The Church recognizes that while democracy is the best expression of the direct participation of citizens in political choices, it succeeds only to the extent that it is based on a correct understanding of the human person. Catholic involvement in political life cannot compromise on this principle, for otherwise the witness of the Christian faith in the world, as well as the unity and interior coherence of the faithful, would be non-existent. The democratic structures on which the modern state is based would be quite fragile were its foundation not the centrality of the human person. It is respect for the person that makes democratic participation possible. As the Second Vatican Council teaches, the protection of “the rights of the person is, indeed, a necessary condition for citizens, individually and collectively, to play an active part in public life and administration”.
The complex array of today’s problems branches out from here, including some never faced by past generations. Scientific progress has resulted in advances that are unsettling for the consciences of men and women and call for solutions that respect ethical principles in a coherent and fundamental way. At the same time, legislative proposals are put forward which, heedless of the consequences for the existence and future of human beings with regard to the formation of culture and social behaviour, attack the very inviolability of human life. Catholics, in this difficult situation, have the right and the duty to recall society to a deeper understanding of human life and to the responsibility of everyone in this regard. John Paul II, continuing the constant teaching of the Church, has reiterated many times that those who are directly involved in lawmaking bodies have a “grave and clear obligation to oppose” any law that attacks human life. For them, as for every Catholic, it is impossible to promote such laws or to vote for them. As John Paul II has taught in his Encyclical Letter Evangelium vitae regarding the situation in which it is not possible to overturn or completely repeal a law allowing abortion which is already in force or coming up for a vote, “an elected official, whose absolute personal opposition to procured abortion was well known, could licitly support proposals aimed at limiting the harm done by such a law and at lessening its negative consequences at the level of general opinion and public morality”.
