The Sunday after Easter is Divine Mercy Sunday a Day of Extraordinary Grace. All of Lent is a preparation for the most important feast of Easter, but we actually celebrate it over eight full days, which is why we call it the Octave of Easter. The Second Sunday of Easter, Mercy Sunday is the last day of the octave, the eighth day
In a series of revelations to Saint Maria Faustina Kowalska, Our Lord repeatedly called for the celebration of the Feast of Mercy on the first Sunday after Easter. Specifically he told St. Faustina : “...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 [Divine Mercy Sunday], the very depths of My tender mercy are opened. I pour out a whole ocean of graces upon those souls who approach the fount of My mercy...On that day, all the divine floodgates through which graces flow are opened. The soul that will go to confession and receive Holy Communion shall obtain complete forgiveness of sins and punishment.)”
“Ordinarily, only the sacrament of Baptism effects in the soul the 'complete forgiveness of sins and punishment.' Reception of the Eucharist in a state of grace ordinarily remits only venial sin, strengthening the soul against both venial and mortal sin(Catechism, 1394, 1394-1395). But on Mercy Sunday reception of Holy Communion worthily and with trust in God's Mercy pours out upon the soul a complete renewal of baptismal grace.” Rev. Ignacy Rozycki, STD, Former Member of the Holy See's International Commission
To receive the special graces of Divine Mercy Sunday:
Place complete trust in God's mercy
Repent of all your sins and go to Confession within a reasonable time before or on the Feast (during Lent suffices)
Celebrate God's mercy by attending Mass and receiving Holy Communion(as always, while in the state of grace (no mortal sin) on Divine Mercy Sunday or the vigil
Venerate the image of The Divine Mercy
Be merciful to others, by our actions, words, or prayers.
“The graces of My Mercy are drawn by Trust. The more a soul trusts, the more it will receive.” (Our Lord to St. Faustina) If you are homebound, can't receive the Eucharist, not Catholic, need to
