From the day of Pentecost till the victory of Constantine the Great over Maxentius, embracing a period of about two hundred and eighty years, the Church underwent a series of ten persecutions unparalleled for atrocity in the annals of history. Every torture that malice could invent was resorted to, that every vestige of Christianity might be eradicated. _“__Christianos ad leones,__”__ the Christians to the lions_, was the popular war-cry. They were clothed in the skins of wild beasts, and thus exposed to be devoured by dogs. They were covered with pitch and set on fire to serve as lamp-posts to the streets of Rome. To justify such atrocities, and to smother all sentiments of compassion, these persecutors accused their innocent victims of the most appalling crimes. For three centuries the Christians were obliged to worship God in the secrecy of their chambers, or in the Roman catacombs, which are still preserved to attest the undying fortitude of the martyrs and the enormity of their sufferings. And yet Pagan Rome, before whose standard the mightiest nations quailed, was unable to crush the infant Church or arrest her progress. In a short time we find this colossal Empire going to pieces, and the Head of the Catholic Church dispensing laws to Christendom in the very city from which the imperial Cæsars had promulgated their edicts against Christianity! During the fifth and sixth centuries the Goths and Vandals, the Huns, Visigoths, Lombards and other immense tribes of Barbarians came down like a torrent from the North, invading the fairest portions of Southern Europe. They dismembered the Roman Empire and swept away nearly every trace of the old Roman civilization. They plundered cities, leveled churches and left ruin and desolation after them. Yet, though conquering for awhile, they were conquered in turn by submitting to the sweet yoke of the Gospel. And thus, as even the infidel Gibbon observes, “The progress of Christianity has been marked by two glorious and decisive victories over the learned and luxurious citizens of the Roman Empire and over the warlike Barbarians of Scythia and Germany, who subverted the empire and embraced the religion of the Romans.”(105) Mohamedanism took its rise in the seventh century in Arabia, and made rapid conquests in Asia. In the fifteenth century Constantinople was captured by the followers of the false prophet, who even threatened to subject all Europe to their sway. For nine centuries Mohamedanism continued to be a standing menace to christendom, till the final issue came when it was to be decided once for all whether Christianity and civilization on the one hand, or Mohamedanism and infidelity on the other, should rule the destinies of Europe and the world.
