Although the members of the Orthodox delegation signed the Tomos of Union, Saint Mark was the only one who refused to do so. When he returned from Florence, Saint Mark urged the inhabitants of Constantinople to repudiate the dishonorable document of union. He died in 1457 at the age of fifty-two, admired and honored by all.
Troparion — Tone 4
By your profession of faith, O all-praised Mark / The Church has found you to be a zealot for truth. / You fought for the teaching of the Fathers; / You cast down the darkness of boastful pride. / Intercede with Christ God to grant forgiveness to those who honor you!
Kontakion — Tone 3
Clothed with invincible armor, O blessed one, / You cast down rebellious pride, / You served as the instrument of the Comforter, / and shone forth as the champion of Orthodoxy. / Therefore we cry to you: “Rejoice, Mark, the boast of the Orthodox!”
