Origen of Alexandria, Against Celsus 41
We decided to address each of the objections he raises, to the best of our ability, so that we would not appear to be dodging an answer out of helplessness. In doing so, we paid attention not to the natural logic and sequence of the matters themselves, but to the order in which they appear in his book. Come, then, let us see what he says as he slanders the Holy Spirit, which the Savior saw in bodily form like a dove. A Jew is the one speaking these things to him — the very one to whom we acknowledge Jesus as our Lord. 'When you were being baptized by John,' the Jew says, 'you claim that a phantom bird descended on you from the air.' Then the Jew who is with him asks, 'Who is the credible witness who saw the phantom? Or who heard a voice from heaven declaring you to be the Son of God? — apart from the fact that you yourself say so and produce one of your own companions who was bribed.'
Greek
Ἵνα δὲ μὴ δοκῶμεν ἑκόντες διὰ τὸ ἀπορεῖν ἀπαντήσεως ὑπερβαίνειν αὐτοῦ τὰ κεφάλαια, ἐκρίναμεν ἕκαστον κατὰ δύναμιν λῦσαι τῶν ὑπ᾿ αὐτοῦ προτιθεμένων. φροντίσαντες οὐ τοῦ ἐν τῇ φύσει τῶν πραγμάτων εἱρμοῦ καὶ ἀκολουθίας ἀλλὰ τῆς τάξεως τῶν ἐν τῇ βίβλῳ αὐτοῦ ἀναγεγραμμένων. φέρ᾿ οὖν ἴδωμεν, τί ποτε καὶ λέγει διαβάλλων τὸ οἷον σωματικῶς ἑωραμένον ὑπὸ τοῦ σωτῆρος πνεῦμα ἅγιον εἴδει περιστερᾶς· ἔστι δ᾿ ὁ Ἰουδαῖος αὐτῷ ἔτι ταῦτα λέγων, πρὸς ὃν ὁμολογοῦμεν εἶναι κύριον ἡμῶν τὸν Ἰησοῦν· λουομένῳ, φησὶ, σοὶ παρὰ τῷ Ἰωάννῃ φάσμα ὄρνιθος ἐξ ἀέρος λέγεις ἐπιπτῆναι. εἶτα πυνθανόμενος ὁ παρ᾿ αὐτῷ Ἰουδαῖός φησι· τίς τοῦτο εἶδεν ἀξιόχρεως μάρτυς τὸ φάσμα, ἢ τίς ἤκουσεν ἐξ οὐρανοῦ φωνῆς εἰσποιούσης σε υἱὸν τῷ θεῷ; πλὴν ὅτι σὺ φῂς καί τινα ἕνα ἐπάγῃ τῶν μετὰ σοῦ κεκολασμένων.
