This article looks at the social doctrine of the Catholic Church. The God-given dignity of humans and the obligation to promote the common good of all the world's people require the Catholic Church to speak on social issues, says the new Compendium of the Social Doctrine of the Church. Drafted at the request of Pope John Paul II by the Pontifical Council for Justice and Peace, the compendium explains church teachings related to politics, war, the economy, the environment, work and legislation affecting family life, among other topics. Although the document states "A well-formed Christian conscience does not permit one to vote for a political program or individual law which contradicts the fundamental contents of faith and morals," Cardinal Renato Martino, president of the justice and peace council, refused to answer questions at a press conference about whether a Catholic ever could vote for a politician who supports legalized abortion. On the topic of war, the compendium says that when a nation is attacked it has a right and duty to defend itself. While based on 2,000 years of Christian moral teaching, the compendium says the church must respond to new situations in society, including the increasing number of women working outside the home, advances in biotechnology, globalization, the destruction of the environment and new attacks on human life and on the family. Rather it calls on Catholics and all people of good will to ensure that economic and political systems respect the rights of individuals, promote the common good and act in solidarity with the poorest and weakest citizens of their nation and of the world.
