A Warning About Inferior Studies

Οὐ καλῶς τὰς Ἀθήνας θαυμάζεις, καὶ Στοὰν, καὶ Περίπατον, καὶ Ἀττικὴν φαντασίαν, οἶς διὰ μάθησιν φλυαρίας πάλαι προσεκαρτέρεις, ὁ τὰ γήῖνα περιφρονήσας, καὶ μηδὲν ἀγαπᾷν τῶν ἐνταῦθα κεκελευσμένος. Εἰ συνηγέρθης οὖν τῷ Χριστῷ, τὰ ἄνω φρόνει, οὐ ἐστιν αὐτός. Οἰ γὰρ τὴν εὐτελῆ ἐσθῆτὰ σου ὁρῶντες, καὶ φιλοσοφίαν ἐν μόνῳ σχήματὶ προσοῦσαν, περπερείαν δὲ γνώμης, καὶ γλώσσης ἀλαζονείαν, κατὰ τῆς θειοτάτης θρησκείας βλασφημοῦσι.  Ἅγιος Ἰσίδωρος Του Πηλουσιώτου, Βιβλίον Πρῶτον, Ἐπιστολή ΣΚΖ', Φλωρεντιῳ Source: Migne PG 78. 324d

You do not do well to admire Athens, and the Stoa and the Peripatetics and Attic pomp, worthless studies in which you were once so attentive, contemplating things of the earth, nothing of which here you have been commanded to love. 1 If, then, you have risen with Christ, think on things above, where He is. 2 For they seeing your tawdry garb and pursuit of philosophy in solitary state, with vainglorious mind and boastful tongue will blaspheme against the most Divine religion.  Saint Isidore of Pelusium, Book 1, Letter 227, to Florentius 1 1 Jn 2.15 2 Colos 3.2
