CCC 14 Those who belong to Christ through faith and Baptism must confess their baptismal faith before men.1 First therefore the Catechism expounds revelation, by which God addresses and gives himself to man, and the faith by which man responds to God (Section One). The profession of faith summarizes the gifts that God gives man: as the Author of all that is good; as Redeemer; and as Sanctifier. It develops these in the three chapters on our baptismal faith in the one God: the almighty Father, the Creator; his Son Jesus Christ, our Lord and Savior; and the Holy Spirit, the Sanctifier, in the Holy Church (Section Two).

CCC 186 From the beginning, the apostolic Church expressed and handed on her faith in brief formula normative for all.2 But already very early on, the Church also wanted to gather the essential elements of her faith into organic and articulated summaries, intended especially for candidates for Baptism:
This synthesis of faith was not made to accord with human opinions, but rather what was of the greatest importance was gathered from all the Scriptures, to present the one teaching of the faith in its entirety. And just as the mustard seed contains a great number of branches in a tiny grain, so too this summary of faith encompassed in a few words the whole knowledge of the true religion contained in the Old and the New Testaments.3

CCC 432 The name “Jesus” signifies that the very name of God is present in the person of his Son, made man for the universal and definitive redemption from sins. It is the divine name that alone brings salvation, and henceforth all can invoke his name, for Jesus united himself to all men through his Incarnation,4 so that “there is no other name under heaven given among men by which we must be saved.”5

CCC 449 By attributing to Jesus the divine title “Lord”, the first confessions of the Church’s faith affirm from the beginning that the power, honor and glory due to God the Father are due also to Jesus, because “he was in the form of God”,6 and the Father manifested the sovereignty of Jesus by raising him from the dead and exalting him into his glory.7

CCC 2666 But the one name that contains everything is the one that the Son of God received in his incarnation: JESUS. The divine name may not be spoken by human lips, but by assuming our humanity The Word of God hands it over to us and we can invoke it: “Jesus,” “YHWH saves.”8 The name “Jesus” contains all: God and man and the whole economy of creation and salvation. To pray “Jesus” is to invoke him and to call him within us. His name is the only one that contains the presence it signifies. Jesus is the Risen One, and whoever invokes the name of Jesus is welcoming the Son of God who loved him and who gave himself up for him.9

CCC 2739 For St. Paul, this trust is bold, founded on the prayer of the Spirit in us and on the faithful love of the Father who has given us his only Son.10 Transformation of the praying heart is the first response to our petition.
