CCC 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.1 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.2 “Bodily death, from which man would have been immune had he not sinned” is thus “the last enemy” of man left to be conquered.3
