Ignatius — Epistle to the Philadelphians 6
But if any one preach the Jewish law unto you, listen not to him. For it is better to hearken to Christian doctrine from a man who has been circumcised, than to Judaism from one uncircumcised. But if either of such persons do not speak concerning Jesus Christ, they are in my judgment but as monuments and sepulchres of the dead, upon which are written only the names of men.
Flee therefore the wicked devices and snares of the prince of this world, lest at any time being conquered by his artifices, grow weak in your love. But be all joined together with an undivided heart. And I thank my God that I have a good conscience in respect to you, and that no one has it in his power to boast, either privately or publicly, that I have burdened any one either in much or in little.
And I wish for all among whom I have spoken, that they may not possess that for a testimony against them.
Greek
Ἐὰν δέ τις ἰουδαϊσμὸν ἑρμηνεύῃ ὑμῖν, μὴ ἀκούετε αὐτοῦ. ἄμεινον γάρ ἐστιν παρὰ ἀνδρὸς περιτομὴν ἔχοντος χριστιανισμὸν ἀκούειν, ἢ παρὰ ἀκροβύστου ἰουδαῖσμόν. ἐὰν δὲ ἀμφότεροι περὶ Ἰησοῦ Χριστοῦ μὴ λαλῶσιν, οὗτοι ἐμοὶ στῆλαί εἰσιν καὶ τάφοι νεκρῶν, ἐφ̓ οἷς γέγραπται μόνον ὀνόματα ἀνθρώπων. φεύγετε οὖν τὰς κακοτεχνίας καὶ ἐνέδρας τοῦ ἄρχοντος τοῦ αἰῶνος τούτου, μήποτε θλιβέντες τῇ γνώμῃ αὐτοῦ ἐξασθενήσετε ἐν τῇ ἀγάπῃ: ἀλλὰ πάντες ἐπὶ τὸ αὐτὸ γίνεσθε ἐν ἀμερίστῳ καρδίᾳ. εὐχαριστῶ δὲ τῷ θεῷ μου, ὅτι εὐσυνείδητός εἰμι ἐν ὑμῖν καὶ οὐκ ἔχει τις καυχήσασθαι οὔτε λάθρα οὔτε φανερῶς, ὅτι ἐβάρησά τινα ἐν μικρῷ ἢ ἐν μεγάλῳ. καὶ πᾶσι δέ, ἐν οἷς ἐλάλησα, εὔχομαι, ἵνα μὴ εἰς μαρτύριον αὐτὸ κτήσωνται.
