In this paper I focus on one of the fundamental democratic freedoms – freedom of conscience – and see to what extent Catholicism is compatible or consistent with it and, by extension, with democracy in civil or political institutions. I draw primarily on recent ecclesial statements on the issue, but also on the philosophical views of Jacques Maritain. First, I outline briefly the view of democracy and freedom of conscience that putatively undergirds modern democratic societies, as well as the understanding of this freedom in Catholic thought. Next, I present the claim that there are some important differences in the way in which this freedom is described in Catholicism as distinct from dominant, secular democratic views. Third, I suggest that these differences, while real, do not sustain the claim of a radical difference in principle between freedom of conscience in recent Catholic thought and that found in documents such as the Universal Declaration of Human Rights. I conclude that not only is the Catholic approach to freedom of conscience compatible with democracy in civil institutions, but democratic government may be an important way to develop values recognized by Catholicism as fundamental.
