ARIANISM
Arianism
Arianism is the theological teaching attributed to Arius, a Christian presbyter in Alexandria, Egypt, concerning the relationship of God the Father to the Son of God, Jesus Christ. Arius asserted that the Son of God was a subordinate entity to God the Father. Deemed a heretic by the Ecumenical First Council of Nicaea of 325, Arius was later exonerated in 335 at the regional First Synod of Tyre, and then, after his death, pronounced a heretic again at the Ecumenical First Council of Constantinople of 381. The Roman Emperors Constantius II and Valens were Arians or Semi-Arians.The above text is a snippet from Wikipedia: Arianism
