On the immutability of the Creed and the anathema of the heresies of the Eunomians, Arians, Sabellians, etc. (6 in total)
The Holy Fathers, gathered in Constantinople, determined: let the faith of the 318 fathers gathered in Nicaea of Bithynia not be rejected, but let it remain immutable, and let all heresy be anathematized, namely: the heresy of the Eunomians, or Eudoxians, Semi-Arians, or Doukhobors, Sabellians, Marcellians, Photinians and Apollinarians.
Greek original
Ὥρισαν οἱ ἐν Κωνσταντινούπολει συνελθόντες ἅγιοι Πατέρες, μὴ ἀθετεῖσθαι τὴν πίστιν τῶν Πατέρων τῶν τριακοσίων δέκα ὀκτώ, τῶν ἐν Νικαίᾳ τῆς Βιθυνίας συνελθόντων· ἀλλὰ μένειν ἐκείνην κυρίαν, καὶ ἀναθεματισθῆναι πᾶσαν αἵρεσιν· καὶ εἰδικῶς τὴν τῶν Εὐνομιανῶν, εἴτ᾿ οὖν Εὐδοξιανῶν, καὶ τὴν τῶν Ἡμιαρείων, εἴτ᾿ οὖν Πνευματομάχων, καὶ τὴν τῶν Σαβελλιανῶν, καὶ τὴν τῶν Μαρκελλιανῶν, καὶ τὴν τῶν Φωτεινιανῶν, καὶ τὴν τῶν Ἀπολλιναριστῶν.
