Today's challenges

51. And how can we remain indifferent to the prospect of an ecological crisis which is making vast areas of our planet uninhabitable and hostile to humanity? Or by the problems of peace, so often threatened by the spectre of catastrophic wars? Or by contempt for the fundamental human rights of so many people, especially children? Countless are the emergencies to which every Christian heart must be sensitive.

A special commitment is needed with regard to certain aspects of the Gospel's radical message which are often less well understood, even to the point of making the Church's presence unpopular, but which nevertheless must be a part of her mission of charity. I am speaking of the duty to be committed to respect for the life of every human being, from conception until natural death. Likewise, the service of humanity leads us to insist, in season and out of season, that those using the latest advances of science, especially in the field of biotechnology, must never disregard fundamental ethical requirements by invoking a questionable solidarity which eventually leads to discriminating between one life and another and ignoring the dignity which belongs to every human being.

For Christian witness to be effective, especially in these delicate and controversial areas, it is important that special efforts be made to explain properly the reasons for the Church's position, stressing that it is not a case of imposing on non-believers a vision based on faith, but of interpreting and defending the values rooted in the very nature of the human person. In this way charity will necessarily become service to culture, politics, the economy and the family, so that the fundamental principles upon which depend the destiny of human beings and the future of civilization will be everywhere respected.
