The Apostles' Creed (Credo)
I believe in God, the Father Almighty, Creator of heaven and earth.
I believe in Jesus Christ, his only Son, our Lord.
He was conceived by the power of the Holy Spirit and born of the Virgin Mary.
He suffered under Pontius Pilate, was crucified, died, and was buried.
He descended to the dead.
On the third day he rose again.
He ascended into Heaven, and is seated at the right hand of the Father.
He will come again 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.

Hail Mary (Ave-Maria)
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 hour of our death.
Amen!

Our Father (Pai Nosso)
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 our trespasses
as we forgive those who trespass against us;
and lead us not into temptation, but deliver us from evil.
Amen.

Guardian Angel Prayer (Oração do Anjo da Guarda)
Angel of God, my Guardian Dear, to whom God's love commits me here.
Ever this day be at my side, to light and guard and rule and guide.
Amen
