Against Celsus 5.54

Then he answers himself as he wishes; yet he is not reported to have come to the human race alone, so that even those who, on the pretext of the teaching of the name of Jesus, have departed from the Creator as an inferior being and gone over to some supposedly higher God, Father of the one who came, say that even before him some came to the human race from the Creator. But since we examine the subject with love of truth, we will say that Apelles, the pupil of Marcion, who became the father of a certain heresy and considered the writings of the Jews a myth, says that this one alone came to the human race. Not even against him, then, who says that Jesus alone came to human beings from God, could Celsus reasonably bring the claim that others too have come, since Apelles, as we said before, disbelieves the Jewish Scriptures that tell of more marvellous things; and much less will he accept what Celsus seems to have set down having misheard it from what is written in Enoch. No one, then, convicts us of lying and contradicting ourselves, both that our Saviour alone came and that many others have often come. And in examining the angels who have come to human beings, Celsus sets down, very confusedly, what came to him indistinctly from what is written in Enoch; he does not seem to have read these writings himself, nor to know that the books inscribed with the name of Enoch are not at all accepted as divine in the churches. Hence he might be thought to have thrown out the "sixty or seventy together" who came down and became wicked.
