Anomoeanism

In 4th century Christianity, the Anomoeans, also spelled "Anomeans" and known also as Heterousians, Aëtians, or Eunomians, were a sect that upheld an extreme form of Arianism, which denied not only that Jesus Christ was of the same nature (consubstantial) as God the Father but even that he was of like nature (homoiousian), as maintained by the semi-Arians.
