Paragraph 3. Jesus Christ was Buried
624 "By the grace of God" Jesus tasted death "for every one".459 In his plan of salvation, God ordained that his Son should not only "die for our sins"460 but should also "taste death", experience the condition of death, the separation of his soul from his body, between the time he expired on the cross and the time he was raised from the dead. The state of the dead Christ is the mystery of the tomb and the descent into hell. It is the mystery of Holy Saturday, when Christ, lying in the tomb,461 reveals God's great sabbath rest462 after the fulfillment463 of man's salvation, which brings peace to the whole universe.464
625 Christ's stay in the tomb constitutes the real link between his passible state before Easter and his glorious and risen state today. The same person of the "Living One" can say, "I died, and behold I am alive for evermore":465
626 Since the "Author of life" who was killed467 is the same "living one [who has] risen",468 the divine person of the Son of God necessarily continued to possess his human soul and body, separated from each other by death:
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"470 and therefore "divine power preserved Christ's body from corruption."471 Both of these statements can be said of Christ: "He was cut off out of the land of the living",472 and "My flesh will dwell in hope. For you will not abandon my soul to Hades, nor let your Holy One see corruption."473 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.474
628 Baptism, the original and full sign of which is immersion, efficaciously signifies the descent into the tomb by the Christian who dies to sin with Christ in order to live a new life. "We were buried therefore with him by baptism into death, so that as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life."475
630 During Christ's period in the tomb, his divine person continued to assume both his soul and his body, although they were separated from each other by death. For this reason the dead Christ's body "saw no corruption" (Acts 13:37).
