'''Arius''' was a [[heretic]] of the early fourth century who taught that the Son of God was not eternal, that the Son was a created being, and was subordinate to God the Father. This belief was considered a [[heresy]], called [[Arianism]]. that was condemned by the Ecumenical Council at [[Nicea]] in 325. Yet, the controversy over the heresy continued after the Council as [[Arius]] returned to the favor of the Emperor. Only the unusual death of Arius, followed a year later by the death of Constantine, temporarily overshadowed the controversy.
