He became Pope in 649, at the time of the Monothelite heresy. In order to establish peace in the Church, Emperor Constans II wrote the heretical booklet "Tipos". Pope Martin convened a council of 105 bishops, at which he condemned the emperor's booklet. The emperor sent Duke Olympos to bring the pope to him. Olympos sent a soldier to behead him in the church, but when he entered the church, he was blinded and the duke was killed by the Saracens. The emperor, persuaded by the heretic Patriarch Paul, sent another duke, Theodore, who brought the bound Pope Martin to Constantinople. There the pope lay in prison for a long time, until he was exiled to Cherson, where, in 655, he reposed in the Lord. Two years before him, Patriarch Paul died, who wept bitterly before the emperor for his sin against Pope Martin.
