CIC 112 1. Be especially attentive “to the content and unity of the whole Scripture”. Different as the books which compose it may be, Scripture is a unity by reason of the unity of God’s plan, of which Christ Jesus is the center and heart, open since his Passover.1
The phrase “heart of Christ” can refer to Sacred Scripture, which makes known his heart, closed before the Passion, as the Scripture was obscure. But the Scripture has been opened since the Passion; since those who from then on have understood it, consider and discern in what way the prophecies must be interpreted.2

CIC 627 Christ’s death was a real death in that it put an end to his earthly human existence. But because of the union which the person of the Son retained with his body, his was not a mortal corpse like others, for “it was not possible for death to hold him” 3 4 and therefore “divine power preserved Christ’s body from corruption.” Both of these statements can be said of Christ: “He was cut off out of the land of the living”,5 and “My flesh will dwell in hope. For you will not abandon my soul to Hades, nor let your Holy One see corruption.”6 Jesus’ resurrection “on the third day” was the sign of this, also because bodily decay was held to begin on the fourth day after death.7

CIC 659 “So then the Lord Jesus, after he had spoken to them, was taken up into heaven, and sat down at the right hand of God.”8 Christ’s body was glorified at the moment of his Resurrection, as proved by the new and supernatural properties it subsequently and permanently enjoys.9 But during the forty days when he eats and drinks familiarly with his disciples and teaches them about the kingdom, his glory remains veiled under the appearance of ordinary humanity.10 Jesus’ final apparition ends with the irreversible entry of his humanity into divine glory, symbolized by the cloud and by heaven, where he is seated from that time forward at God’s right hand.11 Only in a wholly exceptional and unique way would Jesus show himself to Paul “as to one untimely born”, in a last apparition that established him as an apostle.12

CIC 730 At last Jesus’ hour arrives:13 he commends his spirit into the Father’s hands14 at the very moment when by his death he conquers death, so that, “raised from the dead by the glory of the Father,”15 he might immediately give the Holy Spirit by “breathing” on his disciples.16 From this hour onward, the mission of Christ and the Spirit becomes the mission of the Church: “As the Father has sent me, even so I send you.”17

CIC 981 After his Resurrection, Christ sent his apostles “so that repentance and forgiveness of sins should be preached in his name to all nations.”18 The apostles and their successors carry out this “ministry of reconciliation,” not only by announcing to men God’s forgiveness merited for us by Christ, and calling them to conversion and faith; but also by communicating to them the forgiveness of sins in Baptism, and reconciling them with God and with the Church through the power of the keys, received from Christ:19
[The Church] has received the keys of the Kingdom of heaven so that, in her, sins may be forgiven through Christ’s blood and the Holy Spirit’s action. In this Church, the soul dead through sin comes back to life in order to live with Christ, whose grace has saved us.20

CIC 1094 It is on this harmony of the two Testaments that the Paschal catechesis of the Lord is built,21 and then, that of the Apostles and the Fathers of the Church. This catechesis unveils what lay hidden under the letter of the Old Testament: the mystery of Christ. It is called “typological” because it reveals the newness of Christ on the basis of the “figures” (types) which announce him in the deeds, words, and symbols of the first covenant. By this re-reading in the Spirit of Truth, starting from Christ, the figures are unveiled.22 Thus the flood and Noah’s ark prefigured salvation by Baptism,23 as did the cloud and the crossing of the Red Sea. Water from the rock was the figure of the spiritual gifts of Christ, and manna in the desert prefigured the Eucharist, “the true bread from heaven.”24

CIC 1120 The ordained ministry or ministerial priesthood is at the service of the baptismal priesthood.25 The ordained priesthood guarantees that it really is Christ who acts in the sacraments through the Holy Spirit for the Church. The saving mission entrusted by the Father to his incarnate Son was committed to the apostles and through them to their successors: they receive the Spirit of Jesus to act in his name and in his person.26 The ordained minister is the sacramental bond that ties the liturgical action to what the apostles said and did and, through them, to the words and actions of Christ, the source and foundation of the sacraments.

CIC 1122 Christ sent his apostles so that “repentance and forgiveness of sins should be preached in his name to all nations.”27 “Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit.”28 The mission to baptize, and so the sacramental mission, is implied in the mission to evangelize, because the sacrament is prepared for by the word of God and by the faith which is assent to this word:
The People of God is formed into one in the first place by the Word of the living God. .. The preaching of the Word is required for the sacramental ministry itself, since the sacraments are sacraments of faith, drawing their origin and nourishment from the Word.29

CIC 1304 Like Baptism which it completes, Confirmation is given only once, for it too imprints on the soul an indelible spiritual mark, the “character,” which is the sign that Jesus Christ has marked a Christian with the seal of his Spirit by clothing him with power from on high so that he may be his witness.30
