What, then, is the cause which has effected this mighty reality, as great as earth, as old as time, as marvellous as heaven, and whose name among us is Christianity? Nineteen hundred years ago, a little Child was borne in an obscure village of a poor country. His parents were poor and of no account; he himself lived a poor man, unknown and unnoticed, save in one or two instances plying during thirty years a lowly trade in a forgotten corner of the world. Of a sudden, however, he breaks silence: he preaches, all untaught as he seemed, a doctrine which earth had never before heard, and confirming it by signs earth had never before seen. Public attention is arrested: he becomes the hero of the hour, and parties spring up for and against him. Two years and a half go by in uneasy peace, but a day comes when his enemies get the upper hand, and denounce him to the civil tribunals of the country, whose cowardly justice, while declaring him to be innocent, yet allows popular prejudice and the threat of imperial displeasure to wrest from it an unwilling condemnation. The innovator is nailed to a gibbet, and his brief history, hardly three years old, seems for ever ended, and ended in what manner? By a sentence of capital punishment, and a memory left stained with ignominy by the hand of the public executioner.

Here, then, is the cause we seek: A Jew! a poor, unknown, untaught Jew! a Jew condemned to a shameful death by the justice of his country, and executed on the public road among other malefactors; a Jew, and, if we dare to say the word, a felon!

Listen and weigh well that which you shall hear. You have seen the cause, you have seen the effect. Between the two rises the great question. How could such a cause produce such an effect? This we purpose to examine in a few words:

There are three explanations from which your choice may be made, and which pretend to connect a cause so radically powerless with an effect so immeasurably disproportionate. They are these: Either mankind has believed for two thousand years and actually believes in Christianity without sufficient reason, without adequate proof. In that case, humanity is mad, and for twenty centuries has been so, and I myself, who am speaking to you, am out of my senses.

Or else mankind believes with fully adequate proof, perfectly calculated to convince it, and yet what it believes is false. In that case, God has deceived us during twenty, forty, sixty centuries, since the beginning of the world. In that case, Providence is a mockery, and its sway over the universe has been from the very first hour of creation but one long mystification, one scornful derision of our human reason. Or again, if you cannot believe either that mankind has mistaken God, or that God has deceived mankind, there is but one hypothesis left, namely, that Jesus Christ is God!

In order that you may choose more deliberately between these three possibilities, it will be necessary to afford them fuller development. The first of these compels you to infer that mankind for the last two thousand years has been bereft of reason, and that at the present moment a considerable portion of it, myself included, is in a hopeless state of insanity.

This may seem to you an exaggerated proposition, got up simply to prop the weakness of an untenable argument, but it is nothing if not an absolute truth, most easy of demonstration. Let us suppose that to-morrow, the 18th of December of the year of grace 1865, there shall enter into this great capital, through one of its numerous gates and towards the dusk of evening, a poor and ragged beggar, the dust of his journey still upon him, and his ignorance of the language of the country painfully conspicuous. Let us suppose this man presenting himself before the populace, the magistracy, the priesthood, the army, and before the Emperor himself, and speaking to him thus: “Sire, a few years ago, your majesty was pleased to order the public execution, in a remote province of the Empire, of a Jew. This Jew was the Messiah, the Saviour, God himself! Therefore, O Cæsar! come down from your throne, bend your knee, be baptized, and confess your sins; for, mark it well, this crucified Jew is none other than your God.” What would you say, my brethren, to the man who should speak thus to-day? You would fitly account him a madman, and madder yet the people and the priesthood, the army and the monarch, who should believe in his wild words.

Well, then, this strange tale is a true one, it is a historical fact. One day, many ages ago, an old Jew, baptized by the name of Peter, entered, a beggar, ragged, and dust-begrimed, through one of the gates of the greatest capital of the mightiest empire of the world—ancient Rome.

In Rome, he actually preached the unheard-of sermon I have just quoted, and which, repeated in that form to-day, would cause only a burst of derision. Why did Rome not mock him? Why did the priesthood not hoot him? Why did Cæsar not scorn him? Why, on the contrary, did this beggar, with his rough staff and scrip, with his barbarous Latin sounding harshly on the ears of those who could yet remember the voice of Cicero on the rostrum—why did he shake the foundations of the mightiest empire of the world, and why, instead of provoking laughter, did the people pale and tremble before him in the Forum, the magistrates quail beneath their robes of office, the priesthood shrink affrighted to their doomed temples, and Nero, the emperor, forget to trust in his blood-stained purple? Why does the deserted Palatine look to-day upon the opposite hill of the Vatican, and behold there a dome whose summit may well be said to seek to scale the heavens—a dome that crowns a tomb, that of the beggar Peter, a tomb which, though but the fane of the dead, is nevertheless the centre of Europe and the world? For this tomb bears a throne at once the most ancient and the most sacred in Europe, the only one which represents an empire whose boundaries are the boundaries of the universe. And why all this? Only because Peter proved by signs and wonders, by miracles wrought both in life and in death, that he spoke indeed in the name of him whom heaven and earth obeyed, because he was their Maker. Because he wrought these signs, his word was believed. And I am free to confess that, had the men of his time believed in him without such an irrefragable proof of his mission, they would have been madmen indeed, and we, who are now the heirs of their faith, would have been only the successors to their folly. For two thousand years, I repeat it, the history of mankind would have been a long dream of insanity, an act of stupendous folly, and, as a climax to this incalculable confusion, there would have sprung from this folly the most incomprehensible of contradictions—wisdom and glory, light and virtue, civilization and progress—in a word, that great wonder which holds all lesser marvels within itself, namely, Christianity.

If I mistake not, your common sense has already set aside this hypothesis as untenable. We admit it, you may say to me; to make mankind believe in the—humanly speaking—unbelievable, there must have been proofs capable of proving and making certain, so to speak, the very impossible itself. We must admit it, unless we accuse the whole world of madness. But if Peter and the apostles, and all the preachers of the Gospel, confirmed their teaching by signs that were accounted miracles, might this not be explained by a chain of fortuitious coincidences, happy accidents, seeming miracles, which are every day elucidated by the progress of investigation until they utterly disappear in the full light of science? A discussion of the nature and essence of the Gospel miracles would be utterly out of place at this moment. I will therefore confine myself to this: if the miracles which, among outward causes, are the principal explanation of the world’s conversion to Christianity, are false, then it is no longer mankind unconsciously duped and led away, but Heaven itself, the deceiver and seducer, whom we must indignantly accuse.
