Ignatius to the Magnesians

Therefore let us not be insensible to His goodness. For if He should imitate us according to our deeds, we are lost. For this cause, seeing that we are become His disciples, let us learn to live as beseemeth Christianity. For whoso is called by another name besides this, is not of God.

Μὴ οὖν ἀναισθητῶμεν τῆς χρηστότητος αὐτοῦ. ἐὰν γὰρ ἡμᾶς μιμήσηται καθὰ πράσσομεν, οὐκέτι ἐσμέν. διὰ τοῦτο, μαθηταὶ αὐτοῦ γενόμενοι, μάθωμεν κατὰ Χριστιανισμὸν ζῆν. ὃς γὰρ ἄλλῳ ὀνόματι καλεῖται πλέον τούτου, οὐκ ἔστιν τοῦ θεοῦ.
