Παρασκευασώμεθα τοίνυν πρὸς εὐποιίαν, πρὸς δικαιοσύνην, ἵνα ἡ νηστεία λάβῃ πτερά. Ὥσπερ γὰρ πετεινόν, ἐὰν μὴ ἔχῃ τὴν τῶν πτερύγων συνέργειαν, ἵπτασθαι οὐ δύναται, οὕτως καὶ ἡ νηστεία δύο πτερὰ ἔχει, προσευχὴν καὶ ἐλεημοσύνην, ὧν ἄνευ ἄνω τρέχειν οὐ δύναται. Βλέπε τὸν Κορνήλιον μετὰ τῆς νηστείας καὶ ταῦτα τὰ πτερὰ κεκτημένον. Διὸ καὶ φωνῆς αὐτῷ γενομένης ἤκουσεν οὐρανόθεν· Κορνήλιε, αἱ προσευχαί σου καὶ αἱ ἐλεημοσύναι σου ἀνέβησαν πρὸς τὸν θεόν. Ὑπόθου ζῷον εἶναι τὴν νηστείαν, ἀγαπητέ. Πτερὰ δὲ πάλιν ταύτης ἐλεημοσύνην καὶ προσευχὴν καθεστάναι, ὧν ἄνευ ταύτην ἄνω μὴ δύνασθαι τρέχειν. Ὁ τοιοῦτος, κἂν μὴ λαλῇ, γλώττῃ μεγάλῃ τὸ δίκαιον βοᾷ. Μεγάλη γὰρ δικαιοσύνης συνήγορος ἀρετή. Διὸ λέγει· Εἰσάκουσον, κύριε, δικαιοσύνης μου. Πρῶτον μὲν οὖν καὶ μέγιστον ἀγαθὸν προσευχὴ καὶ ἐλεημοσύνη καὶ δικαιοπραγία, τὸ δὲ ἀσφαλὲς καὶ ἀσάλευτον καὶ ῥίζα πάντων ἡ περὶ τὸν θεὸν γνῶσις, ἡ τοῦ μονογενοῦς προσκύνησις, ἡ τοῦ ἁγίου πνεύματος ὁμολογία, μία πίστις, ἀδιαίρετος, ἀσφαλής, ἄσχιστος, ἀμέριστος. Εἴρηται, ὃ μέλλω λέγειν, ἀλλ’ ὅμως πάλιν λέγω. Ὁ θεὸς σοφὸς ὢν συνεχώρησεν ἀπὸ τῶν ἰδίων ἐξάρχων τὰς αἱρέσεις ἔχειν τὰς ἐπωνυμίας τῶν ἰδίων δογμάτων, ἵνα φανῇ, ὅτι οὐ θεοῦ δόγμα, ἀλλ’ ἀνθρώπων ἐστὶν εὕρεμα τὰ παρ’ αὐτῶν δοξαζόμενα· οἷον, Μακεδονιανοὶ ἀπὸ Μακεδονίου, Ἀρειανοὶ ἀπὸ Ἀρείου, Εὐνομιανοὶ ἀπὸ Εὐνομίου· ὁμοίως καὶ αἱ λοιπαὶ αἱρέσεις. Τὴν μέντοι πίστιν τῶν ἀποστόλων ἄτρωτον θέλων φυλάξαι οὐ συνεχώρησεν αὐτοῖς ἀπὸ ἀνθρώπου ὀνομάζεσθαι.

Let us therefore prepare ourselves for beneficence, for righteousness, so that fasting may take wings. For just as a bird, if it does not have the cooperation of its wings, cannot fly, so also fasting has two wings, prayer and almsgiving, without which it cannot run upward. Observe Cornelius, who possessed fasting together with these wings. Hence, when a voice came to him from heaven, he heard: "Cornelius, your prayers and your alms have ascended to God." Suppose, beloved, that fasting is a living creature. And again, that its wings are almsgiving and prayer, without which it cannot run upward. Such a person, even if he does not speak, proclaims righteousness with a great tongue. For virtue is a great advocate of righteousness. Hence it says: "Hearken, O Lord, to my righteousness." First and greatest good, then, is prayer and almsgiving and righteous action, but the secure and unshakable foundation and root of all is knowledge concerning God, the worship of the Only-Begotten, the confession of the Holy Spirit, one faith, undivided, secure, unrent, unparted. It has been said, what I am about to say, but nevertheless I say it again. God, being wise, permitted the heresies to have their appellations from their own founders, from their own doctrines, so that it might be manifest that what is glorified by them is not a doctrine of God but a human invention: for example, Macedonians from Macedonius, Arians from Arius, Eunomians from Eunomius; and similarly the remaining heresies. The faith of the apostles, however, wishing to keep it invulnerable, he did not permit to be named after any human being.
