Pope Martin I of Rome.
St. Martin the Confessor was Pope of Rome in the seventh century. He convened a council at the Lateran which condemned the Monothelite heresy, defending the fullness of Christ's humanity against the will of the emperor. For this he was seized by imperial soldiers, carried off to Constantinople, tried and mistreated, and exiled to Cherson on the Black Sea.
Worn down by hunger and hardship, he died in exile, a confessor for the Orthodox faith honored by East and West alike. He is commemorated on April 13.
