"Act of Faith" Prayer

On one or two occasions when flipping past a (Roman) Catholic TV station or looking into a church, I've run across a prayer known as the "Act of Faith" or "Act of Faith Prayer."  There is nothing at all in the content that a Reformational Christian who can affirm the Apostles' Creed would find objectionable.

In fact, I'm not too sure why this Act of Faith developed, since everything in it is basically already found in the Apostles' Creed and certainly in the more comprehensive Nicene Creed (though the Creeds affirm some other things not found here, as this Act of Faith is actually even shorter than the Apostles' Creed).  But as a short confession of faith in the form of a prayer, it is impressive.

Maybe Methodists, Anglicans, Lutherans and other "Reformed catholic" Christians would profit from using this prayer devotionally.

 O my God, I firmly believe that you are one God in three divine Persons, Father, Son, and Holy Spirit. I believe that your 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 you have revealed them, who can neither deceive nor be deceived. Amen.
