In this post, Divine Mercy Sunday is better than a plenary indulgence!, I go on about how, well, Divine Mercy Sunday is better than a plenary indulgence. (It was easy to come up with the title.) All of this is based on the teachings of Fr. Chris Alar of the Marians of the Immaculate Conception. He has videos all over their YouTube Channel, many on Divine Mercy and on Divine Mercy Sunday. 

In his videos he describes how Divine Mercy Sunday is better than a plenary indulgence (I’m being repetitive to impress upon you that point.) To summarize what he says (and this is all derived from what Jesus told St. Faustina, nothing at all is his innovation):

1) Go to Confession before Divine Mercy Sunday (could be a few days or so, as long as you remain in a state of grace, i.e. no mortal sins.)
2) Go to Mass on Divine Mercy Sunday (Saturday Vigil Mass counts, as that covers Sunday.)
3) Recieve Holy Communion
4) He added this prayer (this is his own composition, not found in the Diary or St. Faustina’s writings, but there’s nothing wrong with it):

“Lord Jesus Christ, Son of the living God, have mercy on me, a poor sinner: Jesus, you promised St. Faustina that the soul who has been to confession [l have] and the soul that receives Holy Communion [I just did], will receive the complete forgiveness of all sin and punishment.
Please give me this grace.”

Here it is as a JPEG, you can right-click and save it to your device to use to pray after Communion.

Jesus told St. Faustina, which she recorded in her diary:

300 +Ask of my faithful servant [Father Sopocko] that, on this day, he tell the whole world of My great mercy; that whoever approaches the Fount of Life on this day will be granted complete remission of sins and punishment.

+Mankind will not have peace until it turns with trust to My mercy.

+Oh, how much I am hurt by a soul’s distrust! Such a soul professes that I am Holy and Just, but does not believe that I am Mercy and does not trust in My Goodness. Even the devils glorify My Justice but do not believe in My Goodness. My Heart rejoices in this title of Mercy.

Furthermore:

699 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. On that day all the divine floodgates through which
 graces 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 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.

And:

1109 …

Immediately upon my awakening, God‟s presence enveloped me, and I felt I was a child of God. Divine love was poured into my soul, and God gave me to see how everything depended on His will. He spoke these words to me: I want to grant a complete pardon
to the souls that will go to Confession and receive Holy Communion on the Feast of My mercy. Then he said to me, My daughter, fear nothing. I am always with you, even if it seems to you that I am not. Your humility draws Me down from My lofty throne, and I unite Myself closely with you.

For your benefit, this is the Plenary Indulgence requirements, if you prefer that route (but why would you? Divine Mercy Sunday is better than a plenary indulgence!):

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.

Indulgences attached to Divine Mercy Devotion.

More on the Plenary Indulgences – General Conditions. It is good to note No. 7:

Indulgences can always be applied either to oneself or to the souls of the deceased, but they cannot be applied to other persons living on earth.

That may be a good reason to try and satisfy the “formal” method for obtaining the plenary indulgence; you can apply it to a holy Soul in Purgatory. As to a question of whether you can receive the Special Graces promised by Jesus for yourself, but transfer the graces of the plenary indulgence to a Holy Soul in Purgatory? I honestly do not know. I just emailed the Divine Mercy people and asked it and UPDATE!!!!—> I received a reply today, April 10th, the very next day! 

This is what I asked: 

Can someone receive the special graces of Divine Mercy Sunday as promised by Jesus to St. Faustina for oneself, BUT also satisfy the requirements for the plenary indulgence and apply that to a Holy Soul in Purgatory?

And their reply:

Yes, someone can receive the graces of Divine Mercy Sunday for oneself if they intend to receive the Extraordinary Promise of Divine Mercy Sunday.

If they wish to apply the plenary indulgence (a different grace on this day) to a soul in purgatory, they can also do that as well as long as they know there are more requirements for an indulgence (prayer for the Pope’s intentions, doing an indulgent act like venerating the image or participating in Divine Mercy devotions, complete and total detachment for sin, and confession).

For more information, please see these articles:

So, we can reserve the Special Graces for ourselves, but if we also satisfy the Church’s requirements for the plenary indulgence, apply those to a holy soul in purgatory! Wow. God is good.
