The Lord Jesus chose Sr. Maria Faustina as the Apostle and "Secretary" of His Mercy, so that she could tell the world about His great message, which Sr. Faustina recorded in a diary she titled Divine Mercy in My Soul. In the Old Covenant He said to her:"I sent prophets wielding thunderbolts to My people. Today I am sending you with My mercy to the people of the whole world. I do not want to punish aching mankind, but I desire to heal it, pressing it to My Merciful Heart." (Diary, 1588)In an extraordinary way, Sr. Maria Faustina's work sheds light on the mystery of the Divine Mercy. It delights not only the simple and uneducated people, but also scholars who look upon it as an additional source of theological research. The Diary has been translated into more than 20 languages, including, English, German, Italian, Spanish, French, Portuguese, Arabic, Russian, Hungarian, Czech, Slovak, Polish, Castilian, Brazilian, Vietnamese, Korean, Chinese, Swedish, Ukrainian, Dutch and Japanese.Sister Maria Faustina, consumed by tuberculosis and by innumerable sufferings which she accepted as a voluntary sacrifice for sinners, died in Krakow at the age of just 33 on October 5, 1938, with a reputation for spiritual maturity and a mystical union with God. The reputation of the holiness of her life grew as did the cult to the Divine Mercy and the graces she obtained from God through her intercession. In the years 1965-67, the Investigative Process into her life and heroic virtues was undertaken in Krakow and in the year 1968, the Beatification Process was initiated in Rome. The latter came to an end in December 1992.On April 18, 1993 our Holy Father, John Paul II raised St. Faustina to the glory of the altars. She was canonized on April 30, 2000. St. Maria Faustina's remains rest at the Sanctuary of the Divine Mercy in Krakow-Lagiewniki.
