Also known as: My God, I firmly believe · Actus Fidei

O my God, I firmly believe all the truths that the Holy Catholic Church believes and teaches, because Thou hast revealed them, Who canst neither deceive nor be deceived. In this faith I intend to live and die. Amen.

When to pray

It is customarily prayed daily, especially during morning or night prayers, or during moments of examination of conscience.

Latin text

Deus meus, firma fide credo et confiteor omnia et singula quae sancta catholica Romana Ecclesia credit, proponit et docet, quia Tu, Deus, es prima Veritas et infallibilis, qui nec falli nec fallere potes. In hac fide vivere et mori statuo. Amen.

Origin

The Act of Faith is a traditional Catholic prayer expressing belief in God and all that He has revealed through the Church. It is one of the four principal "Acts" (Faith, Hope, Charity, and Contrition) that summarize the theological virtues and repentance. While not attributed to a single author, these prayers developed over centuries as common expressions of piety and catechesis, often recited daily or in preparation for sacraments. They serve as a foundational declaration of one's adherence to Catholic doctrine.
