Apart from the “Diary”, Saint Faustina has also left the letters and cards with wishes. Among the letters which have been preserved until today, we find: 19 letters which she sent to Rev. Michael Sopoćko – her spiritual director from Vilnius; 1 letter to Father Joseph Andrasz, S.J. – her confessor and spiritual director in Cracow; 3 letters to the Superior General, Mother Michaela Moraczewska; 1 letter to the house superior in Cracow, Mother Irena Krzyżanowska; 9 letters to Sister Justyna Gołofit, whom Sister Faustina had looked after in the spiritual sense, acting as a so-called “Angel”; 11 letters to Sister Ludwina Gadzina for whom Saint Faustina was also an “Angel”; and 1 letter to Sister Beniamina Zarębska. In the Congregation archive there are also cards with short, rhymed wishes addressed to Mother Irena Krzyżanowska and some other sisters. Occasional letters to her family have also been preserved: to her sisters Eugenia, Natalia and Wanda, as well as dedications on holy cards for her parents. In the book “The Letters of Saint Faustina” there are also 9 letters which Michael Sopoćko sent to her. They have been published as they do not only enable the reader to see what the relationship between Sister Faustina and Father Sopoćko was like but, above all, they also show their mutual efforts to discern God’s will as well as their common pursuits pertaining to the fulfilment of the mission of the Apostle of Divine Mercy. The letters, wishes, dedications on holy cards reveal and complete the spiritual portrait of the Apostle of the Divine Mercy. They reveal the countenance of a mystic and prophet totally involved in the cause of proclaiming the message of Mercy to the world and, at the same time, they show a person who is really and truly concerned about man, his salvation and human needs.
