The Indissoluble Bond with Saint Faustina Kowalska
The role of John Paul II in spreading the devotion was providential. From the time of his episcopate in Krakow, he understood the prophetic scope of the Diary of a humble Polish nun, who was then almost unknown to the general public.
It was he who promoted the process of information on the life and virtues of Sister Faustina Kowalska, leading her first to beatification (April 18, 1993) and then to the solemn canonization on April 30, 2000. In that historic day, the Pope officially instituted the Feast of Divine Mercy for the entire universal Church, to be celebrated on the first Sunday after Easter.
“The light of the message of divine mercy will illumine the way for the men and women of the third millennium” (John Paul II, April 30, 2000).

Pilgrimages to the Places of Mercy
Saint John Paul II physically retraced the steps of the “Secretary of Mercy,” linking his pontificate to symbolic shrines and cities.
1. Krakow-Łagiewniki (Poland): The World Center of the Devotion
The Sanctuary of Łagiewniki is the place where Saint Faustina lived her final years and where her remains are kept. The Pope visited it at crucial moments:
- June 7, 1979: During his first apostolic journey to Poland, he stopped in prayer before the image of Divine Mercy.
- August 17, 2002: On his last trip to his homeland, he solemnly consecrated the new Sanctuary of Divine Mercy, entrusting the entire world to Divine Mercy with an act of entrustment that has remained in history.
2. Vilnius (Lithuania): The City of the First Image
Vilnius is the place where Jesus appeared to Sister Faustina asking her to paint the image with the inscription “Jesus, I trust in You.”
September 4-8, 1993: During his historic journey to the Baltic Republics, the Pope visited Vilnius. He stopped in prayer at the Gate of Dawn and visited the sites linked to the presence of Sister Faustina and her confessor, Blessed Michael Sopoćko. On that occasion, he emphasized how the message of Mercy was the bridge for reconciliation between the peoples of the East.
The Theology of Mercy: The Encyclical “Dives in Misericordia”
It is impossible to speak of Saint John Paul II without mentioning his second encyclical, Dives in Misericordia (1980). In this document, the Pope delves into the biblical and theological concept of mercy, presenting it not as a weak sentiment, but as the highest manifestation of God’s justice and love toward man wounded by sin.
Why rely on Saint John Paul II today?
Saint John Paul II died on the very eve of Divine Mercy Sunday in 2005. His entire existence was a sign: he showed that even in suffering and illness, trust in Merciful Jesus grants a peace that the world cannot give.
