The Chaplet of Mercy is recited with Rosary beads and prayers from the Diary of Saint Faustina. The Chaplet begins with the Sign of the Cross, the Our Father, the Hail Mary, and the Apostles’ Creed, followed by the Eternal Father:
Eternal Father, I offer you the Body and Blood, Soul and Divinity of Your Beloved Son, Our Lord, Jesus Christ, in atonement for our sins and those of the whole world.
On each bead of each decade of the Rosary, pray:
For the sake of His sorrowful Passion, have mercy on us and on the whole world.
For each remaining decade, repeat the:
Eternal Father (on the Our Father bead of the Rosary decade), and
10 For the sake of His sorrowful Passion prayers (on the Hail Mary beads of the Rosary decade).
The Chaplet concludes with Holy God, repeated three times:
Holy God, Holy Mighty One, Holy Immortal One, have mercy on us and on the whole world.
