Juana’s desire was realised on 7 May 1919, when she entered a tiny monastery of Discalced Carmelite Nuns in the township of Los Andes, some 90 kilometres away from her hometown of Santiago. On 14 October Juana was clothed in the Carmelite habit and began her novitiate with the religious name Teresa of Jesus. She expressed a fervour for her mission to make God known and loved. Early in the following year Sister Teresa contracted typhus and faced both interior struggles and physical suffering. On 7 April, because of danger of death, she made her religious profession and soon after, on the evening of 12 April 1920, entered into the loving embrace of the God she desired. Juana’s life on earth was short, but like those Carmelites named Teresa before her, she discovered the simplicity of faith in living, believing and loving.

  In 374 the bishopric of Milan fell vacant and when Ambrose tried to pacify the conflict between the Catholics and Arians over the appointment of a new bishop, the people turned on him and demanded that he become the bishop himself. He was a layman and not yet baptized (at this time it was common for baptism to be delayed and for people to remain for years as catechumens), but that was no defence. Coerced by the people and by the emperor, he was baptized, ordained, and installed as bishop within a week, on 7 December 374.

  He immediately gave his money to the poor and his land to the Church and set about learning theology. He had the advantage of knowing Greek, which few people did at that time, and so he was able to read the Eastern theologians and philosophers as well as those of the West.

  He was assiduous in carrying out his office, acting with charity to all: a true shepherd and teacher of the faithful. He was unimpressed by status and when the Emperor Theodosius ordered the massacre of 7,000 people in Thessalonica, Ambrose forced him to do public penance. He defended the rights of the Church and attacked the Arian heresy with learning, firmness and gentleness. He also wrote a number of hymns which are still in use today.

  Ambrose was a key figure in the conversion of St Augustine to Catholicism, impressing Augustine (hitherto unimpressed by the Catholics he had met) by his intelligence and scholarship. He died on Holy Saturday, 4 April 397.

  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.
