“Proclaim that mercy is the greatest attribute of God.”
– Jesus to St. Faustina
Devotion to Divine Mercy is not every Catholic’s thing. Some people struggle with the image of Divine Mercy: Jesus, His right hand raised to bless and heal, His left indicating his heart, from which rays of red and white, symbolizing blood and water, pour forth as a fountain of mercy for souls. Every version I’ve seen has been a bit mysterious and unsettling—which seems appropriate, given that it’s a vision of the resurrected Christ.
Some don’t like the chaplet, which is simpler and more repetitious than the rosary. Some consider the visions of a poor Polish nun to be private revelations: fine for her, but not necessary for us (even though she is a saint and was canonized by another saint).
And some struggle with the emphasis on God’s mercy, seemingly at the expense of His justice or even over His love. At first blush, saying that “mercy is God’s greatest attribute” (Diary of St. Faustina, 300) appears to downplay the seriousness of sin and the need for repentance. It suggests—much to the comfort of some sinners—that God will invariably forego His justice. It seems presumptuous.
But let’s think about what love, justice, and mercy actually are. Love, we are told, is willing the good of another regardless of the cost to yourself. Justice is giving another what is due. Mercy is often regarded as a bridge between these two: sparing someone just punishment for his or her benefit.
Because God is infinitely good, justice requires complete goodness from us in return. That is God’s due. But we are all sinners, and even the smallest sin stands in stark contrast to God’s infinite goodness—a grave injustice toward One who loves us perfectly.
What is our due as a result of this? Condemnation. We ought to suffer, not out of retribution, but as the natural consequence of our sins.
So God’s mercy does not deny the reality of sin or the need for repentance. Instead, it depends on these things. Without the grave reality of sin and the suffering that justly results from it, we would have no need of mercy. God’s mercy exists because of sin. There is no other reason.
But how can God be perfectly loving, perfectly just, and perfectly merciful—all at the same time? And how can mercy be God’s greatest attribute, when Scripture tells us that God is love (1 John 4:8)?
Look at it this way:
- If God is love, then His very nature is to will our good, whatever the cost to Himself.
- What is our good? Ultimately, it’s the end for which we were made: union with Him.
- What is the cost to Himself? He sacrifices His claim against us for sinning against Him—He shows us mercy.
By doing this, it appears that God abandons justice in favor of love. But how can He do this, if He is perfectly just? Doesn’t sin demand punishment?
Yes, sin demands punishment. But with so much sin against so perfect a God, who could possibly bear it? Who, except God Himself?
So He becomes flesh in the person of Jesus Christ, living, suffering, and dying for us—willing the good of each of us at whatever cost to Himself. God’s perfect justice demands a perfect price be paid, so He pays it Himself. His love is mercy.
In the person of Jesus Christ, God loves us to death. All that remains for us is to return the favor.
