It is plausible that attitudes other than propositional belief are at the heart of religious practices. Believers are not solely concerned with holding religious content to be true. A strong version of this asserts that religious life can do without religious propositional beliefs, particularly in the use of religious language. Religious fictionalists accept religious language without believing in it, practicing it for pragmatic reasons. But to be rationally authorized, such use must be subject to an examination of the content conveyed by religious language. First, this examination is likely to be highly critical of the content, particularly with regard to the problem of evil and the problems associated with the leap of faith. Second, the conditions for the acceptability of religious language, namely a rational examination of the content conveyed, are contrary to a fundamental element of religious language, whose source, in one way or another, is not entirely human. Conclusion: religious fictionalism is inconsistent.
