Pope John Paul IIBelievers do not surrender. They can continue on their way to the truth because they are certain that God has created them "explorers", whose mission is to leave no stone unturned, though the temptation to doubt is always there. Leaning on God, they continue to reach out, always and everywhere, for all that is beautiful, good, and true.

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.
