CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 1014–1017

1014 The Church encourages us to prepare ourselves for the hour of our death. In the ancient litany of the saints, for instance, she has us pray: "From a sudden and unforeseen death, deliver us, O Lord"; to ask the Mother of God to intercede for us "at the hour of our death" in the Hail Mary; and to entrust ourselves to St. Joseph, the patron of a happy death.

Every action of yours, every thought, should be those of one who expects to die before the day is out. Death would have no great terrors for you if you had a quiet conscience. . . . Then why not keep clear of sin instead of running away from death? If you aren't fit to face death today, it's very unlikely you will be tomorrow. . . .

Praised are you, my Lord, for our sister bodily Death,
from whom no living man can escape.
Woe on those who will die in mortal sin!
Blessed are they who will be found
in your most holy will,
for the second death will not harm them.

1015 "The flesh is the hinge of salvation" (Tertullian, De res. 8, 2: PL 2, 852). We believe in God who is creator of the flesh; we believe in the Word made flesh in order to redeem the flesh; we believe in the resurrection of the flesh, the fulfillment of both the creation and the redemption of the flesh.
1016 By death the soul is separated from the body, but in the resurrection God will give incorruptible life to our body, transformed by reunion with our soul. Just as Christ is risen and lives for ever, so all of us will rise at the last day.
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).
