Martin was born at Todi in Umbria. He became a member of the clergy of Rome and was elected pope in 649. He convened the council which condemned the heresy of the Monothelites, which denied that Christ had two wills. In 653 he was taken prisoner by the Emperor Constans II and detained in Constantinople where he was forced to suffer many indignities. Finally, having been exiled to Crimea, he died in 655. He is venerated as a martyr. – CTS New Daily Roman MIssal 2012, p 2635; Christian Prayer 1990, p 1116.
