Canon 10 A cleric may not be enrolled in two cities

Κανόνες τῆς ἐν Χαλκηδόνι Ἁγίας καὶ Οἰκουμενικῆς Δ´ Συνόδου

The Fourth Ecumenical Council · Chalcedon, 451 · convened by the emperor Marcian · Fourth Ecumenical Council: Chalcedon (451) on the map

It is not lawful for a cleric to be enrolled at the same time in the churches of two cities, both in that in which he was ordained at the first and in that to which he has fled, as to a supposedly greater one, out of desire for empty glory. And those who do this are to be restored to their own church, in which they were ordained from the beginning, and to minister there only. If, however, anyone has already been transferred from one church to another, he is to have no part in the affairs of the former church, or of the martyrs' shrines, or poorhouses, or hostels under it. And as for those who dare, after the decree of this great and ecumenical council, to do any of the things now forbidden, the holy synod has decreed that they fall from their own rank.

Μὴ ἐξεῖναι κληρικὸν ἐν δύο πόλεων κατὰ ταὐτὸν καταλέγεσθαι ἐκκλησίαις, ἐν ᾗ τε τὴν ἀρχὴν ἐχειροτονήθη, καὶ ἐν ᾗ προσέφυγεν, ὡς μείζονι δῆθεν, διὰ δόξης κενῆς ἐπιθυμίαν. Τοὺς δέ γε τοῦτο ποιοῦντας ἀποκαθίστασθαι τῇ ἰδίᾳ ἐκκλησίᾳ, ἐν ᾗ ἐξ ἀρχῆς ἐχειροτονήθησαν, καὶ ἐκεῖ μόνον λειτουργεῖν. Εἰ μέν τοι ἤδη τις μετετέθη ἐξ ἄλλης εἰς ἄλλην ἐκκλησίαν, μηδὲν τοῖς τῆς προτέρας ἐκκλησίας, ἤτοι τῶν ὑπ᾿ αὐτὴν μαρτυρίων, ἢ πτωχείων, ἢ ξενοδοχείων ἐπικοινωνεῖν πράγμασι. Τοὺς δέ γε τολμῶντας, μετὰ τὸν ὅρον τῆς μεγάλης καὶ οἰκουμενικῆς ταύτης συνόδου, πράττειν τι τῶν νῦν ἀπηγορευμένων, ὥρισεν ἡ ἁγία σύνοδος ἐκπίπτειν τοῦ ἰδίου βαθμοῦ.
