Book 1, Chapter 20

ὅπως δὲ ἀπεστάλθαι ἑαυτὸν καὶ ἡγιάσθαι πρὸ τοῦ ἀποσταλῆναι ὑπὸ τοῦ πατρὸς ἐδίδασκεν, καὶ ὡς τοὺς ὀκνοῦντας υἱὸν αὐτὸν ὁμολογεῖν τοῦ θεοῦ δυσωπεῖ διδάσκων ἐκ τῆς θείας γραφῆς ὡς οὐ μόνον υἱοὶ θεοῦ ἀλλὰ καὶ θεοὶ θνητοὶ τὴν φύσιν ἄνδρες ἐκλήθησαν· διὸ μὴ χρῆναι νομίζειν βλάσφημον εἶναι τὸ καὶ υἱὸν θεοῦ καὶ θεὸν ὁμολογεῖν »ὃν ὁ πατὴρ ἡγίασεν καὶ ἀπέστειλεν εἰς τὸν κόσμον«.
