CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 1017–1021

1017 "We believe in the true resurrection of this flesh that we now possess" (Council of Lyons II: DS 854). We sow a corruptible body in the tomb, but he raises up an incorruptible body, a "spiritual body" (cf. 1 Cor 15:42-44).
1018 As a consequence of original sin, man must suffer "bodily death, from which man would have been immune had he not sinned" (GS § 18).
1019 Jesus, the Son of God, freely suffered death for us in complete and free submission to the will of God, his Father. By his death he has conquered death, and so opened the possibility of salvation to all men.
1020 The Christian who unites his own death to that of Jesus views it as a step towards him and an entrance into everlasting life. When the Church for the last time speaks Christ's words of pardon and absolution over the dying Christian, seals him for the last time with a strengthening anointing, and gives him Christ in viaticum as nourishment for the journey, she speaks with gentle assurance:

Go forth, Christian soul, from this world
in the name of God the almighty Father,
who created you,
in the name of Jesus Christ, the Son of the living God,
who suffered for you,
in the name of the Holy Spirit,
who was poured out upon you.
Go forth, faithful Christian!
May you live in peace this day,
may your home be with God in Zion,
with Mary, the virgin Mother of God,
with Joseph, and all the angels and saints. . . .
May you return to [your Creator]
who formed you from the dust of the earth.
May holy Mary, the angels, and all the saints
come to meet you as you go forth from this life. . . .
May you see your Redeemer face to face.

1021 Death puts an end to human life as the time open to either accepting or rejecting the divine grace manifested in Christ. The New Testament speaks of judgment primarily in its aspect of the final encounter with Christ in his second coming, but also repeatedly affirms that each will be rewarded immediately after death in accordance with his works and faith. The parable of the poor man Lazarus and the words of Christ on the cross to the good thief, as well as other New Testament texts speak of a final destiny of the soul -- a destiny which can be different for some and for others.
