Guarding Against Vainglory

Εἰ δὲ ὑπὸ τῆς κενοδοξίας καὶ τοῦ τῶν ἀνθρώπων ἐπαίνου δεινῶς τυραννῇ, ὀφείλεις μηδὲν πρὸς ἐπίδειξιν τῶν ἀνθρώπων ποιεῖν, ἀλλὰ πᾶσαν τὴν ἐργασίαν σου ποιεῖν ἐν κρυπτῷ, μηδενὸς ἄλλου εἰδότος, ἢ του Θεοῦ μόνου· καὶ μὴ ἀγάπα τοὺς ἐπαίνους, μηδὲ τὰς τιμὰς τῶν ἀνθρώπων, μηδὲ τὰ καλὰ ἱμάτια, μηδὲ τὴν προτίμησιν, καὶ τὴν πρωτοκαθεδρίαν· μάλλον δὲ ἀγάπα ἵνα σε ψέγωσιν οἱ ἄνθρωποι, καὶ κατηγορῶσι καὶ ἀτιμάζωσι ψευδόμενοι· καὶ ἔχε ἑαυτὸν παντὸς ἁμαρτωλοῦ ἁμαρτωλότερον. Άγιος Ιωάννης ο Δαμασκηνός, Περι Των Ὀκτώ Τῆς Πονηρίας Πνευμάτων Source: Migne PG 95 82c-d

If glorying in vanities and the praises of men rules heavily over you, never should you do anything before men, but let all the works that you do be done in secret, known to no one but God alone; 1 and guarding against love of the praises and honours of men, refuse fine vestments, first portions and first seats, but rather love that men insult you, and accuse and dishonour you by their lies, and hold yourself as the most sinful of sinners. Saint John of Damascus, On The Eight Wicked Spirits 1 cf Mt 6.1-6
