1) In the name of the Father, and of the Son, and of the Holy Spirit. Amen.

2) Opening Prayers (optional)

(Diary of St. Faustina Kowalska, 1319)

You expired, Jesus, but the source of life gushed forth for souls,

and the ocean of mercy opened up for the whole world.

O Fount of Life, unfathomable Divine Mercy,

envelop the whole world and empty yourself out upon us.

Repeat three times:

(Diary, 84)

O Blood and Water, which gushed forth from the Heart of Jesus as a fountain of Mercy for us, I trust in you!

3) Our Father

Our Father, who art in heaven,

hallowed be thy name;

thy kingdom come,

thy will be done

on earth as it is in heaven.

Give us this day our daily bread,

and forgive us our trespasses,

as we forgive those who trespass against us;

and lead us not into temptation,

but deliver us from evil.

Amen

4) Hail Mary

Hail, Mary, full of grace, the Lord is with you;

blessed are you among women,

and blessed is the fruit of your womb, Jesus.

Holy Mary, Mother of God,

pray for us sinners

now and at the hour of our death.

Amen.

5) The Apostles' Creed

I believe in God,

the Father almighty,

Creator of heaven and earth,

and in Jesus Christ, his only Son, our Lord,

who was conceived by the Holy Spirit,

born of the Virgin Mary,

suffered under Pontius Pilate,

was crucified, died and was buried;

he descended into hell;

on the third day he rose again from the dead;

he ascended into heaven,

and is seated at the right hand of God the Father almighty;

from there he will come to judge the living and the dead.

I believe in the Holy Spirit,

the holy catholic Church,

the communion of saints,

the forgiveness of sins,

the resurrection of the body,

and life everlasting.

Amen.

On each "Our Father" bead of the rosary, pray:

Conclusion

9) Repeat three times:

Holy God, Holy Mighty One, Holy Immortal One, have mercy on us and on the whole world.

10) Closing Prayer (optional)

(Diary, 950)

Eternal God, in whom mercy is endless and the treasury of compassion inexhaustible, look kindly upon us and increase your mercy in us, that in difficult moments we might not despair nor become despondent, but with great confidence submit ourselves to your holy will, which is Love and Mercy itself. Amen.

Or:

(Roman Missal, Votive Mass of the Mercy of God)

O God, whose mercies are without number and whose treasure of goodness is infinite, graciously increase the faith of the people consecrated to you, that all may grasp and rightly understand by whose love they have been created, through whose Blood they have been redeemed, and by whose Spirit they have been reborn. Through Christ our Lord. Amen.
