Peter Thomas proved to be a brilliant diplomat, all the while committed to an austere, simple and prayerful life of a Carmelite friar. He was known to have a disarming humility that enabled him to converse with peasants, soldiers and sailors just as easily as high government officials. After being made Bishop of Patti and Lipari in 1354, he was entrusted with many papal missions to promote peace and unity with the Eastern Churches. He held positions of Papal Legate for the East, Archbishop of Crete and Latin Patriarch of Constantinople, all the while working for peace and unity between churches of East and West. His work ended in 1366 when he died of a fever at Famagosta on Cyprus, where his body was then buried in the Carmelite church there.

  St Peter Thomas lived as a devout Carmelite and was a diplomatic healer and reconciler, reminding us that finding common ground and bringing reconciliation are always possible with God’s help.

  In 428, Nestorius, the new Patriarch of Constantinople (and hence one of the most important bishops in the world) made statements that could be interpreted as denying the divinity of Christ. The dual nature – human and divine – has always been hard for us to accept or understand, and if it seems easy it is only because we have not thought about it properly. Those who dislike problems have had two responses: to deny the human nature of Christ or to deny his divinity: and either leads to disaster, since both deny the Incarnation and hence the divinisation of human nature.

  Cyril fought strongly against the teachings of Nestorius and took the lead at the Council of Ephesus, plunging into the turbulent politics of the time and defending the Catholic faith through to its ultimate victory.

  Cyril wrote many works to explain and defend the Catholic faith. He died in 444.

  In the earliest centuries all vestments were white – the white of baptismal purity and of the robes worn by the armies of the redeemed in the Apocalypse, washed white in the blood of the Lamb. As the Church grew secure enough to be able to plan her liturgy, she began to use colour so that our sense of sight could deepen our experience of the mysteries of salvation, just as incense recruits our sense of smell and music that of hearing. Over the centuries various schemes of colour for feasts and seasons were worked out, and it is only as late as the 19th century that they were harmonized into their present form.
