Saint Martin I, Pope and Martyr
Saint Martin I, Pope and Martyr, was a 7th-century pontiff who defended the Church against heresy and suffered martyrdom for his faith.

Defender of the Faith
Saint Martin I served as Pope from 649 to 653, a period marked by theological disputes within the Church. He is best known for his staunch opposition to Monothelitism, a heresy claiming that Christ had only one will. To address this, Martin convened the Lateran Council of 649, which condemned Monothelitism and the Typos, an edict by Emperor Constans II that forbade discussion of Christ's wills. This courageous stand led to his arrest and eventual martyrdom.
In 653, Emperor Constans II ordered Martin's arrest. After enduring public humiliation and torture in Constantinople, Martin was exiled to Cherson in Crimea, where he died on September 16, 655. His unwavering commitment to the truth and his suffering for the faith have made him a revered figure in both the Roman Catholic and Eastern Orthodox Churches.
A Martyr for Orthodoxy
Born near Todi, Umbria, Italy, Martin was known for his intelligence, piety, and charity. Before becoming pope, he served as the papal legate to Constantinople, where he witnessed the spread of Monothelitism. His election as pope in 649 was marked by immediate action against this heresy, culminating in the Lateran Council of 649.
Martin's steadfast defense of orthodox doctrine led to his arrest by Emperor Constans II in 653. After enduring severe torture and exile, he died in 655. His martyrdom underscores the cost of fidelity to the truth and the Church's teachings.
Thou didst adorn the divine see of Peter, and since from this divine Rock, thou didst immovably defend the Church, so now thou art glorified with him.
— Byzantine BreviaryBlessed are those who are persecuted for righteousness' sake, for theirs is the kingdom of heaven.
