Canon 6
About the invalidity of the so-called “absolute” ordinations (without belonging to a temple).
It is decided not to ordain anyone without appointment - neither a presbyter, nor a deacon, nor in general anyone belonging to the church rank - unless each person being ordained is assigned to the church of a city, or a temple dedicated to a martyr, or a monastery. Regarding those ordained without an exact appointment, the Holy Council determined: their ordination should be recognized as invalid and nowhere should they be allowed to serve, to the shame of the one who ordained them.
Greek original
Μηδένα ἀπολελυμένως χειροτονεῖσθαι, μήτε πρεσβύτερον, μήτε διάκονον, μήτε ὅλως τινὰ τῶν ἐν τῷ ἐκκλησιαστικῷ τάγματι· εἰ μὴ εἰδικῶς ἐν ἐκκλησίᾳ πόλεως, ἢ κώμης, ἢ μαρτυρίῳ, ἢ μοναστηρίῳ, ὁ χειροτονούμενος ἐπικηρύττοιτο. Τοὺς δὲ ἀπολύτως χειροτονουμένους, ὥρισεν ἡ ἁγία σύνοδος, ἄκυρον ἔχειν τὴν τοιαύτην χειροθεσίαν, καὶ μηδαμοῦ δύνασθαι ἐνεργεῖν, ἐφ᾿ ὕβρει τοῦ χειροτονήσαντος.
