Prayers are presented here in multiple forms, including Latin for some, and with or without the 2nd person "thy/thine" form of "you/your"

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

"From Our Father (USCCB)

Pater noster, qui es in cælis:
sanctificétur nomen tuum;
advéniat regnum tuum;
fiat volúntas tua,sicut in cælo, et in terra.
Panem nostrum cotidiánum da nobis hódie;
et dimítte nobis débita nostra,
sicut et nos dimíttimus debitóribus nostris;
et ne nos indúcas in tentatiónem;
sed líbera nos a malo.
Amen.

From the Roman Missal 2002

    • whereas the Catholic Church generally refers to it as the "Our Father"
  • See Lord's Prayer for Scriptural source of the "Our Father" in Mathew and Luke

In 1106, European Crusaders built a chapel in the ruins of the "Church of the Disciples," built by St. Helena (mother of Constantine) in the early 300s AD over a cave on the Mount of Olives thought to be the location of the Ascension of Christ. The Crusaders associated the site with the teaching of the Our Father prayer. The entire site was excavated and a new church and compound built that preserves part of the original churches, as well as the chapel area, a grotto, where the Crusaders thought that Jesus taught the Our Father prayer.

Prayer to Jesus

also, "The Prayer," or "The Jesus Prayer"

Lord Jesus Christ, Son of God, have mercy on me a sinner

or

Lord Jesus Christ, Son of the Living God, have mercy on me a sinner
Domine Jesu Christe, Fili Dei,

miserere mei, peccatoris

Notes:

  • in the early Church, the Jesus Prayer was used as a repetitive prayer, as one would the "Hail Mary"
  • the Prayer is traditionally linked to breathing, thus it was meditative
  • see The Jesus Prayer (holyrosary.com.au)
  • see CCC 2665-2669
    • click EXPAND for CCC 2666:

But the one name that contains everything is the one that the Son of God received in his incarnation: JESUS. The divine name may not be spoken by human lips, but by assuming our humanity The Word of God hands it over to us and we can invoke it: "Jesus," "YHWH saves." The name "Jesus" contains all: God and man and the whole economy of creation and salvation. To pray "Jesus" is to invoke him and to call him within us. His name is the only one that contains the presence it signifies. Jesus is the Risen One, and whoever invokes the name of Jesus is welcoming the Son of God who loved him and who gave himself up for him. (CCC 2666)

Saint Michael the Archangel

also, "Prayer to Saint Michael"

St. Michael the Archangel,

defend us in battle;

be our defense 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 power of God,

cast into hell Satan

and all the evil spirits

who prowl about the world,

seeking the ruin of souls.

Amen.

Sancte Michael Archangele,

Defende nos in proelio,

contra nequitiam et insidias

diaboli esto praesidium.

Imperet illi Deus, supplices deprecamur:

tuque,

Princeps militiae caelestis,

in virtute Dei,

in infernum detrude satanam

aliosque spiritus malignos,

qui ad perditionem animarum

pervagantur in mundo.

Amen.

 
Notes:
  • The prayer was composed by Pople Leo XIII in 1880 or 1884 after experiencing at the end of Mass a vision of demonic spirits descending upon Rome.
  • the prayer is traditionally recited after Mass up to 1964, when Inter oecumenici removed it as an obligation.
