1. IN THE NAME of the Father, and the Son, and of the Holy Spirit.
So be it, truly.
I BELIEVE in one God, the Father, the 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, [bow]
and by the the Holy Spirit he was incarnate of the Virgin Mary,
AND BECAME MAN. [raise from bow] 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 he 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.
So be it, truly.
O GOD, come to my assistance; O Lord, make haste to help me.
GLORY BE TO THE FATHER, and to the Son, and to the Holy
Spirit. As it was in the beginning, is now, and ever shall be.
So be it, truly.
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.
So be it, truly.
HAIL, MARY, full of grace! The Lord is with thee; blessed art
thou among women, and blessed is the fruit of thy womb, Jesus.
Holy Mary, Mother of God, pray for us sinners now and at the time
of our death.
So be it, truly.
O MY JESUS, forgive us our sins, save us from the fires of hell,
lead all souls to Heaven, especially those in most need of Thy
mercy.
So be it, truly.

2. O MARY conceived without sin, pray for us who have recourse to
Thee.
SAINT Michael the Archangel, defend us in battle.
Be our protection against the wickedness and snares of the devil.
May God rebuke him, we humbly pray; and do Thou, O Prince of
the Heavenly Host “by the Divine Power of God” cast into hell,
Satan and all the evil spirits, who roam throughout the world
seeking the ruin of souls.
So be it, truly.
REMEMBER, O most gracious Virgin Mary, that never was it
known that anyone who fled to your protection, implored your help
or sought your intercession was left unaided. Inspired with this
confidence, I fly to you, O Virgin of virgins, my Mother; to you do
I come, before you I stand, sinful and sorrowful. O Mother of the
Word Incarnate, despise not my petitions, but in your mercy hear
and answer me.
So be it, truly.
HAIL, HOLY QUEEN, Mother of mercy, hail, our life, our
sweetness, and our hope! To you do we cry, poor banished children
of Eve! To you do we send up our sighs, mourning, and weeping in
this vale of tears! Turn then, most gracious advocate, your eyes of
mercy toward us; and after this, our exile, show unto us the blessed
fruit of your womb, Jesus! O clement, O loving, O sweet Virgin
Mary. Pray for us Holy Mother of God, that we may become
worthy of the promises of Jesus-Christ.
O MARIA, sine labe origináli concépta ora pro nobis,
qui confugímus ad te.
SANCTE Michael Archangele, defende nos in prœlio;
contra nequitiam et insidias diaboli esto præsidium.
Imperet illi Deus, supplices deprecamur : tuque, Princeps
militiæ cælestis, Satanam aliosque spiritus malignos, qui
ad perditionem animarum pervagantur in mundo, divina
virtute in infernum detrude.
Amen.
MEMORARE / REMEMBER
MEMORARE, o piisima Virgo Maria, non esse auditum
a sæculo, quemquam ad tua currentem præsidia, tua
implorantem auxilia, tua petentem suffragia esse
derelicta. Nos tali animati confidentia ad te, Virgo
Virginum, Mater, currimus; ad te venimus; coram te
gementes peccatores assistimus. Noli, Mater Verbi, verba
nostra despicere, sed audi propitia et exaudi.
Amen.
SALVE REGINA / HAIL, HOLY QUEEN
SALVE, REGINA, mater misericórdiæ, vita, dulcédo, et
spes nostra, salve. Ad te clamámus éxsules filii Hevæ ;
Ad te suspirámus, geméntes et flentes in hac lacrymárum
valle. Eia, ergo, advocáta nostra, illos tuos misericórdes
óculos ad nos convérte. Et Jesum, benedictum fructum
ventris tui, nobis post hoc exílium osténde. O clemens, o
pia, o dulcis Virgo Maria. Ora pro nobis, sancta Dei
Génetrix. Ut digni efficiámur promissiónibus Christi.
