Actus Fidei -- Act of Faith -- in English and Latin.
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 are eternal truth and wisdom,
who can neither deceive nor be deceived.
In this faith I intend to live and die.
firma fide credo et confíteor
ómnia et síngula quæ
sancta Ecclésia Cathólica propónit,
quia tu, Deus, ea ómnia revelásti,
qui es ætérna véritas et sapiéntia
quæ nec fállere nec falli potest.
In hac fide vívere et mori státuo.
