"ST. CONSTANTINE, King and Martyr, was a British prince, said to have been King of Cornwall. He resigned his crown, and was ordained priest. Constantine is reported to have arrived in Scotland at the same time as St. Columba, to have founded a monastery at Govan, to have preached to the Scots and Picts, and to have converted the district of Cantyre to the Faith. He ended his course by martyrdom. (It appears to be doubtful whether he was or was not the same Constantine of Cornwall, against whose enormous crimes St. Gildas so loudly inveighs.)."[25]
His feast day is observed on March 9 in the tradition of Cornwall and Wales; and on March 11 in the Scottish and Irish traditions. Two places in Cornwall are still named after him today.
Troparion of St Constantine Tone 5
Grieving at the loss of thy young spouse,/ thou didst renounce the world, O Martyr Constantine,/ but seeing thy humility God called thee to leave thy solitude and serve Him as a priest./ Following thy example,/ we pray for grace to see that we must serve God as He wills/ and not as we desire,/ that we may be found worthy of His great mercy. Kontakion of St Constantine Tone 4
Thou wast born to be King of Cornwall,/ O Martyr Constantine,/ and who could have foreseen that thou wouldst become the first hieromartyr of Scotland./ As we sing thy praises, O Saint,/ we acknowledge the folly of preferring human plans to the will of our God.[19]
