Abstract
In philosophical literature terms: „natural theology” (or „rational theology”) and „philosophical theology” are used as exchangeable. The author argues that natural and philosophical theology are different philosophical disciplines. It is possible to point out a philosophic theology, different from natural theology, the former aims are not only supposed to show that God exists but to unifícate, interpret and explain (understand) religious faith and her tasks are not primary apologetic. The author considers that the aims of the latter discipline are bound with the preference of cognitive values such as certainty, rationality and being able to use one ’s rationality to convince your opponent. In the end of this article author introduces a sketch of method of philosophical theology as different form natural theology, which could overcome one-sided views about role of philosophical argument in study of religious belief and faith and their propositional content and lead not only to a more adequate analysis of the researched reality but also to the development of other disciplines.
