Divine Mercy Sunday, the first Sunday after Easter, is a feast dedicated to opening ourselves up to God’s mercy.

Devotion to Christ’s divine mercy began with the visions of St. Faustina Kowalska. In 1930, while Faustina was praying in her room, Jesus appeared to her wearing a white robe with red and white rays emanating from his heart. He told her to have his image painted with these words inscribed below: “Jesus, I trust in you,” in Polish: “Jezu, ufam Tobie.” Jesus expressed his desire for a feast of Mercy to be established and for increased devotion to his abundant Divine Mercy.

Faustina began taking spiritual direction from the convent’s confessor, Fr. Michał Sopoćko, a professor of theology at Vilnius University. When Faustina told Fr. Michał of her visions, he recommended she be examined by a psychologist. After a number of tests, Faustina was declared to be of sound mind. Fr. Michał told Faustina to begin keeping a record of the visions and helped her find an artist to paint the image Jesus had requested.

In a later vision, Faustina recorded a series of prayers—the Chaplet of Divine Mercy—to be used in the devotion to the Divine Mercy. She wrote that the prayers served three purposes: to obtain mercy, to trust in Jesus’ mercy, and to show mercy to others.

Devotion to Divine Mercy spread quickly in popularity throughout the 1930s. In 1936, Faustina became critically ill with tuberculosis. As the disease slowly conquered her body, Faustina suffered intensely for several years. Her visions persisted, until she finally died on October 5, 1938, at the age of thirty-three.

After her death, the Vatican initiated an official inquiry into Faustina’s visions and diary, led by the Polish theologian Ignacy Rozycki. Faustina’s visions were approved as authentic and her diary was published first in Polish in 1981, lauded as “a document of Catholic mysticism of exceptional worth, not only for the Church in Poland, but also for the Universal Church.”

Devotion to the Divine Mercy was a source of strength for the Polish people who suffered greatly in World War II. In 1958, Pope Pius XII blessed the image of Jesus that Faustina had commissioned to be painted. In 1965, Archbishop Karol Wojtyla of Krakow initiated the review process of Faustina’s life and visions for canonization. When Archbishop Wojtyla was elected Pope John Paul II in 1978, he sped up the canonization process significantly: Faustina was beatified in 1993, and canonized in 2000.

As part of the canonization of Faustina, Pope John Paul II also declared the second Sunday of Easter as Divine Mercy Sunday. As Christ, in Faustina’s visions, had expressed his desire for that feast to celebrated.

“On that day, the very depths of My tender mercy are open. I pour out a whole ocean of graces upon those souls who approach the fount of My mercy. The soul that will go to Confession and receive Holy Communion shall obtain the complete forgiveness of sins and punishment. On that day all the divine floodgates through which grace flow are opened. Let no soul fear to draw near to Me, even though its sins be as scarlet.” (Diary, 699)

Today, we ask for God’s mercy for ourselves, that we might be streams of God’s mercy for others.

On this Divine Mercy Sunday, have mercy on us, O Lord, and on the whole world!

Closing Prayer of Divine Mercy Chaplet

Eternal God, in whom mercy is endless, and the treasury of compassion inexhaustible, look kindly upon us and increase your mercy in us, that, in difficult moments we might not despair, nor become despondent, but, with great confidence, submit ourselves to your holy will, which is love and mercy itself. Amen.
