It is celebrated on May 5 each year.
Saint Euthymios was born in Epivates of Thrace at the beginning of the 10th century AD. His sister in the flesh was Osia Paraskevi the Passenger (celebrated on October 14). When Nikitas’ father died, his mother took him to a monastery in Constantinople, where he remained for thirty years and excelled in spiritual struggles. But the Saint loved the quiet. For this reason he left the monastery and practiced in a deserted area as a hermit.
His theophilic life made him a steward of God’s mysteries. He was ordained a deacon by the then Bishop of Perinthos, and then an Elder by another Bishop. Finally, he was appointed Bishop of Madytos of the Hellespont, distinguished for his unceasing practice of virtue and his excellent pastoral ability. God gave him the gift of miracles and during his life he performed many miracles and healed lepers and deaf mutes.
The fame of the Holy man reached the palace and the emperor Basil II (976 – 1025 AD), who visited Agios Euthymios in Maditos. There the Saint prophesied the victory of the king against Varda Phokas in 989 AD.
Saint Euthymius slept in peace between the years 989 – 996 AD. During his final repose, myrrh flowed from his tomb, as proof of the sanctity of his life, and many sick people were healed. That is why he was called Myroblytis.
After his righteous death, he was glorified by God to perform miracles. Which we know from the eulogy to him by George of Cyprus, later Patriarch of Constantinople, which he wrote at the request of Athens Meletius, who was then presiding over the Church of Madytos and Koili.
