§ 23.2. =Worshippers of an Ass= (Asinarii) was a term of reproach that was originally and from early times applied to the Jews. They now sought to have it transferred to the Christians. Tertullian tells of a picture publicly exhibited in Carthage which represented a man clothed in a toga, with the ears and hoof of an ass, holding a book in his hand, and had this inscription: _Deus Christianorum Onochoetes_. This name is variously read. If read as ὄνου χοητής it means _asini sacerdos_. Alongside of this we may place the picture, belonging probably to the third century, discovered in A.D. 1858 scratched on a wall among the ruins of a school for the imperial slaves, that were then excavated. It represents a man with an ass’s head hanging on a cross, and beneath it the caricature of a worshipper with the words written in a schoolboy’s hand; Alexamenos worships God (A. σεβετε θεον); evidently the derision of a Christian youth by a pagan companion. The scratching on another wall gives us probably the answer of the Christian: _Alexamenos fidelis_. § 23.3. =Polemic properly so-called.=-- (a) The Λόγος ἀληθής of =Celsus= is in great part preserved in the answer of Origen (§ 31, 5). He identifies the author with that Celsus to whom Lucian dedicated the little work _Alexander or Pseudomantis_ in which he so extols the philosophy of Epicurus that it seems he must be regarded as an Epicurean. Since, however, the philosophical standpoint of our Celsus is that of a Platonist the assumption of the identity of the two has been regarded as untenable. But even our Celsus does not seem to have been a pure Platonist but an Eclectic, and as such might also show a certain measure of favour to the philosophy of Epicurus. Their age is at least the same. Lucian wrote that treatise soon after A.D. 180, and according to Keim, the Λόγος ἀληθής was probably composed about A.D. 178. Almost everything that modern opponents down to our own day have advanced against the gospel history and doctrine is found here wrought out with original force and subtlety, inspired with burning hatred and bitter irony, and highly spiced with invective, mockery, and wit. First of all the author introduces a Jew who repeats the slanders current among the Jews, representing Jesus as a vagabond impostor, His mother as an adulteress, His miracles and resurrection as lying fables; then enters a heathen philosopher who proves that both Judaism and Christianity are absurd; and finally, the conditions are set forth under which alone the Christians might claim indulgence: the abandonment of their exclusive attitude toward the national religion and the recognition of it by their taking part in the sacrifices appointed by the state.[29]
