Saint Faustina’s diary contains at least fifteen passages in which Our Lord is quoted as requesting that a “Feast of Mercy” be officially established in the Church. He declared:
The Feast emerged from My most tender pity and it is confirmed in the depths of My mercy…I desire that it be celebrated with great solemnity on the first Sunday after Easter…I desire that the Feast of Mercy be a refuge and shelter for all souls, and especially for poor sinners. The very depths of My tender mercy are open on that day. I pour out a whole ocean of graces upon souls who will approach the fount of My mercy. (I, 175; II,138)
To the celebration of the Feast of Jesus attached:
The soul that will go to Confession and receive Holy Communion [on that day] shall obtain complete forgiveness of sins and punishment…Let no soul fear to draw near to Me, even though its sins be as scarlet (II, 138).
