St. Faustina Kowalska, the Nun
She was Helena Kowalska before the adoption of the monastic name. All her life she was modest and smiling and trusting God. At the monastery, she worked in the kitchen, the garden and the entrance gate. But this simple and uneducated woman was entrusted with a unique mission. The world may know St. Faustina as the apostle of God’s Mercy - is was through her that Jesus gave to the Church and the world the message she wrote in her "Diary" – a bestseller translated into more than 30 languages. People were called to trust in the Lord and show mercy toward one's neighbors, and to proclaim and implore God's Mercy for the world, through the practice of new forms of worship (the miraculous image of Merciful Jesus, "In Jesus We Trust," Feast of Mercy on the first Sunday after Easter, chaplet of Divine Mercy and the Hour of Mercy).
Sister Faustina’s mission was continued by Pope John Paul II. On 30 April 2000 he declared her a saint. On that occasion, he said, "Today I experience a great joy, revealing to the whole Church the life and witness of Sister Faustina Kowalska, as a gift of God for our times. (...) Through this canonisation, I would like today to convey the Message of Mercy to the new millennium. I pass it on to all people, to learn to know ever better the true face of God and man."
