Do you believe that Jesus is the Christ, the Son of God, and that through that belief you will inherit eternal life? Belief begins with an intellectual assent but must continuously deepen. The belief Saint John speaks of in today’s Gospel is one that draws us deeper into the mystery of Christ’s Paschal Mystery—His Life, Death, and Resurrection—so as to receive the gift of His abundant and transforming Mercy. Today is the eighth day of Easter. The Church, in Her wisdom, celebrates the most important days of the liturgical year for eight days. Historically, there were a number of feasts celebrated with octaves: Easter, Epiphany, Corpus Christi, Ascension, All Saints, and in some locales, the Sacred Heart and various Marian feasts. After Vatican II, the Church focused on two—Christmas and Easter—so as to give greater emphasis to the core of the Paschal Mystery. In the year 2000, the Octave of Easter took on a new focus when Pope John Paul II instituted the Solemnity of Divine Mercy on the eighth day of Easter. This was done in response to Jesus’ personal request, communicated to the Church through a humble cloistered Polish nun. Canonized in 2000, she is known as Saint Maria Faustina Kowalska. Between 1931 and 1938, Sister Faustina received numerous mystical visions that she recorded in six notebooks, now referred to collectively as Divine Mercy in My Soul: Diary of Saint Maria Faustina Kowalska. Almost two years before her death, Sister Faustina recorded the following entry in her diary: On one occasion, I heard these words: “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 flows 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” (Diary #699). When we reflect on this beautiful private revelation in the light of today’s Gospel, we are invited to consider that even though the Gospels present us with all we need to know in order to come to faith in Christ and share in the new life He bestows, the treasure of His Divine Mercy is inexhaustible. Just as “Jesus did many other signs in the presence of his disciples that are not written in this book,” so also the depths of His ongoing work, His Divine Mercy, will only be seen in Heaven. Divine Mercy Sunday is a day on which we are to profess our belief in this Mercy. To do so, we must ponder these inexhaustible treasures, probe their depths with the aid of Saint Faustina’s private revelations, and then allow our Lord to reveal them to us within the depths of our souls. Reflect today on the infinite and inexhaustible treasures found in the Person of Christ and His Divine Mercy. His Mercy draws us into countless unrecorded and glorious graces that we are called to receive and rejoice in. Believe in His Mercy. Be open to it. Call upon it today, and receive it more abundantly. Most Merciful Jesus, Your mercy is so great that no mind, be it of man or of angel, will be able to fathom it throughout all eternity. On this Divine Mercy Sunday, I pray that You will pour out Your Mercy upon me and on the whole world. Fill us with the grace You won through Your Paschal Mystery so that all people will come to believe in You as their Lord and God. Jesus, I trust in You.
