Clement of Rome, 1 Clement 47
Take up the letter of the blessed apostle Paul and consider what he wrote to you at the very beginning of the gospel. He truly wrote to you under the Spirit's guidance about himself, Cephas, and Apollos, because even then you had formed factions. But that division brought you a lesser sin, since you were aligning yourselves with apostles who had been testified to and with a man approved by them. Now consider who has led you astray and diminished the noble character of your renowned brotherly love. It is shameful, beloved, utterly shameful, and unworthy of the conduct that belongs to life in Christ, that the most established and ancient church of the Corinthians should be in rebellion against its presbyters because of one or two persons. This report has reached not only us, but also those who differ from us, so that blasphemies are heaped on the Lord's name because of your folly, and you are bringing danger upon yourselves.

Ἀναλάβετε τὴν ἐπιστολὴν τοῦ μακαρίου Παύλου τοῦ ἀποστόλου. τί πρῶτον ὑμῖν ἐν ἀρχῇ τοῦ εὐαγγελίου ἔγραψεν ; ἐπ’ ἀληθείας πνευματικῶς ἐπέστειλεν ὑμῖν περὶ ἑαυτοῦ τε καὶ Κηφᾶ τε καὶ Ἀπολλώ, διὰ τὸ καὶ τότε προσκλίσεις ὑμᾶς πεποιῆσθαι. ἀλλ’ ἡ πρόσκλισις ἐκείνη ἥττονα ἁμαρτίαν ὑμῖν προσήνεγκεν: προσεκλίθητε γὰρ ἀποστόλοις μεμαρτυρημένοις καὶ ἀνδρὶ δεδοκιμασμένῳ παῤ αὐτοῖς. νυνὶ δὲ κατανοήσατε, τίνες ὑμᾶς διέστρεψαν καὶ τὸ σεμνὸν τῆς περιβοήτου φιλαδελφίας ὑμῶν ἐμείωσαν. αἰσχρά, ἀγαπητοί, καὶ λίαν αἰσχρά, καὶ ἀνάξια τῆς ἐν Χριστῷ ἀγωγῆς ἀκούεσθαι, τὴν βεβαιοτάτην καὶ ἀρχαίαν Κορινθίων ἐκκλησίαν δἰ ἓν ἢ δύο πρόσωπα στασιάζειν πρὸς τοὺς πρεσβυτέρους: καὶ αὕτη ἡ ἀκοὴ οὐ μόνον εἰς ἡμᾶς ἐχώρησεν, ἀλλὰ καὶ εἰς τοὺς ἑτεροκλινεῖς ὑπάρχοντας ἀφ̓ ἡμῶν, ὥστε καὶ βλασφημίας ἐπιφέρεσθαι τῷ ὀνόματι κυρίου διὰ τὴν ὑμετέραν ἀφροσύνην, ἑαυτοῖς δὲ κίνδυνον ἐπεξεργάζεσθαι.
