Athenagoras, Plea for the Christians 9
If we had rested content with such thoughts, anyone would take our reasoning for merely human. But the voices of the prophets confirm our thoughts—and I assume even you, so devoted to learning and knowledge, are not unacquainted with Moses, Isaiah, Jeremiah, and the other prophets. Driven by the divine Spirit moving their minds, they uttered what the Spirit wrought in them, using them as a flutist breathes into an instrument. So what do they say? "The Lord our God; another will not be reckoned besides Him" (Isaiah 44:6). And again: "I am God first and after these things, and besides me there is no God" (Isaiah 46:9-10). Similarly: "Before me another God was not generated and after me there will not be one; I am God and there is no one besides me" (Isaiah 43:10-11). And concerning greatness: "The heaven is my throne, and the earth is the footstool of my feet. What kind of house will you build for me, or what is the place of my rest?" (Isaiah 66:1-2). I leave it to you, now that you have these books, to examine those prophecies more carefully, so that with proper reasoning you may set aside the prejudice against us.

Εἰ μὲν οὖν ταῖς τοιαύταις ἐννοίαις ἀπηρκούμεθα, ἀνθρωπικὸν ἄν τις εἶναι τὸν καθ᾿ ἡμᾶς ἐνόμισε λόγον. Ἐπεὶ δὲ αἱ φωναὶ τῶν προφητῶν πιστοῦσιν ἡμῶν τοὺς λογισμούς (νομίζω καὶ ὑμᾶς, φιλομαθεστάτους καὶ ἐπιστημονεστάτους ὄντας, οὐκ ἀνοήτους γεγονέναι οὔτε τῶν Μωσέως οὔτε τῶν Ἠσαΐου καὶ Ἱερεμίου καὶ τῶν λοιπῶν προφητῶν, οἳ κατ᾿ ἔκστασιν τῶν ἐν αὐτοῖς λογισμῶν κινήσαντος αὐτοὺς τοῦ θείου πνεύματος ἃ ἐνηργοῦντο ἐξεφώνησαν, συγχρησαμένου τοῦ πνεύματος ὡσεὶ καὶ αὐλητὴς αὐτὸν ἐμπνεύσαι), τί οὖν οὗτοι; Κύριος ὁ θεὸς ἡμῶν· οὐ λογισθήσεται ἕτερος πρὸς αὐτόν. Καὶ πάλιν· Ἐγὼ θεὸς πρῶτος καὶ μετὰ ταῦτα, καὶ πλὴν ἐμοῦ οὐκ ἔστι θεός. Ὁμοίως· Ἔμπροσθεν ἐμοῦ οὐκ ἐγένετο ἄλλος θεὸς καὶ μετ᾿ ἐμὲ οὐκ ἔσται· ἐγὼ ὁ θεὸς καὶ οὐκ ἔστι πάρεξ ἐμοῦ. Καὶ περὶ τοῦ μεγέθους· Ὁ οὐρανός μοι θρόνος, ἡ δὲ γῆ ὑποπόδιον τῶν ποδῶν μου. Ποῖον οἶκον οἰκοδομήσετέ μοι, ἢ τίς τόπος τῆς καταπαύσεώς μου; Καταλείπω δὲ ὑμῖν, ἐπ᾿ αὐτῶν τῶν βιβλίων γενομένοις, ἀκριβέστερον τὰς ἐκείνων ἐξετάσαι προφητείας, ὅπως μετὰ τοῦ προσήκοντος λογισμοῦ τὴν καθ᾿ ἡμᾶς ἐπήρειαν ἀποσκευάσησθε.
