Act of Faith (Prayer)

O my God, I firmly believe that Thou art one God, in three Divine Persons, the Father, the Son and the Holy Ghost; I believe that Thy 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 Thou hast revealed them, Who canst neither deceive nor be deceived. Amen.
