One of the contemporary movements that has inspired the new discussions in religious epistemology is Reformed Epistemology. This movement is associated with Alvin Plantinga, Nicholas Wolterstorff, and William Alston. These philosophers have established some very fundamental challenges to the epistemology of religious belief that has dominated the Western thought since the Enlightenment. In contrast to the evidentialist tradition, Reformed Epistemology emphasizes that belief in God can have rationality, justification or warrant without being based on propositional evidence (argument). Some philosophers, such as Philip Quinn, deny the sufficiency of this justification for well-informed contemporary theists. Quinn argues that there are "defeaters" for the non-inferential justification of theistic belief, particularly the problem of evil, projective explanations of religion, and the problem of religious pluralism. The present research will explore the above issues, it and comes to the conclusion that for rational justification of belief in God for well-informed contemporary theists, additional positive argumentative supports are needed
