: ...ὥστε τοὺς τῆς Ποντικῆς καὶ τῆς Ἀσιανῆς καὶ τῆς Θραικικῆς διοικήσεως μητροπολίτας μόνους, ἔτι δὲ καὶ τοὺς ἐν τοῖς βαρβαρικοῖς ἐπισκόπους τῶν προειρημένων διοικήσεων χειροτονεῖσθαι ὑπὸ τοῦ προειρημένου ἁγιωτάτου θρόνου τῆς κατὰ Κωνσταντινούπολιν ἁγιωτάτης ἐκκλησίας... (translation) The three regions mentioned in this canon-Pontus, Asia, and Thrace-were all dioceses within the Roman empire. This canon makes no explicit provision for Constantinople's jurisdiction over territories not already in the empire. In fact, note μόνους, which suggests that Constantinople ought not have authority beyond these three regions.
