Words And Deeds

Καλὰ μὲν πάνη λεγεῖς, κακὰ δὲ λίαν πράττεις· ἐν γὰρ δὴ σχήμασι καὶ ῥήμασι τῆς καλοκαγαθίας ἐξαπατῶν τοὺς κούφους, καὶ κρύπτων τὴν σαυτοῦ σκαιότητα, κατάφορος εὑρίσκῃ τοῖς εὐφρονοῦσιν, οὐκ ἐξ ὦν λέγεις καὶ πλάττῃ, ἀλλ' ἐξ ὦν ἐργάζῃ, ῥᾳδίως καταλαμβανόντων σε.  Ἅγιος Νειλος, Βιβλιον Πρῶτον, Ἐπιστολὴ ϟΕ' Βαβυλᾳ Διακονῳ Source: Migne PG 79 124c

You speak very well but act exceedingly wickedly, for in the forms and words of an upright fellow you deceive the simple, concealing your crookedness, which you may find will be swept away among those with good minds, who not by the deceitful things you say but by your deeds will easily understand you. Saint Nilus of Sinai, Book 1, Letter 95, To Babyla The Deacon
