What is Mercy?
St. Thomas Aquinas defined the virtue of "mercy" in his great Summa Theologiae (ST II-II.30.1) as "the compassion in our hearts for another person's misery, a compassion which drives us to do what we can to help him."
It is the Mercy of God, this compassion in His heart for our misery, which extends with Divine power to us, to heal us in our wounded and sinful state.
Devotion to the Mercy of God is devotion to the healing power of the Cross. The Blood and Water which poured forth as a fount for poor sinners is Christ's gift of Himself to all those who will accept His Love and be restored by the power of His Grace.
The Divine Mercy Chaplet - A Prayer for Our Times
The Divine Mercy Chaplet is a powerful devotion given by our Lord to St. Faustina Kowalska in the early 20th century.
This devotion is a profound prayer of reparation that begs the grace of conversion and offers the sacrifice of Christ's own Passion for the sake of sinful mankind.
Our Lord told St. Faustina, "The souls that say this chaplet will be embraced by My mercy during their lifetime and especially at the hour of their death.”
