Aerius of Sebaste
Aerius of Pontus (also Aërius, Aëris) was a 4th-century presbyter of Sebaste in Pontus. He taught doctrines that were in opposition to the Roman Catholic Church's beliefs. His views are known from St Epiphanius's Panarion in which he was accused of being an Arian. For a short period, he had many followers in Sebaste. He failed to make his teachings widely popular and his sect died out soon after his death.
Life and teachings
Aerius was a priest and a friend and fellow ascetic of Eustathius of Sebaste. Eustathius became bishop of Sebaste in the year 355 and would later ordain Aerius and put him in charge of the hospital in Sebaste. Aerius fell out with Eustathius, due to the bishop having deserted ascetic practices. Aerius soon began to teach new doctrines, insisting that there was no sacred character distinguishing bishop or priest from laymen, that the observance of the feast of Easter was a Jewish superstition, and that it was wrong to prescribe fasts or abstinences by law, and useless to pray for the dead. His followers, known as Aerians, fasted on Sundays and would not do so on the appointed fast-days, even during Holy Week.
