**Abstract:** This article contributes to critical reflection on the political study approach towards the relations between religion and fundamentalism. In the context of post-secularism, in which the cognitive and moral role of religion for politics is quite widely recognised, the aim is to discuss three hypotheses. The first one argues that, contrary to what the majority of the subject's literature maintains, fundamentalism is not only a strictly religious phenomenon, but a specific attitude, able to evolve equally well on both religious and secular foundations. The second one implies that secularisation encourages, at least to an equal degree, both profane and religious fundamentalist tendencies. The third thesis asserts that religion, in its nature, constitutes a potential safeguard against fundamentalism. In the course of analysis, the pertinence of the above hypotheses are generally demonstrated. However, it is also indicated that the third point constitutes a mid-range theorem, accurately describing the contemporary specificity of Christianity, and especially Catholicism.
