As we have said, the military domination of Rome had brought about universal peace, and had generated a sentiment of brotherhood among the vanquished nations. Things were, therefore, propitious for the rapid diffusion of the newly-established—the Christian—principle throughout the empire. It spread from Syria through all Asia Minor, and successively reached Cyprus, Greece, Italy, eventually extending westward as far as Gaul and Britain.
Its propagation was hastened by missionaries who made it known in all directions. None of the ancient classical philosophies had ever taken advantage of such a means.
Political conditions determined the boundaries of the new religion. Its limits were eventually those of the Roman Empire; Rome, doubtfully the place of death of Peter, not Jerusalem, indisputably the place of the death of our Savior, became the religious capital. It was better to have possession of the imperial seven hilled city, than of Gethsemane and Calvary with all their holy souvenirs.
IT GATHERS POLITICAL POWER. For many years Christianity manifested itself as a system enjoining three things—toward God veneration, in personal life purity, in social life benevolence. In its early days of feebleness it made proselytes only by persuasion, but, as it increased in numbers and influence, it began to exhibit political tendencies, a disposition to form a government within the government, an empire within the empire. These tendencies it has never since lost. They are, in truth, the logical result of its development. The Roman emperors, discovering that it was absolutely incompatible with the imperial system, tried to put it down by force. This was in accordance with the spirit of their military maxims, which had no other means but force for the establishment of conformity.
In the winter A.D. 302-'3, the Christian soldiers in some of the legions refused to join in the time-honored solemnities for propitiating the gods. The mutiny spread so quickly, the emergency became so pressing, that the Emperor Diocletian was compelled to hold a council for the purpose of determining what should be done. The difficulty of the position may perhaps be appreciated when it is understood that the wife and the daughter of Diocletian himself were Christians. He was a man of great capacity and large political views; he recognized in the opposition that must be made to the new party a political necessity, yet he expressly enjoined that there should be no bloodshed. But who can control an infuriated civil commotion? The church of Nicomedia was razed to the ground; in retaliation the imperial palace was set on fire, an edict was openly insulted and torn down. The Christian officers in the army were cashiered; in all directions, martyrdoms and massacres were taking place. So resistless was the march of events, that not even the emperor himself could stop the persecution.
THE FIRST CHRISTIAN EMPEROR. It had now become evident that the Christians constituted a powerful party in the state, animated with indignation at the atrocities they had suffered, and determined to endure them no longer. After the abdication of Diocletian (A.D. 305), Constantine, one of the competitors for the purple, perceiving the advantages that would accrue to him from such a policy, put himself forth as the head of the Christian party. This gave him, in every part of the empire, men and women ready to encounter fire and sword in his behalf; it gave him unwavering adherents in every legion of the armies. In a decisive battle, near the Milvian bridge, victory crowned his schemes. The death of Maximin, and subsequently that of Licinius, removed all obstacles. He ascended the throne of the Caesars—the first Christian emperor.
Place, profit, power—these were in view of whoever now joined the conquering sect. Crowds of worldly persons, who cared nothing about its religious ideas, became its warmest supporters. Pagans at heart, their influence was soon manifested in the paganization of Christianity that forthwith ensued. The emperor, no better than they, did nothing to check their proceedings. But he did not personally conform to the ceremonial requirements of the Church until the close of his evil life, A.D. 337.
TERTULLIAN'S EXPOSITION OF CHRISTIANITY. That we may clearly appreciate the modifications now impressed on Christianity—modifications which eventually brought it in conflict with science—we must have, as a means of comparison, a statement of what it was in its purer days. Such, fortunately, we find in the "Apology or Defense of the Christians against the Accusations of the Gentiles," written by Tertullian, at Rome, during the persecution of Severus. He addressed it, not to the emperor, but to the magistrates who sat in judgment on the accused. It is a solemn and most earnest expostulation, setting forth all that could be said in explanation of the subject, a representation of the belief and cause of the Christians made in the imperial city in the face of the whole world, not a querulous or passionate ecclesiastical appeal, but a grave historical document. It has ever been looked upon as one of the ablest of the early Christian works. Its date is about A.D. 200.
With no inconsiderable skill Tertullian opens his argument. He tells the magistrates that Christianity is a stranger upon earth, and that she expects to meet with enemies in a country which is not her own. She only asks that she may not be condemned unheard, and that Roman magistrates will permit her to defend herself; that the laws of the empire will gather lustre, if judgment be passed upon her after she has been tried but not if she is sentenced without a hearing of her cause; that it is unjust to hate a thing of which we are ignorant, even though it may be a thing worthy of hate; that the laws of Rome deal with actions, not with mere names; but that, notwithstanding this, persons have been punished because they were called Christians, and that without any accusation of crime.
He then advances to an exposition of the origin, the nature, and the effects of Christianity, stating that it is founded on the Hebrew Scriptures, which are the most venerable of all books. He says to the magistrates: "The books of Moses, in which God has inclosed, as in a treasure, all the religion of the Jews, and consequently all the Christian religion, reach far beyond the oldest you have, even beyond all your public monuments, the establishment of your state, the foundation of many great cities—all that is most advanced by you in all ages of history, and memory of times; the invention of letters, which are the interpreters of sciences and the guardians of all excellent things. I think I may say more—beyond your gods, your temples, your oracles and sacrifices. The author of those books lived a thousand years before the siege of Troy, and more than fifteen hundred before Homer." Time is the ally of truth, and wise men believe nothing but what is certain, and what has been verified by time. The principal authority of these Scriptures is derived from their venerable antiquity. The most learned of the Ptolemies, who was surnamed Philadelphus, an accomplished prince, by the advice of Demetrius Phalareus, obtained a copy of these holy books. It may be found at this day in his library. The divinity of these Scriptures is proved by this, that all that is done in our days may be found predicted in them; they contain all that has since passed in the view of men.
