The author is certainly the Celsus to whom Lucian dedicated his writing, “Alexander the False Prophet.” Of the religious opinions of Celsus we are able to form a tolerable conception from the work of Origen. “If the Christians only honoured One God,” says he,(75) “then the weapons of their controversy with others would not be so weak; but they show to a man, who appeared not long ago, an exaggerated honour, and are of opinion that they are not offending the Godhead, when they show to one of His servants the same reverence that they pay to God Himself.” Celsus acknowledges, with the Platonists, One only, eternal, spiritual God, who cannot be brought into union with impure matter, the world. All that concerns the world, he says, God has left to the dispensation of inferior spirits, which are the gods of heathendom. The welfare of mankind is at the disposal of these inferior gods, and men therefore do well to honour them in moderation; but the human soul is called to escape the chains of matter and strain after perfect purity; and this can only be done by meditation on the One, supreme, almighty God. “God,” says he,(76) “has not made man in His image, as Christians affirm; for God has not either the appearance of a man, nor indeed any visible form.” In the fourth Book he remarks, in opposition to the Christian doctrine of the Incarnation, “I will appeal to that which has been held as true in all ages,—that God is good, beautiful, blessed, and possesses in Himself all perfections. If He came down among men, He must have altered His nature; from a good God, He must have become bad; from beautiful, ugly; from blessed, unhappy; and His perfect Being would have become one of imperfection. Who can tolerate such a change? Only transitory things alter their conditions; the intransitory remain ever the same. Therefore it is impossible to conceive that God can have been transformed in such a manner.” It is remarkable that Celsus, living in the middle of the second century, and able to make inquiries of aged Jews whose lives had extended from the first century, should have been able to find out next to nothing about Jesus and his disciples, except what he read in the Gospels. This is proof that no traditions concerning Jesus had been preserved by the Jews, apart from those contained in the Gospels, Canonical and Apocryphal. Origen’s answer to Celsus is composed of eight Books. In the first Book a Jew speaks, who is introduced by Celsus as addressing Jesus himself; in the second Book this Jew addresses those of his fellow‐countrymen who have embraced Christianity; in the other six Books Celsus speaks for himself. Origen extracts only short passages from the work of Celsus, and then labours to demolish the force of the argument of the opponent of Christianity as best he can.
