The Rosary of Mercy with audio and offline to listen at the time of Mercy

This third was taught during a vision that Sister Faustina had on September 13, 1935: “I saw an angel, the executor of the wrath of God, so as to strike the earth. I started imploring God for the world with words that I heard inside. As I prayed like this, I saw that the angel was forsaken, and he could no longer carry out the just punishment.

The next day, an inner voice taught him this prayer in the rosaries.

"By reciting this rosary, it pleases me to give all that is asked of me. When hardened sinners recite it, I will fill their souls with peace, and their hour of death will be happy. Writing for troubled souls: When the soul sees and recognizes the gravity of their sins, when it unravels before your eyes all the abyss of misery in which dove, do not despair, but if the offer with confidence in the arms of my mercy, like a child in the dear mother's arm. These souls have precedence over My merciful heart. Say that no soul who has turned to My mercy has been disappointed or vexed."

"When they pray this rosary with the dying, I will place myself between the Father and the dying soul, not as a just judge, but as a merciful Saviour."

The rosary also includes the contemplation of certain passages from the life of Jesus and his mother Mary, which, according to the doctrine of the Catholic Church, are particularly relevant to the history of salvation and are called "mysteries".

The rosary was traditionally divided into three equal parts, with fifty beads each, and which, because they corresponded to the third part, were called the rosary.
