Ignatius to the Trallians

Be ye therefore on your guard against such men. And this will surely be, if ye be not puffed up and if ye be inseparable from [God] Jesus Christ and from the bishop and from the ordinances of the Apostles.

Φυλάττεσθε οὖν τοὺς τοιούτους. τοῦτο δὲ ἔσται ὑμῖν μὴ φυσιουμένοις καὶ οὖσιν ἀχωρίστοις θεοῦ Ἰησοῦ Χριστοῦ καὶ τοῦ ἐπισκόπου καὶ τῶν διαταγμάτων τῶν ἀποστόλων.

He that is within the sanctuary is clean; but he that is without the sanctuary is not clean, that is, he that doeth aught without the bishop and presbytery and deacons, this man is not clean in his conscience.
