Knowledge and Night

Καὶ τὴν ἀλήθειάν σου κατὰ νύκτα Θεολογίας καὶ θεοπτείας ὑπόθεσις τυγχάνων, τέλος ἔχει τὴν ἀλήθειαν, ἢν ἀναγγέλλειν προσήκει, οὐκ ἐξ ἐπιπολῆς καὶ ἐκ τῶν φανερῶν πραγμάτων, ἀλλ' ἐκ βαθέων καὶ ἀποκρύφων, διαγνώσεως ὑπερβολήν. Τὴν δὲ σοφίαν τὴν ἐν τοῖς τοιούτοις ὠνόμασιν νυκτα· φύσει γὰρ τὰ περὶ Θεοῦ εὐσεβῶς και ὀρθῶς λεγόμενα, τῆς τῶν πολλῶν γνώσεως, διὰ μέγεθος δυνάμεως, ἀποδημεϊ. Νὺξ δὲ ἐστι διὰ τὸ δυσκατάληπτον· αὕτη δὲ νὺξ ἀναφορὰν ἔχει πρὸς τὸ σκότος, ὅ ἔθετο ὁ Θεὸς ἀποκρυφὴν αὐτοῦ. Δίδυμος Αλεξανδρεύς, Εἰς Ψαλμους, Ψαλμος ϞΑ'

And Your Truth through the night. 1    The true end of theology and Divine vision is not to attain to the announcement of obvious and manifest things but that which is deep and hidden, for that is highest knowledge. And the knowledge of such things is called night, for naturally when such things are spoken of God piously and rightly it escapes many minds, on account of the greatness of their power. Night, then, it is called because it is difficult to grasp. Night is when the darkness is brought forth, in which God places his hiding place. 2 Didymus the Blind, Commentary on the Psalms, Psalm 91 1 Ps 91.3 2 Ps 17.12
