Catechism Part 1, Section 2, Chapter 3, Article 8: I believe in the Holy Spirit (683-747)

Knowledge of faith is only possible by the Holy Spirit. The Holy Spirit communicates to us by virtue of our baptism, and is the first to communicate us to the new life. The Holy Spirit which is God's spirit reveals God, makes known Christ , his word and living Utterance but the Spirit does not speak of himself. The Holy Spirit, at work since the beginning of creation, is now revealed and given. Only through the Spirit does God speak to us, and the Spirit can be heard in scripture, the Tradition, the magisterium, the sacramental liturgy, prayer, charisms and ministries by which the Church is built up, signs of apostolic and missionary life, and in  the witness of saints through whom he manifests his holiness and continues the work of salvation.

I. Joint Mission of the Son and the Spirit (689-690)
The one whom the Father sent into our hearts , the Spirit of his Son, is truly God. The Spirit is inseparable from the Son and Father in the inner life of the Trinity and  his gift of love for the world. In adoring the Holy Trinity, life-giving, consubstantial,and individual the Church also professes the distinction of persons. When the Father sends his Word he always sends his Breath. The Son and the Spirit are distinct but inseparable in their joint mission. When Christ is finally glorified he can in turn send the Spirit from his place with the Father to those who believe in him to communicate his glory to them. Jesus is Christ anointed  because the Spirit is his anointing and everything that occurs from the Incarnation on derives from the fullness.

II. The Name, Titles, and Symbols of the Holy Spirit (691-701)
The Holy Spirit is the proper name of the third person of the Trinity, which translates from the Hebrew word for "breath." The titles of the Holy Spirit include consoler, the Spirit of truth, the Spirit of promise, the Spirit of adoption, the Spirit of Christ, the Spirit of the Lord, the Spirit of God, and the Spirit of glory. Symbols used to refer to the Holy Spirit include water, anointing, fire, cloud and light, the seal, the hand, the finger, and the dove.

III. God's Spirit and Word in the Time of the Promises (702-716)
In the Old Testament the Spirit spoke through the prophets about preparing for the coming Messiah and inspired those who composed the Scriptures to write them. Both the Word and his breath worked in the  creation and gave life to all living things. Disfigured by sin and death man remains in the image of God, in the image of the Son but is deprived of the glory of God of his likeness. The promise made to Abraham inaugurates the economy of salvation, at the culmination of which the Son himself will assume that image and restore it in the Father's likeness by giving it again its Glory , the Spirit who is the giver of life. God promises descendants to Abraham as the fruit of faith and of the power of the Holy Spirit. Through Abrahams family line all nations of the earth shall be blessed this is through Christ Abrahams decedent in whom the outpouring of the Holy Spirit will gather all Children of God who have been scattered. God commits himself to this promise as he gives his only Son in order for the outpouring of his Holy Spirit.   Theophanies (manifications of God) light up the way of the promise from the patriarchs to moses and from Joshua to the visions that inaugurated the missions of the great prophets. Also the gift of the Law  God gave the letter of the law as a pedagogue to lead his people towards Christ.But the law is powerless to save man deprived of the divine likeness, along with the growing awareness of sin that imparts, enkindles a desire for the Holy Spirit. The Law the sign of God's promise and covenant, ought to have governed the hearts and institutions of that people whom Abraham's faith gave birth. The Kingdom the object of promise made to David would be the work of the Holy Spirit; it would belong to the poor according to the Spirit.  The forgetting of the Law and the infidelity to the covenant end in death; it is Exile, apparently the failiure of promisises , which in fact the mysterious promised restoration, but according to the Spirit. The people of God had to suffer this purification. Prophets point both the the coming of the Messiah and the Spirit.   The people of  the poor those who are humble and meek, rely solely on their God's mysterious plans, who await justice, not of men but of the Messiah are in the end the great achievement of the Holy Spirit 's hidden mission during the time of the promises that prepare for Christ's coming. In the poor , the Spirit is making ready a people prepared for the Lord.


IV. The spirit of Christ in the Fullness of Time (717-730)

John the Baptist was full of the Holy Spirit, and through John, the Spirit prepared the people for Christ. John also brings the cycle of prophets to an end that began with Elijah , and begins restoring man to divine likeness. John is the voice of the Counsoler who is comingThe Spirit also worked through Mary to prepare for the coming of Christ, preparing her to be full of his grace. She was by, sheer grace, concieved without sin as the most humble of creatures, the most capable of welcoming the inexpressible gift of the Almighty. In Mary the Holy Spirit fulfills the plan of the Father's loving goodness. Filled with the Holy spirit she makes the Word visable in the humility of his flesh. It is to the poor and first represenatives of the gentiles that she makes him known. Mary became the Women , the new Eve(mother of the living) the mother of the whole Christ. Mary the all holy ever virgin Mother of God, is the masterwork of the mission of the Son and the Spirit in the fullness of time. Mary is acclaimed and represented in the liturgy as the Seat of Wisdom.  Mary conceived through the Spirit, who manifested in her the Son, and began to bring men into communion with Christ. Christ Jesus was anointed by the Spirit, and though he did not reveal the Spirit fully before his resurrection, he alluded to the Spirit. When Jesus was glorified, the Spirit was sent from the Father and the Son. Now the mission of the Son and the Spirit becomgreaes the mission of the Church.

V. The Spirit and the Church in the Last Days (731-741)
On Pentecost, the Spirit was outpoured and the Trinity fully revealed. Since that day , the Kingdom announced by Christ has been open to those who believe in him: in the humility of the flesh and in faith, they already share in the communion of the Holy Trinity. By his coming the Holy Spirit causes the world to enter into the last days. Love is God's first gift to us through the Spirit as God is love. The first effect is the forgiveness of sins, and loving as God loves us becomes possible. Through this power, we can bear the Fruits of the Spirit. The Church completes the mission of the Son and the Spirit, not as an addition but as a sacrament. Christ pours out the Spirit to all the members of the Church through the sacraments, which bear fruit in the life in Christ.Christ pours out his Spirit among the Church to nourish, heal, and organize them in their mutual functions, to give them life, send them to bear witness, and associate them to his self-offering to the Father and to his intercession for the whole world. Finally, the Spirit is the master of prayer as he intercedes for us with the Father.
