In truth, the question of the reality of the Jewish miracles must be carefully distinguished from that of the conversion of the Roman Empire. With the light that is furnished to us by modern investigations and habits of thought, we weigh the testimony of the Jewish writers; but most of the more judicious of modern apologists, considering the extreme credulity of the Jewish people, decline to make the question simply one of evidence, and occupy themselves chiefly in endeavouring to show that miracles are possible, that those recorded in the Biblical narratives are related in such a manner, and are so interwoven with the texture of a simple and artless narrative, as to carry with them an internal proof of their reality; that they differ in kind from later miracles, and especially that the character and destinies of Christianity are such as to render its miraculous origin antecedently probable. But in the ages when the Roman Empire was chiefly converted, all sound and discriminating historical investigation of the evidence of the early miracles was impossible, nor was any large use made of those miracles as proofs of the religion. The rhetorician Arnobius is probably the only one of the early apologists who gives, among the evidences of the faith, any prominent place to the miracles of Christ.(700) When evidential reasoning was employed, it was usually an appeal not to miracles, but to prophecy. But here again the opinions of the patristic age must be pronounced absolutely worthless. To prove that events had taken place in Judæa, accurately corresponding with the prophecies, or that the prophecies were themselves genuine, were both tasks far transcending the critical powers of the Roman converts. The wild extravagance of fantastic allegory, commonly connected with Origen, but which appears at a much earlier date in the writings of Justin Martyr and Irenæus, had thrown the interpretation of prophecy into hopeless confusion, while the deliberate and apparently perfectly unscrupulous forgery of a whole literature, destined to further the propagation either of Christianity as a whole, or of some particular class of tenets that had arisen within its border,(701) made criticism at once pre-eminently difficult and necessary. A long series of oracles were cited, predicting in detail the sufferings of Christ. The prophecies forged by the Christians, and attributed by them to the heathen Sibyls, were accepted as genuine by the entire Church, and were continually appealed to as among the most powerful evidences of the faith. Justin Martyr declared that it was by the instigation of dæmons that it had been made a capital offence to read them.(702) Clement of Alexandria preserved the tradition that St. Paul had urged the brethren to study them.(703) Celsus designated the Christians Sibyllists, on account of the pertinacity with which they insisted upon them.(704) Constantine the Great adduced them in a solemn speech before the Council of Nice.(705) St.
