Our Father who art in heaven,
hallowed be thy name;
thy kingdom come.
thy will be done

as we forgive those who trespass against us;
and lead us not into temptation,
but deliver us from evil.  Amen.

Prayer to One’s Guardian Angel
Angel of God, my guardian dear,

Nicene Creed
I believe in one God,
the Father almighty,
maker of heaven and earth,
of all things visible and invisible.

I believe in one Lord Jesus Christ,
the Only Begotten Son of God,
born of the Father before all ages.
God from God, Light from Light,
true God from true God,
begotten, not made, consubstantial with the Father;
through him all things were made.
For us men and for our salvation
he came down from heaven,
and by the Holy Spirit was incarnate of the Virgin Mary,
and became man.
For our sake he was crucified under Pontius Pilate,
he suffered death and was buried,
and rose again on the third day
in accordance with the Scriptures.
He ascended into heaven
and is seated at the right hand of the Father.
He will come again in glory
to judge the living and the dead
and his kingdom will have no end.

I believe in the Holy Spirit, the Lord, the giver of life,
who proceeds from the Father and the Son,
who with the Father and the Son is adored and glorified,
who has spoken through the prophets.

I believe in one, holy, catholic and apostolic Church.
I confess one Baptism for the forgiveness of sins
and I look forward to the resurrection of the dead
and the life of the world to come.  Amen.

Apostle’s 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.

Act of Contrition
O my God, I am heartily sorry for having offended Thee, and I detest all my sins because of thy just punishments, but most of all because they offend Thee, my God, who art all good and deserving of all my love. I firmly resolve with the help of Thy grace to sin no more and to avoid the near occasion of sin. Amen.
(A traditional version)

or:

My God,
I am sorry for my sins with all my heart.
In choosing to do wrong
and failing to do good,
I have sinned against you
whom I should love above all things.
I firmly intend, with your help,
to do penance,
to sin no more,
and to avoid whatever leads me to sin.
Our Savior Jesus Christ suffered and died for us.
In his name, my God, have mercy.
(from the Rite of Penance)

Lord Jesus, Son of God,
have mercy on me, a sinner.
(from the Rite of Penance)

I believe that your divine Son became man and died for our sins and that he will come to judge the living and the dead. I believe these and all the truths which the Holy Catholic Church teaches because you have revealed them who are eternal truth and wisdom, who can neither deceive nor be deceived. In this faith I intend to live and die. Amen

Soul of Christ, be my sanctification.
Body of Christ, be my salvation.
Blood of Christ, fill all my veins.
Water of Christ’s side, wash out my stains.

Hail, Holy Queen (The Salve Regina)
Hail, Holy Queen, Mother of Mercy,
our life, our sweetness and our hope.
To thee do we cry,
poor banished children of Eve.
To thee do we send up our sighs,
mourning and weeping in this valley of tears.
Turn then, most gracious advocate,
thine eyes of mercy toward us,
and after this our exile
show unto us the blessed fruit of thy womb, Jesus.
O clement, O loving,
O sweet Virgin Mary.

Memorare
Remember, O most gracious Virgin Mary, that never was it known that anyone who fled to thy protection, implored thy help, or sought thy intercession, was left unaided. Inspired by this confidence I fly unto thee, O Virgin of virgins, my Mother. To thee do I come, before thee I stand, sinful and sorrowful. O Mother of the Word Incarnate, despise not my petitions, but in thy mercy hear and answer me. Amen.

Morning Offering
O Jesus, through the Immaculate Heart of Mary,
I offer you my prayers, works, joys and sufferings of this day

in union with the Holy Sacrifice of the Mass throughout the world,
for the salvation of souls, the reparation for sins, the reunion of all Christians,
and in particular for the intentions of the Holy Father this month.  Amen.

Tantum Ergo
Down in adoration falling,
Lo! the sacred Host we hail;
Lo! o’er ancient forms departing,
Newer rites of grace prevail;
Faith for all defects supplying,
Where the feeble senses fail.
To the everlasting Father,
And the Son who reigns on high,
With the Holy Spirit proceeding
Forth from each eternally,
Be salvation, honor, blessing,
Might and endless majesty. Amen.
V. You have given them bread from heaven,
R. Having all delight within it.
Let us pray.
O God, who in this wonderful Sacrament
left us a memorial of your Passion:
grant, we implore you,
that we may so venerate
the sacred mysteries of your Body and Blood,
as always to be conscious of the fruit of your Redemption.
You who live and reign forever and ever. Amen.
