Actus Fidei | Act of Faith 

Domine Deus, credo firmiter te esse, unum Deum in tribus Personis, Patrem, Filium et Spiritum Sanctum;
credo etiam Filium tuum factum esse hominem, passum et mortuum pro nobis, qui redditurus est unicuique secundum opera sua;
credo quoque omnia, quae credit et docet sancta Catholica et Apostolica Ecclesia, quia tu, Deus, ea omnia revelasti, qui es aeterna veritas et sapientia, quae nec fallere nec falli potest.
In hac fide vivere et mori statuo. Amen.

O Lord 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, suffered, and died for our sins, and that He shall come to judge the living and the dead.
I believe all that the Holy Catholic and Apostolic Church teaches because Thou hast revealed it, who canst neither deceive nor be deceived.
In this faith, I will live and die. Amen.
