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 glorified (canonized) Mark and added six services to the two older ones. There is an account of a posthumous miracle performed by 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 Saint Mark and lived devoutly for another 15 years.

Nikodimos of the Holy Mountain, in his service to the saint, called him "the Atlas of Orthodoxy." His feast day is January 19, the day his relics were moved to the monastery of Lazarus in Galata.

In addition to canons and services to Jesus Christ, the Mother of God, and the angels, Mark honored his favorite Fathers of the Church: Gregory Palamas, John Damascene, Symeon Metaphrastes, along with a wealth of more ancient saints. Additionally, Mark composed verses celebrating the lives and achievements of his heroes, such as Joseph Bryennios. Hesychasm Mark was a devoted disciple of Gregory Palamas. Throughout his life he composed several treatises in defense of the essence-energies distinction, and he defended the unique contributions of Hesychast theology in the face of charges of innovation. Dogmatic/polemical theology One of Mark's most important theological contributions was his opposition to the Roman Catholic Filioque. At the Council of Florence, the examination of this controversy had both text-critical and exegetical dimensions,
