CIC 158 “Faith seeks understanding”:1 it is intrinsic to faith that a believer desires to know better the One in whom he has put his faith, and to understand better what He has revealed; a more penetrating knowledge will in turn call forth a greater faith, increasingly set afire by love. The grace of faith opens “the eyes of your hearts”2 to a lively understanding of the contents of Revelation: that is, of the totality of God’s plan and the mysteries of faith, of their connection with each other and with Christ, the center of the revealed mystery. “The same Holy Spirit constantly perfects faith by his gifts, so that Revelation may be more and more profoundly understood.”3 In the words of St. Augustine, “I believe, in order to understand; and I understand, the better to believe.”4
CIC 272 Faith in God the Father Almighty can be put to the test by the experience of evil and suffering. God can sometimes seem to be absent and incapable of stopping evil. But in the most mysterious way God the Father has revealed his almighty power in the voluntary humiliation and Resurrection of his Son, by which he conquered evil. Christ crucified is thus “the power of God and the wisdom of God. For the foolishness of God is wiser than men, and the weakness of God is stronger than men.”5 It is in Christ’s Resurrection and exaltation that the Father has shown forth “the immeasurable greatness of his power in us who believe”.6
CIC 648 Christ’s Resurrection is an object of faith in that it is a transcendent intervention of God himself in creation and history. In it the three divine persons act together as one, and manifest their own proper characteristics. The Father’s power “raised up” Christ his Son and by doing so perfectly introduced his Son’s humanity, including his body, into the Trinity. Jesus is conclusively revealed as “Son of God in power according to the Spirit of holiness by his Resurrection from the dead”.7 St. Paul insists on the manifestation of God’s power8 through the working of the Spirit who gave life to Jesus’ dead humanity and called it to the glorious state of Lordship.
CIC 668 “Christ died and lived again, that he might be Lord both of the dead and of the living.”9 Christ’s Ascension into heaven signifies his participation, in his humanity, in God’s power and authority. Jesus Christ is Lord: he possesses all power in heaven and on earth. He is “far above all rule and authority and power and dominion”, for the Father “has put all things under his feet.”10 Christ is Lord of the cosmos and of history. In him human history and indeed all creation are “set forth” and transcendently fulfilled.11
CIC 669 As Lord, Christ is also head of the Church, which is his Body.12 Taken up to heaven and glorified after he had thus fully accomplished his mission, Christ dwells on earth in his Church. The redemption is the source of the authority that Christ, by virtue of the Holy Spirit, exercises over the Church. “The kingdom of Christ [is] already present in mystery”, “on earth, the seed and the beginning of the kingdom”.13
CIC 753 In Scripture, we find a host of interrelated images and figures through which Revelation speaks of the inexhaustible mystery of the Church. The images taken from the Old Testament are variations on a profound theme: the People of God. In the New Testament, all these images find a new center because Christ has become the head of this people, which henceforth is his Body.14 Around this center are grouped images taken “from the life of the shepherd or from cultivation of the land, from the art of building or from family life and marriage.”15
CIC 830 The word “catholic” means “universal,” in the sense of “according to the totality” or “in keeping with the whole.” The Church is catholic in a double sense:
First, the Church is catholic because Christ is present in her. “Where there is Christ Jesus, there is the Catholic Church.”16 In her subsists the fullness of Christ’s body united with its head; this implies that she receives from him “the fullness of the means of salvation”17 which he has willed: correct and complete confession of faith, full sacramental life, and ordained ministry in apostolic succession. The Church was, in this fundamental sense, catholic on the day of Pentecost18 and will always be so until the day of the Parousia.
CIC 2045 Because they are members of the Body whose Head is Christ,19 Christians contribute to building up the Church by the constancy of their convictions and their moral lives. The Church increases, grows, and develops through the holiness of her faithful, until “we all attain to the unity of the faith and of the knowledge of the Son of God, to mature manhood, to the measure of the stature of the fullness of Christ.”20
CIC 2632 Christian petition is centered on the desire and search for the Kingdom to come, in keeping with the teaching of Christ.21 There is a hierarchy in these petitions: we pray first for the Kingdom, then for what is necessary to welcome it and cooperate with its coming. This collaboration with the mission of Christ and the Holy Spirit, which is now that of the Church, is the object of the prayer of the apostolic community.22 It is the prayer of Paul, the apostle par excellence, which reveals to us how the divine solicitude for all the churches ought to inspire Christian prayer.23 By prayer every baptized person works for the coming of the Kingdom.
