Part 1, Section 2, Chapter 1, Article 1, Paragraph 2, SubSection 2, Heading 2

244 The eternal origin of the Holy Spirit is revealed in his mission in time. The Spirit is sent to the apostles and to the Church both by the Father in the name of the Son, and by the Son in person, once he had returned to the Father. 69 The sending of the person of the Spirit after Jesus' glorification 70 reveals in its fullness the mystery of the Holy Trinity.

Part 1, Section 2, Chapter 1, Article 1, Paragraph 2, SubSection 2, Heading 2

248 At the outset the Eastern tradition expresses the Father's character as first origin of the Spirit. By confessing the Spirit as he "who proceeds from the Father", it affirms that he comes from the Father through the Son. 77 The Western tradition expresses first the consubstantial communion between Father and Son, by saying that the Spirit proceeds from the Father and the Son (filioque). It says this, "legitimately and with good reason", 78 for the eternal order of the divine persons in their consubstantial communion implies that the Father, as "the principle without principle", 79 is the first origin of the Spirit, but also that as Father of the only Son, he is, with the Son, the single principle from which the Holy Spirit proceeds. 80 This legitimate complementarity, provided it does not become rigid, does not affect the identity of faith in the reality of the same mystery confessed.

Part 1, Section 2, Chapter 1, Article 1, Paragraph 2, SubSection 4

263 The mission of the Holy Spirit, sent by the Father in the name of the Son (Jn 14:26) and by the Son "from the Father" (Jn 15:26), reveals that, with them, the Spirit is one and the same God. "With the Father and the Son he is worshipped and glorified" (Nicene Creed).

530 The flight into Egypt and the massacre of the innocents 217 make manifest the opposition of darkness to the light: "He came to his own home, and his own people received him not." 218 Christ's whole life was lived under the sign of persecution. His own share it with him. 219 Jesus' departure from Egypt recalls the exodus and presents him as the definitive liberator of God's people. 220

Part 1, Section 2, Chapter 2, Article 7, SubSection 1, Heading 4

675 Before Christ's second coming the Church must pass through a final trial that will shake the faith of many believers. 573 The persecution that accompanies her pilgrimage on earth 574 will unveil the "mystery of iniquity" in the form of a religious deception offering men an apparent solution to their problems at the price of apostasy from the truth. The supreme religious deception is that of the Antichrist, a pseudo-messianism by which man glorifies himself in place of God and of his Messiah come in the flesh. 575

692 When he proclaims and promises the coming of the Holy Spirit, Jesus calls him the "Paraclete," literally, "he who is called to one's side," ad-vocatus. 18 "Paraclete" is commonly translated by "consoler," and Jesus is the first consoler. 19 The Lord also called the Holy Spirit "the Spirit of truth." 20

719 John the Baptist is "more than a prophet." 94 In him, the Holy Spirit concludes his speaking through the prophets. John completes the cycle of prophets begun by Elijah. 95 He proclaims the imminence of the consolation of Israel; he is the "voice" of the Consoler who is coming. 96 As the Spirit of truth will also do, John "came to bear witness to the light." 97 In John's sight, the Spirit thus brings to completion the careful search of the prophets and fulfills the longing of the angels. 98 "He on whom you see the Spirit descend and remain, this is he who baptizes with the Holy Spirit. And I have seen and have borne witness that this is the Son of God.... Behold, the Lamb of God." 99

729 Only when the hour has arrived for his glorification does Jesus promise the coming of the Holy Spirit, since his Death and Resurrection will fulfill the promise made to the fathers. 116 The Spirit of truth, the other Paraclete, will be given by the Father in answer to Jesus' prayer; he will be sent by the Father in Jesus' name; and Jesus will send him from the Father's side, since he comes from the Father. The Holy Spirit will come and we shall know him; he will be with us for ever; he will remain with us. The Spirit will teach us everything, remind us of all that Christ said to us and bear witness to him. The Holy Spirit will lead us into all truth and will glorify Christ. He will prove the world wrong about sin, righteousness, and judgment.

Part 1, Section 2, Chapter 3, Article 9, Paragraph 1, SubSection 2, Heading 4

765 The Lord Jesus endowed his community with a structure that will remain until the Kingdom is fully achieved. Before all else there is the choice of the Twelve with Peter as their head. 168 Representing the twelve tribes of Israel, they are the foundation stones of the new Jerusalem. 169 The Twelve and the other disciples share in Christ's mission and his power, but also in his lot. 170 By all his actions, Christ prepares and builds his Church.

Part 2, Section 2, Chapter 2, Article 4, SubSection 4

1433 Since Easter, the Holy Spirit has proved "the world wrong about sin," 29 i.e., proved that the world has not believed in him whom the Father has sent. But this same Spirit who brings sin to light is also the Consoler who gives the human heart grace for repentance and conversion. 30

Part 4, Section 1, Chapter 2, Article 2, Heading 3

2671 The traditional form of petition to the Holy Spirit is to invoke the Father through Christ our Lord to give us the Consoler Spirit. 23 Jesus insists on this petition to be made in his name at the very moment when he promises the gift of the Spirit of Truth. 24 But the simplest and most direct prayer is also traditional, "Come, Holy Spirit," and every liturgical tradition has developed it in antiphons and hymns.

Come, Holy Spirit, fill the hearts of your faithful and enkindle in them the fire of your love. 25

Heavenly King, Consoler Spirit, Spirit of Truth, present everywhere and filling all things, treasure of all good and source of all life, come dwell in us, cleanse and save us, you who are All Good. 26
