Ignatius — Epistle to the Magnesians 7
The Lord was one with the Father and did nothing without him (John 5:19): nothing on his own, nothing through the apostles. In the same way, you must do nothing without the bishop and the presbyters. Do not try to make some private course look reasonable to yourselves. Come together in one place: one prayer, one plea, one mind, one hope, in love, in spotless joy. That joy is Jesus Christ, and nothing is better than he.
Run together, all of you, as to one temple of God, as to one altar, to one Jesus Christ. He came forth from one Father; he is with that One; and to that One he has returned.
Greek
Ὥσπερ οὖν ὁ κύριος ἄνευ τοῦ πατρὸς οὐδὲν ἐποίησεν, ἡνωμένος ὤν, οὔτε δἰ ἑαυτοῦ οὔτε διὰ τῶν ἀποστόλων: οὕτως μηδὲ ὑμεῖς ἄνευ τοῦ ἐπισκόπου καὶ τῶν πρεσβυτέρων μηδὲν πράσσετε: μηδὲ πειράσητε εὔλογόν τι φαίνεσθαι ἰδίᾳ ὑμῖν, ἀλλ’ ἐπὶ τὸ αὐτὸ μία προσευχή, μία δέησις, εἷς νοῦς, μία ἐλπὶς ἐν ἀγάπῃ, ἐν τῇ χαρᾷ τῇ ἀμώμῳ, ὅ ἐστιν Ἰησοῦς Χριστός, οὖ ἄμεινον οὐδέν ἐστιν.
πάντες ὡς εἰς ἕνα ναὸν συντρέχετε θεοῦ, ὡς ἐπὶ ἓν θυσιαστήριον, ἐπὶ ἕνα Ἰησοῦν Χριστόν, τὸν ἀφ̓ ἑνὸς πατρὸς προελθόντα καὶ εἰς ἕνα ὄντα καὶ χωρήσαντα.
