This is the Prayer Book, a collection of my favorite Catholic Prayers.

Most basic introductional Catholic Prayers: Sign of The Cross, Our Father, Hail Mary, Glory Be, Oh My Jesus, Apostles Creed

Sign of the Cross: (While doing this prayer you cross yourself before every prayer and after every prayer) In the name of the Father, and of the Son, and of the Holy Spirit. Amen.

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; the third day he rose again from the dead; he ascended into heaven and is seated at the right hand of the Father; from thence he shall 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.

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.

Hail Mary: Hail Mary, Full of Grace, The Lord is with Thee. Blessed art thou amongst women and blessed is thy fruit of thy womb, Jesus. Holy Mary, Mother of God, Pray for us sinners, now and at the hour of our death. Amen.

Oh My Jesus: Oh My Jesus, Forgive us our sins. Save us from the fires of Hell. Lead all souls to Heaven, especially those most need of thy mercy. Amen.
