He is famous not only for the beauty of expression of his homilies but also for his hymns, which have spread far beyond his native Syriac church and are in use in East and West alike.

  Brazil at this time was in a very bad way spiritually. On the one hand, there were the Indians to be evangelized and led away from pagan practices including cannibalism (to which they were much attached). On the other hand, both the European settlers and many of the priests, finding themselves in a land where there was no real authority, lived scandalous lives, practising both slavery and concubinage. When the Jesuits arrived in Brazil in 1549 they worked hard to regularize the situation.

  Brother Anchieta became the assistant and interpreter of the Jesuit superior Father Nóbrega. They set up a mission which later grew into the city of São Paulo, and Anchieta made the school there his headquarters. He learned the local Tupi language and wrote the first ever grammar of it; he wrote dramas to teach the faith to the illiterate and the uneducated; he gave medical assistance to the Indians and taught them skills such as agriculture, carpentry, and the use of stone and metal. With Nóbrega he gave himself up as a hostage in 1563 so that a peace settlement could be reached between two warring tribes, and he narrowly escaped martyrdom on more than one occasion.

  He was ordained a priest in 1566 and was the Jesuit Provincial in Brazil from 1577 to 1587. He died on 9 June 1597, exhausted by his labours.

  He was beatified by Pope John Paul II in 1980 and recognized as a saint by Pope Francis on April 2014.

  He studied in Paris and in Cologne under the great philosopher St Albert the Great, at a time of great philosophical ferment, when the writings of Aristotle, the greatest philosopher of the ancient world, had been newly rediscovered and were becoming available to people in the West for the first time in a thousand years. Many feared that Aristotelianism was flatly contradictory to Christianity, and the fact that Aristotle’s works were coming to the West from mostly Muslim sources did nothing to help matters.

  Thomas’ clarity of thought ensured that the truth would be recognised whatever its source. He inaugurated a form of disputation which would bring ideas together not so that one would win and the other lose through clever tricks of debate, but so that the single unifying truth behind them should be found. He thus not only transformed the practice of theology but also laid the foundations of the modern scientific revolution.

  As well as producing major philosophical and theological works, Thomas, at the request of Pope Urban IV, composed the Divine Office for the newly-created feast of Corpus Christi.

  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.
