Sister Faustina wanted to be a great saint, raised to the glory of the altar (Cf. Diary 150). Many a time not only did she write about this desire but also unwaveringly strove to be a saint. Her determination was unusual. She wrote: “My Jesus, You know that from my earliest years I have wanted to become a great saint; that is to say, I have wanted to love You with a love so great that there would be no soul who has hitherto loved You so” (Diary 1372).
On the 5th October 1938, when she died at the age of only 33, she was considered to be a saint. The reputation of the sanctity of her life was growing along with the developing devotion to the Divine Mercy in the forms conveyed by her. Pilgrims came to her tomb, to the monastic cemetery in Cracow-Łagiewniki, and obtained many graces through her intercession.
On the 21st October, 1965, Bishop Julian Groblicki, delegated by the Archbishop of Cracow, Cardinal Karol Wojtyła, began with a solemn session the Informative Process relating to the life and virtues of Sister Faustina, during which 45 witnesses to her life were interviewed, the writings were collected and the process regarding the absence of public devotion was conducted. On the 25th November, 1966, the mortal remains of the Servant of God were translated from the tomb, from the monastic cemetery, to the chapel. On the 20th September, 1967, Cardinal Karol Wojtyła chaired a solemn session which closed the Informative Process on the diocesan level. The acts of the process were sent to Rome and on the 31st January, 1968, the Congregation for the Causes of Saints inaugurated the Process of Beatification. On the 7th March, 1992, the Holy Father, John Paul II, promulgated a decree on the heroic virtues and on the 21st December of that year he issued a decree regarding a miracle. He also fixed the date for the beatification in Rome to be the 18th April, 1993.
Many years before the beatification, in the ‘Diary’ Sister Faustina described her way to the glory of the altar in the following manner: “Once I saw a big crowd of people in our chapel, in front of the chapel and in the street, because there was no room for them inside. The chapel was decorated for a feast. There were a lot of clergy near the altar, and then our sisters and those of many other congregations. They were all waiting for the person who was to take a place on the altar. Suddenly I heard a voice saying that I was to take the place on the altar. But as soon as I left the corridor to go across the yard and enter the chapel, following the voice that was calling me, all the people began to throw at me whatever they had to hand: mud, stones, brooms, to such an extent that I at first hesitated to go forward. But the voice kept on calling me even more earnestly, so I walked on bravely. When I entered the chapel, the superiors, the sisters, the students, and even my parents started to hit me with whatever they could, and so whether I wanted to or not, I quickly took my place on the altar. As soon as I was there, the very same people, the students, the sisters, the superiors and my parents all began to hold their arms out to me asking for graces; and as for me, I did not bear any grudge against them for having thrown all sorts of things at me, and I was surprised that I felt a very special love precisely for those persons who had forced me to go more quickly to my appointed place. At the same time my soul was filled with ineffable happiness, and I heard these words: ‘Do whatever you wish, distribute graces as you will, to whom you will and when you will’. Then, instantly, the vision disappeared” (Diary 31).
