By calling into question the very ideal of a universal, autonomous reason (which was, in the Enlightenment, the basis for rejecting religious thought) and further demonstrating that all knowledge is grounded in narrative or myth, Lyotard relativizes (secular) philosophy's claim to autonomy and so grants the legitimacy of a philosophy that grounds itself in Christian faith. Previously such a distinctly Christian philosophy would have been exiled from the 'pure' arena of philosophy because of its 'infection' with bias and prejudice. Lyotard's critique, however, demonstrates that no philosophy - indeed, no knowledge - is untainted by prejudice or faith commitments. In this way the playing field is leveled, and new opportunities to voice a Christian philosophy are created. Thus Lyotard's postmodern critique of metanarratives, rather than being a formidable foe of Christian faith and thought, can in fact be enlisted as an ally in the construction of a Christian philosophy.
