Descent And Darkness

Καὶ ἔκλινεν οὐρανὸν καὶ κατέβη καὶ γνόφος ὑπὸ τοὺς πόδας αὐτοῦ. Ἡ δὲ κατάβασις, τῇ τοῦ Σωτῆρος ἀκόλουθος οἰκονομίᾳ· κατέβη δὲ οὐ τοπικῶς, ἀλλὰ τῷ ἐν μορφῇ Θεοῦ ὑπάρχων, μορφὴν δούλου λαβεῖν, τὸ δὲ ἀσαφὲς καὶ λανθάνον τῆς τοῠ Θεοῦ γνῶσεως, διὰ τοῦ γνόφου παρίσταται· εἰς τοῦτο γὰρ καὶ Μωῦσῆς, ὡς ἦν ἀνθρώπῳ δυνατὸν, εἰσελήλυθεν· τοιαύτη καὶ ἡ δεῦρο ἐπιδημία τῷ μὴ δι' ὅλων ἐγνῶσθαι τοῖς γενητοῖς. Δυδύμος του Ἀλεξανδρέως, Εἰς Ψαλμους, Ψαλμος ΙΖ' Source: Migne PG 39.1244-45

And He bent heaven and came down and darkness was beneath his feet. 1 This descent is consonant with the incarnation of the Lord, for He did not descend in space, but when in the form of God to take up the form of a slave. 2 And that which is obscure and hidden is the knowledge of God, which through darkness appears, into which Moses penetrated, as much as it is possible for a man. And this signifies the dwelling here of the Lord, known to none but a few. Didymus the Blind, Commentary on the Psalms, from Psalm 17 1 Ps 17.10 2 Philip 2.6-7
