From Pope St. John Paul II’s Apostolic Exhortation Familiaris Consortio (1981):
The teaching of the Church in our day is placed in a social and cultural context which renders it more difficult to understand and yet more urgent and irreplaceable for promoting the true good of men and women.
Scientific and technical progress, which contemporary man is continually expanding in his dominion over nature, not only offers the hope of creating a new and better humanity, but also causes ever greater anxiety regarding the future. Some ask themselves if it is a good thing to be alive or if it would be better never to have been born; they doubt therefore if it is right to bring others into life when perhaps they will curse their existence in a cruel world with unforeseeable terrors. Others consider themselves to be the only ones for whom the advantages of technology are intended and they exclude others by imposing on them contraceptives or even worse means. Still others, imprisoned in a consumer mentality and whose sole concern is to bring about a continual growth of material goods, finish by ceasing to understand, and thus by refusing, the spiritual riches of a new human life. The ultimate reason for these mentalities is the absence in people’s hearts of God, whose love alone is stronger than all the world’s fears and can conquer them.
Thus an anti-life mentality is born, as can be seen in many current issues: one thinks, for example, of a certain panic deriving from the studies of ecologists and futurologists on population growth, which sometimes exaggerate the danger of demographic increase to the quality of life.
But the Church firmly believes that human life, even if weak and suffering, is always a splendid gift of God’s goodness. Against the pessimism and selfishness which cast a shadow over the world, the Church stands for life: in each human life she sees the splendor of that “Yes,” that “Amen,” who is Christ Himself.84 To the “No” which assails and afflicts the world, she replies with this living “Yes,” thus defending the human person and the world from all who plot against and harm life.
The Church is called upon to manifest anew to everyone, with clear and stronger conviction, her will to promote human life by every means and to defend it against all attacks, in whatever condition or state of development it is found.
Thus the Church condemns as a grave offense against human dignity and justice all those activities of governments or other public authorities which attempt to limit in any way the freedom of couples in deciding about children. Consequently, any violence applied by such authorities in favor of contraception or, still worse, of sterilization and procured abortion, must be altogether condemned and forcefully rejected. Likewise to be denounced as gravely unjust are cases where, in international relations, economic help given for the advancement of peoples is made conditional on programs of contraception, sterilization and procured abortion.85
