Something ought to be said of these Churches; though little is known except what is revealed by the fact, in itself of no slight value, that they had sustained two persecutions at the hands of the heathen government in the fourth and fifth centuries. One testimony is extant as early as the end of the second century, to the effect that in Parthia, Media, Persia, and Bactria there were Christians who "were not overcome by evil laws and customs."[292:2] In the early part of the fourth century, a bishop of Persia attended the Nicene Council, and about the same time Christianity is said to have pervaded nearly the whole of Assyria.[292:3] Monachism had been introduced there before the middle of the fourth century, and shortly after commenced that fearful persecution in which sixteen thousand Christians are said to have suffered. It lasted thirty years, and is said to have recommenced at the end of the Century. The second persecution lasted for at least another thirty years of the next, at the very time when the Nestorian troubles were in progress in the Empire. Trials such as these show the populousness as well as the faith of the Churches in those parts,--and the number of the Sees, for the names of twenty-seven Bishops are preserved who suffered in the former persecution. One of them was apprehended together with sixteen priests, nine deacons, besides monks and nuns of his diocese; another with twenty-eight companions, ecclesiastics or regulars; another with one hundred ecclesiastics of different orders; another with one hundred and twenty-eight; another with his chorepiscopus and two hundred and fifty of his clergy. Such was the Church, consecrated by the blood of so many martyrs, which immediately after its glorious confession fell a prey to the theology of Theodore; and which through a succession of ages manifested the energy, when it had lost the pure orthodoxy of Saints. 9.
