Estrangement Meets Mercy
Divine Mercy Sunday: Finding Forgiveness and Healing in Family Estrangement – Lessons from St. Faustina’s Diary
Every year, the Sunday after Easter brings us Divine Mercy Sunday—a feast day given to the Church through the visions and writings of St. Maria Faustina Kowalska. It’s not just another holy day on the calendar. It’s a profound invitation from Jesus Himself to plunge into the depths of God’s Mercy, especially when life feels shattered by pain, rejection, or loss. For me, this feast hits especially close to home because of a wound that still aches: my sisters cutting me out of their lives after my brain injury, right in the middle of their teenage rebellion.
St. Faustina’s Diary: Divine Mercy in My Soul records Jesus’ own words about this day with breathtaking clarity. In entry 699, He tells her:
“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 graces flow are opened.”
Jesus doesn’t mince words. He calls this the day when mercy itself becomes a shelter—a safe harbor for the broken, the angry, the rebellious, and the hurting. He promises an ocean of graces to anyone who simply approaches with trust. And He ties it directly to peace in our lives: “Mankind will not have peace until it turns with trust to My mercy” (Diary 300).
That promise has become my lifeline.
Several years ago, a brain injury changed everything for me—my personality, my energy, my ability to show up the way I once did. Around the same time, my younger sisters were deep in teenage rebellion. Hurt, confused, and maybe even scared by how different I seemed, they made the choice to cut me out completely. No calls. No visits. No explanations that ever felt complete. The rejection cut deeper than the injury itself. Family should be the one place you can count on, right? Instead, I was left grieving someone who was still alive but chose to be gone. The silence that followed has been one of the deepest pains I’ve known: a living grief where someone you love draws a firm unexplained boundary and walks away.
For a long time, I wrestled with anger, sadness, and questions of “why” lingered. How do you forgive someone who doesn’t even want your forgiveness? How do you keep loving when the other person has drawn a hard line? How do you keep your heart open when the other person has closed the door? I learned to forgive, to love without knowing, and my heart has always remained for them.
St. Faustina’s Diary gently redirects that pain toward trust and mercy. Jesus emphasizes that trust is the single vessel that draws His graces. In Diary 1578:
“The graces of My mercy are drawn by means of one vessel only, and that is—trust. The more a soul trusts, the more it will receive. Souls that trust boundlessly are a great comfort to Me, because I pour all the treasures of My graces into them.”
Trust here is not a warm emotion. It is a deliberate choice to believe that God’s mercy is larger than my brain injury, larger than my sister’s rebellion, and larger than the resulting fracture between us. When I approach Him with that trust—especially on Divine Mercy Sunday—He promises to take care of the soul that trusts.
That’s where St. Faustina’s Diary opened my eyes. Jesus doesn’t ask us to manufacture warm feelings or pretend the hurt never happened. He asks us to trust His mercy enough to become merciful ourselves. In entry 1148, St. Faustina records: “We resemble God most when we forgive our neighbors.” And in another powerful passage (Diary 723), Jesus reminds us that “the greater the sinner, the greater the right he has to My mercy.” My sister wasn’t a “sinner” in some dramatic sense—she was a scared teenager navigating her own chaos and fear of the consequences of her decisions, while I was struggling in mine. Yet even though her decisions caused real harm against me, she—and I, in my own imperfections—stand under that same promise. The abyss of God’s mercy is deep enough for both of us.
Divine Mercy Sunday reminds me that I don’t have to wait for my sister to make things right or come back before I can find peace. Mercy isn’t a transaction; it’s a gift I can receive and then freely give. On this feast, I go to Confession, receive Communion, and lay the whole mess at the foot of the Cross: the brain injury, the lost relationship, the unanswered texts, the never calling desiring to talk, the empty chair at family gatherings. I ask Jesus to flood my heart with the same ocean of grace He promises. And then I pray for her—by name, like I have every day for the last 14 years. I ask the Lord to heal whatever pain or fear still keeps her away from our family that loves her so deeply. I choose, even in silence, to forgive again and again.
Forgiving doesn’t require the other person to return. It doesn’t erase the injury or pretend the distance doesn’t hurt. It means laying the entire situation—my limitations after the brain injury, her teenage choices, the lost years—at the foot of the Cross and choosing, with God’s help, not to let bitterness take root. Looking at the Crucified Christ makes it possible to forgive “with all my heart,” even if only in prayer for now. Even while my sister chooses to remain distant, my choosing trust on Divine Mercy Sunday allows God’s graces to radiate—perhaps softening hearts in ways I cannot see, or at least freeing my own heart to love without resentment.
Some days that forgiveness feels like a quiet victory. Other days it feels impossible. But every time, Jesus meets me there in the impossibility. He tells Faustina (and all of us): “My Heart overflows with great mercy for souls, and especially for poor sinners” (Diary 699). My sister is included in that “especially.” So am I. So is every one of us who has ever failed or been failed by someone we love.
If you’re carrying a similar wound—estrangement, betrayal, a family member who walked away—Divine Mercy Sunday is for you too. You don’t have to fix the relationship today. You only have to approach the Fount of Mercy with trust, mercy, and forgiveness. Let Jesus do the heavy lifting. Let His ocean of graces wash over the places in your heart that still feel dry and cracked.
This Sunday, as churches around the world celebrate the Feast of Divine Mercy, I’ll be praying the Chaplet of Divine Mercy and whispering the simple prayer that St. Faustina taught us: “Jesus, I trust in You.” I’ll trust Him with my sister’s heart. I’ll trust Him with mine. And I’ll trust that the same mercy that can forgive the greatest sins can also heal the deepest family rifts—in His time, in His way.
If you’re reading this and carrying your own story of loss or rejection, know that you are not alone. The Divine Mercy is real, it is personal, and it is bigger than any injury—physical or relational. Come to the feast. Approach the Fount. Let the ocean of graces do what only God can do.
Jesus, I trust in You.
“Eternal God, in whom mercy is endless and the treasury of compassion — inexhaustible, look kindly upon us and increase Your mercy in us, that in difficult moments we might not despair nor become despondent, but with great confidence submit ourselves to Your holy will, which is Love and Mercy itself. Amen”
