Ignatius — Epistle to the Magnesians 7
As therefore the Lord did nothing without the Father, being united to Him, neither by Himself nor by the apostles, so neither do anything without the bishop and presbyters. Neither endeavour that anything appear reasonable and proper to yourselves apart; but being come together into the same place, let there be one prayer, one supplication, one mind, one hope, in love and in joy undefiled. There is one Jesus Christ, than whom nothing is more excellent.
Therefore run together as into one temple of God, as to one altar, as to one Jesus Christ, who came forth from one Father, and is with and has gone to one.

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.
