Among all of the elements of devotion to the Divine Mercy requested by our Lord through St. Faustina Kowalska, the Feast of Mercy holds first place. The Lord's will with regard to its establishment was already made known in His first revelation to the saint, as recorded in her Diary. In all, there were 14 revelations concerning the desired feast. The most comprehensive revelation can be found in Diary entry 699:
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 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.
Our Lord's explicit desire is that this feast be celebrated on the first Sunday after Easter. This Sunday is designated in the liturgy as the Octave Day of Easter. It was officially called the Second Sunday of Easter after the liturgical reform of Vatican II. Now, by the Decree of the Congregation for Divine Worship and the Discipline of the Sacraments, the name of this liturgical day has been changed to: Second Sunday of Easter, or Divine Mercy Sunday.
Saint John Paul II made the surprise announcement of this change in his homily at the canonization of St. Faustina on 30th April 2000. There, he declared: "It is important then that we accept the whole message that comes to us from the word of God on this Second Sunday of Easter, which from now on throughout the Church, will be called 'Divine Mercy Sunday.'"
Liturgically the Easter Octave has always been centered on the theme of Divine Mercy and forgiveness. Divine Mercy Sunday, therefore, point us to the merciful love of God that lies behind the whole Paschal Mystery – the whole mystery of the death, burial and resurrection of Christ – made present for us in the Eucharist. In this way, it also sums up the whole Easter Octave. As Saint John Paul II pointed out in his Regina Caeli address on Divine Mercy Sunday, 1995: "the whole Octave of Easter is like a single day," and the Octave Sunday is meant to be the day of "thanksgiving for the goodness God has shown to man in the whole Easter mystery."
How to prepare to and celebrate Divine Mercy Sunday
Jesus asked Sr. Faustina to pray the special novena as a preparation to the Feast of the Divine Mercy:
I desire that during these nine days you bring souls to the fountain of My mercy, that they may draw there from strength and refreshment and whatever grace they have need of in the hardships of life, and especially at the hour of death. (1209)
The novena to the Divine Mercy is typically nine days of prayer with a specific Intention for each day and followed by the Chaplet. The Chaplet can be said anytime, but the Lord specifically asked that it be recited as a novena. He promised:
By this Novena (of Chaplets), I will grant every possible grace to souls. (796)
Thus, to fittingly observe the Feast of Mercy, we should:
- Celebrate the Feast on the Sunday after Easter;
- Sincerely repent of all our sins;
- Place our complete trust in Jesus;
- Go to confession, preferably before that Sunday;
- Receive Holy Communion on the day of the Feast;
- Venerate the Image of the Divine Mercy;
- Be merciful to others, through our actions, words, and prayers on their behalf.
