Who says he came alone
Then he answers himself as he pleases. But in fact Christ is not recorded as the only one to have visited the human race. So true is this that even those who, using the teaching of the name of Jesus as a pretext, have turned away from the Creator as lesser and gone over to some God as greater and as Father of the one who came, say that even before him some visited the human race from the Creator.
But since we are examining this passage with a love of truth, we will say that Apelles, the disciple of Marcion, who became the father of a certain heresy and regarded the writings of the Jews as myth, says that this one alone has visited the human race. So not even against him, though he says that Jesus alone has come from God to men, could Celsus reasonably bring the argument that others too have come; for, as we said before, Apelles does not believe the Jewish Scriptures, which report rather marvellous things. Much less will he accept what Celsus seems to have set down after mishearing what is written in Enoch.
No one, then, convicts us of lying and of asserting contradictory things, as though we said both that our Saviour alone came and that many others have often come. But in his inquiry into the angels who have come to men, Celsus sets down in great confusion what reached him indistinctly from what is written in Enoch. He does not appear even to have read these writings, nor to have known that in the churches the books inscribed with Enoch's name are not generally received as divine. That is why he might be thought to have tossed out the claim that sixty or seventy came down together, having become wicked.
Greek
Εἶτ᾿ ἀπαντᾷ ἑαυτῷ, ὡς βούλεται· οὕτω δ᾿ οὐ μόνος ἱστόρηται ἐπιδεδημηκέναι τῷ γένει τῶν ἀνθρώπων. ὡς καὶ τοὺς προφάσει τῆς διδασκαλίας τοῦ ὀνόματος Ἰησοῦ ἀποστάντας τοῦ δημιουργοῦ ὡς ἐλάττονος καὶ προσεληλυθότας ὡς κρείττονί τινι θεῷ καὶ πατρὶ τοῦ ἐπιδημήσαντος φάσκειν ὅτι καὶ πρὸ τούτου ἐπεδήμησάν τινες ἀπὸ τοῦ δημιουργοῦ τῷ γένει τῶν ἀνθρώπων. ἐπεὶ δὲ φιλαλήθως τὰ κατὰ τὸν τόπον ἐξετάζομεν, φήσομεν ὅτι ὁ Μαρκίωνος γνώριμος Ἀπελλῆς, αἱρέσεώς τινος γενόμενος πατὴρ καὶ μῦθον ἡγούμενος εἶναι τὰ Ἰουδαίων γράμματα. φησὶν ὅτι μόνος οὗτος ἐπιδεδήμηκε τῷ γένει τῶν ἀνθρώπων. οὐδὲ πρὸς ἐκεῖνον οὖν, λέγοντα μόνον ἐπιδεδημηκέναι τὸν Ἰησοῦν ἀπὸ τοῦ θεοῦ τοῖς ἀνθρώποις, εὐλόγως ἂν ὁ Κέλσος φέροι τὰ περὶ τοῦ καὶ ἄλλους ἐληλυθέναι, ἀπιστοῦντα. ὡς προείπομεν, ταῖς παραδοξότερα ἀπαγγελλούσαις Ἰουδαίων γραφαῖς· πολλῷ δὲ πλέον οὐ προσήσεται ἅπερ ἔοικε παρακούσας ἀπὸ τῶν ἐν τῷ Ἐνὼχ γεγραμμένων τεθεικέναι ὁ Κέλσος. οὐδεὶς τοίνυν ἐλέγχει ἡμᾶς ψευδομένους καὶ τὰ ἐναντία τιθέντας, ὅτι τε μόνος ἦλθεν ὁ σωτὴρ ἡμῶν καὶ ὅτι, ἐπεὶ ἄλλοι πολλοὶ πολλάκις ἐληλύθασι. πάνυ δὲ συγκεχυμένως ἐν τῇ περὶ τῶν ἐληλυθότων πρὸς ἀνθρώπους ἀγγέλων ἐξετάσει τίθησι τὰ ἀτρανώτως ἐλθόντα εἰς αὐτὸν ἀπὸ τῶν ἐν τῷ Ἐνὼχ γεγραμμένων· ἅτινα οὐδ᾿ αὐτὰ φαίνεται ἀναγνοὺς οὐδὲ γνωρίσας ὅτι ἐν ταῖς ἐκκλησίαις οὐ πάνυ φέρεται ὡς θεῖα τὰ ἐπιγεγραμμένα τοῦ Ἐνὼχ βιβλία· ὅθεν νομισθείη ἂν ἐῤῥιφέναι τὸ ὁμοῦ ἑξήκοντα ἢ ἑβδομήκοντα καταβεβηκέναι, κακοὺς γενομένους.
