CIC 75 “Christ the Lord, in whom the entire Revelation of the most high God is summed up, commanded the apostles to preach the Gospel, which had been promised beforehand by the prophets, and which he fulfilled in his own person and promulgated with his own lips. In preaching the Gospel, they were to communicate the gifts of God to all men. This Gospel was to be the source of all saving truth and moral discipline.”1

CIC 643 Given all these testimonies, Christ’s Resurrection cannot be interpreted as something outside the physical order, and it is impossible not to acknowledge it as an historical fact. It is clear from the facts that the disciples’ faith was drastically put to the test by their master’s Passion and death on the cross, which he had foretold.2 The shock provoked by the Passion was so great that at least some of the disciples did not at once believe in the news of the Resurrection. Far from showing us a community seized by a mystical exaltation, the Gospels present us with disciples demoralized (“looking sad”3) and frightened. For they had not believed the holy women returning from the tomb and had regarded their words as an “idle tale”.4 When Jesus reveals himself to the Eleven on Easter evening, “he upbraided them for their unbelief and hardness of heart, because they had not believed those who saw him after he had risen.”5

CIC 645 By means of touch and the sharing of a meal, the risen Jesus establishes direct contact with his disciples. He invites them in this way to recognize that he is not a ghost and above all to verify that the risen body in which he appears to them is the same body that had been tortured and crucified, for it still bears the traces of his Passion.6 Yet at the same time this authentic, real body possesses the new properties of a glorious body: not limited by space and time but able to be present how and when he wills; for Christ’s humanity can no longer be confined to earth, and belongs henceforth only to the Father’s divine realm.7 For this reason too the risen Jesus enjoys the sovereign freedom of appearing as he wishes: in the guise of a gardener or in other forms familiar to his disciples, precisely to awaken their faith.8

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.”9 Christ’s body was glorified at the moment of his Resurrection, as proved by the new and supernatural properties it subsequently and permanently enjoys.10 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.11 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.12 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.13

CIC 977 Our Lord tied the forgiveness of sins to faith and Baptism: “Go into all the world and preach the gospel to the whole creation. He who believes and is baptized will be saved.”14 Baptism is the first and chief sacrament of forgiveness of sins because it unites us with Christ, who died for our sins and rose for our justification, so that “we too might walk in newness of life.”15

CIC 1223 All the Old Covenant prefigurations find their fulfillment in Christ Jesus. He begins his public life after having himself baptized by St. John the Baptist in the Jordan.16 After his resurrection Christ gives this mission to his apostles: “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, teaching them to observe all that I have commanded you.”17
