The progress of Christianity was not confined to the Roman empire; and according to the primitive fathers, who interpret facts by prophecy, the new religion, within a century after the death of its divine Author, had already visited every part of the globe. “There exists not,” says Justin Martyr, “a people, whether Greek or Barbarian, or any other race of men, by whatsoever appellation or manners they may be distinguished, however ignorant of arts or agriculture, whether they dwell under tents, or wander about in covered wagons, among whom prayers are not offered up in the name of a crucified Jesus to the Father and Creator of all things.” 177 But this splendid exaggeration, which even at present it would be extremely difficult to reconcile with the real state of mankind, can be considered only as the rash sally of a devout but careless writer, the measure of whose belief was regulated by that of his wishes. But neither the belief nor the wishes of the fathers can alter the truth of history. It will still remain an undoubted fact, that the barbarians of Scythia and Germany, who afterwards subverted the Roman monarchy, were involved in the darkness of paganism; and that even the conversion of Iberia, of Armenia, or of Aethiopia, was not attempted with any degree of success till the sceptre was in the hands of an orthodox emperor. 178 Before that time, the various accidents of war and commerce might indeed diffuse an imperfect knowledge of the gospel among the tribes of Caledonia, 179 and among the borderers of the Rhine, the Danube, and the Euphrates. 180 Beyond the last-mentioned river, Edessa was distinguished by a firm and early adherence to the faith. 181 From Edessa the principles of Christianity were easily introduced into the Greek and Syrian cities which obeyed the successors of Artaxerxes; but they do not appear to have made any deep impression on the minds of the Persians, whose religious system, by the labors of a well disciplined order of priests, had been constructed with much more art and solidity than the uncertain mythology of Greece and Rome. 182
From this impartial though imperfect survey of the progress of Christianity, it may perhaps seem probable, that the number of its proselytes has been excessively magnified by fear on the one side, and by devotion on the other. According to the irreproachable testimony of Origen, 183 the proportion of the faithful was very inconsiderable, when compared with the multitude of an unbelieving world; but, as we are left without any distinct information, it is impossible to determine, and it is difficult even to conjecture, the real numbers of the primitive Christians. The most favorable calculation, however, that can be deduced from the examples of Antioch and of Rome, will not permit us to imagine that more than a themselves under the banner of the cross before the important conversion of Constantine. But their habits of faith, of zeal, and of union, seemed to multiply their numbers; and the same causes which contributed to their future increase, served to render their actual strength more apparent and more formidable.
Such is the constitution of civil society, that whilst a few persons are distinguished by riches, by honors, and by knowledge, the body of the people is condemned to obscurity, ignorance and poverty. The Christian religion, which addressed itself to the whole human race, must consequently collect a far greater number of proselytes from the lower than from the superior ranks of life. This innocent and natural circumstance has been improved into a very odious imputation, which seems to be less strenuously denied by the apologists, than it is urged by the adversaries, of the faith; that the new sect of Christians was almost entirely composed of the dregs of the populace, of peasants and mechanics, of boys and women, of beggars and slaves, the last of whom might sometimes introduce the missionaries into the rich and noble families to which they belonged. These obscure teachers (such was the charge of malice and infidelity) are as mute in public as they are loquacious and dogmatical in private. Whilst they cautiously avoid the dangerous encounter of philosophers, they mingle with the rude and illiterate crowd, and insinuate themselves into those minds, whom their age, their sex, or their education, has the best disposed to receive the impression of superstitious terrors. 184
This unfavorable picture, though not devoid of a faint resemblance, betrays, by its dark coloring and distorted features, the pencil of an enemy. As the humble faith of Christ diffused itself through the world, it was embraced by several persons who derived some consequence from the advantages of nature or fortune. Aristides, who presented an eloquent apology to the emperor Hadrian, was an Athenian philosopher. 185 Justin Martyr had sought divine knowledge in the schools of Zeno, of Aristotle, of Pythagoras, and of Plato, before he fortunately was accosted by the old man, or rather the angel, who turned his attention to the study of the Jewish prophets. 186 Clemens of Alexandria had acquired much various reading in the Greek, and Tertullian in the Latin, language. Julius Africanus and Origen possessed a very considerable share of the learning of their times; and although the style of Cyprian is very different from that of Lactantius, we might almost discover that both those writers had been public teachers of rhetoric. Even the study of philosophy was at length introduced among the Christians, but it was not always productive of the most salutary effects; knowledge was as often the parent of heresy as of devotion, and the description which was designed for the followers of Artemon, may, with equal propriety, be applied to the various sects that resisted the successors of the apostles. “They presume to alter the Holy Scriptures, to abandon the ancient rule of faith, and to form their opinions according to the subtile precepts of logic. The science of the church is neglected for the study of geometry, and they lose sight of heaven while they are employed in measuring the earth. Euclid is perpetually in their hands. Aristotle and Theophrastus are the objects of their admiration; and they express an uncommon reverence for the works of Galen. Their errors are derived from the abuse of the arts and sciences of the infidels, and they corrupt the simplicity of the gospel by the refinements of human reason.” 187
Nor can it be affirmed with truth, that the advantages of birth and fortune were always separated from the profession of Christianity. Several Roman citizens were brought before the tribunal of Pliny, and he soon discovered, that a great number of persons of every order of men in Bithynia had deserted the religion of their ancestors. 188 His unsuspected testimony may, in this instance, obtain more credit than the bold challenge of Tertullian, when he addresses himself to the fears as well as the humanity of the proconsul of Africa, by assuring him, that if he persists in his cruel intentions, he must decimate Carthage, and that he will find among the guilty many persons of his own rank, senators and matrons of nobles’ extraction, and the friends or relations of his most intimate friends. 189 It appears, however, that about forty years afterwards the emperor Valerian was persuaded of the truth of this assertion, since in one of his rescripts he evidently supposes, that senators, Roman knights, and ladies of quality, were engaged in the Christian sect. 190 The church still continued to increase
