Rosaire de Miséricorde Divine

This third was taught during a vision that Sister Faustina had on September 13, 1935: “I saw an angel, the executioner of the wrath of God, at the point of reaching the earth. I began to cry out to God for the world with words I heard inside. Praying like this, I saw that the angel was abandoned, and he could no longer carry out punishment.

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

"In reciting this rosary, I am pleased to give all that is required of Me. When they recite hardened sinners, I will fill their souls with peace, and their hour of death will be happy. Write this to the troubled ages: when the The soul sees and recognizes the gravity of its sins, when the whole abyss of misery into which it has plunged has been revealed, let it not despair, but let it throw itself with confidence into the arms of my mercy . Like a child in the arms of His dear mother. These souls have a right of precedence over My merciful heart. Say that no soul who has turned to My mercy has been disappointed or shown vexation.

“When they pray this rosary with the dying, I will be between the Father and the soul who dies, not as a just judge, but as a merciful Savior.”

The rosary also includes the contemplation of certain passages in the life of Jesus and his mother Mary which, according to the doctrine of the Catholic Church, are of particular importance for 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.
