I have copied several wonderful quotes from the Vatican website after searching and reading extensively on the subject. What continued to be stated over and over were the words “until NATURAL death”.
“There is a growing exchange of ideas, but the very words by which key concepts are expressed take on quite different meanings in diverse ideological systems. Finally, man painstakingly searches for a better world, without a corresponding spiritual advancement.”
"Christians are called to be active in the real world of today: uncertain and changing, tempted to sacrifice transcendence to immanence and the supreme values to prosperity, they are also prompted to take refuge in pragmatic and utilitarian conventionalism, rather than to ally themselves with truth and reason. However, our hope is based not only on help from the Lord of life but also on the conviction that the sacred value of human life can be recognized in the natural law alone, written in the human heart, disregard for which is at the root “of a tragic obscuring of the collective conscience” (Evangelium vitae, n. 70).
" The changing of laws must be preceded and accompanied by the changing of mentalities and morals on a vast scale, in an extensive and visible way. In this area the Church will spare no effort nor can she accept negligence or guilty silence" (ibid., n. 6).
We, academicians, fully agreed with the Holy Father’s statement that “there is no reason for that type of defeatist mentality which claims that laws opposed to the right to life - those which legalize abortion, euthanasia, sterilization and methods of family planning opposed to life and the dignity of marriage - are inevitable and now almost a social necessity. On the contrary, they are a seed of corruption for society and its foundations. The civil and moral conscience cannot accept this false inevitability, any more than the idea that war or interethnic extermination is inevitable” (ibid.).
