Speakers Of Vanities

Τοὺς ἐγγαστριμύθους, καὶ τοὺς ἀπὸ τῆς γῆς φωνοῦντας, τοὺς κενολογοῦντας, καθώς φησιν ἡ Γραφὴ φευκτέον ἡμῖν· πᾶς γὰρ κεκωλυμένος, καὶ ψευδὴς λόγος, κενός ἐστιν ἀληθείας. Βλέπε, τί φασιν ἐν τῷ Εὐαγγελίῳ, ὅτι Ἐκ τοῦ πληρώματος τοῦ Θεοῦ ἐλάβομεν. Οἱ δέ γε κενολογοῦντες αἱρετικοὶ οὐκ ἔχουσι λόγους ἐκ πληρώματος, πάντας δὲ κενοὺς τῆς ἀληθείας, καὶ κενοὺς τῆς θείας δυνάμεως, καὶ σοφίας. Οἴτινες ἐκ τῆς κοιλίας φωνοῦσιν· οἱ γὰρ μὴ ἔχοντες μὲν τὴν ἀλήθειαν ἐπαγγελλόμενοι δὲ ταύτην, δῆλον ὅτι ἐκ κοιλίας φωνοῦσι, τῇ ἑαυτῶν κοιλίᾳ δουλεύοντες, ὧν Θεὸς ἡ κοιλία λελόγισται. Ἡ γὰρ πηγὴ τῶν λόγων τῶν γαστριμάργων οὐκ ἐξ ἁγίου προέρχεται Πνεύματος, οὐκ ἀπὸ ἡγεμονικοῦ, οὐκ ἀπὸ τῆς καρδίας τῆς τὸν Χριστὸν ποθούσης, ἀλλ' ἀπὸ κοιλίας ἐκβλύζεται.

They who speak from their stomachs and they who cry out from the earth, are the speakers of vanities, and as it says in Scripture, 'Flee them,' 1 for every forbidden and lying word is empty of truth. See what it says in the Gospel: 'From the fullness of God we have received.' 2 He who has the vain words of heretics does not have the words of fulness but is empty of every truth and Divine power and wisdom. They who cry out from their stomachs are they who do not possess the truth but what they declare is clear in the yelping of their bellies, for they are slaves of the same, as it is said, 'Their God is their stomach.' 3 For the fount of the words of those who speak from their stomachs does not proceed forth from the Holy Spirit, nor from the highest part of a man, nor from the heart desiring Christ, but they belch forth from their lower parts. Saint Nilus of Sinai, Book 1, Letter 256 To Pelagius 1 Lev 19.31 2 Jn 1.16 3 Phillip 3.19
