Feast of Divine Mercy
According to Jesus' wish, the Feast of Mercy is to be celebrated on the first Sunday after Easter. Jesus is showing us the close connection between the Easter mystery of man's Redemption and this feast. The liturgy for this day extols God most fully in the mystery of His mercy.
The Feast of Mercy is to be not only a day designated for the singular worship of God's Mercy , but also a day of grace for all people, particularly for sinners. Jesus attached great promises to this feast, the greatest of which is connected with the reception of Holy Communion on that day. It is the promise of complete forgiveness of sins and punishment. In other words, this grace is equal only to the one we receive in the Sacrament of Holy Baptism. The greatness of this feast lies also in the fact that everyone, even those who are converted that very day, may obtain any grace for the asking, if what they ask for be compatible with God's will.
I want this image, Jesus told Sister Faustina, to be solemnly blessed on the first Sunday after Easter; that Sunday is to be the Feast of Mercy. (49) 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 are open all the divine floodgates through which graces flow. Let no soul fear to draw near to Me, even though its sins be as scarlet. (699)
The Feast of My Mercy has issued forth from My very depths for the consolation of the whole world (1517) and is confirmed in the vast depths ofmy tender mercies. (420)
The preparation for this feast is to be a novena consisting of the recitation of the Divine Mercy Chaplet for nine days, beginning on Good Friday.
