Abstract
The atheism of Marx, Nietzsche, and Freud can be called the atheism of suspicion in contrast to evidential atheism. For while the latter focuses on the truth of religious beliefs, the former inquires into their function. It asks, in other words, what motives lead to belief and what practices are compatible with and authorised by religious beliefs. The primary response of Christian philosophers should not be to refute these analyses, since they are all too often true and, moreover, very much of the same sort as found in the religion critique of Jesus and the prophets. Rather, our primary response should be to show the Christian community, including ourselves, how even the truth can become an instrument of self-interest. In this way the atheism of suspicion can provide helpful conceptual tools for personal and corporate self-examination.
