Have mercy on me, O God, according to your great loving kindness.
And according to the multitude of your mercies, blot out my iniquity.
Wash me yet more from my iniquity, and cleanse me from my sin.
For I acknowledge my transgression; and my sin is ever before me.
To you only have I sinned, and done evil in your sight:
That you may be justified in your words, and be vindicated when you are judged.

For behold, I was conceived in iniquities; and in sins my mother conceived me.
For behold, you have loved the truth;
The obscure and hidden elements of your wisdom you have made known to me.
You will sprinkle me, O Lord, with hyssop, and I shall be cleansed;
You will wash me, and I shall be made whiter than snow.

Then you will accept the sacrifice of the righteous,
The oblations and the whole-burnt offerings;
Then they will lay bullocks upon your altar.

Composed around 1638, Miserere mei was the most famous of twelve settings used at the Sistine Chapel since 1514. At some point, it became forbidden to transcribe the music and it was allowed to be performed only at those particular services at the Sistine Chapel. According to the popular story (backed by family letters), at fourteen years of age Mozart was visiting Rome when he first heard the piece during the Wednesday service. Later that day, he wrote it down entirely from memory, returning to the Chapel that Friday to make minor corrections. Less than three months after hearing the song and transcribing it, Mozart had gained fame for the work and was summoned back to Rome by Pope Clement XIV, who showered praise on him for his feat of musical genius and awarded him the Chivalric Order of the Golden Spur on July 4, 1770.

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 debts, as we also have forgiven our debtors.
And lead us not into temptation, but deliver us from evil. Amen!

Let my prayer arise in Thy sight as incense;
And let the lifting up of my hands be an evening sacrifice.
Lord, I call upon Thee, hear me;
Receive the voice of my prayer, when I call upon Thee.

Set a guard, O Lord, over my mouth,
And keep watch over the door of my lips.
Incline not my heart to evil words,
Nor to make excuses for my sins.

Spirit of God, fill my life, fill my soul, fill my very being.
And fill me, fill me, fill me with your presence,
Fill me, fill me with your power,
Fill me, fill me with your love.
