Divine Mercy Sunday in time of pandemic.

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)

As we know, Christ is greater than the sacraments, and nothing can separate us from his love and mercy.  Therefore, even though we cannot attend Mass or receive the sacraments at this time, this feast has been established for the Second Sunday of Easter. In establishing the feast, the Church has decreed that a plenary indulgence can be received under the usual conditions; confession, communion, prayers for the Holy Father: Pater, Ave, Creed, and detachment from sin, etc. Click here for details.  Yet when impeded, the promises of Christ remain in effect, and the great pardon may still be obtained, as I will explain later.

In the revelations to St. Faustina, our Lord said this:

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 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) - Source

It is actually God's Mercy that conveys the necessary supernatural sorrow and resolution to amend.

It is generally understood that the confession of sin may take place any time during Lent, or as in the requirements for gaining a plenary indulgence, 8 days before or after the feast. Many people make a big deal about such "toties quoties" indulgences claiming that one has to be completely free of the least attachment to even venial sin in order to gain the indulgence or pardon. Good enough - but if that is the case, then you are probably already dead - so don't get too scrupulous over it. Trust in the Divine Mercy and never place limits upon God.

In other words - do not let anything stop you from running to the Divine Mercy with confidence and love. Our Lord himself established the feast to attract the greatest sinners, and even the not so great - the lukewarm, the fallen away, the sanctimonious, the CINO, the poor, the rich, the mentally ill, anyone!  Trust is the key. One does not have to be perfect - far from it.

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. - Source

From the Apostolic Penitentiary on March 20, 2020.

"New Plenary Indulgence:  Because of the pandemic, anyone who, with “the will to fulfil the usual conditions (sacramental confession, Eucharistic communion and prayer according to the Holy Father's intentions), as soon as possible,” recites the Divine Mercy Chaplet with the intention “to implore from Almighty God the end of the epidemic, relief for those who are afflicted and eternal salvation for those whom the Lord has called to Himself,” can receive a plenary indulgence each day." - Read more here.

The LORD’s acts of mercy are not exhausted,

his compassion is not spent;

They are renewed each morning—

great is your faithfulness!

The LORD is my portion, I tell myself,

therefore I will hope in him.l

The LORD is good to those who trust in him,

to the one that seeks him;

It is good to hope in silence

for the LORD’s deliverance. - Lamentations 3
