I finally finished reading JPII's Evangelium Vitae (Gospel of Life) when I went on retreat last month. It is great and available here.
Here are some of my favorite quotes:
For this reason, man-living man-represents the primary and fundamental way for the Church. (n. 2)
At the same time a new cultural climate is developing and taking hold, which gives crimes against life a new and-if possible-even more sinister character, giving rise to further grave concern: broad sectors of public opinion justify certain crimes against life in the name of the rights of individual freedom, and on this basis they claim not only exemption from punishment but even authorization by the State, so that these things can be done with total freedom and indeed with the free assistance of health-care systems. (...) Even certain sectors of the medical profession, which by its calling is directed to the defence and care of human life, are increasingly willing to carry out these acts against the person. In this way the very nature of the medical profession is distorted and contradicted, and the dignity of those who practise it is degraded. (n. 4)
...respect, protect, love and serve life, every human life! Only in this direction will you find justice, development, true freedom, peace and happiness! (n. 5)
Looking at the situation from this point of view, it is possible to speak in a certain sense of a war of the powerful against the weak: a life which would require greater acceptance, love and care is considered useless, or held to be an intolerable burden, and is therefore rejected in one way or another. A person who, because of illness, handicap or, more simply, just by existing, compromises the well-being or life-style of those who are more favoured tends to be looked upon as an enemy to be resisted or eliminated. In this way a kind of "conspiracy against life" is unleashed. (n. 12)
Yes, every man is his "brother's keeper", because God entrusts us to one another. And it is also in view of this entrusting that God gives everyone freedom, a freedom which possesses an inherently relational dimension. (n. 19)
These requirements were already present in the Old Testament, where legislation dealt with protecting and defending life when it was weak and threatened: in the case of foreigners, widows, orphans, the sick and the poor in general, including children in the womb (cf. Ex 21:22; 22:20-26). With Jesus these positive requirements assume new force and urgency, and are revealed in all their breadth and depth: they range from caring for the life of one's brother (whether a blood brother, someone belonging to the same people, or a foreigner living in the land of Israel) to showing concern for the stranger, even to the point of loving one's enemy. (n. 41)
But in fact, "from the time that the ovum is fertilized, a life is begun which is neither that of the father nor the mother; it is rather the life of a new human being with his own growth. It would never be made human if it were not human already. (...) Precisely for this reason, over and above all scientific debates and those philosophical affirmations to which the Magisterium has not expressly committed itself, the Church has always taught and continues to teach that the result of human procreation, from the first moment of its existence, must be guaranteed that unconditional respect which is morally due to the human being in his or her totality and unity as body and spirit: "The human being is to be respected and treated as a person from the moment of conception; and therefore from that same moment his rights as a person must be recognized, among which in the first place is the inviolable right of every innocent human being to life". (n. 60)
All the same, "it is not right to deprive the dying person of consciousness without a serious reason": as they approach death people ought to be able to satisfy their moral and family duties, and above all they ought to be able to prepare in a fully conscious way for their definitive meeting with God. (n. 65)
True "compassion" leads to sharing another's pain; it does not kill the person whose suffering we cannot bear. Moreover, the act of euthanasia appears all the more perverse if it is carried out by those, like relatives, who are supposed to treat a family member with patience and love, or by those, such as doctors, who by virtue of their specific profession are supposed to care for the sick person even in the most painful terminal stages. (n. 66)
But would these crimes cease to be crimes if, instead of being committed by unscrupulous tyrants, they were legitimated by popular consensus?
Democracy cannot be idolized to the point of making it a substitute for morality or a panacea for immorality. (...) Even in participatory systems of government, the regulation of interests often occurs to the advantage of the most powerful, since they are the ones most capable of manoeuvering not only the levers of power but also of shaping the formation of consensus. In such a situation, democracy easily becomes an empty word. (n. 70)
