Sorcery and star-worship are both against the law
Further, being somewhat confused, and not having looked carefully into what concerns this subject, he supposed that the Jews were led on by the spells used in magic and sorcery to worship the angels in heaven, because of certain phantoms that appear, in answer to the spells, to those who chant them. He did not see that this too, in those who did such things, was done against the law, which says: “You shall not follow mediums, and you shall not attach yourselves to enchanters, so as to be defiled by them: I am the Lord your God” (Leviticus 19:31).
He ought, then, since he regards the Jews as keeping the law and says that they are the ones who live by the law, either not to have attributed these things to the Jews at all, or, if he attributed them, to have shown that it was the Jews who broke the law who did such things. But again: just as those break the law who, blinded and dreaming through dim phantoms, worship by sorcery beings somewhere in the dark, bowing down to those said to draw near and to others of that kind, so too those who sacrifice to the sun, the moon and the stars break the law most thoroughly. And it was not consistent for the same man to say that the Jews are on their guard against worshipping the sun, the moon and the stars, and yet are not on their guard against such worship where heaven and angels are concerned.

Ἔτι δ᾿ ὑποσυγκεχυμένος καὶ μὴ ἐπιμελῶς ἰδὼν τὰ κατὰ τὸν τόπον ᾠήθη ἀπὸ τῶν ἐν μαγγανείαις καὶ γοητείαις ἐπῳδῶν προτραπέντας Ἰουδαίους ἔκ τινων κατὰ τὰς ἐπῳδὰς φασμάτων ἐπιφαινομένων τοῖς ἐπᾴδουσι προσκυνεῖν τοὺς ἐν οὐρανῷ ἀγγέλους. οὐ συνιδὼν ὅτι καὶ τοῦτο παρὰ τὸν νόμον τοῖς γε ταῦτα ποιοῦσιν ἐγίνετο λέγοντα· „οὐκ ἐπακολουθήσετε ἐγγαστριμύθοις, καὶ τοῖς ἐπαοιδοῖς οὐ προσκολληθήσεσθε ἐκμιανθῆναι ἐν αὐτοῖς· ἐγὼ κύριος ὁ θεὸς ὑμῶν.“ ἐχρῆν οὖν ἢ μηδ᾿ ὅλως ταῦτ᾿ εἰς Ἰουδαίους ἀναφέρειν τὸν τηροῦντα Ἰουδαίους ὡς φυλάσσοντας τὸν νόμον καὶ λέγοντα αὐτοὺς εἶναι τοὺς κατὰ τὸν νόμον βιοῦντας, ἢ ἀναφέροντα παραστῆσαι ὅτι τὰ τοιαῦτα οἱ παρανομοῦντες Ἰουδαῖοι ἐποίουν. ἀλλὰ πάλιν ὥσπερ παρανομοῦσιν οἱ τοὺς ἐν σκότῳ που καὶ ἐκ γοητείας θρησκεύοντες. τυφλώττοντες καὶ δι᾿ ἀμυδρῶν φασμάτων ὀνειρώττοντες, προσκυνοῦντες τοὺς ἐγχρίμπτειν λεγομένους καὶ τοῖς τοιούτοις· οὕτως καὶ οἱ ἡλίῳ καὶ σελήνῃ καὶ ἄστροις θύοντες εὖ μάλα παρανομοῦσι. καὶ οὐκ ἦν κατὰ τὸν αὐτὸν λέγειν Ἰουδαίους καὶ φυλαττομένους προσκυνεῖν ἥλιον καὶ σελήνην καὶ ἄστρα, καὶ τὸ τοιοῦτον μὴ φυλαττομένους ἐπὶ οὐρανοῦ καὶ ἀγγέλων.
