The persecution within is worse than the persecution without
Clement is explaining Jesus' saying about receiving fields, money, houses, and brothers 'with persecutions' in this present time, and he distinguishes outward persecution from the inward persecution of the soul by its own passions.
The passage that follows holds to the same judgment. "Now in this present time," Jesus says, "to have fields and money and houses and brothers with persecutions—to what end?" For he does not call people to life without money, without a home, without brothers. He has called rich people too, but in the way we have already described, and brothers in the same way—like Peter with Andrew, and James with John, the sons of Zebedee—but brothers who agree with one another and with Christ. What he rejects is having each of these things "with persecutions." One kind of persecution comes from outside, from people who drive out the faithful through hatred or envy or greed or the working of the devil. But the harshest persecution is from within, sent out from each person's own soul when it is ravaged by godless desires and varied pleasures and base hopes and corrupting dream-fancies—when the soul, always reaching for more and raging with savage loves and burning, is goaded by the passions that cling to it as by stings or a gadfly toward mad pursuits and despair of life and contempt for God. This persecution is heavier and harsher, springing from within, always present, and the one persecuted cannot escape it; for he carries the enemy around inside himself everywhere. So too a burning that falls from outside produces testing, but a burning from within brings about death. And a war brought from outside is easily ended, but the war in the soul is measured out until death. If with such a persecution you have visible wealth, or brothers by blood, or the other pledges, abandon the total possession of these things that leads to evil; give yourself peace; free yourself from a long persecution; turn away from those things to the gospel; choose the Savior before all things, the advocate and defender of your soul, the ruler of boundless life. "For the things that are seen are temporary, but the things that are not seen are eternal" (2 Corinthians 4:18); and in the present time they are short-lived and unstable.

Ταύτης δὲ ὁμοίως ἔχεται τῆς γνώμης καὶ τὸ ἑπόμενον. »νῦν δὲ ἐν τῷ καιρῷ τούτῳ ἀγροὺς καὶ χρήματα καὶ οἰκίας καὶ ἀδελφοὺς ἔχειν μετὰ διωγμῶν εἰς ποῦ;« οὔτε γὰρ ἀχρημάτους οὔτε ἀνεστίους οὔτε ἀναδέλφους ἐπὶ τὴν ζωὴν καλεῖ. ἐπεὶ καὶ πλουσίους κέκληκεν, ἀλλ᾿ ὃν τρόπον προειρήκαμεν, καὶ ἀδελφοὺς κατὰ ταὐτὸν ὥσπερ Πέτρον μετὰ Ἀνδρέου καὶ Ἰάκωβον μετὰ Ἰωάννου, τοὺς Ζεβεδαίου παῖδας, ἀλλ᾿ ὁμονοοῦντας ἀλλήλοις τε καὶ Χριστῷ. τὸ δὲ »μετὰ διωγμῶν« ταῦτα ἕκαστα ἔχειν ἀποδοκιμάζει· διωγμὸς δὲ ὃ μέν τις ἔξωθεν περιγίνεται τῶν ἀνθρώπων ἢ δι᾿ ἔχθραν ἢ διὰ φθόνον ἢ διὰ φιλοκέρδειαν ἢ κατ᾿ ἐνέργειαν διαβολικὴν τοὺς πιστοὺς ἐλαυνόντων· ὁ δὲ χαλεπώτατος ἔνδοθέν ἐστι διωγμός, ἐξ αὐτῆς ἑκάστῳ τῆς ψυχῆς προπεμπόμενος λυμαινομένης ὑπὸ ἐπιθυμιῶν ἀθέων καὶ ἡδονῶν ποικίλων καὶ φαύλων ἐλπίδων καὶ φθαρτικῶν ὀνειροπολημάτων, ὅταν. ἀεὶ τῶν πλειόνων ὀρεγομένη καὶ λυσσῶσα ὑπὸ ἀγρίων ἐρώτων καὶ φλεγομένη, καθάπερ κέντροις ἢ μύωψι τοῖς προσκειμένοις αὐτῇ πάθεσιν ἐξαιμάσσηται πρὸς σπουδὰς μανιώδεις καὶ ζωῆς ἀπόγνωσιν καὶ θεοῦ καταφρόνησιν. οὗτος ὁ διωγμὸς βαρύτερος καὶ χαλεπώτερος, ἔνδοθεν ὁρμώμενος, ἀεὶ συνών, ὃν οὐδὲ ἐκφυγεῖν ὁ διωκόμενος δύναται· τὸν γὰρ ἐχθρὸν ἐν ἑαυτῷ περιάγει πανταχοῦ. οὕτω καὶ πύρωσις ἡ μὲν ἔξωθεν προσπίπτουσα δοκιμασίαν κατεργάζεται, ἡ δὲ ἔνδοθεν θάνατον διαπράσσεται. καὶ πόλεμος ὁ μὲν ἐπακτὸς ῥᾳδίως καταλύεται, ὁ δὲ ἐν τῇ ψυχῇ μέχρι θανάτου παραμετρεῖται. μετὰ διωγμοῦ τοιούτου πλοῦτον ἐὰν ἔχῃς τὸν αἰσθητὸν κἂν ἀδελφοὺς τοὺς πρὸς αἵματος καὶ τὰ ἄλλα ἐνέχυρα, κατάλιπε τὴν τούτων παγκτησίαν τὴν ἐπὶ κακῷ, εἰρήνην σεαυτῷ παράσχες, ἐλευθερώθητι διωγμοῦ μακροῦ, ἀποστράφηθι πρὸς τὸ εὐαγγέλιον ἀπ᾿ ἐκείνων, ἑλοῦ τὸν σωτῆρα πρὸ πάντων, τὸν τῆς σῆς συνήγορον καὶ παράκλητον ψυχῆς, τὸν τῆς ἀπείρου πρύτανιν ζωῆς. »τὰ γὰρ βλεπόμενα πρόσκαιρα, τὰ δὲ μὴ βλεπόμενα αἰώνια·« καὶ ἐν μὲν τῷ παρόντι χρόνῳ ὠκύμορα καὶ ἀβέβαια.
