In his first years as patriarch of Constantinople, Eutychius called together the [[Fifth Ecumenical Council]], in which [[heresy|heresies]] were [[anathema]]tized. He had much more trouble battling the heresy of [[Aphthartodocetism]], the belief that [[Jesus Christ]] was imperishable and was not able to suffer while dying on the Cross, since Emperor Justinian was allegedly fooled by the teaching. The emperor grew angry with Eutychius and sent him into exile to an Amasean monastery in the year 565.
While living the [[
askesis|ascetic]] life in exile, he continued to serve the Lord diligently and worked miraculous bodily healings and spiritual cleansings. The saint ensured that stored grain was never used up by praying to the Lord after Persians invaded and brought Amasea to ruins. Saint Eutychius also was granted the gift of prophecy, predicting the successors of Emperor Justinian.
After remaining in exile for twelve years, Eutychios returned to his rightful position in 577. On [[April 6]], 582, he called his clergy together as he reposed in peace.
