were not slow to work. A single circumstance attests the severity of the persecution. This was that the Tiberian governor of Palestine wrote to the emperor complaining of the odious duty imposed upon him, since the Christians were forthcoming in greater numbers than he could, without tiring, have executed. The persecution was particularly severe in the East. Simeon, bishop of Jerusalem, Ignatius of Antioch, and the virgin Domitilla, who was related to three emperors, are among the more illustrious martyrs of the period.
