Ignatius — Epistle to the Magnesians 4
It is fitting, then, not only to be called Christians, but to be so in reality: as some indeed give one the title of bishop, but do all things without him. Now such persons seem to me to be not possessed of a good conscience, seeing they are not stedfastly gathered together according to the commandment.
Greek
Πρέπον οὖν ἐστιν μὴ μόνον καλεῖσθαι Χρις τιανούς, ἀλλὰ καὶ εἶναι: ὥσπερ καί τινες ἐπίσκοπον μὲν καλοῦσιν, χωρὶς δὲ αὐτοῦ πάντα πράσσουσιν. οἱ τοιοῦτοι δὲ οὐκ εὐσυνείδητοί μοι εἶναι φαίνονται διὰ τὸ μὴ βεβαίως κατ’ ἐντολὴν συναθροίζεσθαι.
