1.From the first centuries to the present day, the Church has professed the truths of her faith in Christ and the mystery of his redemption. These truths were subsequently gathered into the Symbols of the faith, today known and proclaimed in common by the faithful in the solemn and festive celebration of Mass as the Apostles’ Creed or the Nicene-Constantinopolitan Creed.

This same Nicene-Constantinopolitan Creed is contained in the Profession of faith developed by the Congregation for the Doctrine of the Faith,(¹) which must be made by specific members of the faithful when they receive an office, that is directly or indirectly related to deeper investigation into the truths of faith and morals, or is united to a particular power in the governance of the Church.(²)
