Hierarch
Hierarch Eustathius, Bishop of Antioch
ок. 270 — ок. 337 (в изгнании)
Hierarch Eustathius, Bishop of Antioch — the presiding defender of Nicene orthodoxy against Arianism at the First Ecumenical Council of Nicaea (325), deposed on a false Arian-instigated charge and who died a natural death in exile in Thrace.
St. Eustathius of Antioch was Bishop of Beroea and then Archbishop of Antioch from 325, a leading Church Father and the presiding bishop at the First Ecumenical Council of Nicaea, where he vigorously opposed Arius.
His staunch Nicene orthodoxy made him enemies among Arian-leaning bishops, who deposed him around 330 on trumped-up charges (accounts differ between Sabellianism and immorality) and had him exiled to Thrace by Emperor Constantine. Although his accuser later publicly retracted the charge, he was never restored and died a natural death in exile, never returning to his see.
His relics were translated to Antioch in 482. He is remembered as a major exegete of the Antiochene school, opposing Origen's allegorical method; only his treatise On the Belly-Myther (against Origen) survives complete.
His feast is kept on February 21/March 6.
IMPORTANT CORRECTION: category martyr→hierarch — pravenc.ru itself titles him "hierarch" and explicitly states he "died his own [natural] death" in exile, rather than being executed.
