Fount and Light

Ὅτι παρὰ σοὶ πηγὴ ζωῆς ἐν τῷ φωτί σου ὀψόμεθα φῶς. Ἐπεὶ παρὰ σοὶ πηγὴ ζωῆς, αὑτη δέ ἐστιν ὁ εἰπὼν ̓Εγώ εἰμι ὁ ὤν, εἰκότως καὶ τὸν χειμάρρουν τῆς τρυφῆς σου ἐρχόμενον ἀπὸ τῆς πηγῆς τῆς ζωῆς ποτιεῖς τοὺς μεθυσθέντας ἀπὸ πιότητος τοῦ οἰκου σου. Πηγὴ δὲ ζωῆς ὁ σωτὴρ τῷ μὴ ἐξωθεν ἔχειν ἀλλὰ παρέχειν αὐτὸν ἀπασι τοῖς ζῶσιν, οὐκ ἀνθρώποις μόνοις ἀλλὰ καὶ τοῖς ὑπεραναβεβηκόσι κατὰ τὰ αὐτὰ θείαν ζωήν, καθὸ καὶ πηγὴ σοφίας λέγεται· χείμαρρος δὲ τρυφῆς τὸ ἅγιον πνεῦμα τῷ τρυφᾶν τοὺς πεπωκότας ἀπ' αὐτοῦ δεχομένους τὰ διάφορα αὐτοῦ χαρίσματα. ̓ Εν τῷ φωτί σου ὀψόμεθα φῶς·  Φῶς τοῦ θεοῦ τὸ ἀληθινὸν φῶς, τὸ  Απαύγασμα τοῦ φωτὸς τοῦ ἀιδίου. Ἐν τούτῳ οὖν τῷ φωτὶ ὀψόμεθα φῶς, σὲ τὸ ἀίδιον φῶς περὶ ου εἴρηται ̔Ο θεὸς φῶς ἐστιν. συμβαλεῖς τούτῳ ̔Ο ἐμὲ ἑωρακὼς ἑώρακε τὸν πατέρα. Δίδυμος Αλεξανδρεύς, Εἰς Ψαλμους, Ψαλμος ΛΕ'

For with you is the fount of life and in your light we see light. 1   Since with you is the fount of life, and this is He who says 'I am He  who is,' 2 and perhaps drinking from the delights pouring forth from the fount of life we shall be intoxicated by the richness of your house. 3 The fount of life is the Saviour, He who needs nothing from outside, but He supplies every living thing, not only men, but even things above, and so He is named the fount of wisdom. And the pouring forth of delights is the Holy Spirit, because those who have drunk  from Him receive various graces.   'In your light we see light.'   That is, the true light of God, the splendor of the eternal light. It is in this light that we see light, You, the eternal light, concerning whom it is said, 'God is light,' 4 and again, 'He who sees me, sees the Father.' 5 Didymus the Blind, Commentary on the Psalms, from Psalm 35 1 Ps 35.10 2 Ex 3.14 3 Ps 35.9 4 1 Jn 1.5 5 Jn 14.9
