CCC 143 By faith, man completely submits his intellect and his will to God.1 With his whole being man gives his assent to God the revealer. Sacred Scripture calls this human response to God, the author of revelation, “the obedience of faith”.2

CCC 1204 The celebration of the liturgy, therefore, should correspond to the genius and culture of the different peoples.3 In order that the mystery of Christ be “made known to all the nations. .. to bring about the obedience of faith,”4 it must be proclaimed, celebrated, and lived in all cultures in such a way that they themselves are not abolished by it, but redeemed and fulfilled:5 It is with and through their own human culture, assumed and transfigured by Christ, that the multitude of God’s children has access to the Father, in order to glorify him in the one Spirit.

CCC 2087 Our moral life has its source in faith in God who reveals his love to us. St. Paul speaks of the “obedience of faith”6 as our first obligation. He shows that “ignorance of God” is the principle and explanation of all moral deviations.7 Our duty toward God is to believe in him and to bear witness to him.

CCC 2641 “[Address] one another in psalms and hymns and spiritual songs, singing and making melody to the Lord with all your heart.”8 Like the inspired writers of the New Testament, the first Christian communities read the Book of Psalms in a new way, singing in it the mystery of Christ. In the newness of the Spirit, they also composed hymns and canticles in the light of the unheard-of event that God accomplished in his Son: his Incarnation, his death which conquered death, his Resurrection, and Ascension to the right hand of the Father.9 Doxology, the praise of God, arises from this “marvelous work” of the whole economy of salvation.10
