Contrary to a widespread thesis about the non-cognitive character of religious beliefs, I argue that it is beneficial to highlight and not marginalize the place of religion in the epistemic sphere. At least some religious beliefs (especially theism) can be qualified as true or false. Holding them as true is usually based on the evidence which is not widely accepted. This, however, does not entail that these beliefs are not true. If they are true, then holding them to be true should be seen as rational, despite of the fact, that the supporting evidence does not seem to be strong in the light of current epistemic standards of justification. It does not mean, however, that such beliefs can be hold with the highest assertion if they evoke serious doubts. Changes in religious doctrines and religious pluralism do not constitute a sufficient reason for excluding religion from the epistemic sphere, as a similar situation concerns many academic disciplines, such as philosophy, or psychology.
