La Festa de Divina Misericordia

From the Diary of St. Faustina:

Whoever approaches the Fountain of Life on this day will be granted complete forgiveness of sins and punishment. (Diary 300)

I want the image solemnly blessed on the first Sunday after Easter, and I want it to be venerated publicly so that every soul may know about it. (Diary 341)

This Feast emerged from the very depths of My mercy, and it is confirmed in the vast depths of my tender mercies. (Diary 420)

On one occasion, I heard these words: My daughter, tell the whole world about My Inconceivable mercy. I desire that the Feast of Mercy be a refuge and shelter for all souls, and especially for poor sinners. 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 complete forgiveness of sins and punishment.* [our emphasis] 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. My mercy is so great that no mind, be it of man or of angel, will be able to fathom it throughout all eternity. Everything that exists has come forth from the very depths of My most tender mercy. Every soul in its relation to Me will I contemplate My love and mercy throughout eternity. The Feast of Mercy emerged from My very depths of tenderness. It is My desire that it be solemnly celebrated on the first Sunday after Easter. Mankind will not have peace until it turns to the Fount of My Mercy. (Diary 699)

Yes, the first Sunday after Easter is the Feast of Mercy, but there must also be deeds of mercy, which are to arise out of love for Me. You are to show mercy to our neighbors always and everywhere. You must not shrink from this or try to absolve yourself from it. (Diary 742)

I want to grant complete pardon to the souls that will go to Confession and receive Holy Communion on the Feast of My mercy. (Diary 1109)

Divine Mercy Sunday Indulgence (Promulgated on 29 June 2002, the Apostolic Penitentiary of the Holy See)
And so the Supreme Pontiff, motivated by an ardent desire to foster in Christians this devotion to Divine Mercy as much as possible in the hope of offering great spiritual fruit to the faithful, in the Audience granted on 13 June 2002, to those Responsible for the Apostolic Penitentiary, granted the following Indulgences:

a plenary indulgence, granted under the usual conditions (sacramental confession, Eucharistic communion and prayer for the intentions of Supreme Pontiff) to the faithful who, on the Second Sunday of Easter or Divine Mercy Sunday, in any church or chapel, in a spirit that is completely detached from the affection for a sin, even a venial sin, take part in the prayers and devotions held in honour of Divine Mercy, or who, in the presence of the Blessed Sacrament exposed or reserved in the tabernacle, recite the Our Father and the Creed, adding a devout prayer to the merciful Lord Jesus (e.g. Merciful Jesus, I trust in you!");

A partial indulgence, granted to the faithful who, at least with a contrite heart, pray to the merciful Lord Jesus a legitimately approved invocation.

For those who cannot go to church or the seriously ill

In addition, sailors working on the vast expanse of the sea; the countless brothers and sisters, whom the disasters of war, political events, local violence and other such causes have been driven out of their homeland; the sick and those who nurse them, and all who for a just cause cannot leave their homes or who carry out an activity for the community which cannot be postponed, may obtain a plenary indulgence on Divine Mercy Sunday, if totally detesting any sin, as has been said before, and with the intention of fulfilling as soon as possible the three usual conditions, will recite the Our Father and the Creed before a devout image of Our Merciful Lord Jesus and, in addition, pray a devout invocation to the Merciful Lord Jesus (e.g. Merciful Jesus, I trust in you).

If it is impossible that people do even this, on the same day they may obtain the Plenary Indulgence if with a spiritual intention they are united with those carrying out the prescribed practice for obtaining the Indulgence in the usual way and offer to the Merciful Lord a prayer and the sufferings of their illness and the difficulties of their lives, with the resolution to accomplish as soon as possible the three conditions prescribed to obtain the plenary indulgence.
