'To save means to liberate from evil. This does not refer only to social evils, such as injustice, coercion, exploitation. Nor does it refer only to disease, catastrophes, natural cataclysms, and everything that has been considered disaster in the history of humanity.
'To save means to liberate from radical, ultimate evil. Death itself is no longer that kind of evil, if followed by the Resurrection. And the Resurrection comes about through the work of Christ. Through the work of the Redeemer death ceases to be an ultimate evil; it becomes subject to the power of life.
'The world does not have such power. The world, which is capable of perfecting therapeutic techniques in various fields, does not have the power to liberate man from death. And therefore the world cannot be a source of salvation for man. Only God saves, and He saves the whole of humanity in Christ.'
Pope John Paul II, Crossing the Threshold of Hope
