Understanding and the Animal Man

Tὸ γὰρ πνεῦμα πάντα ἐραυνᾷ, καὶ τὰ βάθη τοῦ θεοῦ. Βάθη τοῦ Θεοῦ τῶν ἱερῶν Γραμμάτων ἡ κεκρυμμένη καὶ ἀπόθετος γνῶσις, ἢς εἰδὸς τὸ Πνεῦμα ταῖς τῶν ἁγίων ἀποκαλύπτει ψυχαῖς, θεῖον τινα νοῦν ἀποφεῖνον τὸν αὐτοῖς. Ψυχινὸς δὲ ἄνθρωπος οὐ δέχεται τὰ τοῦ πνεύματος τοῦ θεοῦ, μωρία γὰρ αὐτῷ ἐστιν, καὶ οὐ δύναται γνῶναι... Ψυχινός ἐστιν ὁ κατὰ σάρκα ζῶν καὶ μήπω τὸν νοῦν φωτισθεὶς διὰ τοῦ Πνεύματος, ἀλλὰ μόνην τὴν ἐμφυτον καὶ ἀνθρωπίνην σύνεσιν ἔχων, ἤν ταῖς ἀπὰντων ψυχαῖς ἐμβάλλει ὁ Δημιουργός. Ἅγιος Κύριλλος Ἀλεξανδρείας, Εἰς Τὴν Πρωτάν Ἐπιστολήν Παύλου Πρὸς Κορινθίους, Ἐκλογαι Source: Migne PG 74.865b-c

For the Spirit scrutinises everything, even the depths of God... The depths of God are the secret and hidden meanings of Holy Scripture, which the Spirit reveals to those who have holy souls, making a certain Divine mind dwell in them. But the animal man does not receive the things of the Spirit of God, because it is foolishness to him, and he cannot understand... 1 An animal because of his living according to the flesh and not yet having a mind enlightened by the Holy Spirit, but only having the innate human understanding, which is sent into every soul by the Creator. Saint Cyril of Alexandria, Commentary on the First Letter to the Corinthians, Fragment 1 1 Cor 2.14
