Karol Józef Wojtyła was born in 1920 in Wadowice, Poland. After his ordination to the priesthood and theological studies in Rome, he returned to his homeland and resumed various pastoral and academic tasks. He became first auxiliary bishop and, in 1964, Archbishop of Kraków and took part in the Second Vatican Council. On 16 October 1978 he was elected pope and took the name John Paul II. His exceptional apostolic zeal, particularly for families, young people and the sick, led him to numerous pastoral visits throughout the world. Among the many fruits which he has left as a heritage to the Church are above all his rich Magisterium and the promulgation of the Catechism of the Catholic Church as well as the Code of Canon Law for the Latin Church and for the Eastern Churches. In Rome on 2 April 2005, the eve of the Second Sunday of Easter (or of Divine Mercy), he departed peacefully in the Lord. He was canonized by Pope Francis on 27 April, the Second Sunday of Easter 2014.

Augustine was born in Thagaste in Africa of a Berber family. He was brought up a Christian but left the Church early and spent a great deal of time seriously seeking the truth, first in the Manichaean heresy, which he abandoned on seeing how nonsensical it was, and then in Neoplatonism, until at length, through the prayers of his mother and the teaching of St Ambrose of Milan, he was converted back to Christianity and baptized in 387, shortly before his mother’s death.

The theological virtue of hope is symbolized by the colour green, just as the burning fire of love is symbolized by red. Green is the colour of growing things, and hope, like them, is always new and always fresh. Liturgically, green is the colour of Ordinary Time, the orderly sequence of weeks through the year, a season in which we are being neither single-mindedly penitent (in purple) nor overwhelmingly joyful (in white).
