Speaking And Doing

Σοφιστεύεις ὄντως, καὶ γράφων, καὶ κάλλη πλαττεις ὀνομάτων. Χρὴ δὲ καὶ ἀφορμὰς παρέχειν ἐν αὐτοῖς ὠφελείας πραγμάτων. Τὸ γὰρ καλῶς λέγειν κυμβάλῳ παρέοικε. Τὸ δὲ χρηστῶς πράττειν ἀγγέλιος συμπέφυκεν. Οἶς καὶ ἔμφοβος καὶ ἀμελλητος ὑπακοὴ τὸ ποιεῖν τὰ θελήματα τοῦ Θεοῦ μαρτυρεῖ. Ἅγιος Ἰσίδωρος Του Πηλουσιώτου, Βιβλίον Πρῶτον, Ἐπιστολὴ ΡΞΓ' Κυρῳ Source: Migne PG 78.292a

You are a fine orator and write and arrange words most beautifully. But it is necessary for you to attend to the profitable substance of deeds. For to speak finely is to be like a cymbal, 1 whereas to act well is of the nature of angels. Their awe and prompt obedience to the will of God bears witness to this. Saint Isidore of Pelusium, Book 1, Letter 163, To Cyrus 1 1 Cor 13.1
