Excerpt from the Church's document on certain issues regarding procreation, Dignitas Personae: On Certain Bioethical Questions (September 2008). Here is last part of the conclusion. (The numbers below correspond to the numbers at the beginning of each section in the official document).
37 If initially human and social progress was characterized primarily by industrial development and the production of consumer goods, today it is distinguished by developments in information technologies, research in genetics, medicine and biotechnologies for human benefit, which are areas of great importance for the future of humanity, but in which there are also evident and unacceptable abuses. "Just as a century ago it was the working classes which were oppressed in their fundamental rights, and the Church courageously came to their defense by proclaiming the sacrosanct rights of the worker as person, so now, when another category of persons is being oppressed in the fundamental right to life, the Church feels in duty bound to speak out with the same courage on behalf of those who have no voice. Hers is always the evangelical cry in defense of the world's poor, those who are threatened and despised and whose human rights are violated". 559
In virtue of the Church's doctrinal and pastoral mission, the Congregation for the Doctrine of the Faith has felt obliged to reiterate both the dignity and the fundamental and inalienable rights of every human being, including those in the initial stages of their existence, and to state explicitly the need for protection and respect which this dignity requires of everyone.
The fulfillment of this duty implies courageous opposition to all those practices which result in grave and unjust discrimination against unborn human beings, who have the dignity of a person, created like others in the image of God. Behind every "no" in the difficult task of discerning between good and evil, there shines a great "yes" to the recognition of the dignity and inalienable value of every single and unique human being called into existence.
The Christian faithful will commit themselves to the energetic promotion of a new culture of life by receiving the contents of this Instruction with the religious assent of their spirit, knowing that God always gives the grace necessary to observe his commandments and that, in every human being, above all in the least among us, one meets Christ himself (cf. Mt 25:40). In addition, all persons of good will, in particular physicians and researchers open to dialogue and desirous of knowing what is true, will understand and agree with these principles and judgments, which seek to safeguard the vulnerable condition of human beings in the first stages of life and to promote a more human civilization.
The Sovereign Pontiff Benedict XVI, in the Audience granted to the undersigned Cardinal Prefect on 20 June 2008, approved the present Instruction, adopted in the Ordinary Session of this Congregation, and ordered its publication.
Rome, from the Offices of the Congregation for the Doctrine of the Faith, 8 September 2008, Feast of the Nativity of the Blessed Virgin Mary.
