Hell And Destruction

Ἡ Γραφή φησίν· Ἄδης καὶ ἀπώλεια φανερὰ παρὰ Κυρίῳ. Ταυτα δε περὶ καρδιακῆς ἀγνοίας και λήθης λέγει. Ἄδης ἐστὶν ἄγνοια· ἀπώλεια δὲ ἐστι λήθη. Ἀμφότερα δέ ἐστιν ἀφάνερα· διότι ἐξ ὑπαρχόντων ἀπώλοντο. Ἅγιος Μάρκος ὁ Ἐρημίτης, Περὶ Νόμου Πνευματικοῦ  Source: Migne PG 65 913a

Scripture says, 'Hell and destruction are manifest to the Lord.' 1 And these things are said of ignorance of the heart and forgetfulness. Hell is ignorance and destruction is forgetfulness. And both are unseen, whence comes ruin. Saint Mark The Ascetic, On The Spiritual Law. 1 Prov 15.11
