Ignatius to Polycarp

Let not those that seem to be plausible and yet teach strange doctrine dismay thee. Stand thou firm, as an anvil when it is smitten. It is the part of a great athlete to receive blows and be victorious. But especially must we for God's sake endure all things, that He also may endure us.

Οἱ δοκοῦντες ἀξιόπιστοι εἶναι καὶ ἑτεροδιδασκαλοῦντες μή σε καταπλησσέτωσαν. στῆθι ἑδραῖος ὡς ἄκμων τυπτόμενος. μεγάλου ἐστιν ἀθλητοῦ τὸ δέρεσθαι καὶ νικᾶν. μάλιστα δὲ ἕνεκεν θεοῦ πάντα ὑπομένειν ἡμᾶς δεῖ, ἵνα καὶ αὐτὸς ἡμᾶς ὑπομείνῃ.
