Justin Martyr, Apologia secunda

Εἰ δέ τινα ὑπέλθοι καὶ ἡ ἔννοια αὕτη ὅτι, εἰ θεὸν ὡμολογοῦμεν βοηθόν, οὐκ ἄν, ὡς λέγομεν, ὑπὸ ἀδίκων ἐκρατούμεθα καὶ ἐτιμωρούμεθα, καὶ τοῦτο διαλύσω. Ὁ θεὸς τὸν πάντα κόσμον ποιήσας καὶ τὰ ἐπίγεια ἀνθρώποις ὑποτάξας καὶ τὰ οὐράνια στοιχεῖα εἰς αὔξησιν καρπῶν καὶ ὡρῶν μεταβολὰς κοσμήσας καὶ θεῖον τούτοις νόμον τάξας, ἃ καὶ αὐτὰ δι᾿ ἀνθρώπους φαίνεται πεποιηκώς, τὴν μὲν τῶν ἀνθρώπων καὶ τῶν ὑπὸ τὸν οὐρανὸν πρόνοιαν ἀγγέλοις, οὓς ἐπὶ τούτοις ἔταξε, παρέδωκεν. Οἱ δ᾿ ἄγγελοι, παραβάντες τήνδε τὴν τάξιν, γυναικῶν μίξεσιν ἡττήθησαν καὶ παῖδας ἐτέκνωσαν, οἵ εἰσιν οἱ λεγόμενοι δαίμονες. Καὶ προσέτι λοιπὸν τὸ ἀνθρώπειον γένος ἑαυτοῖς ἐδούλωσαν· τὰ μὲν διὰ μαγικῶν γραφῶν, τὰ δὲ διὰ φόβων καὶ τιμωριῶν, ὧν ἐπέφερον, τὸ δὲ διὰ διδαχῆς θυμάτων καὶ θυμιαμάτων καὶ σπονδῶν, ὧν ἐνδεεῖς γεγόνασι μετὰ τὸ πάθεσιν ἐπιθυμιῶν δουλωθῆναι· καὶ εἰς ἀνθρώπους φόνους, πολέμους, μοιχείας, ἀπολασίας καὶ πᾶσαν κακίαν ἔσπειραν. Ὅθεν καὶ ποιηταὶ καὶ μυθολόγοι, ἀγνοοῦντες τοὺς ἀγγέλους καὶ τοὺς ἐξ αὐτῶν γεννηθέντας δαίμονας ταῦτα πρᾶξαι εἰς ἄῤῥενας καὶ θηλείας καὶ πόλεις καὶ ἔθνη, ἅπερ συνέγραψαν, εἰς αὐτὸν τὸν θεὸν καὶ τοὺς ὡς ἀπ᾿ αὐτοῦ σπορᾷ γενομένους υἱοὺς καὶ τῶν λεχθέντων ἐκείνου ἀδελφῶν καὶ τέκνων ὁμοίως τῶν ἀπ᾿ ἐκείνων, Ποσειδῶνος καὶ Πλούτωνος, ἀνήνεγκαν. Ὀνόματι γὰρ ἕκαστον, ὅπερ ἕκαστος ἑαυτῷ τῶν ἀγγέλων καὶ τοῖς τέκνοις ἔθετο, προσηγόρευσαν.

If this thought too should steal into anyone’s mind, that if we acknowledged God as our helper we would not, as we say [we are], be overpowered and punished by unjust men, I will resolve this too. God, having made the whole world, and having subjected earthly things to men, and having ordered the heavenly elements for the growth of crops and the changes of the seasons, and having laid down a divine law for them, things which he evidently made, they too, for the sake of men, handed over the care of men and of things beneath heaven to angels, whom he set over these. But the angels transgressed this order, were overcome by intercourse with women, and begot children, who are those called demons. And besides, they then enslaved the human race to themselves, partly through magical writings, partly through the fears and punishments which they inflicted, and partly through teaching sacrifices and incense and libations, of which they had come to stand in need after they were enslaved to the passions of desire; and among men they sowed murders, wars, adulteries, licentiousness and every vice. Hence poets and mythologists, not knowing that it was the angels and the demons begotten from them who did these things to males and females and cities and nations, which they recorded, ascribed them to God himself and to those born as sons, so to speak, from his seed, and to his so-called brothers, Poseidon and Pluto, and likewise to the children born from them. For they called each by the name which each of the angels had given to himself and to his children.
