CCC 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”;1 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. ..2
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.3
