Saint Eutychius, Archbishop of Constantinople, was born in a village called Divinoe in the Phrygian region. His father, Alexander, was a soldier, and his mother, Synesia, was the daughter of the priest of the Augustopolsky Hesychius church. Saint Eutychius received his primary education and Christian upbringing from his grandfather, a priest. One day, during a child's play, the boy wrote his name with the title of patriarch and this seemed to indicate his future ministry. At the age of 12, he was sent to Constantinople to receive further education. The young man excelled in the study of sciences and realized that human wisdom is nothing compared to the teachings of Divine Revelation. 
He decided to devote himself to the monastic life. Saint Eutychius retired to one of the Amasian monasteries and accepted the Angelic rank there. During his strict life, he was appointed archimandrite of all the Amasian monasteries, and in 552 he was elevated to the patriarchal throne.
When the Fifth Ecumenical Council was being prepared under the holy King Justinian (527-565), Metropolitan Amasia was ill and sent Saint Eutychius in his place. In Constantinople, the aged patriarch Saint Mina (536-552, August 25) saw Blessed Eutychius and predicted that he would be patriarch after him. After the death of the holy Patriarch Mina, the Apostle Peter appeared in a vision to the Emperor Justinian and, pointing to Eutychius, said: "May he be appointed to you by the bishop."
At the beginning of the patriarchal ministry of Saint Eutyches, the Fifth Ecumenical Council (553) was convened, at which the fathers condemned the heresies that had arisen and anathematized them. However, a few years later, a new heresy arose in the Church, the author of the Orthodoxers, that is, the "incorruptible ones," who taught that the flesh of Christ was incorruptible and did not suffer before the death on the Cross and Resurrection.
Saint Eutychius boldly exposed this heresy, but Emperor Justinian, who himself was inclined to it, unleashed his wrath on the saint. By order of the emperor, the soldiers seized the saint in the temple, tore off his patriarchal vestments and sent him into exile to the Amasi monastery (in 565).
The saint meekly endured exile, remained in the monastery in fasting and prayer, and performed many miracles and healings.
So, through his prayer, the wife of a pious Androgynous husband, who had previously given birth only to dead babies, had two sons born and reached adulthood. Two deaf-mute youths were given the gift of speech; two children, who were seriously ill, recovered. The saint healed the cancer on the artist's arm. The saint healed another artist by anointing his sore hand with oil and making the sign of the cross over it. The saint healed not only bodily but also mental illnesses: he exorcised a demon from a young woman who did not allow her to receive Holy Communion.; He exorcised a demon from a young man who had run away from a monastery (after that, the young man returned to his monastery); he healed a drunkard leper who, having been cleansed of leprosy, stopped drinking.
During the Persian attack on Amazia and the general devastation of the inhabitants, on the instructions of the saint, grain was given to the hungry from the monastery granaries, and the grain supplies in the monastery did not run out due to his prayers.
Saint Eutychius received the gift of prophecy from God; thus, he indicated the names of two emperors who succeeded Justinian - Justin (565-578) and Tiberius (578-582).
After the death of the holy Patriarch John Scholastic, Saint Eutychius returned to the pulpit in 577 from a 12-year exile and once again began to wisely manage his flock.
Four and a half years after his return to the patriarchal throne, Saint Eutyches gathered the entire clergy on Sunday of St. Thomas in 582, gave a blessing, and departed in peace to the Lord.
