Just finished reading it.
I recommend it to anyone. The main point to be driven home is that the Pope finally made explicit what was always implicit in Catholic teaching: you cannot be for poor people, the environment or social justice unless you are first and foremost pro-life.
Finally seeing it in black and white, is just awesome.
Bottom line, one cannot use the "social justice" issues to ever outweigh being 100% pro-life, because being 100% pro-life is the only legitimate and authentic way to pursue social justice. Any other program, that denies the right to life, will lead to disaster and human destruction.
"One of the most striking aspects of development in the present day is the important question of respect for life, which cannot in any way be detached from questions concerning the development of peoples. It is an aspect which has acquired increasing prominence in recent times, obliging us to broaden our concept of poverty and underdevelopment to include questions connected with the acceptance of life, especially in cases where it is impeded in a variety of ways. . . . Openness to life is at the centre of true development. When a society moves towards the denial or suppression of life, it ends up no longer finding the necessary motivation and energy to strive for man's true good. If personal and social sensitivity towards the acceptance of a new life is lost, then other forms of acceptance that are valuable for society also wither away. The acceptance of life strengthens moral fibre and makes people capable of mutual help. By cultivating openness to life, wealthy peoples can better understand the needs of poor ones, they can avoid employing huge economic and intellectual resources to satisfy the selfish desires of their own citizens, and instead, they can promote virtuous action within the perspective of production that is morally sound and marked by solidarity, respecting the fundamental right to life of every people and every individual." Caritas in veritate Paragraph 28
"If there is a lack of respect for the right to life and to a natural death, if human conception, gestation and birth are made artificial, if human embryos are sacrificed to research, the conscience of society ends up losing the concept of human ecology and, along with it, that of environmental ecology. It is contradictory to insist that future generations respect the natural environment when our educational systems and laws do not help them to respect themselves. The book of nature is one and indivisible: it takes in not only the environment but also life, sexuality, marriage, the family, social relations: in a word, integral human development. Our duties towards the environment are linked to our duties towards the human person, considered in himself and in relation to others. It would be wrong to uphold one set of duties while trampling on the other. Herein lies a grave contradiction in our mentality and practice today: one which demeans the person, disrupts the environment and damages society." Paragraph 51
