Catholic Activity: The Feast of Mercy
The origin of the Feast of Divine Mercy, the Second Sunday after Easter, as revealed to St. Faustina.
Jesus said to Blessed Faustina Kowalska a Polish nun who died in 1938:
My daughter, Tell the whole world about My inconceivable mercy. I desire that the Feast of Mercy be a refuge and a 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. My mercy is so great that no mind, be it of man or of angel, will be able to fathom 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.
We can celebrate this "Mercy Sunday" by going to Confession (preferably before that Sunday) and by receiving Communion on that day. We can honor the mercy of the Lord by venerating the Image of The Divine Mercy, and by our prayers and works of mercy.
