The Shadow Of Death And True Death

Ἐὰν γὰρ καὶ πορευθῶ ἐν μέσῳ σκιᾶς θανάτου...  Νοοῖτο δ' ἂν σκιὰ θανάτου καὶ ὁ φυσικὸς καὶ κοινὸς θάνατος, πρὸς ἀντιδιαστολὴν τοῦ προαιρετικοῦ θανάτου, τοῦ τῆς ψυχῆς, φημὶ, ὂς οὐκ ἔστι σκιὰ θανάτου, ἀλλὰ θάνατος ἀληθής. Ἅγιος Κύριλλος Ἀλεξανδρείας, Εἰς Τους Ψαλμους, Ψαλμός ΚΒ' Source: Migne PG 69.841b

'For if I walk in the shadow of death...' 1   One may think that the shadow of death is the physical and common death, to distinguish it from the death that is by choice, I mean, of the soul, which is not the shadow of death but true death. Saint Cyril of Alexandria, Commentary on the Psalms, from Psalm 22 1 Ps 22.4
