CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 1007–1011

1007 Death is the end of earthly life. Our lives are measured by time, in the course of which we change, grow old and, as with all living beings on earth, death seems like the normal end of life. That aspect of death lends urgency to our lives: remembering our mortality helps us realize that we have only a limited time in which to bring our lives to fulfillment:

Remember also your Creator in the days of your youth, . . . before the dust returns to the earth as it was, and the spirit returns to God who gave it.

1008 Death is a consequence of sin. The Church's Magisterium, as authentic interpreter of the affirmations of Scripture and Tradition, teaches that death entered the world on account of man's sin. Even though man's nature is mortal God had destined him not to die. Death was therefore contrary to the plans of God the Creator and entered the world as a consequence of sin. "Bodily death, from which man would have been immune had he not sinned" is thus "the last enemy" of man left to be conquered.
1009 Death is transformed by Christ. Jesus, the Son of God, also himself suffered the death that is part of the human condition. Yet, despite his anguish as he faced death, he accepted it in an act of complete and free submission to his Father's will. The obedience of Jesus has transformed the curse of death into a blessing.
1010 Because of Christ, Christian death has a positive meaning: "For to me to live is Christ, and to die is gain." "The saying is sure: if we have died with him, we will also live with him. What is essentially new about Christian death is this: through Baptism, the Christian has already "died with Christ" sacramentally, in order to live a new life; and if we die in Christ's grace, physical death completes this "dying with Christ" and so completes our incorporation into him in his redeeming act:

It is better for me to die in (eis) Christ Jesus than to reign over the ends of the earth. Him it is I seek - who died for us. Him it is I desire - who rose for us. I am on the point of giving birth. . . . Let me receive pure light; when I shall have arrived there, then shall I be a man.

1011 In death, God calls man to himself. Therefore the Christian can experience a desire for death like St. Paul's: "My desire is to depart and be with Christ." He can transform his own death into an act of obedience and love towards the Father, after the example of Christ:

My earthly desire has been crucified; . . . there is living water in me, water that murmurs and says within me: Come to the Father.

I want to see God and, in order to see him, I must die.

I am not dying; I am entering life.
