Where, if not in the Divine Mercy, can the world find refuge and the light of hope?
Pope John Paul IIOne cannot use with impunity the different categories of beings-animals, plants, the natural elements-simply as one wishes, according to economic needs. One must take into account the nature of each being and its mutual connection in an ordered system, which is the cosmos.
Pope John Paul IIEvery scientist, through personal study and research, completes himself and his own humanity. ... Scientific research constitutes for you, as it does for many, the way for the personal encounter with truth, and perhaps the privileged place for the encounter itself with God, the Creator of heaven and earth. Science shines forth in all its value as a good capable of motivating our existence, as a great experience of freedom for truth, as a fundamental work of service. Through research each scientist grows as a human being and helps others to do likewise.
Pope John Paul IILaws which authorize and promote abortion and euthanasia are therefore radically opposed not only to the good of the individual but also to the common good; as such they are completely lacking in authentic juridical validity. Disregard for the right to life, precisely because it leads to the killing of the person whom society exists to serve, is what most directly conflicts with the possibility of achieving the common good. Consequently, a civil law authorizing abortion or euthanasia ceases by that very fact to be a true, morally binding civil law.
