Abstract
My aim in this paper is to show that some parts of J. M. Bocheński’s account of the logic of religion are useful for epistemological investigation of a religious belief, particularly for the questions of realistic and cognitive interpretations of a religious discourse, the problems of justification and warrant of a religious belief and for the problem of the place of criticism in a religious discourse. Referring to Bocheński's understanding of the structure of religious/theological thinking, I present the criteria for the gradual rationality of religion and claim that religions may differ in rationality and that there may be a rational and critical religion that uses the achievements of science and philosophy - contrary to what the New Atheists claim.
