st.Mark

Mark was born Emmanuel in 1392 in Constantinople to George, Chief Justice of the Sakellion and Orthodox deacon, and Maria, the daughter of a devout doctor named Luke. Mark learned how to read and write from his father, who died while Mark and his younger brother John were still children. Maria had Mark continue his education under John Cartasmeno, who later became Metropolitan Ignatius of Selmyria, and a mathematician and philosopher by the name of George Gemistos Plethon
He died peacefully at the age of 52 on June 23, 1444, after an excruciating two week battle with intestinal illness. On his death bed, Mark implored Georgios Scholarios, his former pupil, who later became Patriarch Gennadius of Constantinople, to be careful of the snares of the West and to defend Orthodoxy. According to his brother John, his last words were "Jesus Christ, Son of the Living God, into Thy hands I commit my spirit." Mark was buried in the Mangana Monastery in Constantinople.
The Eugenikos family celebrated each anniversary of Mark’s death with a eulogy consisting of a service (akolouthia) and synaxarion of a short life of Mark. Thanks in large part to Patriarch Gennadius Scholarius, veneration of Mark spread among the Church. In 1734 Patriarch Seraphim of Constantinople presided over the Holy Synod of the Church of Constantinople and solemnly canonized Mark and added six services to the two older ones.
There is an account of a posthumous miracle performed by St. Mark of Ephesus. Doctors gave up on trying to save the life of the terminally ill sister of Demetrios Zourbaios, after their efforts had worsened her condition. After losing consciousness for three days she suddenly woke up to the delight of her brother, who asked her why she woke up drenched in water. She related that a bishop escorted her to a fountain and washed her and told her, "Return now; you no longer have any illness." She asked him who he was and he informed her, "I am the Metropolitan of Ephesus, Mark Eugenikos." After being miraculously healed, she made an icon of St. Mark and lived devoutly for another 15 years.
