Bishop Euthymius was one of those assembled at the Seventh Ecumenical Council in Nicaea in 787; it was he who formulated the Council’s official declaration on veneration of the holy icons. During the reign of Nicephorus I (802-811),Euthymius’ enemies made false accusations against him that led to his being deposed and exiled for several years. He was called back to Constantinople by the iconoclast Emperor Leo the Armenian (813-820), who sought his support in attacking the icons; but Euthymius refused, and was exiled once more. On Leo’s death, he was summoned before another iconoclast Emperor, Michael II (820-829), who in turn asked the Saint’s support in his blasphemous campaign against the icons. The holy bishop not only refused, but cried out ‘Let anyone who does not worship Our Lord Jesus Christ represented in image according to His humanity, be anathema!’ The enraged Emperor exiled him again (his third exile), imprisoning him in a foul dungeon at the far east of the Black Sea for three years. He was then summoned to appear before his third Emperor in succession, the iconoclast Theophilus (829-42). For holding firm in the Faith once delivered to the saints, the holy bishop was mercilessly flogged with rods, then with the sinews of oxen until his body swelled up ‘like a wineskin.’ He was then thrown into a dungeon where, after eight days in terrible pain, he gave up his soul to God.
The Saint’s precious relics worked many miracles, and were venerated in Constantinople until the City’s fall in 1453, when they were taken to Cherson in the Crimea, then to Chilea near Chalcedon. When most of the Greeks were expelled from Asia Minor in 1922, the people of Chilea brought the Saint’s skull to Greece, where a church was built in his honor in Pireus; the holy relic may be venerated there today.
