Divine Mercy Sunday been given for total forgiveness of sins will one mortal sins will remove the grace

Divine Mercy Sunday offers the extraordinary grace of complete remission of sins and punishment (like a second baptism), wiping the soul clean. While it removes all past guilt and punishment, committing a new mortal sin afterward will separate you from God and remove sanctifying grace, requiring sacramental confession to restore it. 

• The Promise: Jesus promised that a soul that goes to Confession and receives Holy Communion on Divine Mercy Sunday will obtain total forgiveness of all sins and punishment.

• Effect of Mortal Sin: Mortal sin destroys sanctifying grace in the soul. It breaks the relationship of friendship with God, meaning that even after the graces of Divine Mercy Sunday, a new mortal sin brings spiritual death.

• The Remedy: If a mortal sin occurs after receiving this grace, the soul is restored to a state of grace through the Sacrament of Reconciliation (Confession).

• Conditions: To receive the grace, one must go to Confession (within a reasonable time before/on the day), receive Holy Communion worthily, trust in His mercy, and perform acts of mercy.

The grace received on Divine Mercy Sunday makes the soul spotlessly clean, requiring us to guard that grace through a virtuous life.

If the act was a mortal sin, it removes the state of sanctifying grace from your soul. For a sin to be mortal, three conditions must be met:

1. Grave Matter: The Church teaches that masturbation is grave matter.

2. Full Knowledge: You knew it was a serious sin against God's law.

3. Complete Consent: You gave a deliberate, free choice of the will to do it. 

Understanding Culpability

The Catechism of the Catholic Church (CCC 2352) notes that factors like force of habit or anxiety can sometimes reduce your personal "culpability" (guilt). However, even if your guilt is reduced, the act remains "gravely disordered," and the best path for peace of mind is to return to God's mercy as soon as possible. 

What to do now

• Go to Confession: This is the ordinary way to restore sanctifying grace if it has been lost. You do not have to wait for another special feast; the "ocean of mercy" is available in every Sacramental Confession.

• Avoid Presumption: Avoid the thought that you can sin because mercy is always there. True repentance includes a firm resolution to avoid the sin in the future.

• Do Not Despair: Jesus' mercy did not end on Divine Mercy Sunday. He is always ready to forgive a heart that sincerely asks for it. 

Want to know if a regular confession works after the feast?

Yes, a regular confession works perfectly to restore the grace lost after the feast. While the specific promise of Divine Mercy Sunday—the total remission of both sins and punishment—is unique to that day, the Sacrament of Reconciliation remains the ordinary and constant "miracle of mercy" given by Jesus for any time we fall.

• Restoration of Grace: Sacramental confession restores "sanctifying grace" to the soul after a mortal sin, making you spiritually alive again and fit to receive Holy Communion.

• Healing the Soul: Regular confession not only forgives the guilt of the sin but also provides specific spiritual strength to help you resist future temptations.

• No Limit to Mercy: Jesus' mercy does not end after Divine Mercy Sunday. He instituted Confession precisely because He knew we are weak and would need to be reconciled with Him multiple times.

• Hope and Peace: Approaching the sacrament with a sincere and humble heart will remove the burden of guilt and bring back the peace and joy of God's friendship.
