A kind of cultural relativism exists today, evident in the conceptualization and defence of an ethical pluralism, which sanctions the decadence and disintegration of reason and the principles of the natural moral law. Furthermore, it is not unusual to hear the opinion expressed in the public sphere that such ethical pluralism is the very condition for democracy. As a result, citizens claim complete autonomy with regard to their moral choices, and lawmakers maintain that they are respecting this freedom of choice by enacting laws which ignore the principles of natural ethics and yield to ephemeral cultural and moral trends, as if every possible outlook on life were of equal value. At the same time, the value of tolerance is disingenuously invoked when a large number of citizens, Catholics among them, are asked not to base their contribution to society and political life – through the legitimate means available to everyone in a democracy – on their particular understanding of the human person and the common good. The history of the twentieth century demonstrates that those citizens were right who recognized the falsehood of relativism, and with it, the notion that there is no moral law rooted in the nature of the human person, which must govern our understanding of man, the common good and the state.

Such relativism, of course, has nothing to do with the legitimate freedom of Catholic citizens to choose among the various political opinions that are compatible with faith and the natural moral law, and to select, according to their own criteria, what best corresponds to the needs of the common good. Political freedom is not – and cannot be – based upon the relativistic idea that all conceptions of the human person’s good have the same value and truth, but rather, on the fact that politics are concerned with very concrete realizations of the true human and social good in given historical, geographic, economic, technological and cultural contexts. From the specificity of the task at hand and the variety of circumstances, a plurality of morally acceptable policies and solutions arises. It is not the Church’s task to set forth specific political solutions – and even less to propose a single solution as the acceptable one – to temporal questions that God has left to the free and responsible judgment of each person. It is, however, the Church’s right and duty to provide a moral judgment on temporal matters when this is required by faith or the moral law. If Christians must recognize the legitimacy of differing points of view about the organization of worldly affairs, they are also called to reject, as injurious to democratic life, a conception of pluralism that reflects moral relativism. Democracy must be based on the true and solid foundation of non-negotiable ethical principles, which are the underpinning of life in society. – from Participation of Catholics in Political Life (2002)
