St Theodore was a Byzantine Greek from Tarsus in Cilicia. He went to Rome where he became a monk in a Greek monastery. He was made Archbishop of Canterbury in 668. He called a synod at Hertford to re-order the church. He set up a school of learning which enabled him to send out monks who would be trained in the monastic life. A synod inn 680 at Hatfield affirmed the third council of Constantinople with regard to the two wills, human and divine, in the person of Christ.
