Our Father Among the Saints '''Mark of Ephesus''' (Evgenikos), Pillar of Orthodoxy, was famous for his courageous defense of Orthodoxy at the [[Council of Florence]] (1439 A.D.) in spite of the [[John VIII Palaeologus|emperor]] and the [[Eugenius IV of Rome|pope of Rome]]. He held Rome to be heretical in [[schism]] and [[heresy]] for its acceptance of the [[Filioque|''Filioque '' clause]] added to the [[Nicene-COnstantinopolitan Constantinopolitan Creed]] and for the claims of the [[papacy]] to universal jurisdiction over the [[Church]], and was thus the only Eastern [[bishop ]] to refuse to sign the decrees of the council.

He died peacefully in the year [[1452]] A.D. On his death bed, Mark implored Gregory, his disciple, and later Patriarch [[Gennadius II (Scholarius ) of Constantinople|Gennadius]], to be careful of the snares of the West and to defend Orthodoxy.
