Message of His Holiness Pope Francis to the Participants in the European Regional Meeting of the World Medical Association, 7 November 2017 – Regarding Euthanasia – it is morally licit to decide not to adopt therapeutic measures, or to discontinue them, when their use does not meet that ethical and humanistic standard that would later be called “due proportion in the use of remedies”  The Catechism of the Catholic Church makes this clear: “The decisions should be made by the patient if he is competent and able” (loc. cit.). The patient, first and foremost, has the right, obviously in dialogue with medical professionals, to evaluate a proposed treatment and to judge its actual proportionality in his or her concrete case, and necessarily refusing it if such proportionality is judged lacking.

• … euthanasia, which is always wrong, in that the intent of euthanasia is to end life and cause death.
