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 also that he was of like nature (homoiousian), as maintained by the semi-Arians. In the 5th century, the Anomoean presbyter Philostorgius wrote an Anomoean Church history.
