I suppose it will not be denied that the soldiers, by whose aid Constantine achieved this great victory, were themselves professedly converts to Christianity; and Christianity as it had existed in the times of the recent persecutions was not likely to allure men to the profession of arms. I think, therefore, we may fairly assume, that, if the imperial armies were to any considerable extent—and it must have been ex hypothesi to a prevailing extent—composed of Christians, Christianity had made at least equal progress in the ranks of civil life. The one may be taken as the measure of the other; though we might fairly suppose, both from the principles and habits of the Christians, that they would be found in civil life in a larger ratio. The camp was not precisely the place for them; the Gospel might find them there, it rarely sent them. So that the question returns, How came it to pass that the bulk of the armies which "conquered the empire for Christianity" came to be Christians,—at least in name and profession?

"Ah!" you will say, "in name,—but they were strange Christians who became soldiers." Very true; and it makes my argument the stronger. Mere professors of a religious system only follow in the wake of its triumphs. When those who do not care much for a system profess and embrace it, depend upon it, it has largely triumphed. To suppose, therefore, that Constantine conquered the empire for Christianity, while we admit that the army was already Christian, is very like getting rid of the objection in the way the Irishman proposed to get rid of some superfluous cart-loads of earth. "Let us dig a hole," said he, "and put it in." It is much the same here.

Constantine became a convert, perhaps from conviction, but certainly rather late. Supposing him a political convert, as many have done, it could only be because he saw that Christianity had done its work to such an extent as to render it more probable that it would assist him than that he could assist it. This induced him to take it under the wing of his patronage. And on such a theory, what but such a conviction could have justified him in the attempt for a moment? How could he be fool enough to add to the difficulties of his position—a candidate for empire—the stupendous difficulty of forcing upon his unwilling or indifferent subjects a religion which by supposition they were any thing but prepared to receive? If the prospects of Christianity had not already decided the question for him, so far from receiving credit for political sagacity, as he ever has done, he would deserve rather to be considered an absolute idiot!

Again; is it not plain from history in general, and must we not infer it from the nature of the case a priori, that Christianity must in some fashion have conquered its millions before Constantine or any other man was likely to attempt to conquer the empire for Christianity, or to succeed in so doing if he had? Is there an instance on record of a people suddenly, at a moment's notice, changing its religion, or rather—for this is the true representation—of many different nations changing their many different religions at the simple command of their sovereign, and he too an upstart? In two cases, and in only two, it may be done; first, by an unsparing use of the sword, the brief, simple alternative of Mahomet, Death or the Koran; the other, when the new form of belief has converted the bulk or a large portion of the nation; of which, in this case, the conversion of the army is a tolerably significant indication.

But again; if it be said that the people, or rather the many different nations, abandoned their religions out of complaisance to their sovereign, I answer, Why do we not see the same thing repeated when Julian wished to reverse the experiment? They were not so pliant then; then was it seen very dearly that the people were, as in every other case, unwilling, as regards their religion, to be mere puppets in the hands of their governors. He was animated by at least as strong a hatred of Christianity as Constantine by a love of it. Yet we see all the way through, that there was not a chance of success for him.

"But there were some persecutions," you will say, "by Constantine." True, but they were so trifling compared with what would have been required had the conversion of an unbelieving and refractory empire depended on such means, that few who read the history of religious revolutions will believe that they were the cause of the change. Every thing shows that a vast preceding moral revolution in the empire is the only sufficient explanation of so sudden an event. Gibbon himself admits Constantine's tolerant disposition.

"But," it may be said, "the old heathenism was worn out and effete; no one thought it worth his while to stand up in its defence."

I answer, first, it seems to have been sufficiently loved, or at least Christianity was sufficiently hated, to insure frequent and sanguinary persecutions of the latter, almost up to the eve of Constantine's accession. Secondly, you are to consider that, though in the schools of philosophers, in the Epicurean or sceptical atmosphere of the luxurious capital and other great cities, there was unquestionably a numerous party to whom the old superstition was a laughing-stock, there were vast multitudes to whom it was still, in its various forms, a thing of power. You are to recollect that the Roman empire was made up of many nations, each with a different mode of religion, and to suppose that these different religions had ceased to exercise the usual influence on vast multitudes of the people would be mere delusion. If they were surrendered at last so easily, it could only be because a great party—antagonistic to each—had been silently forming in each nation, and undermining the power of the popular superstitions. But, thirdly, if the representation were true, to what can so singular a phenomenon—this simultaneous decay of different religions, this epidemic pestilence amongst the gods of the Pantheon —be ascribed, but to the previous influence of Christianity, and its extensive conquests? And, fourthly, supposing this not the case, and yet that the indifference in question existed, this indifference to the old systems of religion would not presuppose equal indifference to new, or induce the people to embrace them at the mere bidding of their new master. If this were so, we ought to see the same phenomenon repeated in the case of Julian. If, in their presumed indifference to the old and the new, they listened to Constantine when he commanded them to become Christians, why did not they manifest an equally compliant temper when the Apostate enjoined them to become heathens, and like Constantine, gave them both precept and example?

But look at the historic evidence on the subject long before the establishment of Christianity. Is it possible for any candid person to read the Epistle of Pliny to Trajan, and not see in that alone, after making every deduction for any supposed bias under which the letter may have been written (though, in fact, it is difficult to suppose any bias that would not rather lead the writer to diminish the number of the Christians than to exaggerate it),—is it possible, I say, to read that singular state paper, and not feel that the new religion had made prodigious progress in that remote province? and that, a fortiori, if in Bithynia it had conquered its thousands of proselytes, in other and more favored provinces it must have gained its tens of thousands? To me the letter of Pliny speaks volumes; and if so much could be said at so early a period as A. D. 107, what was the state of things two centuries later?

Precisely the same conclusion must be arrived at if we consult the uniform tone of the Christian apologists, from Justin Martyr to Minucius Felix. Making here, again, what deductions you please for the fervid eloquence and rhetorical exaggerations of such a man as Tertullian, it is too much to suppose even his "African" impetuosity would have ventured, not merely on the virulent invective, the bold taunts, with which he everywhere assails the popular superstitions, but on such strong assertions of the triumphant progress of the upstart religion, unless there had been obvious approximation to truth in his statements. "We were but of yesterday," says he, "and we have filled your cities, islands, towns, and assemblies; the camp, the senate, the palace, and the forum swarm with converts to Christianity." Apologist for Christianity! Unless these words had been enforced by very much of truth, he would have made Christianity simply ridiculous; and Christians would have been necessitated to apologize for their mad apologist.
