Theophilus of Antioch, To Autolycus 9
God's people, as bearers of the Holy Spirit and having become prophets, were inspired and made wise by God Himself, and so became God-taught, holy, and righteous. For this reason they were deemed worthy to receive this reward, having become instruments of God and having received wisdom from Him; through that wisdom they spoke about the creation of the world and everything else. They also foretold plagues, famines, and wars. Not merely one or two, but many were raised up at various times and seasons—not only among the Hebrews but also among the Greeks, a Sibyl—and all have spoken in friendly accord with one another, covering both the events before them, those in their own day, and those now being fulfilled among us. Therefore we too are convinced that the things to come will be so, just as the first things were fulfilled.
Greek
Οἱ δὲ τοῦ θεοῦ ἄνθρωποι, πνευματοφόροι πνεύματος ἁγίου καὶ προφῆται γενόμενοι, ὑπ᾿ αὐτοῦ τοῦ θεοῦ ἐμπνευσθέντες καὶ σοφισθέντες, ἐγένοντο θεοδίδακτοι καὶ ὅσιοι καὶ δίκαιοι. Διὸ καὶ κατηξιώθησαν τὴν ἀντιμισθίαν ταύτην λαβεῖν, ὄργανα θεοῦ γενόμενοι καὶ χωρήσαντες σοφίαν τὴν παρ᾿ αὐτοῦ, δι᾿ ἧς σοφίας εἶπον καὶ τὰ περὶ τῆς κτίσεως τοῦ κόσμου καὶ τῶν λοιπῶν ἁπάντων. Καὶ γὰρ περὶ λοιμῶν καὶ λιμῶν καὶ πολέμων προεῖπον. Καὶ οὐχ εἷς ἢ δύο ἀλλὰ πλείονες κατὰ χρόνους καὶ καιροὺς ἐγενήθησαν παρὰ Ἑβραίοις, ἀλλὰ καὶ παρὰ Ἕλλησιν Σίβυλλα· καὶ πάντες φίλα ἀλλήλοις καὶ σύμφωνα εἰρήκασιν, τά τε πρὸ αὐτῶν γεγενημένα καὶ τὰ κατ᾿ αὐτοὺς γεγονότα καὶ τὰ καθ᾿ ἡμᾶς νυνὶ τελειούμενα· διὸ καὶ πεπείσμεθα καὶ περὶ τῶν μελλόντων οὕτως ἔσεσθαι, καθὼς καὶ τὰ πρῶτα ἀπήρτισται.
