The man of half-grown intelligence, when he observes an object which is bathed in the glow of a seeming beauty, thinks that that object is in its ess… - Gregory of Nyssa

Just as, in the case of the sunlight, on one who has never from the day of his birth seen it, all efforts at translating it into words are quite thrown away; you cannot make the splendour of the ray shine through his ears; in like manner, to see the beauty of the true and intellectual light, each man has need of eyes of his own; and he who by a gift of Divine inspiration can see it retains his ecstasy unexpressed in the depths of his consciousness; while he who sees it not cannot be made to know even the greatness of his loss. How should he? This good escapes his perception, and it cannot be represented to him; it is unspeakable, and cannot be delineated. We have not learned the peculiar language expressive of this beauty. … What words could be invented to show the greatness of this loss to him who suffers it? Well does the great David seem to me to express the impossibility of doing this. He has been lifted by the power of the Spirit out of himself, and sees in a blessed state of ecstacy the boundless and incomprehensible Beauty; he sees it as fully as a mortal can see who has quitted his fleshly envelopments and entered, by the mere power of thought, upon the contemplation of the spiritual and intellectual world, and in his longing to speak a word worthy of the spectacle he bursts forth with that cry, which all re-echo, "Every man a liar!" I take that to mean that any man who entrusts to language the task of presenting the ineffable Light is really and truly a liar; not because of any hatred on his part of the truth, but because of the feebleness of his instrument for expressing the thing thought of.

ὥστε εἰ μὲν ὠφελοίη τι καὶ ἡ λέξις ὡς εἴρηται νοουμένη, ἔχειν ἐξ ἑτοίμου τὸ σπουδαζόμενον, εἰ δέ τι μετὰ ἐπικρύψεως ἐν ὑπονοίαις τισὶ καὶ αἰνίγμασιν εἰρημένον ἀργὸν εἰς ὠφέλειαν εἴη κατὰ τὸ πρόχειρον νόημα, τοὺς τοιούτους λόγους ἀναστρέφειν.

If we truly think of Christ as our source of holiness, we shall refrain from anything wicked or impure in thought or act and thus show ourselves to be worthy bearers of his name. For the quality of holiness is shown not by what we say but by what we do in life.
