“ξύλα καὶ χόρτος καὶ καλάμη ὥστε μηκέτι ὑπάρχειν—ἀδύνατον δέ ἐστιν οὕτως ἀφανισθῆναι, ἀλλὰ ᾗ χόρτος εἰσὶν ἀφανίζονται· καὶ γὰρ τὸ πῦρ τοῦτο τὸ τῆς κολάσεως οὐκ ἐνεργεῖ εἰς οὐσίαν, ἀλλ᾽ εἰς ἕξεις καὶ ποιότητας. ἀναλίσκει τὸ πῦρ τοῦτο οὐ κτίσματα, ἀλλὰ ποιὰς καταστάσεις, ἕξεις τοιάσδε.

It is impossible that wood, grass, and straw disappear in such a way as to not exist any more, but they [viz., sinners] will disappear insofar as they are grass and so on. Indeed, this fire of the corrective punishment is not active against the substance, but against the habits and qualities. For this fire consumes, not creatures, but certain conditions and certain habits. (Didymus, Comm. In Ps. 20-21 col. 21.15)”
