The Holy Canons Chalcedon Canon 20
Canon 20 A cleric may not move to another city's church
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
Clerics who belong to a church, as we have already decreed, are not permitted to be appointed to the church of another city, but are to be content with that in which they were from the beginning counted worthy to minister; except those who, having lost their own native lands by necessity, have passed over to another church. And if any bishop, after this decree, should receive a cleric belonging to another bishop, it has seemed good that both the one received and the one who received him be out of communion, until the cleric who has moved away returns to his own church.
Κληρικοὺς εἰς ἐκκλησίαν τελοῦντας, καθὼς ἤδη ὡρίσαμεν, μὴ ἐξεῖναι εἰς ἄλλης πόλεως τάττεσθαι ἐκκλησίαν· ἀλλὰ στέργειν ἐκείνην, ἐν ᾗ λειτουργεῖν ἐξ ἀρχῆς ἠξιώθησαν, ἐκτὸς ἐκείνων, οἵτινες ἀπολέσαντες τὰς οἰκείας πατρίδας ἀπὸ ἀνάγκης, εἰς ἄλλην ἐκκλησίαν μετῆλθον. Εἰ δέ τις ἐπίσκοπος μετὰ τὸν ὅρον τοῦτον, ἄλλῳ ἐπισκόπῳ προσήκοντα δέξοιτο κληρικόν, ἔδοξεν ἀκοινώνητον εἶναι καὶ τὸν δεχθέντα, καὶ τὸν δεξάμενον, ἕως ἂν ὁ μεταστὰς κληρικὸς εἰς τὴν ἰδίαν ἐπανέλθῃ ἐκκλησίαν.
