CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 637–641

637 In his human soul united to his divine person, the dead Christ went down to the realm of the dead. He opened heaven's gates for the just who had gone before him.
638 "We bring you the good news that what God promised to the fathers, this day he has fulfilled to us their children by raising Jesus." The Resurrection of Jesus is the crowning truth of our faith in Christ, a faith believed and lived as the central truth by the first Christian community; handed on as fundamental by Tradition; established by the documents of the New Testament; and preached as an essential part of the Paschal mystery along with the cross:

Christ is risen from the dead!
Dying, he conquered death;
To the dead, he has given life.

639 The mystery of Christ's resurrection is a real event, with manifestations that were historically verified, as the New Testament bears witness. In about A.D. 56 St. Paul could already write to the Corinthians: "I delivered to you as of first importance what I also received, that Christ died for our sins in accordance with the scriptures, and that he was buried, that he was raised on the third day in accordance with the scriptures, and that he appeared to Cephas, then to the Twelve. . ." The Apostle speaks here of the living tradition of the Resurrection which he had learned after his conversion at the gates of Damascus.
640 "Why do you seek the living among the dead? He is not here, but has risen." The first element we encounter in the framework of the Easter events is the empty tomb. In itself it is not a direct proof of Resurrection; the absence of Christ's body from the tomb could be explained otherwise. Nonetheless the empty tomb was still an essential sign for all. Its discovery by the disciples was the first step toward recognizing the very fact of the Resurrection. This was the case, first with the holy women, and then with Peter. The disciple "whom Jesus loved" affirmed that when he entered the empty tomb and discovered "the linen cloths lying there", "he saw and believed". This suggests that he realized from the empty tomb's condition that the absence of Jesus' body could not have been of human doing and that Jesus had not simply returned to earthly life as had been the case with Lazarus.
641 Mary Magdalene and the holy women who came to finish anointing the body of Jesus, which had been buried in haste because the Sabbath began on the evening of Good Friday, were the first to encounter the Risen One. Thus the women were the first messengers of Christ's Resurrection for the apostles themselves. They were the next to whom Jesus appears: first Peter, then the Twelve. Peter had been called to strengthen the faith of his brothers, and so sees the Risen One before them; it is on the basis of his testimony that the community exclaims: "The Lord has risen indeed, and has appeared to Simon!"
