All society "is called to respect the life and dignity of the seriously ill and the dying", said the Holy Father. "Though aware of the fact that 'it is not science that redeems man', all society, and in particular the sectors associated with medical science, are duty bound to express the solidarity of love, and to safeguard and respect human life in every moment of its earthly development, especially when it is ill or in its terminal stages.
"In more concrete terms", he added, "this means ensuring that every person in need finds the necessary support through appropriate treatments and medical procedures - identified and administered using criteria of therapeutic proportionality - while bearing in mind the moral duty to administer (on the part of doctors) and to accept (on the part of patients) those means for preserving life which, in a particular situation, may be considered as 'ordinary'".
As for forms of treatment "with significant levels of risk or that may reasonably be judged to be 'extraordinary', recourse thereto may be considered as morally acceptable, but optional. Furthermore, it will always be necessary to ensure that everyone has the treatment they require, and that families tried by the sickness of one of their members receive support, especially if the sickness is serious or prolonged".
