Canon I
The Faith of the Three Hundred and Eighteen Fathers assembled at Nice in Bithynia shall not be set aside, but shall remain firm. And every heresy shall be anathematized, particularly that of the Eunomians or [Anomæans, the Arians or] Eudoxians, and that of the Semi-Arians or Pneumatomachi, and that of the Sabellians, and that of the Marcellians, and that of the Photinians, and that of the Apollinarians.
