I’m not Catholic, but I can tell you for a fact that there is no St Arius. You’re probably thinking of St Athanasiua, who was one of Arius’ theological opponents.
That should read “St Athanasius.” Stupid smartphone keyboard.
Is the Arian Catholic Church a false sect of the Catholic Church?
Arius was recognized as a Saint and Martyr by the Arian Catholic Church on 16th June 2006, which has become his memorial day.
St Arius - Founder of Arianism
Presbyter Saint Arius - remembered for his views
concerning the trinity and
the divinity of
Christ
Arius Officially NOT a Heretic! An interesting point to note is that because Arius was officially re-instated into the Full Communion of the church before he died in 336 AD, by the Emperor of Rome, Constantine I, he officially is NOT excommunicated and therefore NOT a heretic according to the Roman Catholic church!
