In 633 Oswald returned to Northumbria to regain his father’s kingdom. It was said that he set up a wooden cross as his standard and dedicated himself and his people to God’s protection before engaging himself in battle with the occupying Welsh King Cadwallon, not far from the present Hexham. He defeated and killed Cadwallon and at once invited the monks from Iona to begin the evangelisation of his kingdom which extended from the Forth to the Humber. After initial difficulties, the monk Aidan was sent to lead these Irish missionaries and Oswald found him to be both a valued adviser and a good friend. Oswald took seriously the work of bringing Christianity to his people and was even known to accompany Aidan on his missionary expeditions and to act as interpreter during the time Aidan was learning the language of the English. He was also well known both for his personal prayerfulness and his charity to those in need.

  Sadly the reign of King Oswald lasted only eight years. In 642 he was killed in battle by Penda the pagan king of the Mercians. It was said that as he fell in death he was heard to pray for those who died with him. Oswald was a popular hero and his reputation as a saint was widespread even into mainland Europe.

  He was a renowned scholar, compiling the Regularis Concordia and translating the Rule of Benedict into Old English. He used some of the wealth he accumulated to build new churches and was a great patron of ecclesiastical art. He died on 1 August 984 at Beddington in Surrey, and was buried in the Old Minster at Winchester. After a miraculous cure attributed to him some twelve years later, his body was moved from the crypt to the choir and he was recognized as a saint, though never formally canonized.

  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.
